Engine Starting (Parking Brake Applied)
Air BrakesVerify 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:
1. Verify the air compressor or governor cut-out
pressure is approximately 120 psi (827 kPa).
2. Turn off the engine, 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) per minute leak for
combination vehicles.
5. Pump the brake pedal to deplete the system of
air pressure. The warning light and chime should
activate 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.

Front Suspension
SpringsInspect for leaves that may be:
•missing
•broken
•shifted

rim, brake drum, frame or body component.
Note:Never apply grease to spring pads.
Spring MountsInspect the following for cracks, breaks, wear,
damage and tightness:
•spring hangers
•bolts
•bushings
•axle mounting bolts
•nuts.
Shock AbsorbersInspect for:
•cracks
•leaks
•missing or broken bolts or bushings.
Front Brakes
Hoses•Inspect for cracked, worn or frayed hoses.
•Verify all couplings are secured.
Brake ChambersVerify:
•there are no cracks or dents
•they are securely mounted.
Slack AdjustersInspect for broken, loose or missing parts.
Note: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).
DrumsVerify:
•there are no cracks, dents, holes, and no loose
or missing bolts

Brake ChambersVerify:
•there are no cracks or dents
•they are securely mounted.
Slack AdjusterInspect for broken, loose or missing parts.
Note: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).
DrumVerify:
•there are no cracks, dents, holes and no loose
or missing bolts
•the brake linings are not worn, dangerously
thin or contaminated by lubricant.
Rear Wheels
SpacersVerify:
•dual wheels are evenly separated
•the tires are not touching one another.
RimsInspect for damaged or bent rims. Rims should
not have welding repairs, and no rust trails that
indicate it is loose on the wheel.
Lug NutsVerify 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. The 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
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.
If your vehicle is equipped with an automatic transmission, regularly
inspect the transmission’s neutral start switch. The engine should only
start in positionNorP.
Inspect the transmission fluid level and shift linkage for proper
operation.

Safety Belt Locking Modes
WARNING:After any vehicle crash, all safety belts should be
checked for proper function.
All safety restraints in the vehicle are combination lap and shoulder
belts. The driver safety belt and the optional front and rear center seat
safety belt have the first locking mode described below only. All outboard
passenger and outboard rear safety belts have both types of locking
modes described as follows:
Vehicle Sensitive Mode
This is the normal retractor mode, which allows free shoulder belt length
adjustment to your movements and locking in response to vehicle
movement. For example, if the driver brakes suddenly or turns a corner
sharply, or the vehicle receives an impact of about 5 mph (8 km/h) or
more, the combination safety belts will lock to help reduce forward
movement of the driver and passengers.
In addition, the retractor is designed to lock if the webbing is pulled out
too quickly. If this occurs, let the belt retract slightly and pull webbing
out again in a slow and controlled manner.
Automatic Locking Mode
In this mode, the shoulder belt is automatically pre-locked. The belt will
still retract to remove any slack in the shoulder belt. The automatic
locking mode is not available on the driver safety belt or the optional
front or rear center safety belt.
When to Use the Automatic Locking Mode
This mode should be used any time a child safety seat is installed in a
front outboard passenger seating position or any outboard rear seating
position (if equipped). The optional front and rear seat center safety belt
have a cinch mechanism. Children 12 years old and under should be
properly restrained in a rear seating position whenever possible. See the
Child Safetychapter.

WARNING:If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. See your authorized dealer.
If the fuse is not blown and the brake lamps are working properly, the
following procedure allows you to move the gearshift lever from positionP:
1. Apply the parking brake, and
turn the engine off.
2. Remove the lower finish panel
below the steering column.
3. Turn the key to the on position,
but do not start the engine.
4. Pull back on the solenoid, and
at the same time, shift the
transmission into positionN.
5. Start the vehicle.
See your authorized dealer as
soon as possible if this
procedure is used.
Six–speed TorqShift® Transmission
WARNING:Always set the parking brake fully and make sure
the gearshift is latched in position P. Turn the ignition to the off
position and remove the key whenever you leave your vehicle.
WARNING:Do not use the tow/haul feature when driving in icy
or slippery conditions as the increased engine braking can cause
the rear wheels to slide and the vehicle to swing around with the
possible loss of vehicle control.

POWER TAKE-OFF (PTO) OPERATION (IF EQUIPPED)
A PTO unit allows the transmission to power auxiliary equipment to run
devices such as snowplows, aerial lifts, tow truck lifts, cement mixers or
dump trucks.
Vehicles Equipped with an Allison Automatic Transmission
(Except 3000 Series)
The PTO can be operated while the vehicle is standing or moving.
