CHANGING THE BLADE

Use only cross-cutting saw blades.

A

When using carbide-tipped blades, do not use blades with deep gullets as they can deflect and contact the guard.

B

Use only 10" diameter saw blades which are rated for 5200 rpm or higher and have 5/8" diameter arbor holes.

2.To remove the saw blade, insert the hex wrench (C) Fig. 43 into the hex hole located on the rear end of the motor shaft to keep the shaft from turning.

3.Use a wrench (D) Fig. 44 to loosen the arbor screw (E) by

turning it clockwise.		Fig. 43
4. Remove the arbor screw (E) Fig. 44, the outside blade
flange (B), and the saw blade from the saw arbor.
5. Attach the new saw blade making certain that the teeth of
the saw blade are pointing down (Fig. 44). Place the
outside blade flange (F) on the arbor, and attach the arbor
screw (E) by turning it counter-clockwise using the wrench
(D). At the same time, use the hex wrench (C) Fig. 43 to			E
keep the arbor from turning.					T

					H
	Remove wrenches (C) Fig. 43 and (D) Fig. 44
	before starting machine.

	The cover must be returned to its original
	position and the screw tightened before
	activating the saw. Failure to do so may
	allow the guard to contact the spinning saw	Fig. 44
	blade resulting in damage to the saw and
	severe personal injury.

BRUSH INSPECTION AND REPLACEMENT
