9.5 Compressor oil (Fig. L)
• Remove the oil plug (y) from the oil filler hole.
• Fill the compressor oil supplied into the compressor
pump housing and fit the oil plug (18) into the oil
filler hole.
• Check the oil level using the sight glass (16). The
oil level must be within the red circle.

10. Before commissioning

• Before connecting the machine, make certain that
the data on the type plate matches with the mains
power data.
• Fill the compressor pump housing with oil as
described in point 8.5.
• Check the device for transport damage. Report
any damage immediately to the transport company
which was used to deliver the compressor.
• Install the compressor near the point of consumption.
• Avoid long air lines and supply lines (extension
cables).
• Make sure that the intake air is dry and free of dust.
• Do not deploy the compressor in damp or wet areas.
• Operate the compressor only in suitable areas (well
ventilated, ambient temperature +5°C to 40°C).
There must be no dust, acids, vapours, explosive
gases or inflammable gases in the room.
• The compressor is designed to be used in dry rooms.
It is prohibited to use the compressor in areas where
work is conducted with sprayed water.
• The oil level in the compressor pump must be
checked before commissioning.
• The compressor may only be used outdoor briefly
when the ambient conditions are dry.
• The compressor must always be kept dry and must
not be left outdoors after work is complete.

11. Start up

m ATTENTION!
Always make sure the device is fully assembled
before commissioning!
11.1 ON/OFF switch (Fig. G)
Pull the ON/OFF switch (5) upwards to switch on the
compressor. Press the ON/OFF switch down to switch off.
11.2 Pressure adjustment: (Fig. A; B)
The pressure at the manometer (9) is adjusted with the
pressure regulator (8).
The pressure set can be drawn from the quick coupling (10).
The boiler pressure is read off at the manometer (11).
The boiler pressure is taken at the quick-coupling (19).
11.3 Pressure switch position (Fig. A)
The pressure switch (7) is set in the factory. Switch-on
pressure approx. 8 bar, switch-off pressure approx. 10
bar
11.4 Overload switch
The motor is equipped with an overload switch. If
the compressor is overloaded, the overload switch
switches off automatically to protect the compressor
against overheating. If the overload switch has
triggered, switch the compressor off at the on/off switch
(5) and wait until the compressor has cooled down.
Now press the overload switch (34) and switch the
compressor on again.
11.5 Relieving the overpressure after work is
complete
Release overpressure in the compressor by switching
off the compressor and using up the compressed air
still in the pressure vessel, e.g. with a compressed air
tool running at idle or with an air blow gun.

12. Electrical connection

The electrical motor installed is connected and
ready for operation. The connection complies
with the applicable VDE and DIN provisions.
The customer's mains connection as well as the
extension cable used must also comply with these
regulations.
When working with spray attachments and during
temporary use outdoors, the device must be
connected to a residual current circuit breaker with a
trigger current of 30 mA or less.
Important information
In the event of 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
damaged.
