Safety Precautions
– 1 –
GENERAL
Safety Precautions
The following list of safety
precautions against possi-
ble safety hazards is not
exhaustive and, therefore all
safety related workshop
practices and precautions
must be exercised.
General
Ensure all Warnings and Cautions
listed in this publication are strictly
adhered to. Always read carefully the
instructions printed on labels or
stamped on components and obey
them completely. Such instructions are
included for your health and safety; do
not disregard them.
Wear clean protective clothing or appa-
ratus when necessary.
Engine
Do not run engine in a confined space
or unventilated area or with a leaky
exhaust system. If the engine must be
run in a confined space ensure that an
exhaust extractor is used.
To prevent a possible fire risk, ensure
that the engine and its surrounding
areas are clean and free from leakages/
spillages of any inflammable liquids
(e.g. fuel oil, engine oil, etc.).
Cooling System
Do not attempt to remove the surge
tank filler cap while the engine is run-
ning or still hot.
Do not attempt to fill a hot engine with
cold coolant.
Do not fill the cooling system through
the pressure cap aperture.
PB1340A.book Page 1 Friday, September 1, 2000 7:40 AM

Safety Precautions General
– 2 –
Components
Ensure that all personnel are clear of
any rotating parts or moving compo-
nents.
Synthetic rubber seals, O-rings and
gaskets which have been damaged by
fire or come into contact with direct
heat, may produce hazardous fumes
and highly corrosive chemicals.
Allow burnt or decomposed seals etc.
to completely cool. Use impervious pro-
tective clothing and gloves. Work in a
well ventilated area when handling
these components. In the event of
skin contact seek medical attention
immediately.
Electrical
Batteries contain electrolyte (sulfuric
acid) which is a highly corrosive and
toxic substance. Accidental skin/eye
contact with battery electrolyte can
cause serious personal injury.
Always wear protective clothing and
suitable eye protection when handling
batteries and wash hands after use.
WARNING! Battery posts,
terminals and related acces-
sories contain lead and lead
compounds, chemicals
known to the State of Cali-
fornia to cause cancer and
reproductive harm. Wash
hands after handling.
Always disconnect the batteries before
commencing work on the vehicle. To
minimize the risk of accidental short cir-
cuits when disconnecting the batteries,
ensure that the negative (–) lead is dis-
connected first and the positive (+)
lead last; reverse this procedure when
re-connecting the batteries.
To prevent accidental short circuits do
not place tools/metal objects on or near
the battery terminals.
Batteries produce a highly flammable
and explosive gas while being charged.
It is essential that the area around the
battery is well ventilated and protected
against any flame, spark or intense
heat source. The use of
“boost” charg-
ers is not recommended.
The ignition switch, steering lock, and
its electrical circuits are designed to
prevent the auxiliary circuits and starter
motor from being energized while the
steering lock is engaged. Serious con-
sequences could result from alteration
or substitution of the ignition switch and
PB1340A.book Page 2 Friday, September 1, 2000 7:40 AM

