Using this Manual
Please take the time to get acquainted with
your vehicle by reading this Operator’s
Manual. We recommend that you read and
understand this manual from beginning to
end before you operate this equipment.
This manual contains useful information for
the safe and efficient operation of this
equipment. It also provides service
information, with an outline for performing
safety checks and basic preventive
maintenance inspections. When
replacement parts are needed, we
recommend using only genuine PACCAR
parts.
We have tried to present the information
needed to learn about functions, controls,
and operation—and to present it as clearly
as possible. Occasionally, you may need to
reference this manual, and we hope you
find is easy to use.
NOTE
After you've read this manual, it should
be stored in the cab for convenient ref-
erence and remain with this truck
when sold.
Your vehicle may not have all the features
or options mentioned in this manual.
Therefore, you should pay careful attention
to the instructions that pertain to just your
vehicle. In addition, if your vehicle is
equipped with special equipment or options
not discussed in this manual, consult your
dealer or the manufacturer of the
equipment.
There are several tools built into this
manual to help you find what you need
quickly and easily; first is the Table of
Contents. Located at the front of the
manual, this table arranges the subject
matter into chapters, which can be quickly
referenced using the numbers shown in the
outer margin. The first page of each
chapter presents a list of the major
subjects contained in that chapter. Cross-
referenced citations can also help you find
information. If more information on the
current subject is located elsewhere in the
manual, a cross-reference may be
provided, such as "see Safety Alerts on
page 5." Finally, you’ll find a helpful
index at the back of the manual, which lists
the subjects covered, alphabetically.
All information contained in this manual is
based on the latest production information
available at the time of publication. If you
find differences between your instruments
and the information in this manual, contact
a PACCAR Powertrain distributor.
PACCAR reserves the right to make
changes at any time without notice.

understand all of the safety precautions
and warnings. The following is a list of
general safety precautions that must be
followed to provide personal safety. Failure
to follow these instructions may cause
death or injury. Special safety precautions

are included in the procedures when they
apply.
Keep in mind that even a well maintained
vehicle must be operated within the range
of its mechanical capabilities and the limits
of its load ratings. See the Weight Ratings
label on the driver's door edge.
Every new vehicle is designed to conform
to all Federal Motor Vehicle Safety
Standards applicable at the time of
manufacture. Even with these safety
features, continued safe and reliable
operation depends greatly upon regular
vehicle maintenance. Follow the
maintenance recommendations found in
the Preventive Maintenance section. This
will help preserve your investment.
Make sure your vehicle is in top working
condition before heading out on the road, it
is the responsible driver's duty to do so.
Inspect the vehicle according to the
Driver's Check List.
• Work areas should be dry, well lit,
well ventilated, free from clutter,
loose tools, parts, ignition sources
and hazardous substances.
• Wear protective glasses and
protective shoes when working.
• Wear protective gloves when
working with hot liquids or
surfaces.
• DO NOT wear loose-fitting or torn
clothing. Tie back and/or tuck in
long hair. Remove all jewelry when
working.
• Before beginning any repair,
disconnect the battery (negative [-]
cable) and discharge any
capacitors.
• Put a “DO NOT OPERATE” tag in
the operator's compartment or on
the controls.
• Allow the engine to cool before
slowly loosening the coolant fill cap
to relieve the pressure from the
cooling system.
WARNING
Removing the fill cap on a hot engine
can cause scalding coolant to spray
out and burn you badly. If the engine
has been in operation within the previ-
ous 30 minutes, be very careful in re-
moving the fill cap. Protect face,
hands, and arms against escaping flu-
id and steam by covering the cap with
a large, thick rag. DO NOT try to re-
move it until the surge tank cools down
or if you see any steam or coolant es-
caping. Always remove the cap very
slowly and carefully. Be ready to back
off if any steam or coolant begins to
escape. Failure to comply may result
in death, personal injury, equipment or
property damage.
• Always use wheel chocks or proper
jack stands to support the vehicle
or vehicle components before
performing any service work. DO
NOT work on anything that is
supported only by lifting jacks or a
hoist. Before resting a vehicle on
jack stands, be sure the stands are
rated for the load you will be
placing on them.
• Before removing or disconnecting
any lines, fittings, or related items,
relieve all pressure in the air, oil,
fuel, and cooling systems. Remain
alert for possible pressure when
disconnecting any device from a
system that contains pressure.
High-pressure oil or fuel can cause
death or personal injury.
• Always wear protective clothing
when working on any refrigerant
lines and make sure that the
workplace is well ventilated.

Inhalation of fumes can cause
death or personal injury. To protect
the environment, liquid refrigerant
systems must be properly emptied
and filled using equipment that
prevents the release of refrigerant
gas. Federal law requires capturing
and recycling refrigerant.
• When moving or lifting any heavy
equipment or parts, make sure to
use proper techniques and
assistance. Ensure all lifting
devices such as chains, hooks, or
slings are in good condition and
are of the correct load capacity.
Make sure all lifting devices are
positioned correctly.
• Corrosion inhibitors and lubricating
oils may contain alkali. DO NOT
get the substance in eyes and
avoid prolonged or repeated
contact with skin. DO NOT
swallow. If ingested, seek
immediate medical attention. DO
NOT induce vomiting. In case of
contact, immediately wash skin
with soap and water. In case of
harmful contact, immediately
contact a physician. Always keep
any chemicals OUT OF REACH
OF CHILDREN.
• Naphtha and Methyl Ethyl Ketone
(MEK) are flammable materials and
must be used with caution. Follow
the manufacturer's instructions to
ensure safety when using these
materials. Always keep any
chemicals OUT OF REACH OF
CHILDREN.
• When working on the vehicle, be
alert for hot parts on systems that
have just been turned off, exhaust
gas flow, and hot fluids in lines,
tubes, and compartments. Contact
with any hot surface may cause
burns.
• Always use tools that are in good
condition. Make sure you have the
proper understanding of how to use
the tools before performing any
service work. Use only genuine
replacement parts from PACCAR.
• Always use the same fastener part
number (or equivalent) when
replacing items. DO NOT use a
fastener of lesser quality if
replacements are necessary. (e.g.,
DO NOT replace an SAE 10.9
grade with 8.8 grade fastener.)
• Always torque fasteners and fuel
connections to the required
specifications. Overtightening or
under-tightening can allow leakage.
• Close the manual fuel valves prior
to performing maintenance and
repairs, and when storing the
vehicle inside.
• DO NOT perform any repair when
impaired, tired, fatigued, or after
consuming alcohol or drugs that
can impair your functioning.
• Some state and federal agencies in
the United States of America have
determined that used engine oil
can be carcinogenic and can cause
reproductive toxicity. Avoid
inhalation of vapors, ingestion, and
prolonged contact with used engine
oil.
• DO NOT connect the jump starting
or battery charging cables to any
ignition or governor control wiring.
This can cause electrical damage
to the ignition or governor.
• Coolant is toxic. If not reused,
dispose of coolant in accordance
with local environmental
regulations.
