COMPRESSOR LUBRICATION
CAUTION!
Before performing any operation involving draining or topping up compressor oil,
unplug the compressor and wait until the system has reached atmospheric pressure.
Use adequate protection when handling lubricants.
We recommend a lubricant compatible with the ISO VG 46 oil (mineral-based oil) used during
testing. The pour point must be at least -8+10°C and the flash point higher than +200°C.

For use of incompatible oils, follow the procedure described in chapter 6.4
Never mix different types of oil
We recommend using oil with a VG32 rating for cold climates and VG68 for tropical climates.
CAUTION: for machines without oil or warehouse storage for a long proceed as
described below:
Absence of oil:
1.
Place the oil in the reservoir through the oil filler plug provided (ch. 10.3). To see the
amount of oil provided the technical data (ch. 2).
2.
Feed
approximately 0.1
l
of lubricant in through the regulator intake opening while
keeping the suction valve shutter lowered and manually turning the screw rotors in the
right direction.
3.
Starting the compressor, initially alternating switching to short shutdowns, to facilitate
the filling of all the parts of the plant.
4.
Start the machine for about 10 minutes with average operating.
5.
Turn the machine off and wait for it depressurized (0 bar). Check the oil level by the
viewer (ch. 10.3) and, if necessary, proceed with the replacement of oil by means of the
filler cap on the tank (ch. 10.3).
Long storage
From Point 2 to point 5
