Increasing Load on the Driving Axle (trailing axle lift)

The drive axle load is increased by pressing
this switch. Increase in drive axle load is
often an advantage when moving on slippery
surfaces.
Pressing this switch increases the load on the
driving axle by removing the suspension load
on the trailing (non-driving) axle.
The unweighting continues until one of the
following takes place:
•
speed of the bus rises above 30 km/h (20
mph)
•
the switch is pressed again