Safety Precautions General
– 3 –
steering lock or its wiring. Under no cir-
cumstances must the ignition switch be
separated from the steering lock.
Oils and Lubricants
Many liquids and other substances
used in commercial vehicles are highly
toxic. These must not be consumed or
inhaled and, as far as possible, must be
kept from skin contact. These sub-
stances, amongst others, include bat-
tery acid, anti-freeze, hydraulic fluid,
lubricants, fuel, windshield washer fluid,
refrigerant, and various adhesives.
Avoid unnecessary contact with used
engine oil. Prolonged and repeated
contact with used engine oil may cause
serious skin disorders.
Extreme care must be taken when
draining engine oil; hot engine oil can
cause severe personal injury.
Maintenance Activities
Do not use the jack as the sole means
of support; position suitable supports
beneath the chassis frame.
Do not attempt to work on the vehicle
with the cab partially tilted.
Do not attempt to stand on the cab roof.
Chassis Frame
Do not weld or subject the chassis
frame to a severe localized heat source.
Failure to observe this precaution may
result in irreparable damage to the
material structure of the chassis frame
with consequent loss in chassis frame
strength.
Welding or drilling on the chassis frame
must not be undertaken without the
prior written consent of PACCAR Inc.
Unauthorized, indiscriminate welding or
drilling may adversely affect the safe
load-carrying characteristics of the
chassis frame.
Welding
• Observe these recommended pro-
cedures to protect electronic sys-
tems during welding operations.
All Electronic Engines
Before welding on vehicles equipped
with electronic engines, the following
precautions should be observed:
NOTE: Welding to frame rail
may void frame rail warranty.
• Turn engine OFF.
• Disconnect all electronic connec-
tions to the vehicle batteries.
• Remove battery power cable and
insulate it from the vehicle.
PB1340A.book Page 3 Friday, September 1, 2000 7:40 AM

Safety Precautions General
– 4 –
• Disconnect all Electronic Control
Module (ECM) connectors (on
electronic engines).
• Do not use the ECM or engine
ground stud for the ground of the
welding probe.
• Ensure that the ground connection
for the welder is as close to the
weld point as possible. This
ensures maximum weld current
and minimum risk to damage of
electrical components on the vehi-
cle.
All Anti–Lock Braking Systems
(ABS)
Before welding anywhere on the vehi-
cle, detach the ABS Electronic Control
Unit (ECU) connector and all other
electronic control units.
Vehicle Load
The load must always be properly
secured so that it cannot move while
the vehicle is in motion, even during an
emergency stop. Side walls, partitions,
headboards, etc., are not designed to
withstand high forces. Loads must not
project more than is permitted by local
or national regulations. The stability of
the vehicle may be impaired by the load
and an increased turning circle may be
required.
Fire Extinguisher
Ensure that you always have a fire
extinguisher with you. It should be well
secured within hand’s reach of the
driver and easily accessible for rescue
workers and others providing assis-
tance. Have the fire extinguisher
checked for operational readiness as
recommended by the manufacturer.
When it has been used, have it refilled
at the earliest opportunity.
First Aid Kit
Make sure that you always have a first
aid kit with you. Replenish the contents
as soon as possible after use.
Winter Driving Conditions
When winter driving conditions are
expected, ensure that your vehicle is
prepared in accordance with the recom-
mendations in “Preventive Maintenance
Before the Winter Season” on page 88.
When severe winter driving conditions
are anticipated, ensure that your vehi-
cle is fitted with winter tires or that you
have snow equipment, as allowed by
state law.
PB1340A.book Page 4 Friday, September 1, 2000 7:40 AM

Items of Special Importance General
– 5 –
Items of Special
Importance
To prevent damage to the vehicle,
the following instructions must be
strictly observed.
Break-in
The following “break-in” recommenda-
tions should be applied during the first
1,000 miles (1,600 km) of a new vehi-
cle:
•Donot operate at full engine power
in any gear.
•Donot allow the engine to labor in
any gear.
•Donot allow the engine to run at
idling speeds for excessive periods.
During the “break-in” period do not
subject the new vehicle to excessive
loads; this also applies when an over-
hauled engine, transmission, or differ-
ential has been installed.
After a cold start continue to drive in a
low gear and at a moderate engine
speed until the engine coolant tempera-
ture has reached 140°F (60°C).
Check the instrument panel regularly
when driving and take immediate steps
to rectify possible problems at the first
sign of trouble.
Do not let the engine idle for longer
than necessary. This is harmful for the
engine and also causes unnecessary
pollution of the environment.
CAUTION: In the event of the
engine stalling while the
vehicle is in motion, power
assistance to the steering will be lost
and, consequently, greater effort will
be required to steer the vehicle.
The engine turbocharger is a preci-
sion instrument. For this reason the fol-
lowing operating procedures should be
observed:
• When starting the engine, do not
allow it to exceed its idling speed
for 10 seconds; this procedure will
ensure that adequate oil pressure
is available at the turbocharger
bearings thus preventing initial oil
starvation.
PB1340A.book Page 5 Friday, September 1, 2000 7:40 AM

