8.11 Overload switch (Fig. 14)
The motor is fitted with an overload switch (26). If the com-
pressor overloads, the overload switch switches off the
equipment automatically to protect the compressor from
overheating. If the overload switch triggers, switch off the
compressor using the ON/ OFF switch (17) and wait until
the compressor cools down. Then press the overload switch
(26) and restart the compressor.
9. Electrical connection
The electrical motor installed is connected and ready
for operation. The connection complies with the appli-
cable VDE and DIN provisions.
The customer's mains connection as well as the exten-
sion cable used must also comply with these regula-
tions.
Important information
In the event of an overloading the motor will switch itself off.
After a cool-down period (time varies) the motor can be
switched back on again.
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
fastened 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 regu-
larly. Make sure that the connection cable does not hang on
the power network during the inspection.
Electrical connection cables must comply with the applica-
ble VDE and DIN provisions. Only use connection cables
with the marking „H05VV-F".
The printing of the type designation on the connection cable
is mandatory.
AC motor
• The mains voltage must be 220 - 240 V~ 50 Hz.
• Extension cables up to 25 m long must have a cross-sec-
tion of 1.5 mm
.

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 completely! 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 pos-
sible. Wipe the equipment with a clean cloth or blow it
down with compressed air at low pressure.
• We recommend that you clean the equipment immedi-
ately 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 equip-
ment. 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 com-
pressor with water, solvents or the like.
10.2 Maintenance work on the pressure vessel (Fig. 1)
m Important! 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 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 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 work-
shop.
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 (19) 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.
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 (18).
