2.7 lift arm & locking mechanism
Lift Arm And Cylinders
The cutter lift arm assembly is mounted to a slide
track on the rear of the chassis. A hydraulic motor
and drive gear mounted to the front of the arm
moves the arm right and left on the slide track.
All functions of the cutter and lift arm are con-
trolled by the joystick and switches in the digital
controller or remote controls.
The accessory hydraulic system provides the
power for all functions of the arm. It is activated
by the TRUCK PTO switch in the joystick switch
panel. Refer to the Startup procedure in the Op-
eration section of this manual.
The lift arm is equipped with hydraulic cylinders
that raise and lower the arm or apply variable
down pressure on the arm and cutter. Down
pressure is set by the operator on the digital
controller. Once down pressure is set, the
cylinders allow the arm to float while Maintaining
consistent down pressure on the cutter. This allows
Cutter Lift Arm
the cutter and truck to follow the contour of the
pavement without causing damage to the cutter
or pavement.
WARNING
AS THE LIFT ARM MOVES UP AND DOWN PINCH POINTS
ARE FORMED THAT CAN CAUSE SEVERE INJURY OR EVEN
DEATH IF HANDS, FEET, HAIR, JEWELRY, LOOSE CLOTHING,
ETC. GET CAUGHT IN THESE PINCH POINTS. ALWAYS MAKE
SURE ALL PERSONNEL ARE WELL CLEAR OF CUTTER
COMPONENTS AND LIFT LINKAGE BEFORE RAISING THE

Locking Arm And Lock Mechanism
When the arm is raised to the full up position, the
arm locking mechanism can be engaged to secure
the arm in the up position for travel. This is a
safety feature that prevents the arm from being
lowered accidentally or drifting down while the
vehicle is operating in Travel mode.
