MANUAL VALVE COLD PLANERS
The manual valve (non-electro-hydraulic) cold planers
utilize a three-function valve stack to control both direc-
tion and function. Figure 5 shows the position and func-
tion of the three levers.

Do not raise or roll back the lift arms when the
valve arm is lowered into the cab. Failure to follow
these instructions could result in serious injury.
HYDRAULIC DEPTH CONTROL
To operate the hydraulic depth control, set the options
toggle switch to “depth” and actuate the auxiliary circuit
to achieve the desired depth.
HYDRAULIC TILT
To operate the hydraulic tilt, set the options toggle
switch located at the operator’s control panel to “tilt”,
and actuate the auxiliary circuit.
SIDESHIFT ADJUSTMENT
1. Raise the planer 6" to 8" off the ground.
2. Engage the parking brake on the skid steer.
3. Stop the engine.
4. The planer can be shifted side-to-side using the
sideshift function. The two sideshift hoses when
connected to the auxiliary hydraulics of the skid
steer, provide hydraulic power necessary for
sideshift operation. By actuating the auxiliary
circuit, the planer will shift on the sideshift rod.
PLANER OPERATION
■
Never open the top cover used for drum access
during operation. The two cover latches (see parts
section) should be checked to make sure they are
securely fastened before beginning operation.
To operate the cold planer, lower the valve arm into the
cab.
NOTICE
■
When the valve arm is lowered into the cab, do
not raise the lift arms excessively. The valve may
interfere with the cab causing damage to the skid
steer or the cold planer.
Activate the auxiliary hydraulics. Be sure the drum is
rotating counter-clockwise direction if viewed from the
motor side of the cold planer.
When engaging the hydraulic power to the attachment,
the drum should not be in contact with the surface to be
