8-12 CARE AND MAINTENANCE

PA1633 X3-45 Commuter Operator’s Manual

vibrate loose or fail over time, inspect frequently
and tighten or replace as necessary.

Correct leaking hoses immediately. Failure to
correct leaks can cause severe damage to the
equipment, as well as increase operating costs
due to lost fluids. Treat fuel and oil leaks as an
immediate fire hazard.

WARNING

Personal injury and property damage may
result from fire caused by leaking flammable
fluids.

Hose Service Life

Hoses have a limited service life. Thoroughly
inspect hoses annually. Look for surface
damage or indications of twisted, worn, crimped,
cracked or leaking lines. Replace damaged
hoses immediately.

Hoses should be replaced during major overhaul
or after a maximum of seven years service. Be
certain replacement hoses match the original
equipment manufacturer's specifications.

LUBRICATION

Grease all lubrication points during scheduled
maintenance. For heavy loads or extended use,
lubricate more often. Refer to the Maintenance
Manual, section 24 for information on lubrication.

WHEELS AND TIRES

Check for loose wheel nuts. Inspect all types of
rims for cracks. Cracks can appear in many
places but typically radiate out from where a
load is applied. Steel wheel nuts should be
tightened to 450 to 500 foot-pounds (610 to 680
N.m.) torque.

Keep the tires inflated to the recommended
inflation pressure to prolong tire life and for
safety.

NOTE

Recommended tire inflation pressures are
given in the "Coach Final Record", placed in
the technical publications package supplied
with the vehicle. The cold tire inflation
pressures are on the Department of Transport
certification plate located on the L.H. console
besides the driver’s seat. When special tires
are installed by Prevost on a new vehicle, a
special tire inflation chart is added next to the
certification plate.

WARNING

Do not exceed maximum inflation pressure.
Incorrect tire pressure increases tire wear and
could lead to loss of driving control because of
reduced road handling. Check tire pressure
regularly.

WHEEL BEARINGS

Check wheel bearing cover for overheating
(especially after using the service brakes) during
fuel stops by touching the wheel bearing cover.

WARNING

If replacement tires are different from those
described on the certification plate, pressure
must be adjusted as requested in the Tire and
Rim Association Manual.

SERVICE BRAKE TEST

Check for correct pressure build-up. Stop
engine and check pressure gauge. Pressure
loss should not exceed 3 psi/min (21 kPa/min)
with engine stopped and without brake pedal
applied. Air loss should not exceed 7 psi/min (48
kPa/min) with engine stopped and brake pedal
fully applied.

A convenient way to proceed to the service
brake test is with the use of the DID menu “Air
Leakage Monitor”. For more information, refer to
“Driver Information Display (DID) Menus” in
Section 5

Other Features

PARKING BRAKE TEST

Release parking/emergency brake. Pump
service brake pedal until air pressure drops to
65 psi (448 kPa). Make sure the warning buzzer
operates and that the emergency brakes apply
(the control valve knob lifts up). Allow air
pressure to reach 95 psi (655 kPa) before
releasing parking brake.

Driving the vehicle while the parking brake is
applied should not be possible.
