5.4.1 Longitudinal and transverse differential locks
– The longitudinal differential locks prevent individual axle lines from spin-
ning when driving on a slippery surface. With the 10 x 8 x 10 drive, the
3rd axle line is switched on and off together with the longitudinal differ-
ential locks.
– The transverse differential locks prevent individual wheels from spinning
when driving on a slippery surface.
For switching on and off, the current speed needs to be under approx.
5 km/h (3 mph).
