Check for blocking and cleaning of the radiator
The radiator has high efficiency and a limited level of blocking. In the case of anomalous over-temperatures it is recommended
to check the degree of blockage and in normal conditions at least once a year.
Proceed as following for cleaning:
• remove the rear and upper panels from the compressor cab;
• position a sheet of protective plastic under the radiant pack;
• spray (with washing gun + solvent) from inside towards the outside.
• check the perfect passage of air towards the radiator
EVERY 4000 HOURS
Oil replacement (fig.10)
Every 4000 hours of work (with hot compressor) replace the oil.
• Discharge the pressure in the oil-separator tank using tap A (fig.9).
• Insert the supplied flexible pipe into tap B.
• Unscrew the inlet well cap D, open tap B and allow the oil to flow out into
a collection recipient until it is completely discharged.
• When discharge has been completed close tap B and remove the pipe
• Pour in new oil through the inlet well D (quantity for complete filling: about 5
litres), and tighten the cap.
• Apply current to the machine.
• Start-up the machine and leave it running for 5 minutes then stop it.
• Discharge all air.
• Wait 3 minutes and check the oil level; top-up if necessary.
The oil must be replaced at the same time as replacement of the oil and oil-separator filters.
Recommended oil: RotEnergy Plus. (do not mix different types of oil).
WASTE OIL IS HIGHLY POLLUTANT: dispose of it in compliance with legal provisions
Replacement of the oil-separator filter (fig.13)
The oil-separator filter cannot be cleaned but must be replaced at every oil change.
In particular, pay attention to the pressure shown on the manometer (B). If, with the machine in
full working order (e.g. P max 10 bar), the pressure measured by the manometer is above 1 bar (=11
bar), it is ABSOLUTELY NECESSARY to replace the filter even if it is outside of the recommended
intervals.
• Discharge the compressed air completely by means of tap (A) (fig. 9).
• Loosen the filter manually by turning it in an anticlockwise direction.
• Replace it with a new filter, turning it in a clockwise direction after having lightly greased the
seal and the OR ring inside the oil-separator filter.
Replacement of the oil filter (fig.14)
At every oil change it is indispensable to replace the oil filter; this operation must be carried out
when the tank is not pressurised.
Always pass a thin layer of oil on the edge of the filter and on the seal before tightening.
MONTHLY
Discharge condensation
• Oil-separator tank (fig.10)
Cooling of the oil/air mixture is adjusted at a higher temperature with respect to the air dew point;
however, it is not possible to totally eliminate the presence of condensation in the oil.
Discharge the condensation once a month before starting up the compressor: open tap B and
close it again as soon as oil starts to escape instead of water.
Check the oil level and top-up if necessary.
• External air tank
Open the discharge valve positioned under the air tank by turning it in an anti-clockwise direction.
Position a collection recipient and leave it open until only air escapes.
CONDENSATION IS A POLLUTANT MIXTURE! And must not be introduced into the drain system.
Dispose of it in compliance with laws in force concerning environmental protection.
