Removal
1.
Insert a screwdriver into the 3/8” (9.5 mm) sprag hole
of the Saw Blade to keep the Arbor from rotating.
In the following step, the Saw Blade Flange Bolt
has a left–hand thread. Rotate the wrench clockwise

point in the direction in which the Blade will rotate
(clockwise when facing the blade side of the tool).
2.
Slip the Blade over the Arbor, aligning the two holes in
the Blade with the corresponding holes in the flange on
the Arbor.
3.
Locate the Saw Blade Flange on the Arbor so the pins
enter the holes in the Blade and Arbor Flange.
In the following step, the Saw Blade Flange Bolt has a
left–hand thread. Rotate the wrench counterclockwise
to install the Bolt.
4.
Screw the Saw Blade Flange Bolt into the end of the
Blade Arbor.
5.
Use a screwdriver inserted into the 3/8” (9.5 mm)
sprag hole in the Saw Blade to keep the Arbor from

Loosen the Depth Gauge Knob.
2.
Grasp the Handle with one hand and hold the Base

Open the throttle wide by squeezing the Throttle Lever
in the Handle.

Align the mark to be followed with the pointer on the
Yoke Pivot, and push the Saw forward. The Swing
Guard will retract into the Stationary Guard as the
Blade enters the material to be cut.
3.
When the cut is finished, release the Throttle Lever and
lift the Saw from the work. The Swing Guard will
immediately swing out of the Stationary Guard to
cover the Saw Blade.
