10. Cleaning, maintenance, and storage

m Important!
Pull out the power plug before doing any cleaning and
maintenance work on the equipment. Risk of injury
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 injury!
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 cleaningagents 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 com-
pressor) so that all the condensed water can run out
of the pressure 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 contact 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 suit-
able collection point.
10.3 Safety valve (Fig. 3)
The safety valve (17) has been set for the highest per-
mitted pressure of the pressure vessel. It is not permit-
ted to adjust the safety valve or remove the connec-
tion 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)
counterclockwise to open it and use your hands to
pull the valve rod outwards over the perforated ex-
haust nut (17.1) to open the safety valve outlet. Now,
the valve audibly releases air. Then, tighten the ex-
haust nut clockwise again.
10.4 Checking the oil level at regular intervals
(Fig. 11)
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 (12).
Oil change: we recommend SAE 15W 40 or equivalent.
The original oil filling must be changed after 10 hours
in operation; thereafter the oil must be drained and
replaced with new oil after every 50 hours in opera-
tion.
10.5 Changing the oil (Fig. 1, 10, 11)
Switch off the engine and pull the mains plug out of
the socket. Remove the oil sealing plug (15). After re-
leasing any air pressure you can unscrew the oil drain
plug (12) from the compressor pump (13).
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. When the oil has drained out, re-fit the oil drain
plug (12). 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 (19) until it comes
up to the maximum level.
