MAINTENANCE

CHANGING THE SAW BLADE

DISCONNECT MACHINE FROM POWER SOURCE!

NOTE: Two wrenches are supplied with the saw for

changing the saw blade: a box-end wrench and open- end wrench.

1.	Remove table insert (C) Fig. 53, and raise saw blade
	to its maximum height.
2.	Place the open end wrench (B) Fig. 53 on the flats of
				B
	the saw arbor to keep the arbor from turning, and
		C
	use wrench (A), to turn the arbor nut toward the front
	of the saw. Remove arbor nut, blade flange, and saw
	blade.

3.	Attach the new blade, making certain the teeth point	Fig. 69
	down at the front of the saw table, and assemble
	outside blade flange and arbor nut. With wrench (B)
	Fig. 53, on the flats of the arbor to keep it from turning, tighten arbor nut by turning wrench (A) Fig. 54
	counterclockwise 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

1.Open the motor cover door to gain access to the motor.

2.Place a block of wood (C) Fig. 70 between the motor and the saw cabinet.

NOTE: You may have to raise the saw arbor to insert the wooden block. Lower the saw arbor until the motor contacts the wood.

3.Loosen the bolt (D) Fig. 70 and continue to lower the saw arbor until all tension is removed from the belts (E). Tighten the bolt (D).

4.Raise the saw arbor slightly and remove the block of wood (C) Fig. 70.

5.Lower the saw arbor. Remove the belts (E) Fig. 71, one at a time from the motor pulley.

6.Remove the belts (E) Fig. 71 one at a time from the arbor pulley (F).

7.Install the three new belts, one at a time in the grooves of the arbor pulley (F) Fig. 71, and on the motor pulley.

8.When the new belts are installed, loosen the screw (D) Fig. 70, and carefully let the motor rest on the belts.

9.The correct belt tension shows approximately 1/4" deflection in the center span of the pulleys, using light finger pressure.

10.Tighten the screw (D) Fig. 70.
