18. PRODUCT MAINTENANCE
The operator should carry out device checks regularly in the intervals defined by
applicable regulations. Test results must be recorded.
The equipment has been designed and manufactured to keep maintenance to a minimum. The
following work must be performed to preserve the proper and reliable operation of the compressor.
Unauthorised interference hazard.
Repair work outside the framework of standard maintenance (see Chapter 18.1)
may only be performed by a qualified technician (an organisation authorized by
the manufacturer)
or the manufacturer’s customer service.
Standard maintenance work (see Chapter 18.1) may only be performed by the
operator’s trained personnel.
Only use manufacturer-approved replacement parts and accessories.
Danger of injury or equipment damage.
Prior to commencing compressor maintenance, it is necessary to:
- check if it is possible to disconnect the compressor from the appliance in
order to avoid any risk of injury to the person using the appliance or other
material damage;
- turn off the compressor;
- disconnect it from the mains (pulling the cord out of the mains socket);
- vent the compressed air from the air tank.
Prior to commencing dryer maintenance work, first:
- turn off the compressor and disconnect it from the mains
- check the pressure indicator on the dryer and if there is still pressure, it
must first be vented from the dryer chamber
Venting compressed air poses an injury hazard.
Wear eye protection, i.e. goggles, when venting compressed air from the
compressed air circuit (air tank) and from the dryer chamber.
Burn hazard.
When the compressor is running or shortly thereafter, certain portions of the air
pump, the compressor’s compressed air system, parts of the dryer and
connecting hoses between the compressor and dryer may be hot - do not touch
these components.
The removed grounding conductor during service must be connected back to the
original position after completing the service.

For any maintenance or repair work, the compressor may be removed from the cabinet by pulling
it from the cabinet (on rolling casters as much as the cord between the compressor and the
cabinet allows). (see chap. 18) The required maintenance or repair work may then be performed.

If the cord between the compressor and the cabinet becomes disconnected (by pulling the mains
plug, see chap. 12.2), the compressor shall not be functional. In order to bring the compressor
into function again, please follow, see chap. 12.2 or 18.8 or 18.9.
