PROBLEM
Regulated
pressure
gauge reading
drops when air
accessory is
being used.
Pressure relief
valve opens.
Motor will
not run.
CAUSE
This is normal.
Compressor not
large enough.
Tank pressure
exceeded normal
operating pressure.
Pressure switch stuck.
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. Remove and clean or replace.
Wrong wire gauge in cord
or excessive extension
cord length.
Loose electrical
connections.
Paint spray on internal
motor parts.
Possible defective motor. Have checked at service center.
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
cut-in pressure of pressure tank.
To reset the motor overload toggle
turn the Power Switch 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.
• Replace blown fuse or reset
circuit breaker. Do not use fuse or
circuit breaker with higher rating
than specified for your branch circuit.
• Check for proper fuse; "Fusetron"
type T is acceptable.
• Check for low voltage and
proper extension cord size.
• Disconnect other applications
from circuit. Operate compressor
on a dedicated circuit.
Check for proper gauge and extension
cord length.
Contact authorized service center.
Have checked at service center. Do
not operate compressor in the paint
spray area.
