7.6.1 - OIL TABLE
Sump capacity

Recommended oils
COLTRI OIL CE750
CHEMLUBE 751
After putting the compressor into service the oil filter and the lubricating oil itself must be changed after the
first 50 (fifty) working hours.
Replacement of the filter and the lubricating oil must be done every 250 hours working hours or annually.
The compressor must be placed on a solid surface with a tilt of no more than 5°.
IMPORTANT:
7.6.2 - CHECKING THE OIL LEVEL
The oil level must be checked every 5 working hours
of the compressor.
The oil level must be between the minimum and the
maximum shown on the oil level indicator (
a
).
If the oil level is above the maximum level:
- position a recipient under the drain tap (
b
)
so that the oil flows into the exhausted oil
recipient;
- open the drain tap and let the oil flow out
until the oil level returns within the max. and
min. limits;
- close the drain tap (
b
).
If the oil level is below the minimum level:
- open the top-up plug (
c
);
- top up with oil until the level
returns within the max. and min. limits;
- close the top-up plug (
c
).
Do not carry out these tasks if the compressor has only just shut down; wait for the
compressor to cool.
Any oil spilt during the oil/filter change could cause personnel to slip; wear protective
garments and anti-slip footwear and remove any traces of oil immediately.
Both oil and filter are classified as special wastes and must therefore be disposed of in
compliance with the anti-pollution laws in force.
All maintenance work must be carried out with the compressor OFF and the power supply lead
unplugged from the mains socket.
