START-UP AND USE

•Check for correspondence between the compressor plate data with the
actual specifications of the electrical system.Avariation of ± 10% with
respectoftheratedvalueisallowed.
•Inserttheplugofthepowercableinasuitablesocket(fig. 6)checkingthat
the button of the pressure switch located on the compressor is in the OFF

•Check the oil level by meansoftheoil dipstick (figures 7a- 7b), and if
necessarytopup.
•Atthispoint,thecompressorisreadyforuse.
•Operating on the switch of thepressureswitch (fig. 1), the compressor

•Please check that the air consumption and the maximum working
pressure of the pneumatic tool to be used are compatible with the
pressure set on the pressure regulator and with the amount of air
supplied by the compressor.
•Always pull out the plug and drain the receiver once you have completed
yourwork(figures 10-11).

•BEFORE CARRYING OUT ANY OPERATION, ALWAYS PULL OUT THE
PLUG AND DRAIN THE RECEIVER COMPLETELY (figures 10-11).
•Checkthatallscrews(inparticularthoseoftheheadoftheunit)aretightly

•After loosening any safety screws, clean the intake filter according to
the type of working environment and at least every 100 hours (figure
12).Ifnecessary,replacethefilterelement(cloggingofthefilterreduces

•Replace the oil after the first 100 hours of operation and every 300 hours
subsequently(figures 13a-13b-13c).Remembertochecktheoillevelat

•Spent oil (lubricated models) and condensate MUST BE DISPOSED
OF in accordance with environmental protection regulations and current
legislation.
The compressor must be disposed in conformity with the methods
provided for by local regulations.
