PREVENTIVE MAINTENANCE
INTRODUCTION
This section will help you keep your Medium Duty vehicle in
good running condition. There are a number of checks you
can do, and you may be able to do some of the service work
yourself. But please, let your Peterbilt Dealer or Authorized
Service Center do any work you do not have the tools or skill
to perform. Authorized service mechanics are trained in the
proper technical and safety procedures to maintain your
Medium Duty vehicle correctly.
Good driving practices, daily and weekly driver maintenance
inspections, and periodic service inspections by an Authorized
Service Center, will help keep your Medium Duty vehicle
in good working order and provide many years of
dependable service.
WARNING! It is dangerous to work on a vehicle
without the right know-how and proper tools.
You could be killed or seriously injured, cause
damage to the vehicle, or make your vehicle
unsafe to drive. Do only work you know you are
fully able to do, and for which you have the right
tools.
•Before attempting any procedures in the engine
compartment, stop the engine and let it cool
down. Hot components can burn skin on contact.
•Be alert and cautious around the engine at all
times while the engine is running.
•If work has to be done with the engine running,
always (1) set the parking brake, (2) chock the
wheels, and (3) ensure that the shift lever or
selector is in Neutral.
•Exercise extreme caution to prevent neckties,
jewelry, long hair, or loose clothing from getting
caught in the fan blades or any other moving
engine parts.
