NOTICE:
TO RELEASE THE LOCK, THE TRUCK PTO WILL HAVE TO
BE ENGAGED AND THE LIFT ARM RAISED SLIGHTLY TO
RELIEVE THE STRAIN ON THE LATCH. ADDITIONALLY, THE
LOCKING ARM MUST BE MANUALLY RAISED FROM THE LIFT
ARM AND THE HYDRAULIC LATCH CLOSED AND LOCKED
BEFORE OPERATING THE LIFT ARM AND CUTTER.
Lift Arm Slide Track
The lift arm slide track & trolley mounting system
enables the operator to move the arm and cutter
to either side of the truck or any place in between.
The arm is mounted to a special chassis plate that
rides on heavy duty rollers and slide tracks on
the rear of the chassis. A hydraulic motor on the
arm controlled by the joystick or the LEFT/RIGHT
buttons on the digital control panel moves the lift
arm and secures it in the desired position.
Refer to the Operation section for instructions on
operating the lift arm slide track system.
WARNING
THE CUTTER IS HEAVY AND WILL CAUSE THE TRUCK
CHASSIS TO BE OFF BALANCE IF IT IS NOT CENTERED
BEFORE TRAVELING ON THE HIGHWAY. THIS COULD
CAUSE HANDLING PROBLEMS THAT COULD RESULT IN
AN ACCIDENT.
ALWAYS MAKE SURE THE CUTTING UNIT IS MOVED TO THE
CENTER OF THE TRUCK CHASSIS FOR PROPER BALANCE
BEFORE TRAVELING ON THE HIGHWAY.
Articulation Hinge
The cutter chassis is connected to the arm by
an articulating hinge that allows the chassis to
articulate right or left as it follows the contour of
irregular pavement.
Two pins, one on each side of the hinge are in-
serted to prevent the cutter from articulating
during travel. The pins are normally left in place
when cutting pavement that is relatively flat and
consistent. When cutting pavement with ledges or
other inconsistencies that require additional cutter
articulation, the pins can be removed.
To remove the pins, make sure the cutter is raised
to take the load of the pins. Pull each pin out
and allow them to hang on the tether. Install the
