2.16 OPERATIONS 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 setting lamps is flashing in red.
• Set the traveling 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 rope too much. This will cause irregular winding
on the winch drum.
• When loosening the stowing of the hook block, the hook block may swing and interefere 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 traveling lock lever (8) to the “LOCK” position.
2. Operate the work selector switch on the outrigger operation
panel to the ”CRANE” position.
3. Operate the winch lever (3) to the “DOWN” (push forward) side
to loosen the hook block from the stowing position.
