Installation
1. Retract the Swing Guard (75) and insert the Blade (93)
up through the Base (63), making sure the teeth on the
Blade 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 (40), aligning the two
holes in the Blade with the corresponding holes in the
flange on the Arbor.
3. Locate the Saw Blade Flange (91) on the Arbor so the
pins enter the holes in the Blade and Arbor Flange.
In the following step, the Saw Blade Flange Bolt (92)
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
rotating. Using the a wrench on the flats of the Bolt,
tighten the Bolt between 70 and 75 ft–lb (95.0 and
101.7 Nm) torque.
Setting the Depth of Cut
1. Loosen the Depth Gauge Knob (66).
2. Grasp the Handle (47) with one hand and hold the Base
(63) with the other.

3.
Lift the motor and Guard (64) from the Base until the
distance from the bottom face of the Base and the
lowest point on the Blade is equal to the depth desired.

Securely tighten the Depth Gauge Knob.
Setting the Angle of Cut
1.
Loosen the two Tilt Sector Thumb Screws (87).
2.
Tilt the motor and Guard (64) on the Base (63) until
the desired setting is obtained as shown on the scale
scribed on the edge of the Front Tilt Sector (81).
3.
Tighten the two Tilt Sector Thumb Screws securely.
Sighting and Sawing
1.
Open the throttle wide by squeezing the Throttle Lever
(48) in the Handle (47).
2.
Align the mark to be followed with the pointer on the
Yoke Pivot (88), and push the Saw forward. The Swing
Guard (75) will retract into the Stationary Guard (64)
as the Blade (93) 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.
Abrasive Blades
For cutting ferrous and nonferrous materials, Abrasive
Blades are recommended. These Blades require the use
of an Inner Blade Flange, Outer Blade Flange and a
longer Blade Flange Bolt. (See parts list)
