CHECKING AND CHANGING THE LUBRICATING OIL
7.6
After putting the compressor into service the lubricating oil must be changed after the first 50 working hours.
The lubricating oil must be changed every 250 hours working hours or annually.
IMPORTANT
The compressor must be placed on a solid surface with a tilt of no more than 5°.
DANGER
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.

Check that the level of lubricating oil (
a
) is within the
allowed limits (it must be above half the length of the
level indicator tube a) Note that an excessive
quantity of oil can cause infiltrations in the cylinders
and leave deposits on the valves while too low a
level prevents proper lubrication and could cause
engine seizure.
If the oil level is not within the minimum and
maximum limits top up or drain as described in
section “7.6.3 Changing the lubricating oil”.
