ADJUSTING THE PARKING BRAKE (continued)
On this machine the parking brake when fully engaged disconnects the transmission drive.
The machine is prevented from driving with the park brake engaged. To complete the test
move the park brake lever fractionally forward until the warning light is extinguished; hold
the lever in this position for the duration of the test. DO NOT move the lever too far
forward, otherwise the park brake will not be fully operational.
•
With the parking brake engaged select third gear.
•
Make sure the brake pedals are engaged, push down hard on the brake pedal and select
forward drive.
•
If the dumper starts to move forward during the test, immediately apply the foot brake and
reduce the engine speed.
•
Slowly release the brake pedals, if the dumper has not moved use the accelerator to
gradually increase the engine speed (ABOUT HALF WAY UP REV RANGE). The
dumper should not move. DO NOT test for longer than 20 seconds.
•
If the dumper moved inspect the calliper/pads and reset as described in the text.
DO NOT use a machine with a faulty parking brake.
Non approved modifications to axle ratios, machine weight or wheel and
tyre sizes may adversely affect the performance of the parking brake.
