- Proper preservation of the compressor requires thorough cleaning.
- This type of refill station, designed and built according to the most advanced technological criteria, 

requires only minimum preventive and routine maintenance.

- Before carrying out any maintenance tasks, run checks and/or controls on the compressor, switch off the 

compressor, remove the plug from the mains socket.

- The residual pressure present in the compressor (pumping circuit) must be released.
- During disassembly and re-assembly of the compressor, always use suitable wrenches/tools so as not to 

damage the relevant components.

- Loosen stiff parts with a copper or plastic mallet.
- When refitting parts make sure they are clean and lubricated sufficiently.
- Compressor maintenance tasks must only be carried out by authorised personnel and recorded in the 

“Maintenance register” section of this manual.

Involves repair and/or replacement of the mechanical parts of one or more compressor components: this work
normally needs doing only after some years of use. If substantial modifications are made, the manufacturer
cannot be held liable for any dangers that might arise.
This work must be carried out by the assistance centre.

All maintenance tasks must be carried out with the compressor off and the power lead 
unplugged from the mains socket.
