Rear of vehicle
Air/Electric lines:Make sure that air hoses are not cut, cracked,
chafed or worn. Listen for audible air leaks.
Make sure air and electrical lines are not
tangled, crimped or pinched or being dragged
against any truck parts. Electrical line
insulation should not be cut, cracked, chafed
or worn. None of the air or electrical line
should be spliced or taped. Check for
corrosion on pins and in electrical sockets to
ensure continuity and reduced heat build-up
potential.
Deck plate:Make sure deck plate is clean, securely bolted
to the frame and clear of loose objects.
Signal/Brake lights:Make sure both brake lights illuminate when
the brake pedal is applied. Also, make sure
each signal flashes. Make sure that four-way
flashers work properly.
Lights, reflectors:Make sure all lights illuminate and are clean.
Make sure reflectors are clean, unbroken and
of proper color (red on rear, amber
elsewhere). Make sure the running lights are
also clean and unbroken. Rear running lights
must be checked separately from signal,
flasher and brake lights.
Tractor - coupling system
Mounting bolts:Check for loose or missing mounting brackets,
clamps, bolts or nuts. Both fifth-wheel and
slide mounting must be solidly attached.
Platform:Check for cracks or breaks in the platform
structure.

that are in contact, or nearly contacting a tire,
rim, brake drum, frame or body component.
Check for missing or broken leaves in the leaf
spring.
Spring mounts:Check for cracked or broken spring hangers,
broken, missing or loose bolts, missing or
damaged bushings, broken, loose or missing
axle mounting parts.
Torsion, shocks:Make sure torsion arm is not cracked, broken
or missing. Check the shock absorber for
cracks or leaks; there should be no missing or
broken mounting bolts or worn bushings.
Rear brakes
Hoses:Check for cracked, worn or frayed hoses. Make
sure all couplings are secured.
Chambers:Make sure brake chambers are not cracked or
dented and that they are securely mounted.
Slack adjuster:Check for broken, loose or missing parts. The
angle between the push rod and adjuster arm
should be approximately 90° when the brakes
are applied. When pulled by hand, the push
rod should not move more than approximately
one inch (2.5 cm).

Rear brakes
Drum:Make sure there are no cracks, dents or holes
and no loose or missing bolts. Make sure brake
linings are not worn, dangerously thin or
contaminated by lubricant.
Rear wheels
Spacers:Make sure dual wheels are evenly separated
and that tires are not touching one another.
Rims:Check for damaged or bent rims. Rims should
not have welding repairs and no rust trails that
indicate it is loose on the wheel.
Lug nuts:Make sure all lug nuts are present and not
loose (look for rust trails around the lug nuts).
There should be no cracks radiating from the
lug bolt holes or distortion of the bolt holes.
Trailer
If you are pulling a trailer, an inspection of the trailer similar to that of
the tractor should be done. Such an inspection should follow 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.
Transmission
If your vehicle is equipped with an automatic transmission, regularly
check the transmission’s neutral start switch. The engine should only
start in the N (Neutral) or P (Park) positions.
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.
Check the transmission fluid level and shift linkage for proper operation.

•Always shift to a lower gear at high altitudes to prevent engine
smoking.
•Operate in a gear that will permit an engine speed not in excess of the
maximum governed speed or high-idle RPM (no load).
•Normally, choose the same gear to descend the hill that you would use
to ascend the hill.
WARNING:All vehicles have blind spots. To reduce the risk of
severe injury or property damage, never move your vehicle to
the side or rear or change lanes without being sure your way is clear
on both sides and to your rear.
Backing up
WARNING:To reduce the risk of the possibility of personal
injury while backing the vehicle, always be sure your vehicle’s
path is clear.
Before backing your vehicle, be sure you can do so safely. If anything
behind the cab limits your view, do not rely on mirrors alone to ensure
that your intended path is clear. If other people are in the vicinity, have
someone standing well behind your vehicle and outside of your intended
path (visible through an exterior mirror) guide you as you back up.
Although OSHA or some governmental regulations may require the use
of an electrical or mechanical back-up alarm to warn bystanders, such an
alarm does not ensure that the intended path is clear. When in doubt,
get out of the vehicle and visually check the intended path is clear;
back-up slowly as to allow others time to move, if necessary.
If an electrical back-up alarm is installed, it should be connected to the
back-up lamp circuit.
Parking your vehicle
Always use the parking brake. When parking on a grade, block the
wheels and turn the front wheels to one side so that if the vehicle rolls,
the front tires will act against the curb to stop the vehicle. The front
wheels will be more effective at stopping a rolling vehicle than the rear
wheels.

WARNING:If the red BRAKE warning lamp in the instrument
cluster remains illuminated after engine start up, this indicates a
system failure in the Full Power Brake System. Stop the vehicle safely
as soon as possible and seek service immediately.
Note:During normal driving the pump/motors may be heard
replenishing the accumulators. This is a normal function of the Full
Power Brake System.
Parking brake
Apply the parking brake whenever
the vehicle is parked. To set the
parking brake, pull handle up until it
snaps into the locked position.
WARNING:Do not use the
gearshift selector in place of
the parking brake. Always set the
parking brake fully AND make
sure the gearshift selector is in R
(Reverse) for vehicles equipped
with manual transmission, P
(Park)(if equipped)or N
(Neutral) for vehicles with
automatic transmission. Use of
wheel chocks is also
recommended in hilly or off-road
usage.
WARNING:Unexpected
and possible sudden vehicle
movement may occur if these
precautions are not taken.
When the parking brake is out of adjustment, seek service immediately.

The parking BRAKE warning lamp
in the instrument cluster illuminates
and will remain illuminated (when
the ignition is turned on) until the
parking brake is released.
Push the palm release lever on the
parking brake handle and push
down as far as possible to release
the brake. Driving with the parking
brake on will cause the brakes to
wear out quickly and reduce fuel
economy.
WARNING:If the parking
brake is fully released but
the parking brake warning lamp
remains illuminated, the brakes
may not be working properly. See
your dealer or a qualified service
technician.
The parking brake is not
recommended to stop a moving vehicle. However, if the normal brakes
fail, the parking brake can be used to stop your vehicle in an emergency.
Since the parking brake only applies retardation to the rear wheels, the
vehicle’s stopping distance will increase greatly and the handling of your
vehicle will be adversely affected.
POWER PARK (PARKING BRAKE) OPTION (IF EQUIPPED)
This feature uses a brake chamber mounted on the chassis to power a
spring-applied, hydraulic-released driveline parking brake. It is controlled
by a yellow, dash-mounted parking brake knob.
The Power Park Brake is controlled by the park brake dash-mounted,
yellow knob-type switch. The switch has three positions: apply (out),
