Crane Stowing Operation
CAUTION: The hook stowing switch cancels
the auto stop function of the over winding
detector.
Operate the winch lever carefully not to let the
hook block hit the boom when stowing the
hook block.
CAUTION:
• Stop the slew of the hook block before
stowing the hook block.
• When stowing the hook block, do not topple
the entire hook block sideways on the
ground by loosening the wire cable too
much. This will cause the irregular winding
on the winch drum.
• The boom "retracting" operation will lower
the hook block. The hook block also lowers
with the boom "lowering" operation. Raise
the hook at the same time so that the hook
block will not touch the ground or interfere
with the machine.
• Stow the boom securely into the stowing
position. After stowing the boom, verify that
the boom stowing lamp on the outrigger
display lights up in green. If the boom
stowing lamp does not light up, the
outriggers cannot be stowed. If the boom
stowing lamp does not light up, lower the
boom to the maximum or slew the boom to
verify that the boom stowing lamp lights up.
1. Operate the boom telescoping lever (2) to the
"RETRACT" (pull toward you) side to fully
retract the boom.
Fig. 4-156
2. Operate the slewing lever (1) to the "LEFT"
side, and slowly slew the boom
counterclockwise (left) to the operation of
7 degrees left from the centre of the machine.
When the boom comes to the stowing
position, slew stops automatically.

NOTICE: Operate with the slew lever and do not
use the remote control.
3. Operate the boom derricking lever (4) to the
"LOWER" (push forward) side and lower the
boom until it automatically stops.
