3. Performance specifications
3.1. Intended use
The compressor is an oil lubricated air compressor. The ambient air is sucked in via the intake
filter and cleaned. The air drawn in is then compressed in the cylinder. The compressed air
flows into the pressure tank and is now available to supply the connected compressed air
tools. This compressor is designed exclusively for compressing air.
NO flammable gases and/or paint and dust mist may be sucked in with this compressor. It
may not be used in potentially explosive atmospheres as this may lead to serious or fatal
accidents with high material damage.
The suction of flammable gases etc. can lead to deflagration and explosions. This can
result in serious to fatal injuries and extensive damage to property!
The compressor has a finger guard and is thus protected against the penetration of medium-
sized foreign bodies (from Ø 12.5 mm).
It is not protected against the penetration of liquids. Therefore the equipment must not be
used in damp or wet rooms or outdoors in the rain. Always ensure that it is stored and used
in a dry place.
Penetration of foreign bodies and liquids can damage the unit and considerably
reduce its performance and service life.
Any other use or use that exceeds this is considered as not in accordance with the intended
purpose.

3.3. Main components
Figure 1
The compressor is supplied with a pre-set pressure valve control. The operating and switch-
on pressure can be controlled via the setting options.
The maximum permissible pressures and flow rates must not be exceeded under any
circumstances.
If the permissible operating pressures and flow rates are exceeded, this can lead to
serious accidents and damage to property.
3.4. Getting the machine ready for operation
To disconnect the compressor from the mains completely, the unit must be switched off using
the switch (Fig. 2) and then disconnected from the mains by pulling the mains plug.
The compressor can only be prepared for operation by people with sufficient technical
expertise. All other operators must have the installation commissioned by a specialist.
Never loosen parts of the compressor while there is still compressed air in the container.
Sudden pressure release can lead to operating conditions that are difficult to control
and can cause serious injuries.
Never work on the compressor circuit without disconnecting the mains plug. Only operate the
compressor with the stipulated mains voltage. Never use cables that are longer than 5 m or
have a diameter of less than 4 mm². Never pull out the mains plug to switch off the
compressor, but rather press the “off” switch (Fig. 2). If the supply line is not long enough, a
longer pressure hose is recommended.
Touching live components can lead to current flowing through the body and thus to
fatal injuries.

Varying device voltage or fluctuations in voltage can lead to operating faults and
reduce the service life of the device.
If the respective drain valve (Fig. 2 1 or 2) does not work once the motor has been switched
off, you should rectify the problem immediately. If this is not done, the motor could be
damaged when the compressor is switched on again. To do this, follow the instructions for
correcting malfunctions in Chapter 8 of this manual.
Failure to observe the safety instructions can result in damage to property and
personal injury.
Before the compressor is restarted with the reset button, check why it is no longer running
(pressure must always remain below 0.8 MPa). See Chapter 8 Troubleshooting if errors occur.
3.5. Oil level
The oil level of the compressor oil must be kept in the red indicator circle of the sight glass
(Fig.4 no. 13).
Recommended compressor oil:
SAE30 or L - DAB 100 for temperatures >10 °C
SAE10 or L - DAB 68 for temperatures <10 °C
If the wrong oil is used or the oil level is incorrect, this can damage the compressor
and negatively affect the performance of the unit.
Fill up oil and drain off:
Use a screwdriver to remove the cover of the oil filler opening at the top of the crankshaft
housing. If necessary, top up with compressor oil or oil of the quality specified here.
To get the correct oil level the compressor should be placed on a flat load-bearing
surface with wheels and support feet.
Always use the same type of oil. Never mix different types of oil.
Observe the oil level indicated in the sight glass at the front of the housing. The centre of the
red marking shows the correct oil level. Before operating the compressor, close the oil filler
opening again. To drain the compressor oil, unscrew the oil drain plug underneath the sight
glass.
Make sure the unit cannot be switched on if the oil has been drained. Switching the
compressor on without oil can damage it.

