Handler with telescopic boom
GTH-3512
OPERATING INSTRUCTIONS
C-3.4 CONTROL LEVER
The handlers are equipped with a joystick with servo-
assisted hydraulic control for the boom lifting/lowering
movements and the attachment frame forward/back
pitching. Pressing the red button
1
on the joystick
switches the pitching movement to telescope out/in-
movement.
The control lever has an intentional control button
that must be pressed and held in position till the end
of the movement.
If the button is not pressed down, the lever, though
operated, does not perform any function.
Other three levers are installed on the dashboard for
the independent operation of the following functions:
right and left outrigger movement and attachment
locking/unlocking (optional).
IMPORTANT
Seize the control lever correctly and move it gently.
The motion speed of the actuators depends on the
lever position: a small movemennt results in a slow
motion of the actuators; vice versa, a full range
movement of the lever corresponds to the max.
speed of the actuator.
CAUTION
The control lever shall be operated only when
correctly seated in the driving place.
CAUTION
Before operating the control lever, make sure that
nobody is within the working range of the machine.
