* Coolant protection checks should be made just prior to the onset of
freezing weather, where applicable. If coolant is dirty or rusty in
appearance, the system should be drained, flushed and refilled with the
prescribed solution of cooling system fluid and water. Use only
permanent type coolant that meets specifications as listed in your
engine operator’s manual. See the engine manufacturer’s operating
guide for supplemental corrosion inhibitor specifications.
In addition to the items to be performed daily or at each oil change, the
following need to be completed as specified:
GENERAL MAINTENANCE SERVICES
The following are vehicle checks that should be made periodically either
by the owner or a qualified technician. It is recommended that
deficiencies be brought to the attention of your dealer or another
qualified service outlet as soon as possible in order that advice regarding
the need for service or replacement can be obtained.
Maintenance Operation Frequency - Observation
Inspect the automatic slack
adjuster functionInsufficient power shown in loaded
practice stop.
Check the operation of the
brakes, the clutch, and the
steering
(1),(2)
Vehicle handling qualities not up to
par.
Inspect the vehicle for missing,
damaged, or mislocated noise
shieldsExcessive noise emanates from under
the cab or engine compartment.

Maintenance Operation Frequency - Observation
Check the engine performance
and the engine governorExcessive engine noise.
Inspect the fan, the fan shroud,
and the fan clutchEngine overheats, fan runs at high
speed constantly, excessive fan noise,
or fan wobble due to worn bearings.
Check for operation of ABS
warning lampAt each engine start up.
Inspect the entire exhaust
system (including inlet pipe,
muffler, outlet pipe and all
exhaust clamps and fasteners)
for holes, leakage, breakage,
looseness and corrosive
damageExcessive noise or the smell of fumes
is experienced.
Inspect the engine air
induction system (including the
air ducts and the air filter) for
loose fitting, damaged or
missing componentsExcessive noise emanates from the
engine compartment.
Inspect the tires and check the
air pressure
(3)Poor steering, wandering or excessive
tire wear.
Balance the wheels and the
tiresVibration or abnormal tire wear
indicates imbalance.
Check the front end alignment
(3)Poor steering, wandering or excessive
tire wear.
Check the transmission and
engine mountings
(2)Hard shifting or excessive vibration.
Check and adjust transmission
controls
(2)High effort to shift or noisy
transmission.
Check fuel pump pressure Insufficient full-throttle power or
backfiring.
Clean radiator cap seal. Clean
and inspect the cap surface on
the radiatorWhen the cap does not hold pressure.

Maintenance and
SpecificationschapterRequired initially at 500 and 1000
miles (800 and 1600 km). Perform
again at 500 and 1000 mile (800 and
1600 km) intervals after each tire
removal/replacement.
Clean body/door drain holes At least twice annually.

and mild detergent and washing with
a cleaner does not restore a clean
wipe.
Lubricate body lock cylinders Noisy or difficult to operate.
Check headlamp alignment Lamp beams in wrong position when
vehicle operating loaded.
Check windshield washer fluid
level; add fluid if requiredIf washes do not spray when operated.
1- During maintenance and repair, protect the fuel tube and the hose
assemblies, the power steering lines, and the brake lines from the
external heat, the acids and the abrasion that could damage the lines.
2- Check for (free) linkage action and ensure that (return) spring
force is adequate to maintain pedal free play.
3- Adjust, repair or replace as required with the same or equivalent
parts.
