industrial gear oils in appendix B "Required and supplementary
documentations" in the material number-specific operating instructions for
these planetary gearbox.
10.4.2 Changing the lubricating oil
Damage to the planetary gearbox!
If you mix different oil types or the same oil types from different oil
manufacturers, this may change the oil properties!
For re-filling, always use the same oil type from one oil manufacturer.
Never mix synthetic lubricating oils with mineral oils or with other synthetic
lubricating oils.
Fill the planetary gearbox with the oil quantity indicated in the technical data.
Make sure to determine the exact oil quantity on the gearbox.
Carry out an oil change before the planetary gearbox has completely cooled
down. This ensures that solid particles have not yet settled.
Strictly observe the lubricating oil manufacturer's product data sheets and
safety data sheets when handling lubricating oil. These data sheets are not
included within Rexroth's scope of supply.
Change the lubricating oil at the intervals specified in the maintenance schedule. If
existing, observe the maintenance schedule in the material number-specific
operating instructions.
Performing the lubricating oil change:
Observe the information on the planetary gearbox dimensioned drawing in
appendix D "Technical data / Drawings" of the material number-specific operating
instructions!
