Controls &
Components
To reduce your risk of
serious injury, read this
entire manual BEFORE
using machine.
G. Planer Table Height Crank: Raises and
lowers planer table to accommodate differ-
ent workpiece thicknesses. Each full rotation
changes height approximately
1
⁄8".
H. Jointer Infeed Table: Supports workpiece
before it reaches cutterhead. Position of
infeed table relative to cutterhead determines
depth of cut.
Main Controls & Components
A. Jointer Outfeed Table: Supports workpiece
after it passes over cutterhead.
B. Cutterhead Guard: Covers cutterhead until
pushed out of the way by workpiece during
jointing operations. When workpiece leaves
cutterhead, guard springs back to its starting
position.
C. Fence: Guides workpiece as it moves across
cutterhead; determines angle of cut.
Refer to the following figures and descriptions to
become familiar with the basic controls and com-
ponents of this machine. Understanding these
items and how they work will help you understand
the rest of the manual and minimize your risk of
injury when operating this machine.
Figure 2. Main controls & components (right).
D. Circuit Breaker Reset Button: Allows
machine to be restarted after thermal over-
load protection has tripped. To reset, place
ON/OFF switch in OFF position, wait a few
minutes for motor to cool, then press reset
button. If button does not stay depressed,
allow motor to cool longer, then try again.
E. Planer Thickness Scale: Shows height of
cutterhead above planer table. Measurement
indicated by red line shows effective thick-
ness of board after planing.
F. Dust Port Housing: Installs beneath outfeed
table for jointer operations; installs above
outfeed table for planer operations. Two keys
secure dust port to table.
Note: Machine will not start if keys on dust
port housing are not installed in slots on
outfeed table.

Internal Components (Planer)
A. Infeed Roller: Rotates with direction of feed
to pull workpiece toward cutterhead.
B
. Cutterhead: Holds inserts that remove mate-
rial from workpiece. Rotates opposite direc-
tion of feed.
C.
Chip Deflector: Directs chips into dust port.
D.
Outfeed Roller: Rotates with direction of
feed to pull workpiece through planer.
E
. Planer Table: Provides a smooth, flat sur-
face for workpiece to slide against as it
moves through planer.
Like all machinery there is potential danger
when operating this machine. Accidents
are frequently caused by lack of familiarity
or failure to pay attention. Use this machine
with respect and caution to decrease the
risk of operator injury. If normal safety pre-
cautions are overlooked or ignored, seri-
ous personal injury may occur.

No list of safety guidelines can be com-
plete. Every shop environment is different.
Always consider safety first, as it applies
to your individual working conditions. Use
this and other machinery with caution and
respect. Failure to do so could result in
serious personal injury, damage to equip-
ment, or poor work results.

ELECTRICAL EQUIPMENT INJURY RISKS.
You can be shocked, burned, or killed by touching
live electrical components or improperly grounded
machinery. To reduce this risk, only allow qualified
service personnel to do electrical installation or
repair work, and always disconnect power before
accessing or exposing electrical equipment.
DISCONNECT POWER FIRST.
Always discon-
nect machine from power supply BEFORE mak-
ing adjustments, changing tooling, or servicing
machine. This prevents an injury risk from unin-
tended startup or contact with live electrical com-
ponents.
EYE PROTECTION. Always wear ANSI-approved
safety glasses or a face shield when operating or
observing machinery to reduce the risk of eye
injury or blindness from flying particles. Everyday
eyeglasses are NOT approved safety glasses.
OWNER’S MANUAL. Read and understand this
owner’s manual BEFORE using machine.
TRAINED OPERATORS ONLY. Untrained oper-

WEARING PROPER APPAREL. Do not wear
clothing, apparel or jewelry that can become
entangled in moving parts. Always tie back or
cover long hair. Wear non-slip footwear to reduce
risk of slipping and losing control or accidentally
contacting cutting tool or moving parts.
HAZARDOUS DUST. Dust created by machinery
operations may cause cancer, birth defects, or
long-term respiratory damage. Be aware of dust
hazards associated with each workpiece mate-
rial. Always wear a NIOSH-approved respirator to
reduce your risk.
HEARING PROTECTION. Always wear hear-
ing protection when operating or observing loud
machinery. Extended exposure to this noise
without hearing protection can cause permanent
hearing loss.
REMOVE ADJUSTING TOOLS. Tools left on
machinery can become dangerous projectiles
upon startup. Never leave chuck keys, wrenches,
or any other tools on machine. Always verify
removal before starting!
USE CORRECT TOOL FOR THE JOB. Only use
this tool for its intended purpose—do not force
it or an attachment to do a job for which it was
not designed. Never make unapproved modifica-
tions—modifying tool or using it differently than
intended may result in malfunction or mechanical
failure that can lead to personal injury or death!
AWKWARD POSITIONS. Keep proper footing
and balance at all times when operating machine.
Do not overreach! Avoid awkward hand positions
that make workpiece control difficult or increase
the risk of accidental injury.
CHILDREN & BYSTANDERS. Keep children and
bystanders at a safe distance from the work area.
Stop using machine if they become a distraction.
GUARDS & COVERS. Guards and covers reduce
accidental contact with moving parts or flying
debris. Make sure they are properly installed,
undamaged, and working correctly BEFORE
operating machine.
FORCING MACHINERY. Do not force machine.
It will do the job safer and better at the rate for
which it was designed.
NEVER STAND ON MACHINE. Serious injury
may occur if machine is tipped or if the cutting
tool is unintentionally contacted.
STABLE MACHINE. Unexpected movement dur-
ing operation greatly increases risk of injury or
loss of control. Before starting, verify machine is

