PROBLEM POSSIBLE CAUSE
Low pressure or Tank drain valve is open
not enough air
Fittings Leak
or compressor
does not stop
Restricted air intake
Prolonged excessive use of air
Compressor not large enough
Restricted check valve
Hole in air hose
Tank leaks
Blown seals
Valve leaks
Air leaks from Dirty or damaged regulator internal
regulator, or parts.
regulator does not
regulate pressure
Regulated This is normal
pressure gauge
reading drops
Compressor not large enough
when air accessory
is being used
Pressure relief Tank pressure exceeded normal
valve opens operating pressure
Pressure switch stuck
Motor will not run Tank pressure exceeds preset
pressure switch limit
Make sure the Thermal Overload
Switch has not tripped. The motor has
a built in thermal cut out that trips
when necessary to protect the motor
from damage when overheated.
Fuse blown or circuit breaker tripped
Check valve stuck open
Pressure bleeder valve on pressure
switch has not unloaded head
pressure
Wrong wire gauge in cord or excessive
extension cord length
Loose electrical connections
Possible defective capacitor
Paint spray on internal motor parts
Possible defective motor

TROUBLESHOOTING CHART

SOLUTION
Close drain valve
Check fittings with soapy water. Tighten or reseal leaking fittings.
DO NOT OVERTIGHTEN.
Clean or replace air filter element.
Decrease amount of air used.
Check air requirement of accessory. If it is higher than CFM and
pressure supplied by compressor, you need a larger compressor.
Most accessories are rated at 25% of actual CFM while running
continuously.
Remove and clean or replace.
Check and replace if necessary.
WARNING
Replace compressor assembly.
Replace compressor assembly.
Replace regulator or internal parts.
If pressure drops too low, adjust regulator while accessory is
used.
Check air requirement of accessory. If it is higher than CFM and
pressure supplied by compressor, you need a larger compressor.
Most accessories are rated at 25% of actual CFM while running
continuously.
Replace pressure switch
Replace pressure switch
Motor will start automatically when tank pressure drops below
kick-in pressure of pressure tank.
To reset the motor overload toggle turn the pressure switch ON/
OFF lever to the OFF position and unplug the unit from the
power outlet. Allow 10 minutes (minimum) for motor overload
cut-out to cool and reset. Unit can then be plugged in and
re-started.
Make sure power cord is plugged in and the switch is on. Inspect for the
proper size fuse in your circuit box. If the fuse was tripped, reset it and restart
the unit. Disconnect other applications from same circuit and operate
compressor on a dedicated circuit. If repeated tripping occurs, inspect the
check valve or contact customer service or technician.
Remove and clean or replace.
Bleed line by moving pressure switch lever to OFF Position
before restarting. If bleeder valve does not open, replace bleeder
valve.
• Check for proper gauge and extension cord length.
• See chart/label on unit.
Contact authorized service center.
Contact authorized service center.
Have checked at service center. Do not operate compressor in
the paint spray area
Have checked at service center.
Immediately replace tank. DO NOT attempt to