4. Compressor operation
4.1. Preparation for use
The following checks must be carried out before using the machine:
Make sure that all bolts and nuts are fully tightened. If necessary tighten the nuts!
Make sure that the area where the compressor is used is clean, dry and well ventilated.
Make sure that the electrical voltage is constant and does not deviate from the prescribed
voltage by more than 4%.
Open release valve 1 or 2 before the first start. Pull the switch to “on”. Let the compressor
run for 10 minutes without load to check that all moving parts are lubricated
Test the tension on the V-belt. Position 2 fingers centrally on the belt and press down.
The V-belt is correctly tensioned when it can be pressed down approx. 10 - 15 mm.
Make sure that the oil level is within the red indicator circle.
Recommended compressor oil:
SAE30 or L - DAB 100 for temperatures >10 °C
SAE10 or L - DAB 68 for temperatures <10 °C
Open the release valve before the first start. Turn the switch to “on”. Let the compressor run
for 10 minutes without load to check that all moving parts are lubricated.
Figure 2
The left pressure gauge is used to read the working pressure and the right pressure gauge
shows the current boiler pressure of the container. Adjustable compressed air can be tapped
via the release valve 1 with the quick coupling. Release valve 2 is also equipped with quick
coupling and provides unrestricted compressed air.

4.2. Using the compressor
The compressor is controlled by a pressure valve when it is in operation. When the set or
maximum permissible pressure is reached, the motor automatically switches off. It restarts
automatically once a previously set, lower pressure has been reached.
Start the compressor by lifting the on/off switch (see Fig. 2).
It is recommended that the unit be run once until the maximum boiler pressure has been
reached and the unit switches off automatically. Only then should the desired air tools be
connected.
As soon as the motor is switched off, the air in the vent pipe above the relief valve should be
vented. This prevents damage to the motor on restart.
The set pressure can be adjusted using the adjusting screw (Fig. 3). However, this should not
be done without a good reason and the permissible operating pressure of the compressor
should never be exceeded.
If the permissible operating pressure is exceeded and safety switches and valves are
manipulated, this could result in uncontrollable operating conditions. Failure of the
components can lead to serious accidents and extensive damage to property.
The outlet pressure can be adjusted via the adjustment valve. Pull the knob upwards and turn
it counter-clockwise or clockwise to reduce or increase the pressure (Fig. 2).
To stop the compressor, press the switch shown in Figure 2.

If add-on parts and supply lines lack the necessary stability, they can fail as a result
of overloading, causing accidents where people are injured.
To prevent supply lines from swinging around uncontrollably due to unintentional
loosening, these lines/hoses should be secured with a rope or suchlike.
During operation, the compressor surfaces can become particularly hot. Avoid
touching these components. To prevent fires, these surfaces must stay uncovered
and must be cleaned immediately of dust and deposits. Before any maintenance work
is carried out and before it is stored, the compressor should be completely cooled
down.
Carefully release the hose coupling. When you release the hose coupling, hold the coupling
piece of the hose firmly with your hand to avoid injuries due to the hose springing back.
4.3. Operating a pressure tank
Anyone operating a pressure tank must maintain it in a proper condition, operate it properly,
monitor it, carry out necessary maintenance and repair work without delay and take the safety
measures that are needed under the circumstances.
In individual cases, the competent supervisory authority may order the necessary monitoring
measures.
A pressure tank may not be operated if it has defects that endanger employees or third
parties.
The pressure tank must be checked regularly for damage, e.g. rust. If you discover any
damage, contact your specialist dealer immediately.
4.4. Operation at cold temperatures
At low temperatures, the oil in the crankcase becomes thick and viscous, which can lead to
start-up problems.
If necessary, do the following when operating your compressor in the colder seasons:
1. Let the pressure in the boiler run down to zero.
2. Open the water drain screw at the bottom of the boiler (Fig. 2 no. 7).
3. Switch on the compressor by pulling up the on/off switch (Fig. 2).
4. Let the compressor run for 2-3 minutes with the water drain screw open. During this time
the unit heats up.
5. After the warm-up time has elapsed, close the water drain screw again.
6. Now the boiler can fill or build up pressure.
If the compressor still does not start, place it in a temperature-controlled room for
about ½-1 hour so that it can warm up.