Additional Safety for Jointers
KICKBACK. Occurs when workpiece is ejected
from machine at a high rate of speed. Kickback
injuries occur from getting struck by workpiece or
hands being pulled into cutterhead. To reduce the
risk of kickback, only use proper workpieces, safe
feeding techniques, and proper machine setup or
maintenance.
GUARD REMOVAL. Operating jointer without
guards unnecessarily exposes operator to knives/
inserts and other hazardous moving parts. Except
when rabbeting, never operate jointer or allow it to
be connected to power if any guards are removed.
Turn jointer OFF and disconnect power before
clearing any shavings or sawdust from around
cutterhead. After rabbeting or maintenance is
complete, immediately replace all guards and
ensure they are properly installed/adjusted before
resuming regular operations.
DULL OR DAMAGED KNIVES/INSERTS. Dull or
damaged knives/inserts increase risk of kickback
and cause poor workpiece finish. Only use sharp,
undamaged knives/inserts.
OUTFEED TABLE ALIGNMENT. Setting outfeed
table too high can cause workpiece to hit table or
get stuck while feeding. Setting outfeed table too
low may cause workpiece to rock or shift while
feeding. Both of these results will increase risk
of kickback. Always keep outfeed table even with
knives/inserts at highest point during rotation.
INSPECTING STOCK. Impact injuries or kick-
back may result from using improper workpieces.
Thoroughly inspect and prepare workpiece before
cutting. Verify workpiece is free of nails, staples,
loose knots or other foreign material. Always joint
warped workpieces with cupped side facing down.
MAXIMUM CUTTING DEPTH. To reduce risk of
kickback, never cut deeper than
1
⁄16" per pass.
GRAIN DIRECTION. Jointing against the grain
or end grain can increase risk of kickback. It also
requires more cutting force, which produces chat-
ter or excessive chip out. Always joint or surface
plane WITH the grain.
CUTTING LIMITATIONS. Cutting workpieces that
do not meet minimum dimension requirements
can result in kickback or accidental contact with
cutterhead. Never perform jointing, planing, or
rabbeting cuts on pieces smaller than specified in
machine data sheet.
PUSH BLOCKS. Push blocks reduce risk of acci-
dental cutterhead contact with hands. Always use
push blocks when planing materials less than 3"
high or wide. Never pass your hands directly over
cutterhead without a push block.
WORKPIECE SUPPORT. Poor workpiece sup-
port or loss of workpiece control while feeding will
increase risk of kickback or accidental contact
with cutterhead. Support workpiece with fence
continuously during operation. Support long stock
with auxiliary tables if necessary.
FEED WORKPIECE PROPERLY. Kickback
or accidental cutterhead contact may result if
workpiece is fed into cutterhead the wrong way.
Allow cutterhead to reach full speed before feed-
ing. Never start jointer with workpiece touching
cutterhead. Always feed workpiece from infeed
side to outfeed side without stopping until cut is
complete. Never move workpiece backwards while
feeding.
SECURE KNIVES/INSERTS. Loose knives
or improperly set inserts can be thrown from
cutterhead with dangerous force. Always verify
knives/inserts are secure and properly adjusted
before operation. Straight knives should never proj-
ect more than
1
⁄8" (0.125") from cutterhead body.
Serious cuts, amputation, entanglement, or death can occur from contact with rotating cutterhead
or other moving components! Flying chips from cutting operations can cause eye injuries or
blindness. Workpieces or inserts/knives thrown by cutterhead (kickback) can strike nearby
operator or bystanders with deadly force. To reduce the risk of serious personal injury from these
hazards, operator and bystanders MUST completely heed the hazards and warnings below.
-16 -
Model G0958/G0959 (Mfd. Since 03/23)
Additional Safety for Planers
Amputation, serious cuts, entanglement, or death can occur from contact with rotating
cutterhead or other moving parts! Flying chips can cause eye injuries or blindness. Workpieces
or knives thrown by cutterhead can strike nearby operator or bystanders with deadly force. To
reduce the risk of these hazards, operator and bystanders MUST completely heed hazards and
warnings below.
PLANING CORRECT MATERIAL. Only plane
natural wood stock with this planer. DO NOT
plane MDF, OSB, plywood, laminates or other
synthetic materials that can break up inside the
planer and be ejected towards the operator.
LOOKING INSIDE PLANER. Wood chips fly
around inside the planer at a high rate of speed
during operation. To avoid injury from flying mate-
rial, DO NOT look inside planer during operation.
CUTTING LIMITATIONS. To reduce the risk of
kickback hazards or damage to the machine, do
not exceed the maximum depth of cut or minimum
board length and thickness found in the Data
Sheet. Only feed one board at a time.
INFEED ROLLER CLEARANCE. The infeed
roller is designed to pull material into the spinning
cutterhead. To reduce the risk of entanglement,
keep hands, clothing, jewelry, and long hair away
from the infeed roller during operation.
FEED WORKPIECE PROPERLY. To reduce the
risk of kickback, never start planer with workpiece
touching cutterhead. Allow cutterhead to reach
full speed before feeding, and do not change feed
speed during cutting operation.
WORKPIECE SUPPORT. To reduce the risk of
kickback, always make sure workpiece can move
completely across table without rocking or tipping.
Use auxiliary support stands for long stock.
SECURE KNIVES/INSERTS. Loose knives or
improperly set inserts can become dangerous
projectiles or cause machine damage. Always
verify knives/inserts are secure and properly
adjusted before operation.
KICKBACK. Know how to reduce risk of kickback
and kickback-related injuries. “Kickback” occurs
during operation when the workpiece is ejected
back through infeed side of machine at a high
rate of speed. Kickback is commonly caused by
poor workpiece selection, unsafe feeding tech-
niques, or improper machine setup/maintenance.
Kickback injuries typically occur as follows: (1)
operator/bystanders are struck by workpiece,
resulting in impact injuries (i.e., blindness, broken
bones, bruises, death); (2) operator’s hands are
pulled into blade from outfeed side, resulting in
amputation or severe lacerations.
AVOID CONTACT WITH MOVING PARTS. Never
remove guards/covers or reach inside planer dur-
ing operation or while connected to power. You
could be seriously injured if you accidentally touch
spinning cutterhead or get entangled in moving
parts. If a workpiece becomes stuck or sawdust
removal is necessary, turn planer OFF, allow cut-
terhead to stop, disconnect power before clearing.
DULL/DAMAGED KNIVES/INSERTS. Only use
sharp, undamaged knives/inserts. Dull or dam-
aged knives/inserts increase the risk of kickback.
INSPECTING STOCK. To reduce the risk of
kickback injuries or machine damage, thoroughly
inspect and prepare the workpiece before cutting.
Verify workpiece is free of nails, staples, loose
knots, or foreign material. Workpieces with minor
warping should be jointed first or planed with the
cupped side facing the table.
BODY PLACEMENT. Stand to one side of planer
during entire operation to avoid getting hit if kick-
back occurs.
GRAIN DIRECTION. Planing across grain is hard
on planer and may cause kickback. Plane in same
direction or at a slight angle with wood grain.

