UNIT OPERATION
Pre-trip Inspection (Before Starting Unit)
The following pre-trip inspection should be completed
before starting the unit and loading the truck. While pre-trip
inspection is not a substitute for regularly scheduled mainte-
nance inspections, it is an important part of the preventive
maintenance program designed to head off operating prob-
lems and breakdowns before they happen.
1.
FUEL. The diesel fuel supply must be adequate to
guarantee engine operation to the next check point.
2.
ENGINE OIL. The engine oil level should be at the
FULL mark. Never overfill.
3.
COOLANT. The engine coolant must have antifreeze
protection to -30 F (-34 C). Check and add coolant in
the expansion tank.
CAUTION: Do not remove expansion tank cap
while coolant is hot.
4.
BATTERY. The terminals must be clean and tight.
5.
BELTS. The belts must be in good condition and
adjusted to the proper tensions.
6.
ELECTRICAL. The electrical connections should be
securely fastened. The wires and terminals should be
free of corrosion, cracks or moisture.
7.
STRUCTURAL. Visually inspect the unit for leaks,
loose or broken parts and other damage. The condenser
and evaporator coils should be clean and free of debris.
Check the defrost drain hoses and fittings to be sure
they are open. The damper in the evaporator outlet
must move freely with no sticking or binding. Make
sure all the doors are latched securely.
