CHANGING THE BLADE
Use only cross-cutting saw blades.
When using carbide-tipped blades, do
not use blades with deep gullets as they can deflect
and contact the guard.
Use only 10" diameter saw blades that
are rated for 5200 RPM or higher and have 5/8" diameter
arbor holes.
Disconnect the machine from the power
source!
1. Remove the screw (A) Fig. 44 and rotate the cover
(B) to the rear (Fig. 45).
2. To remove the saw blade, insert the supplied hex
wrench (C) Fig. 46 into the hex hole located on the
rear end of the motor shaft to keep the shaft from
turning.
3. Use a wrench (G) Fig. 47 to loosen arbor screw (E)
by turning it clockwise.
4. Remove arbor screw (E) Fig. 47, outside blade
flange (F), and saw blade from saw arbor.
5. Attach the new saw blade. MAKE SURE THAT
THE SAW TEETH ARE POINTING DOWN AT THE
FRONT. Re-attach the outside blade flange (F) Fig.
47, and the arbor screw (E) by turning it counter-
clockwise using the wrench (G) Fig. 47. At the same
time, use the hex wrench (C) Fig. 46 to keep the
arbor from turning.
6. Replace screw and cover that was rotated to the
rear in STEP 1.
Remove the wrenches (C) FIG. 46
AND (G) FIG. 47 before starting the machine.