SECTION 2: POWER SUPPLY
Availability
Before installing the machine, consider the avail-
ability and proximity of the required power supply
circuit. If an existing circuit does not meet the
requirements for this machine, a new circuit must
be installed. To minimize the risk of electrocution,
fire, or equipment damage, installation work and
electrical wiring must be done by an electrician or
qualified service personnel in accordance with all
applicable codes and standards.
Electrocution, fire, shock,
or equipment damage
may occur if machine is
not properly grounded
and connected to power
supply.
Full-Load Current Rating
The full-load current rating is the amperage a
machine draws at 100% of the rated output power.
On machines with multiple motors, this is the
amperage drawn by the largest motor or sum of all
motors and electrical devices that might operate
at one time during normal operations.
Full-Load Current Rating at 120V ..... 15 Amps
The full-load current is not the maximum amount
of amps that the machine will draw. If the machine
is overloaded, it will draw additional amps beyond
the full-load rating.
If the machine is overloaded for a sufficient length
of time, damage, overheating, or fire may result—
especially if connected to an undersized circuit.
To reduce the risk of these hazards, avoid over-
loading the machine during operation and make
sure it is connected to a power supply circuit that
meets the specified circuit requirements.
For your own safety and protection of
property, consult an electrician if you are
unsure about wiring practices or electrical
codes in your area.
Note: Circuit requirements in this manual apply to
a dedicated circuit—where only one machine will
be running on the circuit at a time. If machine will
be connected to a shared circuit where multiple
machines may be running at the same time, con-
sult an electrician or qualified service personnel to
ensure circuit is properly sized for safe operation.
A power supply circuit includes all electrical
equipment between the breaker box or fuse panel
in the building and the machine. The power sup-
ply circuit used for this machine must be sized to
safely handle the full-load current drawn from the
machine for an extended period of time. (If this
machine is connected to a circuit protected by
fuses, use a time delay fuse marked D.)
Circuit Requirements
This machine is prewired to operate on a power
supply circuit that has a verified ground and meets
the following requirements:
Nominal Voltage .................... 110V, 115V, 120V
Cycle
..........................................................60 Hz
Phase
........................................... Single-Phase
Power Supply Circuit
......................... 20 Amps
Serious injury could occur if you connect
machine to power before completing setup
process. DO NOT connect to power until
instructed later in this manual.
-18-
Model G0958/G0959 (Mfd. Since 03/23)
Improper connection of the equipment-grounding
wire can result in a risk of electric shock. The
wire with green insulation (with or without yellow
stripes) is the equipment-grounding wire. If repair
or replacement of the power cord or plug is nec-
essary, do not connect the equipment-grounding
wire to a live (current carrying) terminal.
Check with a qualified electrician or service per-
sonnel if you do not understand these grounding
requirements, or if you are in doubt about whether
the tool is properly grounded. If you ever notice
that a cord or plug is damaged or worn, discon-
nect it from power, and immediately replace it with
a new one.
Extension Cords
We do not recommend using an extension cord
with this machine.
If you must use an extension
cord, only use it if absolutely necessary and only
on a temporary basis.
Extension cords cause voltage drop, which can
damage electrical components and shorten motor
life. Voltage drop increases as the extension cord
size gets longer and the gauge size gets smaller
(higher gauge numbers indicate smaller sizes).
Any extension cord used with this machine must
be in good condition and contain a ground wire
and matching plug/receptacle. Additionally, it must
meet the following size requirements:
Minimum Gauge Size ...........................12 AWG
Maximum Length (Shorter is Better).......50 ft.
Grounding & Plug Requirements

