Pre- and Post-Trip Inspections and Maintenance

Safety Precautions

DANGER
When working on the vehicle, shut down the en-
gine, set the parking brake, and chock the tires.
Before working under the vehicle, always place
jack stands under the frame rails to ensure the
vehicle can not drop. Failure to follow these
steps could result in serious personal injury or
death.
Daily Pretrip Inspection and
Maintenance Procedures
Whenever equipment requires adjustment, replace-
ment, repair, addition of lubricants, or a change of
lubricants, see the Walk-In Van Chassis Workshop
Manual for repair procedures and specifications.
Specific references to the manual will be found
where appropriate.
1.
Drain manually drained air reservoirs (that are
not equipped with automatic drain valves).
Water and oil normally enter the air reservoir in
the form of vapor because of the heat generated
during compression. After the water and oil con-
dense, drain the resulting emulsion as follows:
1.1
Open the wet tank valve. The drain cock
or pull chain drain is located on the for-
ward end of the supply air reservoir, which
is connected directly to the air compres-
sor. Block the valve open.
WARNING
When draining the air reservoir, do not look into
the air jets or direct them toward anyone. Dirt or
sludge particles may be in the airstream and
could cause injury.
1.2 Exhaust the remaining air and moisture
from the system by opening the drain
cocks on the bottoms of the remaining air
reservoirs. Block the valves open.
1.3 Water and oil emulsion often form pockets
that will not drain while compressed air is
in the reservoirs. Because of these pock-
ets, leave the valves blocked open during
the first part of the pretrip inspection.

2. Check the coolant level in the surge tank.
See Fig. 11.1. If the coolant is low, add a 50/50
mixture of water and the type of antifreeze cur-
rently installed in your vehicle. Fill the surge tank
with coolant to the MAX line when the tank is
cool. See Table 11.1
the surge tank was empty, start the engine after
refilling, then check the level again when the en-
gine is at operating temperature.
