3.8.4 SLEWING OPERATION
• Check for safety in the vicinity and honk the horn before slewing.
• Operate the left control lever 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 tip the Machine.
• Even if the outriggers are set correctly, the suspended load is slightly unstable in a
specific direction. Exercise caution when slewing the boom with a suspended load.
• In some cases, depending on the configuration of the outriggers, the suspended load
may hit the outriggers, resulting in damage to the crane or overturning of the
machine. Exercise caution to prevent the suspended load from hitting outriggers.
• If someone is sitting in the operator’s seat, be careful so that the boom does not hit
this person when slewing.
Operate the left control lever (1) as follows:
• Clockwise:
Push the lever to the left.
• Neutral:
Release your hand from the lever.
The lever returns to the “NEUTRAL”
position and the slewing stops.
• Counter
clockwise:
Push the lever to the right.
NOTES
Control the crane slewing speed with the left control lever
and accelerator control switch.
