This Operator’s Manual contains useful information for the safe and efficient operation of your Peterbilt Model 330, Medium–duty vehicle. It also provides information on maintaining your vehicle in the best condition, with an outline for performing safety checks and basic preventive maintenance inspections.
Your Model 330 may not have all the features or options men- tioned 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.
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 with the equipment and trained personnel to quickly get 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 qualifications, then you can probably perform some repairs yourself. But if you are not an experienced mechanic, or do 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.