SHOCK HAZARD!
Two-prong outlets do not meet the grounding
requirements for this machine. Do not modify
or use an adapter on the plug provided—if
it will not fit the outlet, have a qualified
electrician install the proper outlet with a
verified ground.
This machine MUST be grounded. In the event
of certain malfunctions or breakdowns, grounding
reduces the risk of electric shock by providing a
path of least resistance for electric current.
This machine is equipped with a power cord that
has an equipment-grounding wire and a grounding
plug. Only insert plug into a matching receptacle
(outlet) that is properly installed and grounded in
accordance with all local codes and ordinances.
DO NOT modify the provided plug!

⁄2" Dust Port......................... 150 CFM
G0959 4" Dust Port............................. 400 CFM
Do not confuse this CFM recommendation with
the rating of the dust collector. To determine the
CFM at the dust port, you must consider these
variables: (1) CFM rating of the dust collector,
(2) hose type and length between the dust col-
lector and the machine, (3) number of branches
or wyes, and (4) amount of other open lines
throughout the system. Explaining how to cal-
culate these variables is beyond the scope of

Figure 16. Proper grain alignment with cutterhead
(jointer).
• DO NOT joint or surface plane stock that
contains large or loose knots. Injury to the
operator or damage to the workpiece can
occur if a knot becomes dislodged during the
cutting operation.
• DO NOT joint or surface plane against the
grain direction. Cutting against the grain
increases the likelihood of kickback, as well
as tear-out on the workpiece.
• Always joint with cupped side of workpiece
facing down. Otherwise workpiece could
rock during cut, increasing likelihood of kick-
back.
• Jointing and surface planing with the
grain produces a better finish and is
safer for the operator. Cutting with the grain
is described as feeding the stock so the grain
points down and toward you on the jointer (see
Figure 16) or away from you on the planer (see
Figure 17) as viewed on the edge of the stock.
Note: If the grain changes direction along the
edge of the board, decrease the cutting depth
and make additional passes.
Follow these rules when choosing stock for
jointing or planing:

• Scrape all glue off the workpiece before
jointing or planing. Glue deposits on the
workpiece, hard or soft, will gum up the
cutterhead and produce poor results.
• Remove foreign objects from the
workpiece. Make sure that any stock you
process with the jointer/planer is clean and
free of dirt, nails, staples, tiny rocks or any
other foreign objects that could damage the
cutterhead. These particles could also cause
a spark as they strike the cutterhead and cre-
ate a fire hazard.
IMPORTANT: Wood stacked on a concrete
or dirt surface can have small pieces of con-
crete or stone pressed into the surface.
• Make sure all stock is sufficiently dried
before jointing. Wood with a moisture con-
tent over 20% will cause unnecessary wear
on the cutters and poor cutting results. Excess
moisture can also hasten rust and corrosion.
• Only cut natural wood. This machine is
only designed for cutting natural wood stock.
Never use it to cut MDF, particle board, ply-
wood, laminates, drywall, backer board, met-
als, glass, stone, tile, products with lead-based
paint, or products that contain asbestos. Cutting
these may lead to injury or machine damage.

