RIDGID GP80150RT Operator's Manual page 13

OPERATION
 Allow the engine to run for 30 seconds, then move the
choke lever to the RUN position and place the pressure
unloader in the horizontal position.
NOTE: Once the air compressor is started, pressure
inside the air tank will build until the compressor reaches
150 psi. After reaching maximum tank pressure the
engine will idle allowing the pressure inside the air tank to
decrease until it reaches a preset level. When the pressure
falls below the preset level, the engine will accelerate and
provide additional air pressure.
WARNING:
Never exceed the air tool's pressure rating as
recommended by the manufacturer. When using
this air compressor as an inflation device, always
follow the maximum inflation guidelines stated by
the manufacturer of the item being inflated.
To stop the engine:
 Put the on/off switch in the OFF position.
WARNING:
The pump exhaust tube will become hot during
use. Avoid contact with the pump exhaust tube
when stopping the engine.
WARNING:
Always ensure the on/off switch is in the OFF (O)
position and the outlet pressure gauge reads zero
before changing air tools or disconnecting the hose
from the air outlet. Failure to do so could result in
possible serious personal injury.
 Turn the fuel valve to the CLOSED position.
USING THE AIR COMPRESSOR
This air compressor can be operated in 3 arrangements for
easy carry and ease of use.
NOTE: Before using the air compressor, always check the
safety valves for proper function as described in Checking
the Safety Valves later in this manual.
CAUTION:
Only use removable tank with air compressor Model
No. GP80150RT to avoid damage to the tool or
risk of personal injury.
WARNING:
The compressor tank will become hot during use.
Failure to avoid contact with the hot surface may
result in serious personal injury.
NOTICE:
Keep the air compressor on a flat, level surface
during operation. Operation of the unit at an angle
may result in damage to the air compressor and
could void your warranty.
COMPRESSOR TANK AND REMOVABLE TANK
TOGETHER — FOR MAXIMUM TANK CAPACITY
See Figures 16 - 18, pages 25 - 26.
Keep compressor tank and removable tank together for
maximum tank capacity.
 Make sure the air compressor is off.
 Attach hose(s) to one of the quick-connect couplers
(1/4 in.) on removable tank.
NOTE: If two tools are installed on the removable tank,
they must use the same psi.
 Attach a 1/4 in. NPT quick-connect air fitting to accessory
or tool(s) you intend to use.
 Insert the other end of the quick-connect air fitting to the
quick coupler on the open end of hose.
 Start the air compressor as described in Starting and
Stopping the Air Compressor.
 Check that ball valve lever on unregulated air hose is in
the ON position, allowing air flow from compressor tank
to removable tank.
 Pull out and rotate pressure regulator knob to desired
line pressure. Turning the knob clockwise increases air
pressure at the outlets; turning counterclockwise reduces
air pressure at the outlets.
 Following all safety precautions in this manual and the
manufacturer's instructions in the air tool manual, you
may now proceed to use your air-powered tool.
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 regulator
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.
