• Clean the equipment 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 equipment. Ensure that no water can
get into the interior of the equipment.
• 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.
12. Maintenance
12.1 Maintenance work on the pressure vessel/
condensed water (Fig. 1)
m Important!
To ensure a long service life of the pressure ves-
sel (7), drain off the condensed water by opening
the drain valve (9) each time after using.
Release the vessel pressure first (see 13.1). Open
the drain screw by turning counter-clockwise (looking
at the screw from the bottom of the compressor) so
that all the condensed water can run out of the pres-
sure vessel. Then close the drain screw again (turn
it clockwise). Check the pressure vessel for signs
of rust and damage each time before using. Do not
use the compressor with a damaged or rusty pres-
sure vessel. If you discover any damage, then please
contact the customer service workshop.
12.2 Safety valve (Fig. 2/Pos. 16)
The safety valve (16) has been set for the highest per-
mitted pressure of the pressure vessel. It is prohibited
to adjust the safety valve or remove its seal. Actu-
ate 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 re-
leased. There lease the ring again.
12.3 Checking the oil level at regular intervals
(Fig. 10)
Place the compressor on a level and straight surface.
The oil level must be between the MAX and MIN
marks on the oil level window (18).
Oil change: we recommend SAE 15W 40 or equiva-
lent. The original oil filling must be changed after 100
hours in operation; thereafter the oil must be drained
and replaced with new oil after every 500 hours in
operation.
12.4 Changing the oil (Fig. 10)
Switch off the engine and pull the mains plug out of
the socket. After releasing any air pressure you can
unscrew the oil drain plug (20) from the compressor
pump. To prevent the oil from running out in an un-
controlled 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.

When the oil has drained out, re fit the oil drain plug
(20).
Dispose of the old oil at a drop-off point for old oil.
To fill in the correct quantity of oil, make sure that
the compressor stands on an even surface. Fill new
oil through the oil filler opening (14.1) until it comes
up to the maximum level. This is marked with a red
dot on the oil level window (18) (Fig. 10 pos. 18.1).
Do not exceed the maximum filling quantity. Overfill-
ing the equipment may result in damage. Reinsert the
oil sealing plug (14) into the oil filler opening (14.1).
12.5 Cleaning the intake filter (Fig. 12, 13)
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 de-
crease the compressor's performance dramatically.
Open the thumb screw (G) to the remove the intake
filter. Then pull off the filter cover (J). Now you can
remove the air filter (L) and the filter housing (K).
Carefully tap out the air filter, filter cover and filter
housing. Then blow out these parts with compressed
air (approx. 3 bar) and reinstall in reverse order.
Service information
Please note that the following parts of this product
are subject to normal or natural wear and that the fol-
lowing parts are therefore also required for use as
consumables.
Wear parts*: belt, piston, piston rings, cylinder

13. Storage
m Important!
Pull out the mains plug and ventilate the equip-
ment and all connected pneumatic tools. Switch
off the compressor and make sure that it is se-
cured in such a way that it cannot be started up
again by any unauthorized person.
m Important!
Store the compressor only in a dry location
which is not accessible to unauthorized persons.
Always store upright, never tilted!
13.1 Releasing excess pressure
Release the excess pressure by switching off the
compressor and using the compressed air which
is still left in the pressure vessel, e.g. with a com-
pressed air tool running in idle mode or with a blow-
out pistol.
