2.16 OPERATION BEFORE CRANE WORK
CAUTION
• Before operating the crane, make sure that all lamps on the outrigger indications are
lit in green. Crane operation cannot be performed if any one of the four outrigger
extension lamps and the four outrigger grounding lamps on the monitor is blinking.
• Before operating any control lever for the crane or the outrigger switches, be sure to
set the lock lever to the lock position.
• When loosening the wire rope for the stowed hook block, be careful not to allow the
entire hook block to fall sideways on the ground due to the wire rope being
excessively loosened. Failure to observe this may result in an irregular winding of the
wire rope in the winch drum.
• When loosening the wire rope for the stowed hook block, there is a danger that the
swinging hook block could be damaged due to interference with peripheral devices.
Pay thorough attention around the hook block.
Perform the following operations before crane work.
1. Shift the lock lever (1) into the free (F) position.
2. Change the mode to Crane with the mode selector
switch (1) (Travel/Outrigger/Crane) on the monitor or
the left control lever.
NOTES
In the event outriggers are not set, if you switch to crane
mode, error code “EOR00” comes up, but this is not a
failure. Set outriggers first, then switch to the crane
mode.
3. Push the right control lever (1) forward to loosen the
wire rope for the hook block from the stow position.
