Check visually whether e.g. water, metal particles or mud are in the drained
lubricating oil.
8
In case of important contamination, find out the cause before refilling. Contact
the Rexroth Service located in your area, for the address refer to appendix
A "Address directory" in the material number-specific operating instructions.

If the lubricating oil is contaminated, flush the lubricating oil system carefully
before filling the planetary gearbox with new lubricating oil.
10
Dispose of this drained lubricating oil in accordance with local country
regulations.
11
Check whether the seals on the screw plug threads of the oil drain openings 8
are still in perfect condition and can be reused. Replace the damaged seals.
12
Screw the screw plugs of the oil drain openings 8 back into the bores.
13
Then fill the planetary gearbox with clean lubricating oil according to the
selection list – industrial gear oils. Proceed as described in chapter 8.1.4
"Filling the planetary gearbox with lubricating oil".
10.4.3 Greasing the output shaft bearing
If the output shaft bearing in the output shaft housing is permanently greased, the
planetary gearbox is not provided with a grease nipple. But if the bearing is
grease-lubricated, the planetary gearbox has at least one grease nipple 9.
Grease the output shaft bearing at the intervals specified in the maintenance
schedule. If necessary, use lithium multi-purpose grease L-XBCHA3 (GB 7324-
94) or FAG Arcanol MULTI3 or Klüberplex BE 31-222 to grease the output
bearing in the output shaft housing via grease nipples 9.
10.4.4 Maintenance of the static multiple-disk parking brake
The static multiple-disk brake integrated in the planetary gearbox is maintenance-
free if used as intended.
Risk caused by the failure of the static multiple-disk parking brake!
The use of the static multiple-disk parking brake for braking the gearbox may
cause its destruction.
Operate the static multiple-disk parking brake only after a complete stop of
the, e.g. superstructure.
Always replace the disks, the springs and the sealing elements after a
functional impairment or thermal overload and by any repair work on the
multiple-disk parking brake.
Danger of delayed stopping of the static multiple-disk parking brake!
Delayed application of the static multiple-disk parking brake can lead to
accidental turning of the e.g. superstructure.
Please ensure that the brake line of the static piston is pressureless within
0.5 s.
