Operating the transmission
When the Driving operating mode is switched on, the transmission is in
neutral position – letter N (1) white.
You can select transmission modes with crane functions and transmission
modes without crane functions.
Risk of accidents when driving with a lifted load
Secure the load when driving so that it cannot swing and use the transmis-
sion mode DM or RM so that the transmission does not shift.
In this way you can prevent the swinging load leaving the permissible
working range and the truck crane overturning.
Transmission modes without crane functions
•
Switch to transmission mode D or R.
– The crane's hydraulic system Driving mode is switched off – symbol (1) is
grey.
– The transmission shifts.
– The speed is limited to approx. 20 km/h (12 mph).
Transmission modes with crane functions
•
Switch to transmission mode DM or RM.
– The crane's hydraulic system Driving mode is switched on – symbol (1)
orange.
– The transmission shifts only into the 1st gear (reverse or forwards).
– The speed is limited to approx. 5 km/h (3 mph).
In these transmission modes you can start moving more slowly than in the
transmission modes D or R. These transmission modes are intended for
manoeuvring mode and for driving with a load.
The crane functions are also available in the neutral position N.
