WARNING
All the routine and additional maintenance operations must be carried out with the machine at a standstill
(the compressor at a standstill) and with the power supply disconnected.
The residue pressure in the machine (pump circuit) must be eliminated.
Any operation carried out on the machine must only be undertaken having read and carefully applied the
regulations listed in Chapter 4 “Precautions for use and maintenance”.
All the operations described in the following paragraphs, for model MCH 26-32/ET Compact,
must be repeated twice (one for every component that is the same).
To keep the machine in good working condition, it must be cleaned very thoroughly.
Having been designed and built according to the most advanced technological criteria, this type of refill
station requires very limited preventive and routine maintenance operations.
However, it is essential to follow the indications given in this chapter very carefully and to follow the
intervals between operations as suggested.
