Slewing gear
freewheel
The slewing gear freewheel is required if the slewing gear needs to be
slewed by means of external forces, e.g. when operating with two cranes.

• Shift the control lever (2) to its initial position.
• To do this, press button (3) or button (1) in the case of additional equip-
ment.
The slewing gear brake will be released – lamp (4) will not light up.
Switching off the
slewing gear
If the slewing gear is not required, it should be switched off to avoid
unintentional use.
• Press the button (1) once.
– The lamp in the button (1) lights up dimly.
– Symbol (2) will be red if the slewing gear is switched off.
– The slewing gear brake is applied – lamp (3) lights up.
S
Risk of damage to the main boom!
Brake the slewing movement down to a standstill before you switch off the
slewing gear. The slewing gear brake is automatically applied when the
slewing gear is switched off.
This prevents lateral forces from affecting the main boom due to long
delays or swinging loads.