Items of Special Importance General
– 6 –
• Before stopping the engine, allow it
to idle for one to two minutes (par-
ticularly if the engine has been sub-
jected to a high speed journey or
high engine loadings). This proce-
dure will ensure an adequate oil
supply to the turbocharger bear-
ings while the rotor assembly is
cooling, thus improving the life
span of the turbocharger bearings.
• Any abnormal noises or vibrations
from the turbocharger must be
reported immediately.
Cooling System
CAUTION: Damage to the
engine and cooling system,
such as corrosion and cavi-
tation erosion, will occur unless anti-
freeze ZEREX PENRAY 2792 is used
and maintained with supplemental
coolant additive Pencool 3000 with
Stabil-Aid. As needed, fill or top off
the cooling system only with a
ready-mixed clean water/approved
antifreeze solution using these prod-
ucts. The use of other antifreeze
products will void your engine, radi-
ator, and cooling system warranties.
The engine cooling system is thermo-
statically controlled, so the use of a
radiator cover in cold weather is
unnecessary.
Air Leakage
If the pressure in the air reservoirs
drops rapidly with the engine switched
off, this indicates a leak in the com-
pressed air system. Since this affects
the safety of the brake system, the leak
must be traced and repaired as quickly
as possible.
System Voltage
The vehicle is equipped with a 12 volt
negative ground electrical system.
When replacing or fitting electrical or
electronic components, always verify
that they are suitable for this system
voltage, polarity, and capacity.
Batteries
Do not disconnect the battery terminals
while the engine is running; failure to
observe this precaution may result in
major damage to the alternator.
Serious battery damage and vehicle
starting difficulties will occur if the bat-
teries are discharged (“drained”) below
12 volts. To prevent the batteries from
being inadvertently discharged, it is
essential the following precautions are
observed:
PB1340A.book Page 6 Friday, September 1, 2000 7:40 AM

Items of Special Importance General
– 7 –
• Ensure that all lights are switched
off when not required.
•
Vehicles fitted with a liftgate: Avoid
excessive and severe battery drain
when operating the liftgate.
Battery Charging
WARNING! Battery posts,
terminals and related acces-
sories contain lead and lead
compounds, chemicals
known to the State of Cali-
fornia to cause cancer and
reproductive harm. Wash
hands after handling.
WARNING! Do not try to
charge a frozen battery.
(Even a battery with ice par-
ticles on the electrolyte sur-
face is dangerous.) Allow it
to thaw out first. And always
allow the battery to thaw
gradually—do not apply
direct heat. Gas trapped in
the ice may cause an explo-
sion.
First connect the positive (+) terminal of
the battery charger to the positive (+)
terminal post of the battery and then
the negative (–) terminal to the negative
(–) terminal post. After charging, switch
off the battery charger and then discon-
nect the negative (–) terminal followed
by the positive (+) terminal. For normal
charging, the battery cables may
remain in place. For fast-charging, both
battery cables must be disconnected.
Jump Starting Vehicles
It is not recommended that you attempt
to jump start your vehicle. If you have a
battery problem, it is best to contact a
dealer or a reputable towing service.
However, if your battery is discharged
(dead), you may be able to start it by
using energy from a good battery in
another vehicle. This is termed “jump
starting.” Be sure to follow the precau-
tions and instructions below.
WARNING! Batteries can
injure you severely. They
contain acid, produce poi-
sonous and explosive
gases, and supply levels of
electric current high enough
to cause burns. A spark or
flame near a battery on
charge may cause it to
explode with great force.
PB1340A.book Page 7 Friday, September 1, 2000 7:40 AM

