Operating instructions
66 Operating with differential locks
Longitudinal differential lock / 6-wheel drive
Q Engagement of the longitudinal differential lock automatically
causes the 6-wheel drive to be engaged as well.
Q The longitudinal differential lock and 6-wheel drive (6x6) is
used when operating on soft and slippery ground and on steep
inclines.
Q Engagement and disengagement can be made while operating
regardless of travelling speed.
Q The control lamp for longitudinal differential lock /6-wheel drive
on the instrument panel is on.
Q The control lamp in the switch is on.
NOTE! The longitudinal differential lock / 6-wheel drive must
be disengaged when operating on good ground and at high
travelling speed.
Transverse differential lock, front axle
Q Only use the transverse differential lock on the front axle
separately when the ground is very slippery but firm to maintain
the best possible steering ability of the machine.
Q Disengage the lock when operating on firm ground.
Q The control lamp on the instrument panel for the differential lock
on the front axle will be alight.
Q The control lamp in the switch will be alight.
Longitudinal differential lock / 6-wheel drive +
transverse differential lock, front axle
Q Provides the best possible traction with maintained steering
ability on soft and slippery ground.
Q Disengage the lock when operating on firm ground.
Q Both the control lamp for the longitudinal differential lock and
the control lamp for the differential lock on the front axle, will be
alight on the instrument panel.
Q The control lamp in the switches will be alight.
All differential locks / 6-wheel drive
Q Is used when operating where traction force is required.
Q The following control lamps on the instrument panel will be
alight:
– Longitudinal differential lock/6-wheel drive
– Differential lock, front axle
– Differential lock, bogie axle (front)
– Differential lock, bogie axle (rear)
Q The control lamp in the switches for the differential locks will be
alight, even if the switches are in position 0.
NOTE! The steering ability of the machine is reduced.
