8.1 Fitting the wheels (fig. 6, 7)
• Insert the wheel bolt (d) through the wheel (3) and
slide on a washer (e) with the bolt (d). Now feed
the wheel bolt (d) through the hole provided on the
compressor. Slide the washer (c) and the spring
washer (f) onto the bolt and secure the wheel with
the hexagonal nut (g).
• Carry out the same procedure with the second
wheel (3).
8.2 Fitting the supporting foot (fig. 5)
• Slide the hexagonal screw (a) through the foot
(4). Fit a washer (c) between the compressor and
the foot (4). Now feed the combination through
the hole provided and secure the screw (a) with a
washer (c) and nut (b).
• Carry out the same procedure with the second
foot (4).
8.3 Mains connection
• The compressor is equipped with a mains cable
with shock-proof plug. This can be connected to
any 230V~ / 50 Hz shock-proof socket which is
protected by a 16 A fuse.
• Before you use the machine, make sure that the
mains voltage is the same as the operating voltage
(see the rating plate).
• Long supply cables, extensions, cable reels etc.
cause a drop in voltage and can impede motor
start-up.
• At low temperatures below +5 °C, sluggishness
may make starting difficult or impossible.
8.4 ON/OFF switch (fig. 2)
• To switch on the compressor, press the button (8)
on position I.
• To switch off the compressor, press the button (8)
on position 0.
8.5 Setting the pressure (fig. 2)
• You can adjust the pressure on the pressure gauge
(6) using the pressure regulator (7).
• The set pressure can be taken from the quick lock
coupling (5).
8.6 Setting the pressure switch
• The pressure switch is set at the factory.
Cut-in pressure approx. 6 bar.
Cut-out pressure approx. 8 bar.
8.7 Overload protection switch (fig. 8 pos. 12)
• The compressor has an automatic protection
against thermal overload. The overload protector
is activated at high engine temperature.
• The device is turned off. Re-commissioning of the
device can be done only after cooling down and
manual reset.
• Follows after activation:

– Let the unit cool down,
– Press the overload protection switch (12)
8.8 Safety valve (fig. 1)
The safety valve (15) 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 (15.2) between the exhaust nut (15.1) and its
cap (15.3).
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 (15.1)
counterclockwise to open it and use your hands to
pull the valve rod outwards over the perforated ex-
haust nut (15.1) to open the safety valve outlet. Now,
the valve audibly releases air. Then, tighten the ex-
haust nut clockwise again.

9. 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 ex-
tension 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.
• The product meets the requirements of EN 61000-
3-11 and is subject to special connection conditions.
This means that use of the product at any freely se-
lectable connection point is not allowed.
• Given unfavourable conditions in the power supply
the product can cause the voltage to fluctuate tem-
porarily.
• The product is intended solely for use at connec-
tion points that
a) do not exceed a maximum permitted supply
impedance "Z" (Zmax = 0.382 Ω), or
b) have a continuous current-carrying capacity of
the mains of at least 100 A per phase.
• As the user, you are required to ensure, in consulta-
tion with your electric power company if necessary,
that the connection point at which you wish to oper-
ate the product meets one of the two requirements,
a) or b), named above.
Damaged electrical connection cable
The insulation on electrical connection cables is of-
ten damaged.
This may have the following causes:
• Passage points, where connection cables are
passed through windows or doors.
