4 As shown on the adjustable working pressure gauge (4),
the pressure of the adjustable exit can be altered by
turning the pressure reducer (5).
Attention: In order to read the correct output at the output
gauge, air must flow through the output. The adjustable
valve must be set and the pressure gauge read with the
valve open, while the air flows from the output set through
the accessory.
In order to increase the air pressure, turn the valve clock-
wise. In order to reduce the air pressure, turn the valve
anti-clockwise.
Attention: The absence of air flow during setting produces
an incorrect display. For a correct display, air must flow.
5 Upon termination of your work, or when you leave the
compressor unattended, switch it off as follows:
• Press the ON/OFF switch (3).
• Wait until the compressed air has escaped via the drain
valve under the switch cover (2).
Attention: On pressing the button you should hear a short
air exit (about half a second).

• Switch the machine off and pull the mains plug.
• Pull the ring on the safety valve (8) in order to make
sure that the compressed air has escaped from the
tank, or open the drain plug of the tank in order to let
the pressure escape.
Maintenance
Fig. 14
1 After the first ten operating hours empty the oil in the
crank box and fill in clean oil. To do this, remove the oil
plug on the crank box (below left from the crank box).
Attention: SAE 30 or L-DAB 100 above 10 °C,
SAE 10 or L-DAB 68 below 10 °C.
2 After every 500 operating hours, drain the oil and fill
the crank box with clean oil.
3 After every operating day, drain the condensate from
the tank using the bleed screw (9).
4 Regularly check the air filter cartridge inside the air
filter unit (12) and replace the cartridge, if necessary.
5 Daily check the function of the safety valve. When
checking, the tank must be at maximum pressure.
For checking the valve, set the tank under pressure and
pull the ring on the safety valve to the outside.
There should be air escaping from the valve.
At releasing the ring from the safety valve, the escaping
air must stop.
Warnings
For this test goggles must be worn. Do not hold your face
close to the safety valve as there the air escapes at a high
pressure.
Should the safety valve not work properly as described
above, immediately switch off the compressor and have
the safety valve examined by your dealer.
