Air Compressor

Troubleshooting

Always inspect the compressor before use, and make sure it is in good working condition. Make sure all air

vents are clear. Check the power cable to make sure it is intact and free from cracks, bare wires etc. Avoid

using solvents when cleaning plastic parts, most plastics are susceptible to damage from the various types of

commercial solvents.

Trouble Possible Cause Corrective Action

Compressor will not start 1. Blown fuse or circuit breaker

tripped

1. Replace or reset fuse/circuit breaker

2. Loose electrical connections 2. Check wiring connnections

Low pressure 1. Restricted air lter 1. Replace air lter

2. Defective check valve 2. Replace check valve

3. Air leak in safety valve 3. Check valve by pulling on ring. If

condition persists, replace valve

Safety valve releases Defective pressure switch Replace pressure switch

Pressure in tank falls 1. Air leaks at joints 1. Allow the compressor to build pres-

sure in the tank, to the max pressure if

possible. Spray or brush soapy water

on all air connections and look for bub-

bles. Tighten leaky connections. Do not

over-tighten.

2. If the problem continues, contact

customer support for further advice.

Unloader valve leaks when

pump is not running

Unloader valve seal defective Allow air in the air tank out until all

pressure is released. Remove the un-

loader valve plug and clean the valve

seal. If damaged, replace seal and

re-install.

Compressor stopped and will

not re-start

1. Thermal overload protector has

engaged due to motor overheat-

ing

1. Check that the main supplied

voltage corresponds to the compres-

sor specications. An inadequate

extension cord (too thin or too long)

can cause the motor to overheat due

to voltage drop. Excessive use (over

1 hour continuous) can cause motor

overheating. Allow the motor to cool

down.

2. Motor windings burn-out Contact customer support

Motor does not start and

makes a humming sound

Capacitor burn-out Contact customer support

Motor does not start or starts

slowly

Low voltage electrical supply to

motor

Check that the main supplied voltage

corresponds to the compressor speci-

cations.

An inadequate extension cord (too thin

or too long) can cause the motor to

overheat due to voltage drop.

Check power quality at outlet

Compressor runs noisily and

metallic sounds are heard

Compressor will not come to

max pressure

Head gasket or reed valve dam-

aged.

Stop the compressor and contact cus-

tomer support

Compressor doesn’t provide

as much air as when new

and/or cuts o after a much

shorter time period.

1. Tank has reduced capacity due

to water retention

2. Pressure switch is out of adjust-

ment

1. Open drain valve to release water

2. Contact customer support

Pump unit does not stop

when the tank reaches maxi-

mum working pressure.

Defective or pressure switch out

of adjustment

Stop the compressor immediately (risk

of explosion) and contact customer

support
