6.8.3 Differential lock
The differential locks for the front and rear axles can be activated independently of
each other. The front axle is switched on/off with the key (22) and the rear axle with the
key (23) on the keypad II.
ATTENTION
Hazard of severe damage to the axles.
If you do not observe this note, then the claw clutches of the differential locks may be
destroyed.
– The differential lock may ONLY be switched when the machine is at a complete
standstill (0.0 km/h).
– Never steer the wheels sharply with the differential lock switched on! Always set
the wheels before switching on into running straight ahead position! The power
transmitting components (differential drive, cardan shaft, planetary drive, etc.) are
highly stressed.
ADVICE
If machine traction is insufficient under demanding conditions, then first switch on just
the differential lock of the front axle.
The rear axle lock should only be used if further work would otherwise be impossi-
ble. To avoid damage to the axle, the wheels must in any case be steered in approxi-
mately straight position.
If the steering angle of the front or rear axle is excessively turned in a particular direc-
tion, then the differential lock cannot be engaged.
Only switch on the differential locks if they are actually needed. Use of the differen-
tial locks is not required when operating on normal terrain or with correctly set pickup
depth, pickup relief and counterweight position.