Cutting ProblemsPlaning Tips
• Inspect your lumber for twisting or cupping,
and surface one face on a jointer if necessary
before planing workpiece.
•
Scrape off all glue when planing glued-up
panels. Dried glue can quickly dull knives/
inserts.
•
DO NOT plane more than one piece at a time.
Never plane multiple pieces side by side.
•
Never remove more than the recommended
amount of material on each pass. Only
remove a small amount of material on each
pass when planing wide or dense stock.
•
Support the workpiece on both ends. Get
assistance from another person if you are
planing long lumber, or use roller stands to
support the workpiece.
•
Measure the workpiece thickness with cali-
pers to get exact results.
• Carefully inspect all stock to make sure it is
free of large knots or foreign objects that may
damage your knives/inserts, cause kickback,
or be ejected from the planer.
• When possible, plane equal amounts on
each side of the board to reduce the chance
of twisting or cupping.
•
Use the entire width of the planer to wear
knives/inserts evenly. With narrow workpiec-
es, alternate between far left, far right, and
the middle of the table. Your knives/inserts
will remain sharp much longer.
•
To avoid "chip marks," always plane WITH
the grain direction of the wood. Never plane
cross-grain or end-grain.
• Plane ONLY natural wood fiber. Do not plane
wood composites or other materials that
could break up in the planer and cause oper-
ator injury or damage to planer.
•
Always true cupped or warped stock on a
jointer before planing.
Below is a list of wood characteristics you may
encounter when planing. The following descrip-
tions of defects will give you some possible
answers to problems you may encounter while
planing different materials. Possible solutions fol-
low the descriptions.
Chipped Grain
Problem:
Usually a result of cutting against the
grain, planing lumber with knots or excessive
amount of cross grain, or using dull knives/inserts.
Note: Some amount of chipping is normal with
highly figured wood.
Solution: Decrease the depth of cut. Reduce the
feed rate. Inspect your lumber and determine if its
grain pattern is causing the problem. If the lumber
does not show substantial crossgrain, inspect
your knives/inserts.
Fuzzy Grain
Problem:
Usually caused by surfacing lumber
with too high of a moisture content. Sometimes
fuzzy grain is an unavoidable characteristic of
some woods, such as basswood. Fuzzy grain can
also be caused by dull knives/inserts.
Solution:
Check the lumber with a moisture
meter. If moisture is greater than 20%, sticker the
lumber and allow it to dry. Otherwise, inspect the
knife/insert condition.
Snipe
Problem
: Occurs when board ends have more
material removed than the rest of the board.
Usually caused when the workpiece is not prop-
erly supported as it goes through the machine. In
many cases, however, a small amount of snipe is
inevitable.
Solution:
Hold workpiece up slightly as it leaves
the outfeed end of the planer. The best way to
deal with snipe is by planing lumber longer than
your intended work length and then cutting off the
excess after planing is completed.

Wood Types
The species of wood, as well as its condition,
greatly affects the depth of cut the jointer/planer
can effectively take with each pass.
The chart in the figure below shows the Janka
Hardness Rating for a number of commonly
used species. The higher the number, the harder
the workpiece, and the less material should be
removed in any one pass for good results.
Note: The Janka Hardness Rating is expressed in
pounds of force required to embed a 0.444" steel
ball into the surface of the wood to a depth equal
to half the ball's diameter.

Pitch & Glue Build-Up
Problem: Glue and resin buildup on the rollers
and cutterhead will cause overheating by decreas-
ing cutting sharpness while increasing drag in the
feed mechanism. The result can include scorched
lumber, uneven insert marks, and chatter.
Solution: Clean the rollers and cutterhead.
Chip Marks or Indentations
Problem: Chip indentation or chip bruising is the
result of wood chips not being thrown away from
the cutterhead and out of the machine. Instead
they are carried around the cutterhead, deposited
on the wood surface and crushed by the outfeed
roller. Some of the causes of chip indentation are:
•
Wood chips/sawdust not being properly
expelled from cutterhead.
•
The type of lumber being planed. Certain
species have a tendency to chip bruise.
•
A high moisture content (over 20%) or sur-
face moisture.
•
Dull knives/inserts.
• Excessive depth of cut.
Solution:
•
Use a proper dust collection system.
• Lumber must be completely dry, preferably
kiln-dried (KD). Air-dried (AD) lumber must
be seasoned properly and have no surface
moisture. DO NOT surface partially-air-dried
(PAD) lumber.
•
Make sure knives/inserts are sharp.
• Reduce depth of cut.

