OPERATING INSTRUCTIONS

START–UP

Introduction

The following section covers start-up procedures for getting 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 automatically unlock when you open them from inside, and 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.

WARNING! To help lessen the chance and/or severity of personal injury in case of an accident, always lock the doors while driving. Along with using the lap shoulder belts properly, locking the doors helps prevent occupants from being thrown from the vehicle.

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 to unlock.

Cab and Frame Access

The following cab and frame entry/exit procedure recommendations were prepared with personal safety foremost in mind.

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.

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 grip the steps or handholds whenever 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 surfaces or use components 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 plate—use steps and grab handle provided. If there is no deck plate, 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 steps before entering the cab or accessing the deck plate.

WARNING! Always reinstall the battery compartment cover (step) before entering the cab. Without 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 Carrier 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 you are tired, ill, or under emotional stress.

Much has gone into the manufacturing of your Model 330, including advanced engineering techniques, rigid quality control, and demanding inspections. These manufacturing processes 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, refer to Department of Transportation Regulation 392.7, which states that interstate commercial motor vehicles are not to be driven unless the driver is sure that certain parts and accessories are in working order.

WARNING! Do not drink and drive. Your reflexes, perceptions, and judgment can be affected by even a small amount of alcohol. 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, drugs, and certain medications will seriously impair perception, reactions, and driving ability. These circumstances can substantially increase the risk of an accident and serious personal injury.

Vehicle Loading

Compare your vehicle’s load capacity with the total load you are carrying. If adjustments need to be made, make them— do not drive an overloaded vehicle. If you are overloaded or your load has shifted, your vehicle may be unsafe to drive.

WARNING! Do not exceed the specified load rating. Overloading can result in loss of vehicle control and serious personal injury, 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 satisfactory service if the vehicle is not loaded in excess of either the gross vehicle weight rating (GVWR), or the maximum front and rear gross axle weight ratings (GAWRs). (Axle weight ratings are listed on the driver's door edge.)

Here are some definitions of weight you should know:

GVWR: is the Gross Vehicle Weight Rating. This is the MAXIMUM WEIGHT your vehicle is allowed to carry, including the weight of the empty vehicle, loading platform, occupants, fuel, and any load. Never exceed the GVWR of your vehicle.

Model 330

PB1318 3/01

– 11 –

Start–Up

Operating Instructions

GCW: is the actual combined weight, or Gross Combination Weight (GCW), of your vehicle and its load: tractor, plus trailer(s), plus cargo.

GAWR: is the Gross Axle Weight Rating. This is the total weight that one axle is designed to transmit to the ground. You will find this number listed on the driver’s door edge.

Load Distribution: be sure any load you carry is distributed so that no axle has to support more than its GAWR.

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 accident. Even if your load is under the legal limits, be sure it is distributed evenly.

Emergency Equipment

It is good practice to carry an emergency equipment kit in your vehicle. One day, if you have 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 remember, 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 something wrong and cannot fix it yourself, have an Authorized Service Center or qualified mechanic repair your vehicle right away.
