Buffer fluid

BA-Classic FL_en-US, 03.05.2018
The purity of the lubricant influences the service life of the oil and
gear unit, plus general operating safety.
Therefore, always ensure that the gear unit contains clean oil!
Instructions for changing the oil/lubricant contained in the oper-
ating manual of the Börger device must be strictly adhered to.
The amount of remaining used oil in the gear unit must be kept as
low as possible, even when the same oil type is used for the oil
change.
NOTE!
Gear oils of different types or from different manufacturers
must not be mixed together.
When necessary, a confirmation of oil compatibility with the used
oil must be obtained from the manufacturer of the new oil.
If the composition of the new oil type deviates greatly from the
used oil (e.g. additives), then the used oil must be completely
removed from the gear unit. In this case, the gear unit must be
flushed carefully with the new oil. Gear oils must not become
contaminated with other substances, including any residue from
cleaning agents (e.g. petrol). Therefore, flushing with petrol or
other cleaning agents is not permitted.
Any fluids with good lubricant qualities that do not react with any of
the materials they come into contact with are suitable as buffer
fluids.
Pay attention to compatibility with the residual buffer fluid when
filling or refilling.
In order to rule out damage to the gear unit as comprehensively as
possible, even in the exceptional case that buffer fluid enters the
gear unit (e.g. due to improper maintenance of the gear unit), the
buffer fluid should also be compatible with the gear oil. See
Ä Chapter 9.8.4 "Oil types" on page 192.
