(Inspection Guide)
Introduction
Warning
To prevent property damage, personal
injury, and/or death, when servicing the
vehicle, park on a flat level surface, set
the parking brake, turn the engine off,
and install wheel chocks.
Warning
To prevent property damage, personal
injury, and/or death, have a qualified
technician regularly check operation of
transmission neutral start switch. If unit
starts in gear, the vehicle may
inadvertently move.
To be sure your vehicle is ready to operate,
conduct a pre-trip inspection at the
beginning of each work period. This section
gives the operator suggested guidelines to
be used in performing tractor and trailer
pre-trip inspections. Safety is the most
important and obvious reason for doing a
pre-trip inspection. Depending on the
optional features of the vehicle being used
and any possible aftermarket items installed
on the vehicle, these guidelines should be
modified to include other necessary
inspection points. Follow the steps in this
section and check them off to ensure a
proper vehicle inspection procedure. The
pages in this section may be reproduced
locally and used on a regular basis.
If any component or system does not pass
this inspection, it must be corrected before
operating the vehicle. Take your time going
through the pre-trip inspection. Remember
that a careful pre-trip inspection saves time
by eliminating unscheduled stops to correct
a faulty item.
Vehicle Inspection
Preparation
Perform the following tasks prior to
conducting the pre-trip inspection.
Apply the parking brake.
Turn on the parking lamps and hazard
warning flashers.
Service and Maintenance
Unhook the hood latches and raise the
hood. Inspect both hood latches to
confirm proper operation.
Check under the vehicle for oil, fuel,
coolant leaks, or other signs of damage.
Exterior Lamps Check
Check the exterior lamps by performing the
following steps:
1. Turn the ignition on or to ACC/
ACCESSORY.
2. Switch the headlamps to the fully on
position and activate the fog lamps.
Ensure that the headlamps are in
low-beam mode. (Turn off high-beam.)
3. Turn on the cargo lamp.
4. Walk around the vehicle and inspect
illumination of lights. Parking lamps,
hazard warning flashers, low-beam
headlamps, and fog lamps should all be
illuminated. The cargo lamp should also
be illuminated.
5. Turn on the high-beam headlamps.
6. Verify that the high-beam headlamps are
now illuminated and the fog lamps have
switched off.
