6.7 On/Off switch (8)
To switch on the compressor, pull out the red knob
(8).
To switch off the compressor, press the red knob (8)
in again. (Fig. 2)
6.8 Adjusting the pressure: (Fig. 1)
You can adjust the pressure on the pressure
gauge (6) using the pressure regulator (7).
The set pressure can be taken from the quick-
lock coupling (5).
6.9 Setting the pressure switch
The pressure switch is set at the factory.
Switch-on pressure 6 bar
Switch-off pressure 8 bar
7. Cleaning and maintenance
Important!
Pull the power plug before doing any cleaning
and maintenance work on the appliance.
Important!
Wait until the compressor has completely cooled
down. Risk of burns!
Important!
Always depressurize the tank before carrying out
any cleaning and maintenance work.
7.1 Cleaning
Keep the safety devices free of dirt and dust as
far as possible. Wipe the equipment with a clean
cloth or blow it with compressed air at low
pressure.
We recommend that you clean the appliance
immediately after you use it.
Clean the appliance regularly with a damp cloth
and some soft soap. Do not use cleaning agents
or solvents; these may be aggressive to the
plastic parts in the appliance. Ensure that no
water can get into the interior of the appliance.
You must disconnect the hose and any spraying
tools from the compressor before cleaning. Do
not clean the compressor with water, solvents or
the like.
7.2 Condensation water
The condensation water must be drained off each
day by opening the drain valve (11) (on the floor of
the pressure vessel).
Important! The condensation water from the
pressure vessel will contain residual oil.
Dispose of the condensation water in an

environmentally compatible manner at the
appropriate collection point.
7.3 Safety valve (10)
The safety valve has been set for the highest
permitted pressure of the pressure vessel. It is
prohibited to adjust the safety valve or remove its
seal. Actuate the safety valve from time to time to
ensure that it works when required. Pull the ring with
sufficient force until you can hear the compressed air
being released. Then release the ring again.
7.4 Check the oil level at regular intervals
Place the compressor on a level and straight surface.
Unscrew the oil dipstick (Fig. 8/Item 14) by turning it
counter-clockwise and wipe the dipstick. Screw the
dipstick back into the filler opening as far as it will go,
screw out again and hold it horizontally to read off
the oil level. The oil level must be between the two
marks MAX and MIN on the oil dipstick (Fig. 8).
Changing the oil: Recommended hydraulic oil: SAE
15W/40 or an alternative of the same quality.
It should be refilled for the first time after 100 hours
of operation. Thereafter the oil should be drained and
refilled after every 500 hours in service.
7.5 Changing the oil
Switch off the engine and pull the mains plug out of
the socket. After releasing any air pressure you can
unscrew the oil drainage screw (15) from the
compressor pump. To prevent the oil from running
out in an uncontrolled manner, hold a small metal
chute under the opening and collect the oil in a
vessel. If the oil does not drain out completely, we
recommend tilting the compressor slightly.
Dispose of the old oil at a drop-off point for old
oil.
When the oil has drained out, re-fit the oil drainage
screw (15). Fill new oil through the oil filler opening
(14) until it comes up to the required level. Then re-
insert the oil dipstick (14).
7.6 Cleaning the intake filter (1)
The intake filter prevents dust and dirt being drawn
in. It is essential to clean this filter after at least every
300 hours in service. A clogged intake filter will
decrease the compressorʼs performance
dramatically. Remove the filter from the compressor
and undo the thumb screw on the air filter. You can
then remove the filter from the two halves of the
plastic housing, tap it to remove the dirt, blast it down
with low-pressure compressed air (approx. 3 bar)
and re-insert it. (Fig. 11)
