Risk of Unsafe
Operation. Unit cycles automatically when
PROBLEM
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
Hole in air hose
Tank leaks
Blown seals
Valve leaks
Leaking or worn piston
Air leaks from
Dirty or damaged regulator
regulator, or
internal parts .
regulator does not
regulate pressure
Regulated
This is normal
pressure
Compressor not large enough
gauge reading
drops when air
accessory is
being used
Pressure relief
Tank pressure exceeded
valve opens
normal operating pressure
Pressure switch stuck
Motor will not run Tank pressure exceeds preset pres-
sure 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 exces-
sive extension cord length
Loose electrical connections
Paint spray on internal motor parts
Possible defective motor
power is on. When servicing, you may be
exposed to voltage sources, compressed
air, or moving parts. Before servicing unit
CAUSE
Close drain valve
Check fittings with soapy water . Tighten or reseal
leaking fittings . DO NOT OVERTIGHTEN .
Clean or replace intake 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 .
Check and replace if necessary .
Replace seals .
Replace seals .
Replace piston .
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 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 .
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
Have checked at service center .
unplug or disconnect electrical supply to
the air compressor, bleed tank of pres-
sure, and allow the air compressor to cool.
CORRECTION
Immediately replace tank . DO NOT attempt to repair .
