Bogie
Pressing the bottom of the switch will release compressed
air from the bogie air bellows as long as it is depressed. The
rear axle weight will then be transferred to the drive axle
only, which is an advantage when pulling away on slippery
surfaces.
Engaging the differential lock while either wheel is
spinning will inevitably cause damage
to the differential lock’s toothed coupling.
Differential lock (option)
Release the catch and press the switch to engage the differ-
ential lock.
The following must be observed when engaging:
Engage a suitable gear, depress the clutch, engage the dif-
ferential lock. Carefully release the clutch pedal with the
clutch slipping.
The differential lock may be used on slippery surfaces
only. Engage just before the bus reaches the slippery sur-
face. It can be engaged while in motion, irrespective of
speed, and also under load but not in bends or during
wheel spin.
See page 25 if the bus is equipped with ASR.
