CONTROLLER INFORMATION
Do not attempt to disassemble the Controller.
The Controller is available only as a unit and is guaranteed

Prior to assembly, carefully inspect the Controller
Assembly for nicks, gouges and dents. Replace it with a
new Controller Assembly if necessary. Test the free speed
before applying a blade.
SAW BLADES
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
to remove the Bolt.
2. Using a wrench on the flats of the Bolt, unscrew and
remove the Saw Blade Flange Bolt.
3. Remove the Saw Blade Flange from the Saw Blade.
4. Retract the Swing Guard and withdraw the Blade
through the Base.
Installation
1. Retract the Swing Guard and insert the Blade up
through the Base, 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, 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
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.
2. Grasp the Handle with one hand and hold the Base
with the other.
3. Lift the motor and Guard 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.
4. Securely tighten the Depth Gauge Knob.
Setting the Angle of Cut
1. Loosen the two Tilt Sector Thumb Screws.
2. Tilt the motor and Guard on the Base until the desired
setting is obtained as shown on the scale scribed on the
edge of the Front Tilt Sector.
3. Tighten the two Tilt Sector Thumb Screws securely.
Sighting and Sawing
1. Open the throttle wide by squeezing the Throttle Lever
in the Handle.
2. 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.
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.)