Setting Jointer
Depth of Cut
The depth of cut on a jointer is the amount of mate-
rial removed from the bottom of the workpiece as
it passes over the cutterhead.
The depth of cut is set by adjusting the height of
the infeed table relative to the cutterhead inserts
at TDC (top dead center).
The depth-of-cut scale (see Figure 22) goes up to
5
⁄64", but the maximum depth of cut should never
exceed
1
⁄16".
Depth-of-Cut Scale
The depth of cut can be referenced directly
from the depth scale located on the front of the
machine (see Figure 22).
Note: Depth scale on G0959 can be calibrated or
"zeroed" if it is not correct. Refer to Calibrating
Jointer Depth-of-Cut Scale (G0959 Only) on
Page 48 for more information.
Adjusting Infeed Table Height
The infeed table adjustment knob (see Figure 21)
raises and lowers the infeed table. Turn the knob
clockwise to raise the table, and counterclockwise
to lower the table.

Previously Surface
Planed Face
Squaring stock involves four steps performed
in the order below:
1. Surface Plane on Jointer
—Concave face of
workpiece is surface planed flat with jointer.
2. Surface Plane on a Thickness Planer—
Opposite face of workpiece is surface planed
flat with a thickness planer.
Squaring stock means making it flat and paral-
lel along both length and width, and making the
length and width perpendicular to one another.
The purpose of squaring stock is to prepare it for
accurate cuts and construction later on.
A properly "squared up" workpiece is essential for
tasks such as accurate tablesaw cuts, glue-ups/
laminations, cutting accurate bevels on a band-
saw, and many other applications where one sur-
face of a workpiece is used to reference another.

Bevel cuts (see example Figures below) can be
made by setting the fence at the desired angle
and feeding the workpiece firmly along the fence
face, with the bottom inside corner firmly against
the table. The cutting process typically requires
multiple passes or cuts to bevel the entire edge
of a workpiece.
To bevel cut on jointer:
1. Inspect stock to ensure it is safe and suitable
for the operation (see Stock Inspection &
Requirements section).
2.
Surface plane workpiece (see Surface
Planing on Jointer section).
3.

Set infeed table height to cutting depth
desired for each pass.
CAUTION: Do not exceed cutting depth
of
1
⁄16" per pass.
5.
Set fence tilt to desired angle of cut.
6. Place workpiece against fence and infeed
table with concave side face down.
7.
Start jointer.
8. With a push block in your leading hand,
press workpiece against table and fence
with firm pressure, and feed workpiece over
cutterhead with a push block in your trailing
hand.
CAUTION: When your leading hand gets
within 4" of the cutterhead, lift it up and over
cutterhead, and place push block on portion
of the workpiece once it is 4" past cutterhead.
Now, focus your pressure on outfeed end
of the workpiece while feeding, and repeat
same action with your trailing hand when it
gets within 4" of cutterhead. To help keep
your hands safe, DO NOT let them get closer
than 4" from moving cutterhead at any time
during operation!

Jointer/Planer
Conversion
After completing the Assembly section on Page
21, the machine is set up for jointer operations.
To prepare the machine for planer operations,
the following conversion must be performed: The
dust port housing must be moved from the bottom
of the outfeed table to the top of the table, and
the cutterhead guard lock-out must be engaged
to prevent the guard from springing into position
over the cutterhead during planer operations.
To perform jointer/planer conversion:
1.
DISCONNECT MACHINE FROM POWER!
2.
G0958 Only: Move fence all the way right, tilt
to 45° outward, and lock in position.
G0959 Only: Remove fence from support brack-
et, tilt bracket to 45° outward, and lock in position.
3.
Release interlock keys on both sides of
outfeed table, and remove dust port housing.
Carbide inserts are very sharp and can
quickly cut hands. ALWAYS use caution
when working around these parts to reduce
risk of personal injury.

The depth of cut on a planer means the amount
of material that is removed from the top of the
workpiece as it passes underneath the cutterhead.
The depth of cut is set by adjusting the distance of
the table beneath the cutterhead. This distance is
the thickness of the workpiece minus the depth of
cut. The planing depth of cut is controlled by using
the planer table height crank on the right side of
the machine (see Figure 29). Rotating the crank
clockwise raises the table.
Figure 30. Planer thickness scale components.
Scale
Arrow
Although the correct depth of cut varies accord-
ing to wood hardness and workpiece width, we
recommend the maximum depth of cut (per pass)
be no more than
3
⁄64". A series of light cuts will
give better end results and put less stress on the
planer than trying to take off too much material in
a single pass.
The thickness scale functions as a general guide
only, and is not intended for low-tolerance, preci-
sion results. A small amount of backlash may
be present with the planer table height crank
after switching height directions. Switching height
direction may cause slightly less than
1
⁄16" back-
lash during the first crank turn. As the crank is
turned more rotations in the same direction, back-
lash will not be a factor.

