A128 - Check coolant
Orientation
For add-on equipment that cannot be cooled conventionally with cooling lubricants
or hydraulic fluid due to high temperature development, separate cooling is provided
in an independent cooling circuit. The coolant used here must be checked
continuously for its condition like other coolants.
Due to different requirements and/or specifications of the respective
manufacturers, be sure to review the respective manufacturer's
documentation!

For all work in connection with operating materials, the information in
the data sheets of the respective manufacturers and the information
in the document Notes on Operating Materials must be observed.
Requirement
Replenish only coolant of the same manufacturer having the same
specification. Mixing different coolants may lead to corrosion of the
cooling system and degradation of the coolant. The glycol content
must be min. 25%.
