General Safety Instructions
Important Safety Notice
WARNING!
Improper practices, carelessness,
or ignoring any warnings may cause
death, personal injury, equipment or
property damage.
Before performing any repair, read and
understand all of the safety precautions
and warnings. The following is alist 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.
• 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,
ventilated, free from clutter, loose
tools, parts, ignition sources and
hazardous substances.
• Wear protective glasses and
protective shoes when working.
• Do not wear loose-tting or torn
clothing. 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 ller
cap to relieve the pressure from
the cooling system.

Introduction
• Always use blocks or proper
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
ahoist.
• Before removing or disconnecting
any lines, ttings, 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 in awell ventilated
area. Inhalation of fumes can
cause death or personal injury.
To protect the environment,
liquid refrigerant systems must
be properly emptied and lled
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 any 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. In
case of contact, immediately wash
skin with soap and water. In case
of harmful contact, immediately
contact aphysician. Always keep
any chemicals OUT OF REACH
OF CHILDREN.
• Naptha and Methyl Ethyl Ketone
(MEK) are ammable 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 ow, and hot uids 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
afastener of lesser quality if
replacements are necessary.
• 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.
• Coolant is toxic. If not reused,
dispose of coolant in accordance
with local environmental
regulations.
• California Proposition 65 Warning
- Diesel engine exhaust and some
of its constituents are known to
the State of California to cause
cancer, birth defects, and other
reproductive harm.
• The catalyst substrate located
in the Diesel Particulate Filter
contains Vanadium Pentoxide.
Vanadium Pentoxide has been
determined by the State of
California to cause cancer. Always
wear protective clothing and eye
protection when handling the
catalyst assembly. Dispose of the
catalyst in accordance with local
regulations. If catalyst material
gets into the eyes, immediately
ood eyes with water for a
minimum of 15 minutes. Avoid
prolonged contact with skin. In
case of contact, immediately wash
skin with soap and water. In case
of harmful contact, immediately
contact aphysician.
CAUTION
Corrosive chemicals can damage
the engine. Do not use corrosive
chemicals on the engine. Failure to
comply may result in equipment or
property damage.

Red Warning Lamp on the oil
pressure gauge and the Stop
Engine Lamp will come ON.
CAUTION
Continuing to operate your vehi-
cle with insufcient oil pressure
may cause severe engine damage,
equipment or property damage.
• If the oil pressure fails to rise within
10 seconds after the engine starts,
stop the engine and determine the
cause.
• See Lubricating Oil System on
page 5-12, for the correct oil
pressure ranges for your vehicle's
engine. 6. Wait afew minutes to allow oil
to drain into the engine oil pan,
• If the oil pressure suddenly drops, and then check the oil level. (See
or the audible alarm and engine Inspection of the Engine Oil Level

and stop.
3. Place the transmission in
neutral and set the parking
brake. (See Parking Brake
Valve and OPERATING THE
TRANSMISSION in your
vehicle Operator's Manual,
for transmission shifting and
parking brake information.)

Check Engine Lamp Turns
On
Check Engine Lamp - Turns
on when aproblem exists, but
the vehicle can still be safely
driven. Vehicle should be
serviced to correct the problem
but the situation should not be
considered an emergency.
Engine is Overheating
CAUTION
The cooling system may overheat if
the engine coolant is at the minimum
level. Asudden loss of coolant,
caused by asplit hose or broken
hose clamp could also lead to an
overheat condition. Always inspect
to ensure hoses and clamps are not
cracked, worn, or loose. Failure to
comply may result in equipment or
property damage.
NOTE
The system may also temporarily
overheat during severe operating
conditions such as:
• Climbing ahill on ahot day.
• Stopping after high-speed/high-
load driving.
• Debris blocking air ow through
the cooling module (radiator).
If the engine coolant temperature
warning lamp comes on and the
audible alarm sounds showing an
overheat condition, or if you have any
other reason to suspect the engine
may be overheating, DO NOT TURN
OFF THE ENGINE unless alow water
warning device indicates aloss of
coolant. Follow these steps:
• Reduce engine speed or stop.
When stopped, place the
transmission in neutral and set the
parking brake. See the vehicle
operator's manual for instructions
on transmission shifting and
parking brake information.
• Check to ensure that the oil
pressure gauge reads normal.
• Increase the engine speed to
1,100 to 1,200 rpm maximum for
2-3 minutes.

• Monitor the engine temperature.
After the temperature returns to
normal, allow the engine to idle
3–5 minutes before shutting it off.
This allows the engine to cool
gradually and uniformly.
• If the overheating came from
severe operating conditions, the
temperature should have cooled
by this time.
• Check the coolant level at the
cooling module surge tank.
WARNING! WARNING!
To reduce the chance of personal in-
jury and/or vehicle damage caused
by engine overheating, never leave
the engine idling when the vehicle is
unattended. If the engine overheats,
immediate action is required to cor-
rect the condition. Continued unat-
tended operation of the engine, even
for ashort time, may result in seri-
ous engine damage or are. Failure
to comply may result in death, per-
sonal injury, equipment or property
damage.
Removing the ll cap on ahot en-
gine can cause scalding coolant
to spray out and burn you badly.
If the engine has been in opera-
tion within the previous 30 minutes,
be very careful in removing the ll
cap. Protect face, hands, and arms
against escaping uid and steam by
covering the cap with alarge, thick
rag. Do not try to remove it until
the surge tank cools down or if you
see any steam or coolant escaping.
In any situation, remove the cap
very slowly and carefully. Be ready
to back off if any steam or coolant
begins to escape. See the vehicle
operator's manual for instructions
on checking and lling the cooling
module surge tank.
