Maintenance
Disconnect power source
then release all pressure
from the system before
attempting to install, service, relocate
or perform any maintenance. Service
should be performed by an authorized
service representative.
The compressor should be checked
often for any visible problems and the
following maintenance procedures
should be performed each time the
compressor is used.
ASME SAFETY VALVE
attempt to adjust the safety valve!
Figure 6
Check the safety valve by performing
the following steps:
1. Plug the compressor in and run until
shut off pressure is reached (see
Operating Procedure).
2. Wearing safety glasses, pull the ring
on the safety valve to release
pressure from compressor tank. Use
your other hand to deflect fast-
moving air from being directed
toward your face.
3. The safety valve should
automatically close at approximately
40-50 psi. If the safety valve does not
allow air to be released when you
pull on the ring, or if it does not
close automatically, it MUST be
replaced.
DRAIN TANK
With compressor shut off and pressure
released: Drain moisture from tank by
opening drain valve underneath tank
(See Figure 7).
Figure 7
CLEANING
Turn power OFF and clean dust and dirt
from motor, tank, air lines and pump
cooling fins.
Do not
IMPORTANT: Unit should be located as
remove or
far from spraying area as hose will
allow to prevent over-spray from
clogging air filter.
AIR FILTER
Check air filter to be sure it is clean. To
service a filter, remove the filter
housing cover. Remove filter and clean
in hot, soapy water (Paper filters cannot
be washed). Rinse and let dry. Replace
air filters that cannot be cleaned. Place
filter back in the housing base. Replace
cover.
LUBRICATION
This is an oilless type compressor
requiring no lubrication.
THERMAL OVERLOAD PROTECTOR
pressor is equipped with an automatic
reset thermal overload protector which
will shut off motor if it becomes
overheated.
If thermal overload protector shuts
motor OFF frequently look for the
following causes:
1. Low voltage
2. Lack of proper ventilation
overload protector is actuated, the motor
must be allowed to cool down before
start-up is possible. The motor will
automatically restart without warning if
left plugged into electrical outlet and
unit is turned on.
