Switching off the
slewing gear
If the slewing gear is not required, it should be switched off to avoid uninten-
tional use.
• Press the button (1) once.
– The lamp in the button (1) will light up dimly.
– Symbol (2) will be red if the slewing gear is switched off.
– When the Brake pedal function is switched on – the slewing gear brake is
closed – the 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 slew-
ing gear. The slewing gear brake is automatically applied when the slewing gear
is switched off.
This prevents excessive lateral forces affecting the main boom due to heavy
deceleration or swinging loads.
