-- 12.1) CHECKING COMPRESSOR OIL LEVEL --
Every morning before starting the machine check the oil level in the compressor tank. The compressor
oil level shall never fall below the minimum level notch and never exceed the maximum level either. It
shall fall between the two notches of min. and max. level.
Oil level checks must be undertaken a few hours after having stopped the machine, in order to allow the oil
to flow into the tank. In fact if the oil level is checked immediately after switching off the machine, a false
reading is given which means that the user will top up with more oil than is necessary.
-- 12.2) CHANGING COMPRESSOR OIL --
The oil in the compressor shall be changed every 2000 hours' operation or at least once a year.
To change the oil proceed as follows:
1. Change the oil when the machine is hot
2. switch off the compressor and disconnect the main switch.
3. Unscrew the oil plug on the tank side (part. A fig.3) after checking that the inside of the tank has
been fully depressurised
4. Open the drain valve on the tank bottom (part.B fig.4)
5. After draining the oil replace the oil filter cartridge by unscrewing and removing it from its seat.
Replace with a new one (12.3)
6. Fill with oil through the filler.
IMPORTANT
: Always use the same brand and type of oil as indicated in paragraph 2. In the event that it is
necessary to change the oil type (which must however be of an equivalent type as indicated in paragraph 2)
be sure to drain away all the lubricant from the entire circuit before adding a different type.
NEVER MIX DIFFERENT OIL TYPES.
