Selecting the
transmission
mode
Which transmission mode you can select and how the transmission shifts
depends on whether the crane's hydraulic system is switched on or off.
– Crane's hydraulic system on
You can select only the transmission modes RM or DM.
The 1st gear (forwards or reverse) is always engaged.
In order to carry out crane movements after the truck crane is halted,
you must switch to neutral position (or apply the parking brake).
– Crane's hydraulic system off
You can select all transmission modes.
In transmission mode D the transmission shifts up to max. 6th gear.
The transmission modes DM and RM are intended for the manoeuvring
mode. This allows you to start moving more slowly that with the trans-
mission modes D or R.
