Engine starting (with parking brake applied)
Air brake check:
Check the air brakes in the following manner
(Chock the wheels, if necessary. Push in the
parking brake and on tractors, also push in the
tractor protection valve knob):
1. Check the air compressor or governor
cut-out pressure (approximately 305 kPa [120
psi]).
2. Cut-off the engine and turn the key back to
ON, without starting the engine.
3. Without the brake pedal applied, note the
air pressure drop for one minute. It should be
less than 5 kPa (2 psi) for single vehicle and 8
kPa (3 psi) for combination vehicles.
4. Depress and hold the brake pedal with 621
kPa (90 psi) or more and make sure there is
no more than a 8 kPa (3 psi) per minute leak.
For combination vehicles, no more than 10
kPa (4 psi) per minute.
5. Step on and off the brake pedal and check
for the warning light and chime to activate
between 163-193 kPa (64–76 psi).
6. Step on and off the brake pedal and make
sure the tractor protection and parking brake
knobs pop out between 138–310 kPa (20–45
psi)
7. Restart the engine, shift to a lower gear and
gently pull against the service and parking
brakes separately to make sure they hold.
Automatic
transmission fluid:
With the engine idling (at normal operating
temperature) and the parking brake applied,
check the automatic transmission fluid. If fluid
needs to be added, place the transmission in
the appropriate gear as specified in the
transmission operator’s manual and refer to
Transmission fluid
in the
Maintenance and
specifications
chapter.
