MODEL 330 OPERATOR'S MANUAL - Peterbilt Motors Company

Preventive Maintenance
CAUTION: Applying a higher voltage booster
battery will cause expensive damage to sensitive
electronic components, such as relays, and
the radio.
• Improper hook-up of jumper cables or not following
these procedures can damage the alternator or
cause serious damage to both vehicles.
WARNING! To avoid serious personal injury and
damage to the vehicle, heed all warnings 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 going further. If
the level is low, add distilled water and replace the caps
before proceeding. If no water is available, remove the caps
and cover the filler openings with a cloth. After jump starting
the vehicle, dispose of the cloth.
Electrical System
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.

1. Position the two vehicles together, but do not let them to
touch.
2. Turn OFF all lights, heater, radio, and any other accessory.
3. Set the parking brakes: pull out the Yellow button
located on the dash.

WARNING! When connecting jumper cables,
make sure they can not get caught in any moving
parts in the engine compartment. You could
be seriously injured.
