Safety valve
The safety valve is set to the maximum allowable pressure of the pressure vessel and protects the
compressor. As soon as the air in the vessel reaches or exceeds the maximum permissible operating
pressure, the safety valve opens and lets the compressed air escape, thus reducing the pressure in the
compressor.
ATTENTION: It is not allowed to adjust the safety valve or to remove the lock on the connection
between the drain nut and its cap.

7. CLEANING, MAINTENANCE AND STORAGE
ATTENTION Clean and maintain your compressor carefully and regularly. This is the only way to
ensure smooth operation and a long service life. Irrespective of the number of jobs or performances,
service and clean the unit after each use.
As far as possible, inspections, adjustments and maintenance work should be carried out by the same
person or his substitute and documented in a maintenance book.
Be sure to observe the following instructions when carrying out maintenance and cleaning work:
• Disconnect the compressor before performing any work on it.
• Disconnect the compressor from the mains by unplugging it. This disconnects the compressor from the
mains.
• Release pressure from the compressor to avoid material damage. You can, for example, connect a
compressed air blow gun to the compressor and thus empty the pressure vessel.
• Before each use, check the machine for damage, especially the cable and plug.
• Check the safety valve.
• The machine must not be used if any of the safety components are damaged.
• Use only original spare parts and accessories.
• Do not clean the machine and its parts with solvents, flammable or toxic materials.
• Clean the device only when it is switched off and cool.
• Clean the housing only with a soft, slightly damp cloth.
• Before servicing, clean the device of any hazardous substances that may have accumulated on it (due
to work processes). Avoid any skin contact with these substances. If the skin comes into contact with
hazardous dusts, it may cause severe dermatitis. If dust is generated or raised during maintenance work,
it can be inhaled.

ATTENTION:
ONLY IN CASE OF AIR LEAKAGE THROUGH THE
SAME AND DRAINAGE MAINTENANCE
Turn the drain nut counterclockwise (Fig. 13) to
open the safety valve outlet. The safety valve now
audibly releases air. Then retighten the drain nut
clockwise.
Repeat this process every 30 operating hours or at
least three times a year.
