6 SERVICE, DISMANTLING, ASSEMBLY 6.7 OIL CHANGE
6.7 Oil Change
The separator should be level and at
standstill when oil is filled or the oil level is
checked.
6.7.1 Lubricating oil
Do not mix different oil brands.
Always use clean vessels when handling lubricating oil.
Great attention must be paid not to contaminate the lubricating oil. Of
particular importance is to avoid mixing of different types of oil. Even a
few drops of motor oil mixed into a synthetic oil may result in severe
foaming.
Any presence of black deposits in a mineral type oil is an indication that
the oil base has deteriorated seriously or that some of the oil additives
have precipitated. Always investigate why black deposits occurs.
If changing from one oil brand to another it is recommended to do this
in connection with an overhaul of the separator. Clean the gear housing
and the spindle parts thoroughly and remove all deposits before filling
the new oil.
