ROUTINE INSPECTION
WITH ENGINE STOPPED:
Inspect hoses for leaks. Carefully inspect all
fittings, clamps and ties. To prevent chafing,
make sure hoses are not touching shafts,
couplings, heated surfaces, sharp edges or
other parts. Since hose clamps and ties can
vibrate loose or fail over time, inspect frequently
and tighten or replace as necessary.
Check for loose nuts and bolts. Visually inspect
safety of compartment door latches. Test
operation of all exterior lights.
Leaks
Check for leaks under vehicle and in
compartments.
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.
DANGER
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 five years service. Make
sure replacement hoses match the original
equipment manufacturer's specifications.
Wheels And Tires
Check for loose wheel nuts. Both aluminum
alloy and steel wheel nuts should be tightened
to 450 to 500 lbf-ft (610 to 680 Nm) torque.
Tire Pressure
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.
Doors
Close all exterior doors and windows. Check for
good tightness and fit.
Tools And Spares
Make sure the vehicle is equipped with a wheel
nut wrench, door keys, spare belts, reflectors
and jack.
Air System
To drain water from air and accessory tanks,
open drain cocks. Close drains when completed.
Refer to heading "Air Tank Purge" in this
chapter.
Water Separator
To drain water separator, open drain valve.
Close drain valve after draining.
Coolant Level
Check coolant level. Coolant level is correct
when visible in the filler neck of the surge tank. If
coolant level is low, fill system with 50-50
coolant-water mixture. Refer to the vehicle
"Maintenance Manual" for more information.
