Before Crane Operations
CAUTION:
• Verify that all the lamps on the outrigger
display are illuminated in green before
performing the crane operation. The crane
cannot be operated if any of the four
outrigger extension lamps and four
outrigger grounding lamps is flashing in red.
• Set the travelling lock lever to the "LOCK"
position when operating the operation
levers of the crane system and outrigger
switches.
• When loosening the stowing of the hook
block, be careful not to topple the entire
hook block sideways on the ground by
loosening the wire cable too much. This will
cause irregular winding on the winch drum.
• When loosening the stowing of the hook
block, the hook block may slew and interfere
with the peripheral devices, resulting
breakage of the devices. Pay sufficient
attention around the hook block.
Perform the following operations before crane
operation.
1. Operate the travelling lock lever (8) to the
"LOCK" position.
