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.
