2. Warranty and complaints
The legal foundation of our guarantee management is the German Civil Code. But please consider the
following regulations:
 Work carried out on our compressors under guarantee is only done in our workshop as a matter of
principle because the machines are classified as easy to transport. In case of contact by others any
guarantee claim cannot be asserted.
 Equally guarantee does not apply, if the compressor has been modified or altered without
consultation and approval by our company.
 The guarantee is limited to the compressor only and includes material and manufacturing faults.
 Faults resulting from natural wear and tear, improper use, installation or insufficient maintenance are
disregarded. Wear and tear elements are:
 Solenoid discharge valve
 Non-return valve
 Pressure switch
 Air filter
 Fuse
Furthermore the tube cooler is excluded from guarantee in case of traceable use as carry handle,
what is not allowed and results destruction of itself.
 We reserve the right to determine how and by whom the repairs are to be made.
 Costs that may arise as an after-effect of the compressor’s breakdown will not be accepted by our
company.
3. Reference of utilization
3.1 conventional utilization
The compressor units with DC motor are designed for versatile applications in which a compressed air
supply is needed to permanent disposition.
The compressor is provided solely for production of compressed air. Any other use is considered improper.
The manufacturer is not responsible for any damages resulting from improper utilization – the risk carries
the operator by himself.
Correct use includes also the compliance with the manufacturer’s regulations of installation, operating and
maintenance.
3.2 unconventional utilization
The compressor unit must not be used in hazardous areas - it is not protected against explosions.
Without additional air treatment compressed air from oil lubricated compressors is not suitable for the filling
of breathing air equipment and use in dentistry or for operations where compressed air comes directly into
contact with food.
Compressed air must never be directed at people. The concentrated energy causes a life-threatening
situation.

under voltage protection and control light
1. Under voltage protection
The operator should provide an operating voltage between -10 % and +20 % of the rated voltage.
The following faults occur, when the operating voltage does not lie correctly:
a) The compressor cannot be switched on – Fault: operating voltage under -10% of rated voltage.
b) The compressor turns off automatically – Fault: operating voltage under -25% of rated voltage.
c) The compressor turns off automatically and can be switched on again only after the control
switched was turned off and a waiting time of about 10 seconds. – Fault: short interruption of
operating voltage or control line (loose connection).
A correct and safe operation is only guaranteed, when the connection follows the description of the
manufacturer or a confirmed (by the manufacturer) compliant circuit.
You have to be able to switch off the compressor at any time.
Any self-made changes in the original circuit during the legal warranty period cause an immediate
loss of any claims.
2. Control light
The control switch and light have to be installed within the operator’s viewing area.
An illumination of the control light indicates:
 Loose connection – Motor turns off automatically
 excess temperature – Motor turns off automatically and can be switched on after its cooling (ca. 45
min).
Please always investigate the reason of an occurring fault or glowing control light and arrange quick
remedy to avoid consequential damages.

6. Maintenance
We advise the owner/ operator of the following maintenance guideline that have to be kept necessarily.
General reference notes
Please be sure that the compressor unit is switched off completely. Pressure leading lines have to be
exhausted – drain the pressure in the container. Work on power-operated equipment must be carried out
only by trained personnel or by specialists.
Compressor block
Check the oil level every six months – the oil level is not allowed to fall below the red circle in the oil level
eye.
Attention:
If the oil level has dropped below the lower mark, oil must be refilled necessarily as it is
determined by the oil regulations. Under no circumstances should more oil be filled than
displayed in the max. oil level of the oil level eye.
 Switch off the compressor.
 Do an oil change every 500 operational hours or at least once per year.
 Unscrew the oil drainage screw and drain off all the oil in warm condition.
 Collect the oil in a receptacle and dispose of it correctly.
 The casing should be rinsed out with a small amount of new oil and then fill up with new oil.
 If due to unfavourable operating conditions water is discovered in the oil – this can be identified by a
milky coloration in the oil level eye – the oil must be changed immediately.
 Please consider using a sieve or the original can when refilling the oil.
Oil regulation: motor – Oil SAE 5 W30
Cylinder head and valves
 The cylinder head is to be unscrewed after 3.000 operating hours, the function of the valves is to be
checked and please clean the plate of the valve.
 Complete valve plates and/ or cylinder heads can be delivered from store.
 The compressor should be rebuilt after about 10.000 operating hours.
Clean and replace air filter
 The changeable insert in the air filter cap and the filter itself are made of foam or felt material.
 The filter should be replaced if a notable layer of dust is discovered on the filter or after 500 operating
hours at least.
Maintenance of the bearings and carbon brushes of the DC motor
 The motor bearings are permanently lubricated and do not require re-lubrication.
 Under normal operating conditions, with system and surrounding temperatures of about 25 °C, the
bearings should be replaced by new ones after about 10.000 hours of operation (rebuild).
 Increased wear of the bearings is to be expected if the surrounding temperature is much higher,
approx. 40 °C, whereby changing the bearings is recommended after about 5.000 operating hours.
 The bearings should be replaces after three years regardless of the number of operating hours.
 After 1.500 operating hours the dc motor should be cleaned inside. Please make a visual inspection
of the carbon brushes in that case.
 The carbon brushes are to be replaced as needed by the manufacturer or a specialist.
 If the commutator has shrunk considerably or if it is no longer round, it is necessary to rework this
by the manufacturer or a specialist.