Feeding Workpiece
The feed rate on this planer is automatically set
at 22 FPM. Infeed and outfeed rollers move the
workpiece through the planer while keeping it
firmly against the table and providing a consistent
rate of movement.
To feed workpiece into planer:
1.
Place first 3"–4" of workpiece flat on planer
table, then raise planer table until workpiece
just touches depth bar on bottom of jointer
outfeed table (see Figures 31–32).
Figure 31. Basic planing operation setup.
Jointer
Outfeed Table
2. Rotate planer table height crank
3
⁄4 turn coun-
terclockwise to lower table approximately
3
⁄32". This will set depth of cut to
1
⁄32". Remove
workpiece from planer.
Note: Any time you switch directions with
planer table height crank, there will be a small
amount of backlash—so the first full turn of
the crank after switching directions will be
slightly less than
1
⁄8". However, as long as you
move crank in same direction during opera-
tion, backlash will not be a factor.
3.
Turn planer ON.
4.
Place workpiece on planer table with side to
be planed facing up toward cutterhead.
Note: Boards more than 24" long should be
supported on both sides of planer.
5.
Feed workpiece into front of planer (beneath
jointer outfeed table), making sure not to
stand directly in front of or behind workpiece
to reduce risk of kickback injury.
— If cut is too deep and bogs down planer,
turn planer OFF immediately and allow it
to stop. Lower table, remove workpiece,
reduce depth of cut, then repeat Step 5.
Note: Infeed and outfeed rollers will automat-
ically pull workpiece through planer during
operation. Do not push or pull on workpiece
once feed rollers have engaged it.
6.
Once workpiece is clear of outfeed roller,
measure workpiece thickness. If further plan-
ing is needed, raise table another
1
⁄4 turn (
1
⁄32")
of height crank, and repeat cutting operation.
7.
Continue process described above until
desired workpiece thickness is reached.
Thickness scale shows approximate thick-
ness of workpiece after it has been cut.
Use this indicator to judge when thickness
is approximately correct. For more precise
applications, measure workpiece thickness
with calipers during cutting operation.

Carbide inserts are very sharp and can
quickly cut hands. ALWAYS use caution and
heavy leather gloves when handling these
parts to reduce risk of personal injury.
4. Remove any sawdust or debris from head of
insert, Torx screw, and surrounding area.
5.
Remove Torx screw and insert, then clean all
dust and debris from both parts and pocket
they were removed from.
Note: Proper cleaning of insert, Torx screw,
and cutterhead pocket is critical to achiev-
ing a smooth finish. Dirt or dust trapped
between insert and cutterhead will raise
insert, and make marks on your workpiece
when jointing/planing.
Tip: Use low-pressure compressed air or
a vacuum nozzle to clean out cutterhead
pocket.
6.
Rotate insert 90° and install so that a fresh
cutting edge faces outward (see Figure 33).
— When all four insert cutting edges have
been used, replace insert with a new one.
Always position insert reference dot in
same position when installing a new insert
to aid in rotational sequencing.
7.
Lubricate Torx screw threads with a very
small amount of light machine oil, wipe
excess off, and torque screw to 50–55 inch/
pounds.
Note: If too much oil is applied to threads,
excess oil will attempt to squeeze out of
threaded hole and raise insert during installa-
tion, bringing it out of height alignment.
8.
When finished, re-install dust port housing
and release lock-out so guard will swing back
over cutterhead.
3.
Put on heavy leather gloves to protect your
fingers and hands.

SECTION 6: MAINTENANCE
For optimum performance from your machine,
follow this maintenance schedule and refer to any
specific instructions given in this section.
Ongoing
To maintain a low risk of injury and proper
machine operation, if you ever observe any of the
items below, shut down the machine immediately
and fix the problem before continuing operations:
• Loose mounting bolts.
• Damaged inserts.
•
Worn or damaged wires.
•
Any other unsafe condition.
Monthly Check
• Clean chains and sprockets of dust, wood
chips, and old grease.
• Lightly coat chains and sprockets with NLGI#2
grease (see Page 39).
• Lubricate table height leadscrews with spray
lubricant (see Page 39).
• Check belt for tension, damage, or wear (see
Page 46). Also, ensure belt is clean and free
of oil or grease that could cause it to slip.
• Clean builtup sawdust and chips underneath
machine and around motor.
Schedule
To reduce risk of shock or
accidental startup, always
disconnect machine from
power before adjustments,
maintenance, or service.
Cleaning the Model G0958/G0959 is relatively
easy. Vacuum excess wood chips and sawdust,
and wipe off the remaining dust with a dry cloth.
If any resin has built up, use a resin-dissolving
cleaner to remove it.
Cleaning &
Protecting
Lubrication
Since all bearings are sealed and permanently
lubricated, simply leave them alone until they
need to be replaced. DO NOT lubricate them.
It is essential to clean components before lubri-
cating them because dust and chips build up on
lubricated components and make them hard to
move. Simply adding more grease to them will not
yield smooth moving components.
Clean the components below with mineral spirits
or other oil/grease solvent cleaner and shop rags.

