SYMPTOM
PROBABLE CAUSE
REMEDY
COMPRESSOR WILL NOT
START
No Fuel
Check fuel level and add fuel if necessary.
Plugged Fuel Filter
Replace the element.
Low Battery Voltage
Check electrolyte level and add distilled water
and recharge if necessary.
Loose battery cables; tighten cables.
Dirty battery cables; clean thoroughly.
Plugged Air Filter
Replace the element.
Engine Problems May Have
Developed
Refer to Engine Operator’s Manual.
Tripped Circuit Breaker on
Instrument Panel
Check and reset if necessary.
COMPRESSOR SHUTS
DOWNWITH AIR DEMAND
PRESENT
No Fuel
Check fuel gauge and add fuel if necessary.
Compressor Discharge
Temperature Switch is Open
Cooling air flow is insufficient; clean cooler
and check for proper ventilation.
Low fluid sump level; add fluid.
Dirty compressor fluid filter; change element.
Thermostatic element is not functioning prop-
erly; change the thermostatic element.
Defective discharge temperature switch;
check for a short or open circuit to the engine
fuel solenoid. Should this check out normal, it
could be possible that the temperature switch
itself is defective.
Tripped Circuit Breaker on
Instrument Panel
Check and reset if necessary.
COMPRESSOR WILL NOT
BUILD UP FULL DIS-
CHARGE PRESSURE
Air Demand is Too Great
Check service lines for leaks or open valves.
Dirty Air Filter
Check the filter gauges on instrument panel
and change element if required.
Pressure Regulator Out of
Adjustment
Adjust regulator according to control adjust-
ment instructions in the Maintenance section.
Defective Pressure Regulator
Check diaphragm and replace if necessary
(kit available).
Defective Air Inlet Cylinder
Replace cylinder.
IMPROPER UNLOADING
WITH AN EXCESSIVE
PRESSURE BUILD-UP
CAUSING PRESSURE
RELIEF VALVE TO OPEN
Fluid Charge Lost from Spring
Chamber on Inlet Valve
Add fluid to inlet valve spring chamber by
removing plugs (Fig. 5-3) in the top of the
spring chamber and filling with compressor
fluid. Some fluid may leak from the control
regulator at first but will stop leaking when
fluid level in the spring chamber equalizes.
Pressure Regulating Valve is Set
Too High
Readjust.
