Regional Haul Model Operator's Manual - Peterbilt Motors Company

PREVENTIVE MAINTENANCE
• Disconnect the battery ground strap whenever
you work on the fuel system or the
electrical system. When you work around
fuel, do not smoke or work near heaters or
other fire hazard. Keep an approved fire
extinguisher handy.
• Always support the vehicle with appropriate
safety stands if it is necessary to work
underneath the vehicle. A jack is not adequate
for this purpose.
• When working underneath the vehicle without
appropriate safety stands but with the
wheels on the ground (not supported),
make sure that (1) the vehicle is on hard
level ground, (2) the parking brake is
applied, (3) all wheels are chocked (front
and rear) and (4) the engine cannot be
started. Remove the ignition key.
• Never start or let the engine run in an
enclosed, unventilated area. Exhaust fumes
from the engine contain carbon monoxide,
a colorless and odorless gas. Carbon monoxide
can be fatal if inhaled.
INTRODUCTION
Incomplete or improper servicing may cause problems in
the operation of the vehicle. If in doubt about any servicing,
have it done by your Authorized Service Center.
Improper maintenance during the warranty period may
also affect the warranty coverage.
Modifying your vehicle can make it unsafe. Some modifications
can affect your vehicle's electrical system, stability,
or other important functions. Before modifying your
vehicle, check with your Peterbilt Dealer to make sure it
can be done safely and correctly.
