Using The Air Compressor; Draining The Tank; Checking The Pressure Relief Valve - Ryobi RA-ACDDU1840 Operator's Manual

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.
wArNiNg
Always ensure the switch is in the OFF position and the
regulator 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.

See figure 8 - 10.
1. Ensure power switch is in the OFF position and air
compressor is unplugged.
2. If not already installed, attach hose to compressor as
previously instructed.
3. Attach 6.35 mm (1/4 in.) quick connect air fitting to
accessory or tool you intend to use.
4. Insert the other end of the quick connect air fitting to
the quick coupler (regulated pressure) on the open
end of hose.
5. Connect the power cord to the power supply.
6. Turn the power switch to the AUTO position.
7. Rotate pressure regulator knob to desired line
pressure. Turning the knob clockwise increases
air pressure at the outlet; turning counterclockwise
reduces air pressure at the outlet.
8. 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.
wArNiNg
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.
9. 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.
10. When finished, always drain the tank and unplug the
unit. Never leave the unit plugged in and/or running
unattended.
11. It is recommended to use a residual current device
with a rated residual current of 30 mA or less.

See figure 12-13.
To prevent tank corrosion and keep moisture out of the
air used, the air tank of the compressor should be drained
daily.
to drain:
1. Turn the air compressor off.
2. Pull the ring on the pressure relief valve to release until
pressure gauge reads less than 1.4 bar.
3. Release the ring.
4. Rotate drain valve lever clockwise to open and drain
the moisture.
NOte: Condensate is a polluting material and should
be disposed of in compliance with local regulations.
5. If drain valve is clogged, release all air pressure.
Remove and clean the valve, then reinstall.
Unplug the air compressor and release all air from
the tank before servicing. Failure to depressurize tank
before attempting to remove valve may cause serious
personal injury.
6. Rotate drain valve lever counterclockwise until tightly
closed.

See figure 13.
Do not attempt to tamper with the safety valve.
Anything loosened from this device could fly 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 tank pressure exceeds the preset maximum. The
valve should be checked before each day of use by pulling
the ring by hand.
1. Turn the air compressor on and allow the tank to
fill. The compressor will shut off when the pressure
reaches the preset maximum.
2. Turn the air compressor off.
3. Pull the ring on the safety valve to release air for three
to five seconds. Air should rapidly escape. Release the
ring and the air should stop.
4. The ring pin may need to be pushed back into position
to stop the flow of air at high pressure.
