3.16 SLEWING OPERATION
• Check the safety in the vicinity and honk the horn before slewing.
• Perform the slewing operation as slowly as possible. Make sure to start smoothly, slew at
low speed, and stop quietly. Especially avoid sudden lever operations when the load is
hoisted, which may cause the load to waggle and cause the Machine to lose balance, and
thus may damage the crane or trip the Machine.
• Pulling-in and raising work of a load by performing the slewing operation is prohibited. Be
sure to perform the hook hoisting operation to lift a load.
Operate the left work equipment operation lever (2) as
follows.
• Left slewing:
Push the lever outside (left side).
• Neutral: Release your hand from the lever.
The lever returns to the neutral position
and the slewing stops.
• Right slewing: Pull the lever inside (right side).
NOTES
• Adjust the crane slewing speed by the stroke of the left
work equipment operation lever (2) and depression
amount of the accelerator pedal (4).
• There is a horn switch (5) in the centre of the knob of the
right work equipment operation lever (3). Use the switch
to give a signal when performing the slewing operation.
CAUTION
The gross rated load is the same in all directions
regardless of the slewing stop position.
