Check and perform the services listed in daily before-operation services.
0.1
2
LUBRICATION
Inspect the unit for missing or damaged lubrication fittings and for signs of
0.5
insufficient lubrication. Correct deficiencies noticed.

FRAME ASSEMBLY GROUP
Inspect the frame assembly group for satisfactory condition. Check the wheels
0.5
for proper lubrication by rotating wheels and listening for quiet wheel bearing action.
Lack of lubrication or defective bearings will be detected by bearing noise. check the
wheels for proper tire inflation pressure using a tire pressure gauge. The tire pressure
should be approximately 20 psi (1.406 kgs/sq cm) when towing the air compressor at 5
mph (8.046 km/hr) on a macadam surface. Reference LO 5-4310-335-12 for wheel
bearing lubrication.
6
GASOLINE ENGINE GROUP

tightness of fit and secureness of clamping. Tighten and secure any loose fittings or
component. Inspect the pressure gages located on the instrument panel of the frame
assembly for pressure indication on zero position. Inspect and replace if necessary, the
moisture separator and sphere safety cap tape. Inspect the air reservoir pad, replace if
necessary. Check the service hose, chuck and female quick disconnect, replace
defective components.
8
COMPRESSOR/COOLER ASSEMBLY
