Trouble Remedy
Air compressor stops after short period
of operation.
Check compressor oil level (see Section 5-5). Automatic shutdown stops compressor if compressor tem-
perature is too high.
Circuit breaker CB5 is open. CB5 automatically resets when the compressor cools. If CB5 continues to
open, contact Factory Authorized Service Agent.
Check fan operation. Fan should run whenever compressor is on. Have Factory Authorized Service
Agent check fan circuit.
Clean debris from oil cooler. Automatic shutdown stops compressor if compressor temperature is too
high. Recirculation or open covers may cause overheating. Be sure all covers, panels, and doors are in
place. Operate in area with proper airflow.
Low air pressure. Check for leaks in air lines and hoses, including control line.
Reduce air demand.
Close air outlet valve.
Adjust compressor air pressure (see Section 7-2).
Check air compressor air cleaner (see Section 10-3).
Check compressor belt and tension. Be sure correct belt is used and is properly installed. Replace belt
if damaged or stretched.
Have Factory Authorized Service Agent check compressor blow down valve, and for leaks in control
lines. Also check air compressor for rated output.
High air pressure. Adjust compressor air pressure (see Section 7-2).
Verify control line is connected at regulator valve and inlet valve. Check for frozen control lines.
Check air/oil separator, and replace if plugged (see Section 10-3).
Have Factory Authorized Service Agent check for leaks in control lines, and also check air gauge, com-
pressor air inlet valve, safety valve, air pressure switch, and internal heating system.
Insufficient air delivery. Check air compressor air cleaner (see Section 10-3).
Check air/oil separator, and replace if plugged (see Section 10-3).
Check engine speed, and adjust if necessary.
Check compressor belt and tension. Be sure correct belt is used and is properly installed. Replace belt
if damaged or stretched.
Have Factory Authorized Service Agent check compressor air inlet valve, safety valve, air pressure
switch, and internal heating system.
Oil in air from compressor. Check compressor oil level (see Section 5-5). If oil level is too high, system becomes saturated with oil.
Change compressor air/oil separator if close to replacement hours (see Section 10-3).
Check connections of control lines.
Have Factory Authorized Service Agent check for plugged oil scavenge line.
Air compressor overheats. Check compressor oil level (see Section 5-4). Automatic shutdown stops compressor if compressor tem-
perature is too high.
Verify adequate air flow to compressor. Check for blocked air intake. Recirculation or open covers may
cause overheating. Be sure all covers, panels, and doors are in place. Operate in area with proper airflow.
Automatic shutdown stops compressor if compressor temperature is too high.
Adjust compressor air pressure (see Section 7-2).
Replace compressor oil filter (see Section 10-4).
Have Factory Authorized Service Agent check cooling fan. Automatic shutdown stops compressor if
compressor temperature is too high.
Have Factory Authorized Service Agent check thermal valve element, and replace if necessary.
Have Factory Authorized Service Agent clean compressor cooler core.
Oil in compressor air cleaner. Have Factory Authorized Service Agent verify compressor inlet valve is operating properly.
Water in compressor oil. Operate air compressor to remove water.
Moisture in compressor air. Install optional air cooler with separator (Part No. 300 420), or desiccant dryer (Part No. 195 117).
System retains pressure after shutdown. Have Factory Authorized Service Agent check compressor blow down valve, and leak back from airline.
