Driving out:
Not to be used for DP variants
It is safer to drive ‘driven’ axles out of the rollers with the brake tester motors
running. This eliminates any problems of over speeding the rollers and drive motors,
particularly when the vehicle under test has an automatic gearbox.
Select next axle by pressing
AXLE
and
DOWN ARROW
, then press
START
to
power both motors as if the wheels were being centralised and drive the wheels out
of the rollers. Brake tester motors will stop once the wheels leave the rollers.