Items of Special Importance General
– 8 –
WARNING! Do not allow bat-
tery fluid to contact eyes,
skin, fabrics, or painted sur-
faces. Always wear eye pro-
tection. Battery acid that
may spill during charging
should be washed off with a
solution of warm water and
baking soda to neutralize
the acid. If you accidentally
get acid in your eyes or on
your skin, immediately rinse
with cold water for several
minutes and call a doctor.
• Be careful that metal tools (or
any metal in contact with the
positive terminal) do not contact
the positive battery terminal and
any other metal on the vehicle at
the same time. Remove metal
jewelry and avoid leaning over
the battery.
• If metal jewelry or other metal
comes in contact with electrical
circuits, a short circuit may
occur causing you to be injured,
as well as electrical system fail-
ure and damage to the vehicle.
• If the level of electrolyte is low, add
distilled water and replace the bat-
tery caps before proceeding. If no
water is available, remove the bat-
tery caps and cover the filler open-
ings with a cloth before proceeding.
After jump starting the vehicle, dis-
pose of the cloth.
To Jump Start Your Vehicle
WARNING! The voltage of
the booster battery must
have a 12–volt rating. And
the capacity of the booster
battery should not be lower
than that of the discharged
battery. Use of batteries of
different voltage or substan-
tially different capacity rat-
ing may cause an explosion
and personal injury.
CAUTION: Applying a higher
voltage booster battery will
cause expensive damage to
sensitive electronic compo-
nents, such as relays, and
the radio.
• Improper hook-up of jumper
cables or not following these
procedures can damage the
alternator or cause serious dam-
age to both vehicles.
WARNING! To avoid serious
personal injury and damage
to the vehicle, heed all warn-
ings and instructions of the
jumper cable manufacturer.
• The jumper cables must be long
enough so that the vehicles do
not touch.
If either battery has vent caps, remove
them and check the fluid level. If it is
OK, replace the caps before proceed-
ing. If no water is available, remove the
PB1340A.book Page 8 Friday, September 1, 2000 7:40 AM

Items of Special Importance General
– 9 –
caps and cover the filler openings with
a cloth before proceeding. After jump
starting the vehicle, dispose of the
cloth.
WARNING! If you do not
cover the filler openings on
the battery, electrolyte could
boil out of the openings and
hurt someone or damage the
vehicle. Replace caps
securely if the battery has
the full level of electrolyte. If
the electrolyte is low and no
water is available, cover with
a cloth.
Preparing the vehicles:
1. Position the two vehicles together,
but do not let them touch.
2. Turn OFF all lights, heater, radio,
and any other accessories.
3. Set the parking brakes.
4. Ensure that the transmission is in
neutral position or, if auto shift, that
it is in park position.
5. Turn engine OFF (booster vehicle).
6. Disconnect ground cable on
booster battery.
Connect the batteries:
1. Attach one end of a jumper cable to
the positive terminal of the dis-
charged (dead) battery. This will
have a large red “+” or “P” on the
battery case, post, or clamp.
• Attach the other end of the
same cable to the positive (+)
terminal of the good (booster)
battery.
• Attach the remaining jumper
cable FIRST to the negative
terminal (black “–” or “N”) of
the good battery.
• Attach the other end of the
negative cable to a bare metal
part bolted to the engine block
(of the vehicle with the dead
battery) or, if possible, clamp
directly to the engine block.
IMPORTANT: Always connect posi-
tive (+) to positive (+) and negative
(–) to negative (–).
2. Start the engine:
• Start the vehicle that has the
good battery first. Let it run for
a few minutes.
• Then start the vehicle that has
the discharged (dead) battery.
If the engine fails to start, do not
continue to crank the starter.
Contact the nearest Authorized
Service Center.

