Before Crane Operation
NOTICE:
Stow the travel lever before operating the crane
operation levers or outrigger switches.
If the travel lever is not pushed in, the interlock will
engage, preventing the crane operation levers
and outrigger switches from operating.
When unhooking the hook block from the hook
hanger, make sure the wire rope does not have
excessive slack and that the hook block does not
rest on the ground. This will help avoid tangling on
the winch drum.
Perform the following operations before operating
the crane:
1. Verify that the Moment Limiter Override
Switch is at the “OFF” position.
The safety device operation will not stop if at
the “ON” position.

If the Moment Limiter Override Switch is “ON”
(Override), the Working Status Lamp will flash in
red, and an alarm buzzer will sound intermittently.
2. Switch on the Home screen on the monitor.
NOTICE: The crane cannot be operated while in
Outrigger mode.
3. Push in the travel lever while unlocking the
lever to enable crane operations.
