PROBLEM
CAUSE
CORRECTION
Regulated
pressure
gauge reading
drops when
air accessory
is being used
This is normal
If pressure drops too low, adjust
regulator while accessory is used.
Compressor not
large enough
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.
Pressure relief
valve opens
Tank pressure
exceeded normal
operating pressure
Replace pressure switch
Pressure switch stuck
Replace pressure switch
Motor will
not run
Tank pressure exceeds
preset pressure switch
limit
Motor will start automatically when
tank pressure drops below cut- in
pressure of pressure tank.
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
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 valve stuck open
Remove and clean or replace.
Wrong wire gauge in cord
or excessive extension
cord length
Check for proper gauge and extension
cord length.
Loose electrical
connections
Contact authorized service center.
