A Special Word About Repairs
This is not a repair or workshop manual. Your Peterbilt
Dealer’s Service Center is the best place to have your Model
330 repaired. You can find Peterbilt dealers all over the country wit h the equ ipmen t and train ed per sonne l to quickly ge t
you back on the road—and to keep you there.
Your Model 330 is a complex machine. Anyone attempting
repairs on it needs good mechanical training, proper specifications, and proper tools. If you are sure you meet these
qualific ations, the n you can prob ably per form some r epairs
yourself. But if you are no t an exper i ence d m echa nic, or d o
not have the right equipment or training, please leave the
repairs to an authorized service facility. They are the ones
equipped to do the job safely and correctly.
WARNING! Do not attempt repair work without
sufficient training, service manuals, and the
proper tools. Yo u could be injur ed, or you could
make your vehicle unsafe. Do only those tasks
you are fully qualified to do.
Shop Ma nuals
If you do decide to do complex r epair work, you will need the

START–UP
Introduction
The following section covers star t -up proced ure s for getti ng
your Model 330 ready for the road.
Door Lock and Keys
Doors can be locked from the inside by using the lock button.
Close the door then push the button down to lock. Doors
automat ica lly unlo ck wh en you open t he m fr om insi de, an d
can be locked from the outside with the key only.
As standard equipment, two keys are provided for the doors
and ignition. When necessary, additional locks and keys are
provided for storage compartments.
Model 330 PB1318 3/01
To lock or unlock the doors from outside the cab:
• Insert the key in the door lock.
• Turn the key toward the rear door frame to lock; forward
Cab and Frame Access
The following cab and frame entry/exit procedur e recommendations were prepared with personal saf ety f or emost in mind.
WARNING! To help lessen the chance and/or
severity of pers onal in jury in case of an acc ident, always lock the doors while driving. Along
with using the lap s houl der belt s prope rly, locking the doors helps prevent occupants from
being thrown from the vehicle.
to unlock.
WARNING! Do not jump out of the cab or get into
the cab without proper caution. You could slip or
fall, possibly suffering a serious injury. You
could slip and fall if the steps are wet or icy, or if
you step in fuel, oil, or grease.
– 7 –
Start–Up Operating Instructions
To help avoid personal injury due to a slip or fall:
• Use three points of contact (two feet, one hand or one
foot, two hands) to g rip the steps or handholds whene ver
possible and look where you are going.
02611
• Use even more care when steps and handholds (or footwear) are wet, coated with ice, snow, mud, oil, fuel, or
grease.
WARNING! Do not step on vehicle components
without antiskid sur faces or use component s
not designed for entry-and-exit use. You could
fall and injure yourself if you step onto a slippery
surface. For example:
• Do not step onto the surface of a fuel tank. A fuel
tank is not a step. The tank surface can get very slippery, and you might not be able to prevent a fall. Use
only the steps and handholds provided, not chain
hooks, quarter fenders, etc.
• Do not climb onto and off the deck p late—use steps
and grab han dle prov ided. If there is no deck pla te,
or if proper steps and grab handles are not provided,
do not climb onto the area behind the cab.
• Keep steps clean. Clean any fuel, oil, or grease off
the ste ps b efore enter ing the cab or acce ssi ng th e
deck plate.
WARNING! Always reinstall the battery compartment cover (step) before entering the cab. With out the battery cover you could slip and fall,
resulting in possible injury to yourself.
NOTE: Any alteration (adding bulkheads, headache
racks, tool boxes, etc.) behind the cab that affects
the utilization of grab handles, deck plates, or frame
access steps installed by Peterbilt should comply
with Federal Motor Carr ier Safety Regulation 399.

Safe Vehicle Operation
For your safety, as well as those around you, be a responsible driver:
• If you drink, do not drive.
• Do not drive if y ou ar e t ired, ill, or under emotional stress.
Much has gone into the manufacturing of your Model 330,
including advanced engineering techniques, rigid quality control, and dem and ing in spec tio ns. The se m anu factur ing p ro cesses will be enhanced by you—the safe driver—who:
– 10 –
PB1318 3/01 Model 330
Operating Instructions Start–Up
• knows and understands how to operate the vehicle and
all its controls
• maintains the vehicle properly
• uses driving skills wisely
For more information, re fer to De par tme nt o f Transportation
Regulation 392.7, which states that interstate commercial
motor vehicles are not to be dr iven unless the driver is sur e
that certain parts and accessories are in working order.
WARNING! Do not drink and drive. Y our refle xes,
perceptions, and judgment can be affected by
even a small amount of alcoh ol. You could have
a serious—even fatal—accident if you drive after
drinking. Please do not drink and drive or ride
with a driver who’s been drinking.
• The use of alcohol, dru gs, and certain medications
will seriously impair perception, reactions, and driving ability. These circumstances can substantially
increase the risk of an acc iden t and ser ious p ersonal injury.
Vehicle Loading
Compare your vehicle’s load capacity wit h the total load you
are carrying. If ad justments ne ed to be made, m ake them—
do not drive an overloaded vehicle. I f you are overloaded or
your load has shifted, your vehicle may be unsafe to drive.
WARNING! Do not exceed the specified load rating. Ove rload ing can res ult in loss of v ehicle
control and serious persona l inju ry, either by
causing component failures or by affecting vehicle handling. Exceeding load ratings can also
shorten the service life of the vehicle.
• The components of your vehicle are designed to provide satisfacto ry ser v ice if t he v ehicle is no t l oade d
in excess of either the gross vehicle weight rating
(GVWR), or the maximum front and rear gross axle
weight r atings (GAWRs). (Axle weight rati ngs are
listed on the driver's door edge.)
Here are some definitions of weight you should know:

WARNING! An unevenly distributed load or a
load too heavy over one axle can affect the braking and handling of your vehicle, which could
result in an accid ent . Even if your load i s un der
the legal limits, be sure it is distributed evenly.
Emergency Equipment
It is good practice to carry an emergency equipment kit in
your vehi cle . One da y, if you ha v e a roadside emergency, you
will be glad the following items are with you:
• window scraper
• snow brush
• container or bag of sand or salt
• emergency light
•small shovel
• first aid kit
• fire extinguisher
Driver’s Check List
To keep your Model 330 in top shape and maintain a high
level of safety for you, your passengers, and your load, make
a thorough inspection every day before you drive. You will
save maintenance time later, and the safety checks could
help prevent a serious accident. Please r emember, too, that
the Federal law requires a pre-trip inspection and so do commercial trucking companies.
You are not expected to become a professional mechanic.
The purpose of your inspections is to find anything that might
interfere with the safe and efficient transportation of yourself,
any passengers, and your load. If you do find som ething
wrong and cannot fix it yourself, have an Authorized Service
Center or qualified mechanic repair your vehicle right away.
