Risk of damaging 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.
Strictly observe the lubricating oil manufacturer's product data sheets and safety
data sheets when handling lubricating oil. These are not included within the
scope of supply.
Check the planetary gearbox oil level:
Observe the information on the planetary gearbox dimensioned drawing in appendix
D "Technical data / Drawings" of the material number-specific operating
instructions!
• Bore 8: for filling the lubricating oil
• Bore 9: for checking or draining the lubricating oil
1
Allow the planetary gearbox cool down to approx. 50°C after standstill.
2
Turn the planetary gearbox as shown in the figure on the left: Bore 8 in 12 o'clock
position and bore 9 in 9 o'clock position.
3
Place a catch basin with sufficient capacity under the planetary gearbox.
4
Loosen the screw plugs of the bore 8 slowly, so that any existing pressure can be
released.
5
Then remove the screw plugs from bores 8 and 9. The oil level is correct if some
lubricating oil escapes from the bore 9.
6
If the oil level is too low, fill in lubricating oil. Proceed as described in chapter
8.1.3 "Filling the oil through the oil filler opening" or 8.1.4 "Filling the oil cooling
circuit of the planetary gearbox using an electric pump (pump not included in the
Rexroth scope of supply).
Check whether the seals on the screw plug threads of bore 8 and bore 9 are still
7
in perfect condition and can be reused. Replace the damaged seals.
8
Seal bore 8 and bore 9 with the corresponding screw plugs.
