Safety - Introduction
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. We have tried to
present the information you’ll need to learn
about functions, controls, and operation—
and to present it as clearly as possible. We
hope you’ll find this manual easy to use.
There will be times when you need to take
this manual out of the glovebox. When you
do, please be sure to return it when you
are finished using it. That way it will be
there when you need it the next time or
when you pass the vehicle on to the next
user.
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 Quick Table
of Contents. Located at the front of the
manual, this lists the main subjects
covered and gives section numbers where
you can find these subjects. Use the Quick
Table of Contents to find information on a
large subject like “Maintenance.” Cross-
referenced citations also help you get the
information you need. If some other part of
the manual contains further information on
the subject you are reading about, we’ll
indicate that in a cross-reference like this:
(See Safety Alerts on page 5). You won’t
have to go searching for more information.
Finally you’ll find a helpful Subject Index.
It’s in the back of the manual and
alphabetically lists the subjects covered.
So if you want information on brakes, for
example, just look under Brake in the
Subject Index. You’ll find all the pages
listed where brakes or braking are
discussed.
All information contained in this manual is
based on the latest production information
available at the time of publication.

Improper practices, carelessness, or
ignoring any warnings may cause
death, personal injury, equipment or

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
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.
• Use the proper tool for manually
rotating the engine. DO NOT
attempt to rotate the crankshaft by
pulling or prying on the fan. This
practice can cause death, personal
injury, equipment damage, or
damage to the fan blades, causing
premature fan failure.
•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.
• DO NOT wear loose-fitting or torn
clothing. Tie back and/or tuck in
long hair. Remove all jewelry when

• 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 filler
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. In any situation, remove the
cap very slowly and carefully. Be ready
to back off if any steam or coolant be-
gins to escape.
• 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.
• Naptha 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.
