You can adjust the sensitivity of the control levers to the operating condi-
tions;
à Setting the characteristic curves for the control levers, p. 11 - 106.
You can regulate the speed by moving the control lever and changing the
engine speed with the accelerator.
H
The maximum slewing speed is automatically reduced as the working
radius is increased. At a degree of utilisation above 50%, the speed will be
halved again.
At a degree of utilisation under 50%, the speed will only be increased again
if the control lever is brought into its initial position and the slewing gear is
stationary.
You can set the desired engine speed (idling speed) with button (1);
à p. 10 - 16.
You can limit the maximum slewing speed;
à p. 11 - 105.
G
Danger of overturning when slewing with an incorrectly set RCL!
Before slewing, always check whether the RCL code valid for the current
rigging mode is displayed.
This prevents slewing operations from being enabled within the impermis-
sible ranges, which would cause the truck crane to overturn.
G
Risk of crushing during slewing!
Before slewing, operate the horn and ensure there are no persons in the
slewing range.
This prevents persons from getting crushed between the superstructure
and the carrier or between the superstructure and other parts.
S
Risk of the main boom buckling!
Do not accelerate the slewing speed to such a degree that the load starts
swinging.
To slew to the left: • Push the control lever to the left.
To slew to the right:
• Push the control lever to the right.
