Problem
Cause
Fix
System overheating
Oil level in the air compressor is low
Check for oil leaks and repair as needed. Use
ISO 68 viscosity hydraulic oil, filling to the mid-
dle of the sight glass.
Plugged water strainer at oil cooler
Remove strainer and clean screen.
Inadequate water supply
Verify that water is being circulated within the
pump (TANK TO PUMP valve completely open
with the TANK FILL valve 1/4 open).
Overheated water supply
Supply the pump with fresh cool water and open
a discharge valve or TANK FILL valve, allowing
the heated water to be dumped to atmosphere.
Compressor overspeeding in UNLOAD mode
Do not run compressor in excess of 8950 RPM.
Compressor speed can be calculated as follows:
drive line (engine) speed x 2.5 x gear ratio in the
pump transmission.
Temperature gauge inoperative
Wires unconnected
Check wire connections at the gauge, sending
unit and power supply.
Wires improperly connected
Check wiring for proper sequence (green to
large terminal; yellow to small terminal) - See F-
1031, Section 3027 (S100 Eclipse) or F-1031,
Section 3028 (CX Eclipse).
Excessive oil consumption
Reservoirs overfilled with oil
Check oil level while on a level surface. Reduce
level to middle of the sight glass.
Flowing in excess of 200 CFM
Reduce RPM and flow CAFS and recheck oil
level.
Oil/Air filter torn or damaged
Result of flowing air in excess of 200 CFM. Re-
place air filter, flow CAFS, shut down the pump
for 15 minutes and check oil level.
Oil siphon line and check valve
Check oil siphon line for obstruction and inspect
check valve for operation.
Excessive compressor bleed down time
(time may vary)
Inlet air trim valve closed too far
Reference “Control Air Circuit Calibration In-
structions” on Page 12.
Debris in inlet air trim valve
Clean valve and reference “Control Air Circuit Cali-
bration Instructions” on Page 12.
Engine stalls upon compressor engage-
ment
Electric Auto-Sync in FIXED or AUTO position
Place the Electric Auto-Sync in the UNLOAD
setting.
Engaging compressor when under load
Operating under this condition causes the com-
pressor oil to accumulate in the compressor cre-
ating a condition similar to a hydraulic pump. To
correct, allow air to bleed off, restart the com-
pressor and immediately begin flowing air
through a discharge.
Air compressor locked up
Due to a lack of compressor oil/lubrication. Re-
pair or replace the compressor.
