Hydraulic Ball Valve (Hydraulic Model)
WARNING
• DO NOT disconnect hydraulic hoses from the
hydraulic motor saw when the saw or the
hydraulic power unit is running.
• Always place a piece of cardboard
or paper up against hydraulic
components, or use a leak
detection fluid to check for
hydraulic fluid leaks. Keep all body parts away
from leaks and/or areas that may eject
hydraulic fluid. Pressurized hydraulic fluid can
penetrate the skin, causing serious injuries.
Seek medical attention immediately!
The hydraulic ball valve assembly is on the frame’s left
side and can be moved to the frame’s right side if
preferred. Note: When moving the ball valve to the right
side of the saw, the water valve must be removed and
secured to the left side.
Disconnecting the Hydraulic Ball Valve
Note: Place an oil drain tray underneath any hose
connection points for possible oil drainage.
1. Disconnect the pipe adapter from the steel pressure
line fitting. DO NOT disconnect the pipe adapter
from the quick disconnect.
2. Disconnect the pipe adapter from the steel return
line fitting. DO NOT disconnect the pipe adapter
from the quick disconnect.
3. Disconnect the pressure line hose from the pipe tee
at the top of the hydraulic ball valve.
4. Disconnect the return line hose from the pipe tee at
the bottom of the hydraulic ball valve.
5. Remove the U-bolts, valve assembly, and shim plate
from the frame upright.
Connecting the Hydraulic Ball Valve
1. Rotate the pressure line pipe tee 180°.
2. Rotate the return line pipe tee 180°.
3. Secure the shim plate and valve assembly to the
opposite side of the saw using the U-bolts and nuts.
4. Fit the steel pressure line into the upper plug hole
below the handlebar shaft, and fit the steel return
line into the lower plug hole below the handlebar
shaft.
5. Connect the pressure line hose to the pipe tee at the
top of the valve.
6. Connect the return line hose to the pipe tee at the
bottom of the valve.
7. Connect the pipe adapter for the pressure line to the
steel pressure line fitting.
8. Connect the pipe adapter for the return line to the
steel return line fitting.
Speed Control Lever
When the speed control lever (self-propelled model) is
out of sync with the saw; for example, if the saw moves
forward when the lever is at Neutral adjustments are
needed.
Adjusting the Speed Control Lever
1. Start the engine and engage the transmission.
2. Adjust the speed control lever until the saw stops
moving completely. This is the current neutral
position. DO NOT move the speed control lever any
further.
3. Disengage the transmission and turn off the engine.
4. Loosen the pivot pin setscrew near the transmission.
