CHANGING THE SAW BLADE

DISCONNECT MACHINE FROM POWER

SOURCE.

1.NOTE: Two wrenches are supplied with the saw for changing the saw blade; a box end wrench (A) Fig. 58 and a 8mm hex wrench (B).

2.Remove table insert (D) and raise saw blade to its maximum height.

3.To remove blade, place the hex wrench (B) Fig. 58, in the hex hole in the arbor to keep the arbor from turning, and use box end wrench (A) to turn the arbor nut (C) toward the front of the saw. Remove arbor nut, blade flange and saw blade.

4.Assemble the new blade, making certain the teeth point down at the front of the saw table and assemble outside blade flange and arbor nut. With hex wrench (B) Fig. 58, inserted in the hex hole on the arbor to keep it from turning, tighten arbor nut by turning box end wrench (A) toward the rear of the saw.

5.Replace table insert. IMPORTANT: When installing the table insert, make certain to hold on to the blade guard.

NOTE: Use only 10" saw blades with 5/8" arbor

holes, rated for at least 4000 RPM.

REPLACING BELTS AND

ADJUSTING BELT TENSION

DISCONNECT MACHINE FROM POWER SOURCE.

1.Remove motor cover to gain access to the motor.

2.Put blade at 90 degrees. Place a block of wood (C) Fig. 59, in between the motor and saw cabinet as shown and lower the arbor until the motor contacts the wood.

4.Loosen two bolts on the motor mounting plate, one of which is shown at (D) Fig. 59 and continue to lower the saw arbor until all tension is removed from the three belts (E). Tighten bolt (D).

5.Raise the saw arbor slightly to remove block of wood (C).

6Remove the arbor bracket cover (G) Fig 59A. Three screws hold the cover in place at (H). To get to the top screw, tilt and then raise the arbor. Return arbor to previous position once cover is off.

7.Remove the belts (E) Fig. 59A, one at a time from the motor pulley and then the arbor pulley (F) Fig. 60. It will be necessary to twist the belt 90 degrees so its thinnest profile slides through the gap between the arbor bracket

(I)Fig. 60 and the cast iron arm casting (J) Fig. 60.

8.Assemble the three new belts, one at a time in the grooves of the arbor pulley (F), and onto the motor pulley.

9.Replace the arbor bracket cover (G) Fig. 59A.

10.When the new belts are assembled, loosen screw (D) Fig. 59 while holding the motor up. Carefully lower the motor onto the belts. Tighten screw (D).

11.Check belt tension. Correct belt tension is when there is approximately 1/4" deflection in the center span of the pulleys, using light finger pressure. If more tension is needed, push down on the motor. Then tighten screw

(D).Once you have proper tension, be sure to tighten the screw (not shown) on the opposite side of the motor mounting plate.
