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
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, 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.
Remove and clean or replace.
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.
