Figure 8: Speed Control Lever and Control Grip
Speed Control Lever
The speed control lever moves the saw forward and
backward. The maximum speed the saw will move at full
throttle is 200 ft/min. Push in the emergency stop button
to immediately stop the engine and saw movement if
necessary when operating the saw. Note: The engine
must be running to move the saw using the speed
control lever.
1. Slowly push the lever forward to move the saw
forward and release when at the desired traveling
speed.
2. Slowly pull the lever backward to move the saw
backward and release when at the desired traveling
speed.
3. Place the lever at Neutral to stop the saw. DO NOT
assume at any time that Neutral will act as a brake.
Note: Always start the engine with the speed control
lever at Neutral.
Control Grip
The control grip pushbuttons raise and lower the saw
(works with engine off).
1. Press the left pushbutton to raise the saw and
release to stop. Note: Raise the blade when
maneuvering the saw to provide proper clearance
between the blade and the ground.
2. Press the right pushbutton to lower the saw and
release to stop.
Blade Lowering Speed
Turn the Blade Lowering Speed valve counterclockwise
to increase the blade’s lowering speed and clockwise to
decrease the blade’s lowering speed.

Water Supply
The water supply cools the blade and minimizes dust
when cutting. Note: Always test the water supply for
adequate pressure and flow prior to cutting.
Using the Water Supply
1. Connect the water source hose to the hose fitting on
the frame upright.
2. Connect the water supply hose to the blade guard.
Note: Disconnect and reconnect this hose when
moving the blade guard to the opposite side of the
saw.

3. Push
the Water lever up to increase the water flow,
or push the Water lever down to decrease the water
flow. Note: Activate the water supply just before
cutting in order to save water.
4. Turn off the Water lever and disconnect the water
source hose from the saw when finished. Disconnect
the water supply hose from the blade guard if
necessary.
