Circuit breaker/
fuse trips. Often
• Excessive wire length causes
voltage to drop too much.
• Restricted air passages.
• Back pressure in pump head.
- Link additional air hoses together to
acquire additional length;
DO NOT USE AN EXTENSION CORD
- Contact authorized service centre.
- Replace check valve and/or pressure
switch bleeder valve.
Overheating
• Poor ventilation.
• Dirty cooling surfaces.
• Leaking valve.
- Relocate compressor to an area with
cool, dry and well-circulated air.
- Clean all cooling surfaces of pump
and motor thoroughly.
- Replace worn parts and reassemble
with new seals.
Motor Stalls
• Low Voltage.
• Defective pressure switch bleeder
valve.
- Link additional air hoses together to
acquire additional length;
DO NOT USE AN EXTENSION CORD
- Replace pressure switch bleeder
valve.
Pressure relief
valve opens
• Tank pressure has exceeded
normal operating pressure.
• Pressure switch is stuck
- Replace pressure switch.
- Replace pressure switch.
Motor will not
run
• Tank pressure exceeds preset
pressure switch limit.
• Motor overload protection has been
tripped.
• Fuse blown or circuit breaker
tripped.
- Motor will start automatically when
tank pressure drops below kick-in
pressure of pressure tank.
- Allow the motor to cool off and the
overload switch will automatically reset.
This may take several minutes.
- Replace blown fuse or rest circuit
breaker. Do not use fuse or circuit
breaker with higher rating than specific
for your circuit branch. Check for
proper fuse; ‘Fusetron’ Type T is
acceptable.
- Check for low voltage and discontinue
use of extension cord.
- Disconnect other applications from
circuit.
- Operate compressor on a dedicated
circuit.
- Remove and clean or replace.
