Operation

Stopping The Machine

DUE TO HIGH SPEED LOW-FRICTION ROTATION,
THE CUTTING WHEEL MAY CONTINUE TO ROTATE
UNNOTICED, EVEN AFTER THE ON/OFF SWITCH
HAS BEEN FLIPPED OFF, AND EVEN AFTER THE
ENGINE HAS STOPPED. BE SURE TO BRING
CUTTING WHEEL ROTATION TO A COMPLETE STOP
BEFORE MOVING THE MACHINE OR LEAVING THE
CONTROLS!
1. When stopping the machine after normal operation,
lower the engine speed to SLOW, and cycle each of
the hydraulic controls slowly for about 30 seconds each
to help the hydraulic com po nents to cool slowly.
2. Flip the cutting wheel ON/OFF Switch down to the OFF
position, stopping the cutting wheel rotation.
3. Stop the cutting wheel rotation quickly by gently lowering
the cutting wheel into the soil.
4. Reduce the engine speed.

Engine Stopping

1. Reduce the engine speed to IDLE.
2. Turn the engine start switch to the OFF position to stop
the engine. Remove the engine start key.

Testing The Brake

This machine is required to have a daily inspection of the
ground-drive brake. This check should be done by the operator
every day, before using the machine.
The ground-drive brake on this machine is a spring-activated,
hydraulically-released unit. This means that anytime the unit is
not being moved with hydraulic pressure, the spring-applied
brake should engage. The machine should never visibly
"creep" when it is not being moved.
The machine can be tested on any slope, but the simplest
inspection can be done when unloading or loading the
machine onto its trailer, or into a pickup truck. When the
drive wheels are on the ramps, bring the machine to a halt,
and observe the drive wheels. The wheels should not turn
at all. No "creep" should be evident.
If the machine can be observed to be creeping down the
ramp, check the following items:
• Both drive wheels are engaged.
Correct all of these items and retest the machine. If the
machine still creeps, then the spring-activated brake has been
32
damaged. The drive motor must be replaced. Failure to keep
the ground-drive brake in working condition can result in a
machine moving unexpectedly, causing injury or death. The
machine must be taken out of service until the ground-drive
motor is repaired or replaced.
The machine is always to be parked with the drive
wheels engaged, and the drive wheels chocked.

Parking The Machine

Park on a level surface if possible. If it is necessary to park on
a grade, block the tracks securely and set the parking brake.
Do not park sideways on a hill, side-sliding could occur.
• Lower the engine speed control slightly to reduce
engine rpm.
• Center the cutter boom, using the joystick.
• Turn off the cutting wheel by moving the control lever
to the off position
• Center the Left Joystick to stop the machine
• Press the parking brake button on the keypad
• Lower the attachment slowly with the Right Joystick until
the cutting wheel rests on the ground.
