10. Cleaning, maintenance and storage

m Important!
Pull out the power plug before doing any cleaning
and maintenance work on the equipment. Risk of in-
jury from electric shock!
m Important!
Wait until the equipment has cooled down complete-
ly! Risk of burns!
m Important!
Always depressurize the equipment before carrying
out any cleaning and maintenance work! Risk of in-
jury!
10.1 Cleaning
• Keep the equipment free of dirt and dust as far as
possible. Wipe the equipment with a clean cloth or
blow it down with compressed air at low pressure.
• We recommend that you clean the equipment im-
mediately after you use it.

• 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.
10.2 Maintenance work on the pressure vessel
(Fig. 1)
Important! To ensure a long service life of the
pressure vessel (8), drain off the condensed wa-
ter by opening the drain valve (10) each time af-
ter using.
Release the vessel pressure first (see 10.7.1). 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 pressure
vessel. If you discover any damage, then please con-
tact the customer service workshop.
m Important!
The condensed water from the pressure vessel will
contain residual oil. Dispose of the condensed water
in an environmentally compatible manner at a suita-
ble collection point.
10.3 Safety valve (Fig. 3)
The safety valve (17) has been set for the highest
permitted pressure of the pressure vessel. It is not
permitted to adjust the safety valve or remove the
connection lock (17.2) between the exhaust nut (17.1)
and its cap (17.3).
Actuate the safety valve every 30 operating hours but
at least 3 times a year, to ensure that it works when
required.
Turn the perforated exhaust nut (17.1) counterclock-
wise to open it and use your hands to pull the valve
rod outwards over the perforated exhaust nut (17.1) to
open the safety valve outlet. Now, the valve audibly
releases air. Then, tighten the exhaust nut clockwise
again.
10.4 Checking the oil level at regular intervals
(Fig. 11)
Place the compressor on a level and straight sur-
face. The oil level must be between the MAX and
MIN marks on the oil level window (12).
Oil change: we recommend SAE 15W 40 or equiva-
lent.
