Check and correct the following:
a) Unit shut down while compressor under load
b) check inlet control valve seal
– repair as required
Symptom:
Engine Smoking Lack of Power
Check and correct the following
a) Check coolant level
b) Air in fuel filter
c) Operating in hot environment (air intake can be routed to outside fresh air)
d) High air pressure check
e) Low fuel pressure/delivery (min 4psi running)
Symptom:
Engine runs okay at low speed/air pressure but smoke at high speed/air pressure
Check and correct the following
a) Bleed fuel filter
b) Check fuel supply
c) Check coolant level
Symptom:
Compressor builds air while engine cranking and/or continues to build pressure after reaching set
pressure.
Check and correct the following
a) Blocked passage on inlet control tube
– (18) on page 22
b) Faulty inlet solenoid valve
– (19) on page 22
c) Damaged/leaking inlet valve disc.
– (14) on page 22. Usually noted by oil inside of
compressor air filter
*Note: Inlet valve is held closed by case pressure when not calling for air pressure
Symptom:
Unit cycles rapidly during tool/equipment use (indicates compressor producing more air than required)
Check and correct the following
a) Decrease engine rpm (contact dealer for proper procedure)
