CHANGING A FUSE

Fuses

WARNING:

Always replace a fuse

with one that has the specified
amperage rating. Using a fuse with a
higher amperage rating can cause severe
wire damage and could start a fire.

E217331

If electrical components in the vehicle are
not working, a fuse may have blown. Blown
fuses are identified by a broken wire within
the fuse. Check the appropriate fuses
before replacing any electrical
components.

VEHICLE INSPECTION
INFORMATION

To make sure your vehicle is ready to
operate, conduct a pre-trip inspection at
the beginning of each work period. Follow
the steps listed in this section to verify a
proper vehicle inspection procedure.

WARNING:

Exercise great caution

when working on a vehicle equipped with
an automatic fan clutch. The fan starts
in motion only after the engine coolant
reaches a predetermined temperature
or the refrigerant pressure (if equipped
with air conditioning) reaches a
predetermined setting. The fan starts at
this point with no advance warning.
Never reach near, or permit objects to
protrude into, the fan blade radius while
the engine is running as this could result
in vehicle damage, personal injury or
death.

WARNING:

Do not operate the

vehicle if any suspension conditions
listed in the following charts are evident.
Loss of steering or suspension could
result in property damage, personal injury
or death.

WARNING:

If a wheel must be

changed, obtain expert tire service help.
Mounting and un-mounting of tires
should only be performed by a qualified
technician using necessary safety
procedures and equipment, otherwise
the result could be property damage,
personal injury or death.

Note:

Always make sure you apply the

parking brake before starting the engine.

Engine compartment (with engine off)

Use the dipstick to verify the oil level is in the proper operating
range. See

Engine Oil Dipstick

(page 223).

Engine oil

Look through the plastic reservoir and verify the coolant level
is within the proper operating range. Do not remove the
pressure cap until the coolant has cooled. See

Engine

Coolant Check

(page 237).

Engine coolant

Verify that the fluid level is in the proper operating range. See

Power Steering Fluid Check

(page 244).

Power steering fluid

Remove the master cylinder caps and inspect the fluid level.
See

Brake Fluid Check

(page 243).

Brake fluid

209

Vehicle Inspection Guide

Engine compartment (with engine off)

Inspect for glazing, fraying or cracking. There should be no
more than 5-7 cracks per rib, per 1 in (2.5 cm)

Belts (fan, alternator,
water pump and air
conditioning
compressor)

Inspect for signs of fluid puddles or dripping fluid on the
ground under the engine, or the underside of the engine.

Fluid leaks

Inspect for debris that may have collected on the HVAC air
inlet grille or inside the exterior module as this may reduce
system performance.

HVAC air inlet

Engine starting (with parking brake applied)

Before entering the cab, verify that the vehicle is equipped
with spare electrical fuses (if used), three red reflective
triangles, a properly charged and rated fire extinguisher and
wheel chocks.

Safety and emergency
equipment

Walk around the vehicle and verify all steps and grab handles,
inside and out (as well as behind), are tight and clean. Use
extreme caution and a three-point stance at all times.

Inspect door latches for proper closing, latching and locking.

Set the parking brake. Make sure the gearshift lever is in
neutral (N) or park (P) (if equipped with a park position).

Starting the engine

Diesel engine:

Turn the key to the on position. Turn the key

to start when the wait to start indicator light in the instrument
cluster turns off.

Gasoline engine:

Turn the key to start, and then release it

as soon as the engine starts.

Verify pressure builds to normal operating range.

Engine oil pressure

A tone indicating low air pressure should sound immediately
after the engine starts but before the compressor has built-
up pressure. The tone should stop when the air pressure
reaches 70 psi (483 kPa). Let the air pressure build to
governed cutout pressure, which should occur between
115–130 psi (793–896 kPa).

Low air pressure warning
tone (if equipped with an
air compressor)

Press the accelerator and verify that it operates smoothly,
without any binding or irregular feel. Release the pedal and
verify the engine returns to idle speed immediately.

Accelerator

210

Vehicle Inspection Guide

Engine starting (with parking brake applied)

Check the gauge (diesel engine) or indicator light (gasoline
engine) to verify the alternator is charging.

Voltmeter

Inspect for excessive free play in the steering linkages. The
steering wheel should have less than 2 in (5 cm) of free play
at its rim.

Steering linkage free play

Verify the parking brake holds the vehicle by gently trying to
pull forward with the parking brake applied.

Parking brake

Verify operation using the following procedure. Chock the
wheels, if necessary. Push in the parking brake and, on
tractors, push in the tractor parking brake knob:

Air brakes

1. Verify the air compressor or governor cutout pressure is
approximately 120 psi (827 kPa).

2. Turn off the engine, and then turn the key back to the on
position (without starting the engine).

3. Without the brake pedal applied, note the air pressure drop
for one minute. It should be less than 2 psi (14 kPa) for single
vehicles and 3 psi (21 kPa) for combination vehicles.

4. Press and hold the brake pedal with 90 psi (621 kPa) or
more. Make sure there is no more than a 3 psi (21 kPa) per
minute leak for single vehicles and a 4 psi (28 kPa) minute
leak for combination vehicles.

5. Pump the brake pedal to deplete the system of air pressure.
The warning light and tone should turn on at 57 psi (393 kPa).

6. Pump the brake pedal and make sure the parking brake
and trailer parking brake knobs pop out at 20 psi (138 kPa)
or higher.

Verify that the fluid level is in the proper operating range. See

Automatic Transmission Fluid Check

(page 241).

trailer manufacturer recommendations
and should include at a minimum: general
condition, landing gear, doors, sides, lights,
reflectors, suspension, brakes, tires,
wheels, cargo placement, stability and
tie-downs.

WARNING:

If the unit starts in gear

and/or the neutral start switch is not
functioning correctly, the vehicle may
inadvertently move which could result
in property damage, personal injury or
death.

Regularly inspect the transmission's
neutral start switch. The engine should
only start in neutral (N) or park (P) (if
equipped with a park position).
