Switching on the
suspension
The suspension cylinders are enabled when the suspension is switched on.
This state must be established for on-road driving.
• Select and confirm the symbol (1).
When the suspension is switched on, the symbol (2) is green.
If the (2) symbol stays red, the supply pressure may be too low. In this case the
suspension will only be switched on if sufficient supply pressure is built up;
à building supply pressure, p. 5 - 9.
Switching off the
suspension
When the suspension is switched off, the suspension cylinders are locked.
This state is intended only for crane operation.
• Select and confirm the symbol (1).
When the suspension is switched off, the symbol (2) is red.
G
Danger of overturning when switching on the suspension!
Do not switch the suspension on unless the truck crane has been rigged for
on-road driving and the main boom has been set down.
If the rigged truck crane was standing on its wheels the suspension struts will be
suddenly pushed together when the suspension was switched on, causing them
to be damaged and possibly causing the truck crane to overturn.
S
Risk of damage to the axle lines!
Always switch the suspension on for on-road driving.
The axle lines may become damaged and the steering behaviour may change if
the suspension is switched off.