Remove jumper cables:
WARNING! When discon-
necting jumper cables, make
sure they do not get caught
in any moving parts in the
engine compartment. You
could be seriously injured.
• Reverse the above procedure
exactly when removing the jumper
cables. With engine running, dis-
connect jumper cables from both
vehicles in the exact reverse order
(Steps 4 – 1), making sure to first
remove the negative cable from the
vehicle with the discharged battery.
Protecting the
Environment
The growing scarcity of the world's nat-
ural resources and the escalating prob-
lem of pollution pose serious threats to
the environment. In order to conserve
resources and to minimize pollution it is
recommended that the following prac-
tices are adopted:
• Do not dispose of used oils,
hydraulic fluids, or engine coolant
in drains, sewers, water courses, or
land-fill sites. These fluids are
harmful to the environment and
must be disposed of properly.
• Used oils, coolant, and hydraulic
fluids should be returned to the
appropriate authority for recycling.
Ensure that all waste fluid products
are segregated and are not inter-
mixed; this practice will increase
the efficiency and viability of the re-
cycling process.
• Ensure that the vehicle is regularly
serviced to maintain peak effi-
ciency. A correctly maintained vehi-
cle will contribute to maximum fuel
economy and a reduction in
exhaust gas pollutants.

Cleaning the Vehicle General
– 11 –
Cleaning the Vehicle
Before cleaning the vehicle, check for
evidence of leakage around the engine,
axles, transmission, etc., because this
will not be possible when carrying out
service operations after the vehicle has
been cleaned.
When a high-pressure cleaner is used,
takespecial note of the following points:
• Ensure that all doors, windows, and
cab grille are correctly closed.
• Do not spray directly on seals.
There is a danger of the seals
being forced open by the high-pres-
sure jet of water so that the grease
packed behind them is flushed
away.
• The hydraulic fluid reservoir for the
steering gear is provided with a
ventilation opening. Water may
enter the reservoir through this
opening and damage the steering
gear.
• When cleaning the radiator/inter-
cooler, take care not to damage the
ribs or fins of the cores.
• Make sure that no water can enter
the differential or transmission via
the ventilation openings.
• Ensure that no water is allowed to
enter the clutch fluid reservoir via
the ventilation opening.
• The engine and engine compart-
ment may be cleaned with a high-
pressure cleaner. However, do not
aim the jet of water directly at elec-
trical components such as the
starter motor, alternator, etc.
• Do not aim the jet of water directly
at electrical connections such as
connectors, cable feed-through for
the vehicle lighting, etc.
• When cleaning the vehicle, make
sure that no water enters the air
intake system via the air inlet or its
flexible joints.
CAUTION: After steam
cleaning the vehicle, it is
essential that all grease
points are lubricated with a
grease gun or with the auto-
matic chassis lubrication
system to prevent moisture
and dirt from entering the
various pivot points.
PB1340A.book Page 11 Friday, September 1, 2000 7:40 AM

Cleaning the Vehicle General
– 12 –
Cleaning the Cab
The external paintwork of the cab is
subject to attack by aggressive sub-
stances, the severity of which depends
upon the specific transport role and
operating conditions of the vehicle, for
example salt scattered on icy roads,
and air pollution. The paintwork must
therefore be cleaned regularly.
When cleaning the cab, make sure that:
• no aggressive cleaners are used;
• no stiff brushes are used;
• all seams, gaps, and door frames
are thoroughly cleaned.
Waxing the Cab
To maintain and protect the cab paint-
work, it is recommended that a coating
of wax is applied at least twice a year.
Your dealer can advise you about addi-
tional anti-rust treatment and mainte-
nance of the paintwork when the
vehicle is in service.
Cleaning the Cab Interior
Clean the carpets and seats with a
brush or vacuum cleaner and occasion-
ally with diluted upholstery cleaner; do
not attempt to “dry clean” the carpets
or seats.
Clean vinyl faced upholstery and paint-
work with a mild household detergent;
do not use harsh abrasives or solvent-
based cleaning solutions.
NOTE: The appearance of
your vehicle is the calling card
of your company!
