Maintenance - RIDGID GP80150RT Operator's Manual

OPERATION
CAUTION:
Air powered tools may require more air consumption
than this air compressor is capable of providing.
Check the tool manual to avoid damage to the tool
or risk of personal injury.
 Control the amount of air flow with the pressure regula-
tor knob. Turning the knob fully counterclockwise will
completely stop the flow of air.
NOTE: Always use the minimum amount of pressure
necessary for your application. Using a higher pressure
than needed will drain air from the tank more rapidly and
cause the unit to cycle on more frequently.
 When finished, always stop the engine and drain the
tanks. Never leave the unit running unattended.
DRAINING THE TANKS
See Figure 21, page 27.
To help prevent tank corrosion and keep moisture out of the
air used, the air tanks of the compressor should be drained
daily.
NOTE: The air compressor has two tanks and two drain
valves. Be sure to perform this operation for each tank.
To drain:
 Make sure the air compressor is off.
 Pull the ring on the safety valve to release air until tank
pressure gauge reads less than 20 psi.
 Release the ring.
 Rotate drain valve counterclockwise (ON) to open.
 Tilt tank to drain moisture from tank into a suitable
container.
NOTE: Condensate is a polluting material and should be
disposed of in compliance with local regulations.
 If drain valve is clogged, release all air pressure, remove
and clean valve, then reinstall.
WARNING:
Stop the air compressor, disconnect the spark
plug wire, and release all air from the tanks before
servicing. Failure to depressurize tanks before
attempting to remove valve can cause serious
personal injury.
 Rotate drain valve clockwise (OFF) until tightly closed.
 Repeat above procedure for second tank.
WARNING:
RISK OF BURSTING. All compressed air
tanks have a limited lifespan. The lifespan can
be affected by a number of factors, including
operating conditions of the air compressor, proper
maintenance of the tank, and unauthorized repairs
and modifications. Since deterioration of the tank
can occur internally with no outward signs, the
air tank(s) on this compressor MUST be removed
from service by the end of the year shown on the
data label.
Tank life may be extended beyond this date by
having a certified tank inspection performed
before this date, and every 5 years following this
date, for as long as the tank is in use. Use of the
air compressor after this date without passing the
certified inspection increases the risk of an air tank
rupture, which could result in serious personal
injury.
CHECKING THE SAFETY VALVES
See Figure 21, page 27.
DANGER:
Do not attempt to tamper with the safety valves.
Anything loosened from this device could fly up
and hit you. Failure to heed this warning could
result in death or serious personal injury.
Safety valves will automatically release air if the air tank
pressure exceeds the preset maximum. The valves should be
checked before each day of use by pulling the ring by hand.
NOTE: The air compressor has two safety valves. Be sure
to check both.
 Start the air compressor and allow the tanks to fill. The
compressor will shut off when the pressure reaches the
preset maximum.
 Turn the air compressor off.
 Pull the rings on both safety valves to release air for three
to five seconds.
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 safety
valve has been replaced. Use of the air compressor
in this condition could result in serious personal
injury.
