AEG AC3050B, Original Instructions 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 (O) 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.

USING THE AIR COMPRESSOR

See figure 9 - 10.

1. 

Ensure power switch is in the OFF (O) 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 switch ON ( l ).

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.  Rotate pressure regulator locking ring fully counterclockwise to 

lock the air pressure.

9.  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.

10.  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.

11.  When finished, always drain the tank and unplug the unit. Never 

leave the unit plugged in and/or running unattended.

12.  It is recommended to use a residual current device with a rated 

residual current of 30 mA or less.

CHECKING THE PRESSURE RELIEF VALVE

See figure 11.

 WARNING

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.

 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.

DRAINING THE TANK

See figure 12.

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.  Turn the drain valve counterclockwise 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.

 DANGER

Unplug the air compressor and release all air from the tank before 
servicing. Failure to depressurise tank before attempting to 
remove valve may cause serious personal injury.

6.  Turn the drain valve clockwise until tightly closed.

RESET BUTTON

See figure 13.

When current into the air compressor motor exceeds the specified 
limit, the air compressor will automatically shut off.

To reset the air compressor:

1. 

Unplug the air compressor.

2.  Turn the air compressor off.

3.  Wait three minutes for the motor to cool.

4.  Press the reset button.

5.  Plug the air compressor into an approved outlet.

6.  Turn the air compressor on.

NOTE:

 If you start the air compressor and the reset device operates 

again, stop the compressor and disconnect from the power supply 
and have your compressor examined by an authorised service centre.
