When changing oil, drain used oil as completely as
possible, as used oil greatly reduces the service
life of the new oil charge.
You must refrain from mixing different lubrica-
tion oils. When changing oil types, the oil must be
completely drained from the oil circuit.
You can find the maintenance intervals in the
maintenance plan.
Replacement times for the lubrication oil
Operating conditions (e.g. cooling medium temper-
atures), the type of operation and the quality of the
suction air (e.g. dust content, content of gaseous
foreign substances such as SO2, solvent vapours,
etc.) have a significant impact on oil change inter-
vals.
In such instances of usage, the permitted duration
of use of the oil must be checked with the help of
an oil analysis.
NOTE
Catch the used oil, do not allow it to seep into
the ground.
Dispose of according to the regulations! Do not
spill oil! Immediately capture any used oil! En-
sure leak-tightness!