10
Checking the safety valve
 If the maximum permissible operating pressure (10 bar) is exceeded in the pressure container, the
safety valve opens and ejects the excess air (at 11 bar) in order to protect the compressor and the
compressed air user attached to it.
 The safety valve must be bled occasionally in order to prevent the valve seat sticking.
 A defect safety valve has to be replaced completely.
 The compressor must be switched of thereby and the compressed air reservoir emptied.
Attention: Interventions in the controls are prohibited as such action cancels any liability.
Pressure container (accessory if requested)
 The condensed water that gathers in the pressure container must be drained off every day using
the condensed water drainage tap.
 Leaky pipe connections can lead to extensive loss of pressure.
 Occasional tightening of the pipe connections in necessary to prevent loss due to leakage.
Performance check
The effective performance of the compressor can be checked by measuring the compressed air reservoir
filling time:
 Switch off the compressor.
 Close the compressed air reservoir.
 Release container pressure using condensation drainage tag and then close it again.
 Switch on the compressor and simultaneously check the refill time until excess pressure and
compare it with the table.
Filling time in seconds (ca.) for 10-litre pressure container with the conditions of a constant
voltage. (1 V deviations are about 100 rpm)

Reference notes to anti-freeze pump
Your new compressor is equipped optionally with an anti-freeze pump that includes an anti-freeze
reservoir.
Please use the following notes to ensure the correct functionality of this equipment:
Anti-freeze: You can use a standard commercial anti-freeze.
Switching over the pump: (from winter to summer operation)
The pump can be switched from winter to summer operation of the compressor.
Blue – winter operation: slide to the right
Red – summer operation: slide to the left
Attention: Do not switch over when the compressor is working!
Setting the anti-freeze pumping capacity
The pump is set to the min. anti-freeze pumping capacity. Depending on the weather conditions the pump
can be set to a higher capacity by turning the adjusting screw (M6 hex socket screw) more toward the
outside.
Attention: First loosen the securing nut – then adjust the adjusting screw – then tighten the
securing nut again.
7. Safety regulations – environment protection
Explanation of the compressor’s danger sign:
Caution: Hot surface – Please touch only with safety gloves!
7.1 Safety regulations
The European standards provide the most important regulation that the owner/ operator has to care
about.
Furthermore we recommend considering the following:
 Be sure that no flames or sparks appear in the surroundings of the compressor.
 It is not allowed to switch on the compressor without the fan cover as protection from rotating parts.
The fan cover hast to be screwed tightly after any maintenance or reparation.
 Ensure that the compressor only intakes clean air without any detrimental mixture.
 Never use the tube cooler as carry handle because of possible damage (breakage) increasing the
loss of performance and possibility of injuries.
 During operation of the compressor, the tube cooler’s surface is very hot – only touch with safety
gloves.
7.2 Environment protection
Replacement parts, operating and auxiliary materials are to be disposed of according to the
corresponding environmental regulations.

9. Storing & Transport
 The storage should be dry to avoid corrosion.
 Temperatures under 0 °C could damage the compressor, if water would remain in the inside.
 During the transport the compressor must be standing.
 It must be screwed tightly on the four rubber mounts.
 Use a wood pallet to give more stability.
 Never let oil drain out of the compressor during the transport.
