NORMAL OPERATION CONTINUED
WARNING
If any of the warning lights and audible warnings associated with the braking systems illuminate or
sound during the normal operation of the machine, stop the machine immediately. Do not use a
machine with a brake system warning light illuminated or an audible warning device sounding.
Failure to follow this warning could cause injury or death to personnel.
Brake Fluid. A warning lamp (Figure 5, Item 7) will illuminate and the audible warning will sound if the level in either of
7.
the four reservoirs falls too low. Shut down the engine as soon as it is safe to do so and troubleshoot (WP 0008).
NOTE
When the engine is started, the pressure builds up progressively though the circuits. The warning
lights for the front and rear brake circuits should go out before the warning light for the parking
brake. The foot brakes require air pressure to apply them, while the parking brake requires air
pressure to release. This ensures the machine cannot be driven away until there is sufficient air
pressure to operate the foot brake.
Front Brake Circuit Air Tank Pressure. A warning lamp (Figure 5, Item 7) will illuminate and the audible warning will

sound if the air pressure is low in the relevant circuit.
9.
Rear Brake Circuit Air Tank Pressure. A warning lamp (Figure 5, Item 7) will illuminate and the audible warning will
sound if the air pressure is low in the relevant circuit.