Tensioning/
Replacing V-Belts
The Model G0958/G0959 uses two V-belts. The
drive belt transfers power from the motor to the
cutterhead, and the feed belt transfers power
from the cutterhead to the infeed and outfeed roll-
ers. To ensure efficient transfer of power to these
systems, make sure the belts are always properly
tensioned and in good condition.
If the belts are worn, cracked, or damaged,
replace them immediately.
V-belts and pulleys will be hot after opera-
tion. Allow them to cool before handling.
To replace feed belt:
1.
DISCONNECT MACHINE FROM POWER!
2. Remove front cover.
3. Roll belt off pulleys and install new belt (see
Figure 45).
Note: The elasticity of the feed belt makes it
possible to easily stretch it over the pulleys.
Replacing Feed Belt
Due to the design of the machine, the feed belt
can be replaced, but there is not a mechanism for
tensioning the belt. When installed correctly, the
belt will be properly tensioned.
4.
When belt is fully on both pulleys, rotate it
several times to make sure belt ribs are fully
seated in pulley grooves.
5.
Re-install front cover.

The infeed tables on the Model G0958/G0959
include positive stops that can be adjusted to
allow the operator to quickly adjust table height
between cuts.
We recommend setting the minimum depth of cut
to
1
⁄32", and the maximum depth of cut to
1
⁄16" for
most operations.
Do not exceed
1
⁄16" cut per pass on this

Checking/Replacing
Motor Brushes
The motor on the G0958/G0959 is equipped with
two long-life carbon brushes—one on each side
of the motor. The brush life is affected by motor
loads and usage. Worn brushes will result in inter-
mittent operation and difficulty starting the motor.
If either brush is worn down to
1
⁄4" (6mm) or less,
replace both brushes as a set.

To check/replace motor brushes:
1. DISCONNECT MACHINE FROM POWER!
2.
Gently lay machine on its back to expose
motor beneath machine base.
3.
Unscrew plastic brush covers, and remove
motor brush assemblies (see Figure 60).
Note: As you remove brush assembly, make
note of carbon tip orientation. If found accept-
able, re-install in same way.
4. Measure length of carbon tip. If carbon tip is
worn down to
1

table height chain beneath machine base.
Do not let chain fall off sprockets. It can be
very difficult to return chain to its proper
location on sprockets without changing
table adjustments.

push idler sprocket against chain with moder-
ate pressure. Maintain pressure on sprocket
and tighten cap screw.

Wiring Safety Instructions
SHOCK HAZARD. Working on wiring that is con-
nected to a power source is extremely dangerous.
Touching electrified parts will result in personal
injury including but not limited to severe burns,
electrocution, or death. Disconnect the power
from the machine before servicing electrical com-
ponents!
MODIFICATIONS. Modifying the wiring beyond
what is shown in the diagram may lead to unpre-
dictable results, including serious injury or fire.
This includes the installation of unapproved after-
market parts.
WIRE CONNECTIONS. All connections must
be tight to prevent wires from loosening during
machine operation. Double-check all wires dis-
connected or connected during any wiring task to
ensure tight connections.
CIRCUIT REQUIREMENTS. You MUST follow
the requirements at the beginning of this manual
when connecting your machine to a power source.
WIRE/COMPONENT DAMAGE. Damaged wires
or components increase the risk of serious per-
sonal injury, fire, or machine damage. If you notice
that any wires or components are damaged while
performing a wiring task, replace those wires or
components.
MOTOR WIRING. The motor wiring shown in
these diagrams is current at the time of printing
but may not match your machine. If you find this
to be the case, use the wiring diagram inside the
motor junction box.
CAPACITORS/INVERTERS. Some capacitors
and power inverters store an electrical charge for
up to 10 minutes after being disconnected from
the power source. To reduce the risk of being
shocked, wait at least this long before working on
capacitors.
EXPERIENCING DIFFICULTIES. If you are expe-
riencing difficulties understanding the information
included in this section, contact our Technical
Support at (570) 546-9663.
The photos and diagrams
included in this section are
best viewed in color. You
can view these pages in
color at www.grizzly.com.
These pages are current at the time of printing. However, in the spirit of improvement, we may make chang-
es to the electrical systems of future machines. Compare the manufacture date of your machine to the one
stated in this manual, and study this section carefully.
If there are differences between your machine and what is shown in this section, call Technical Support at
(570) 546-9663 for assistance BEFORE making any changes to the wiring on your machine. An updated
wiring diagram may be available. Note: Please gather the serial
number and manufacture date of your
machine before calling. This information can be found on the main machine label.
