hand side, it is not necessary to remove the wing. The

extension table can extend past the rails and tube.

9. Place table assembly (L) Fig. 12, in position between the two

rails, as shown. Make sure end of table is flush against saw table

(M). Using a straight edge make sure table (L) is in the same plane

and level with saw table (M). Lightly tap up or down and adjust leg

leveling screws. When you are certain table (L) is level and in the

same plane with saw table (M) tighten bar clamp (P) to hold

everything in position. Then drill 1/4” holes through the front and

rear of the extension table using holes (Q) provided in rails as a

template. NOTE: Number of holes (Q) in the front and rear rails will

vary depending on the length of the rails you purchased.

10. After the holes have been drilled in the edge of the front and rear

extension table board, fasten both front and rear rail to table using

the 1/4-20 x 1-1/2” flat head Phillips screws, 1-1/4” O.D. flat

washers and hex nuts (R).

11. Lay the guide tube (B) Fig. 14, on the saw table as shown, and

line up the threaded holes (S) on the bottom of guide tube with the

through holes (T) on the front rail. NOTE: The guide tube should

extend past the rail 6” on each end.
