must be disposed of

The service life of the machine depends on maintenance quality.

PRIOR TO ANY OPERATION SET THE PRESSURE SWITCH TO THE OFF POSITION, PULL

OUTTHE PLUGAND COMPLETELY DRAIN THE RESERVOIR.

Check that all screws (in particular those of the head of the unit) are tightly drawn up (fig. 9). The

check must be carried out prior to the first compressor starting.

Clean the suction filter according to the type of environment and in any case at least every 100

hours. If necessary, replace the filter (a clogged filter impairs efficiency while an inefficient filter

causes harsher wear on the compressor (figures 10a - 10b).

Change the oil after the first 100 hours of operation and subsequently every 300 hours. Check the

oil level periodically.

Never mix different grade oils. If the oil changes color (whitish = presence of water; dark =

overheated), it is good practice to replace the oil immediately.

After topping up, tighten the plug (fig. 11) making sure that there are no leaks during use. Once a

week, check the oil level to assure lubrication in time (fig. 6a).

Periodically (or after completing work if for more than an hour), drain the condensate that forms

inside the reservoir due to the humidity in the air (fig. 12) in order to protect the reservoir from rust

and so as not to restrict its capacity.

Periodically, check the tension of the belts which must have a flexion of around 1 cm (fig. 13).

* Spent oil and condensate in compliance with protection of the environment

and current legislation.
