10.2 Damaged electrical connection cable
The insulation on electrical connection cables is often dam-
aged.
This may have the following causes:
• Passage points, where connection cables are passed through
windows or doors.
• Kinks where the connection cable has been improperly fas-
tened or routed.
• Places where the connection cables have been cut due to
being driven over.
• Insulation damage due to being ripped out of the wall outlet.
• Cracks due to the insulation ageing.
Such damaged electrical connection cables must not be used
and are life-threatening due to the insulation damage.
Check the electrical connection cables for damage regularly.
Make sure that the connection cable does not hang on the
power network during the inspection.
Electrical connection cables must comply with the applicable
VDE and DIN provisions. Only use connection cables of the
same designation.
The printing of the type designation on the connection cable
is mandatory.
10.3 AC motor
• The mains voltage must be 220 - 240 V∼ 50 Hz.
• Extension cables up to 25 m long must have a cross-section
of 1.5 mm

Connections and repairs of electrical equipment may only be
carried out by an electrician.

11. Cleaning, maintenance and storage
m Attention!
Pull out the power plug before doing any cleaning and mainte-
nance work on the equipment. Risk of injury from electric shock!
m Attention!
Wait until the equipment has cooled down completely! Risk of
burns!
m Attention!
Always depressurize the equipment before carrying out any
cleaning and maintenance work! Risk of injury!
11.1 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 immediately
after you use it.
• Clean the equipment regularly with a damp cloth and some
soft soap. Do not use aggressive cleaning agents or solvents;
they could attack the plastic parts of the device. Make sure
that no water can penetrate the device interior.
• You must disconnect the hose and any spraying tools from
the compressor before cleaning. Do not clean the compres-
sor with water, solvents or the like.
11.2 Maintenance work on the pressure vessel (fig. 1)
Attention!
To ensure a long service life of the pressure vessel (8), drain
off the condensed water by opening the drain valve (10) each
time after using.
Release the vessel pressure first (see 11.8.1). 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 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 Attention!
The condensed water from the pressure vessel will contain re-
sidual oil. Dispose of the condensed water in an environmen-
tally compatible manner at a suitable collection point.
11.3 Safety valve (fig. 3)
The safety valve (19) 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 (19.2) between the
exhaust nut (19.1) and its cap (19.3). 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
(19.1) counterclockwise to open it and use your hands to pull
the valve rod outwards over the perforated exhaust nut (19.1)
to open the safety valve outlet. Now, the valve audibly releases
air. Then, tighten the exhaust nut clockwise again.
11.4 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: recommended oil: SAE 15W 40 or equivalent. The
original oil filling must be changed after 100 hours in opera-
tion; thereafter the oil must be drained and replaced with new
oil after every 500 hours in operation.
11.5 Changing the oil (fig. 1, 9, 10)
Switch off the engine and pull the mains plug out of the socket.
Remove the oil sealing plug (16). After releasing any air pres-
sure you can unscrew the oil drain plug (12) from the compres-
sor pump (13).
To prevent the oil from running out in an uncontrolled man-
ner, hold a small metal chute under the opening and col-
lect the oil in a vessel. If the oil does not drain out com-
pletely, we recommend tilting the compressor slightly.
When the oil has drained out, re-fit the oil drain plug (12).
