CHECKING THE PRESSURE RELIEF VALVE
See Figure 7-8.
DANGER
Donotattempttotamperwiththepressurereliefvalve.
Anythingloosenedfromthisdevicecouldyupandhit
you.Failuretoheedthiswarningcouldresultindeathor
serious personal injury.
The pressure relief valve will automatically release air if
the air receiver pressure exceeds the preset maximum.
The valve should be checked before each day of use by
pulling the ring by hand.
gTurntheaircompressoronandallowthetanktoll.The
compressor will shut off when the pressure reaches the
preset maximum.
g Turn the air compressor off.
g Pull the ring on the pressure relief valve to release air for
 threetoveseconds.
gReleasethering.Airmustimmediatelystopescaping
when the ring is released. Any continued loss of air
after releasing the ring indicates a problem with the
 pressure relief valve. Discontinue use and seek service
before continued use of the air compressor.
WARNING
If air leaks after the ring has been released, or if the valve
is stuck and cannot be actuated by the ring, do not use the
air compressor until the pressure relief valve has been
replaced. Use of the air compressor in this condition
could result in serious personal injury.
THERMAL OVERLOAD PROTECTION
This compressor is equipped with a thermal overload protector
which will shut off motor if it becomes overheated.
IfoverloadprotectorshutsmotorOFFfrequently,lookforthe
following causes.
Low voltage
Lack of proper ventilation/room temperature too high
Wrong gauge wire or length of extension cord
To reset the air compressor:
g Turn the air compressor off.
g Unplug air compressor and wait until compressor cools
down.
g Plug the air compressor into an approved outlet.
g Turn the air compressor on.
