Installation And Removal Of The Blade
Disconnect plug from power source
before performing any assembly,
adjustment or repair to avoid possible injury.
1. Loosen rear cover plate screw one full turn. Do
not completely remove screw.
2. Loosen front cover plate screw (approximately three full
turns) until it clears the tab on the cover plate; but do
not completely remove screw. Rotate coverplate
counter-clockwise, exposing arbor bolt blade area.
3. Rotate the guard by hand to clear the blade. Let go of
guard. Plastic will be held out of way by front screw.
4. Press and hold the arbor lock. The blade may
need to be rotated for the arbor lock to catch.
Use the blade wrench to remove the blade bolt
by turning wrench clockwise. NOTE: The blade
bolt has a left hand thread.

To install the 10" blade, fit blade between the
chip deflectors and onto arbor shaft (Figure 3).

blade matches the clockwise rotation arrow on
the lower guard.
