TROUBLESHOOTING
Risk of Unsafe Operation. Unit cycles automatically when
power is on. When servicing, you may be exposed to
voltage sources, compressed air, or moving parts. Before servicing unit
unplug or disconnect electrical supply to the air compressor, bleed tank of
pressure, and allow the air compressor to cool.
PROBLEM CAUSE CORRECTION
Excessive
tank pressure
- safety valve
pops off Pressure switch does
not shut off motor when
compressor reaches "cut-
out" pressure. Move On/Auto/Off lever to the "Off"
position, if the unit does not shut off
contact a Trained Service Technician.
Pressure switch "cut-out"
too high. Contact a Trained Service Technician.
Air leaks at
fittings Tube fittings are not tight
enough. Tighten fittings where air can be
heard escaping. Check fittings with
soapy water solution. DO NOT OVER
TIGHTEN.
Air leaks at or
inside check
valve Check valve seat
damaged. A defective check valve results in
a constant air leak at the pressure
release valve when there is pressure
in the tank and the compressor is
shut off. Replace check valve. Refer
the "To Replace or Clean Check
Valve" in the Service and Adjustments
section.
Air leaks at
pressure switch
release valve Defective pressure switch
release valve. Contact a Trained Service Technician.
Air leaks in air
tank or at air
tank welds Defective air tank. Air tank must be replaced. Do not
repair the leak.
Risk of Bursting.
Do not drill into,
weld or otherwise modify air tank
or it will weaken. The tank can
rupture or explode.
Air leaks
between head
and valve plate Leaking seal. Contact a Trained Service Technician.
Pressure
reading on
the regulated
pressure gauge
(if equipped)
drops when an
accessory is
used It is normal for "some"
pressure drop to occur. If there is an excessive amount of
pressure drop when the accessory
is used, adjust the regulator as
instructed in the Operation section.
NOTE: Adjust the regulated pressure
under flow conditions (while
accessory is being used).
Air leak from
safety valve Possible defect in safety
valve. Operate safety valve manually by
pulling on ring. If valve still leaks, it
should be replaced.
