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!
f For re-filling, always use the same oil type from one oil manufacturer.
f Never mix synthetic lubricating oils with mineral oils or with other synthetic
lubricating oils.
f Fill the planetary gearbox with the oil quantity indicated in the technical data.
f 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.
procedure
Check the oil level of the planetary gearbox t model.
f Observe the information on the planetary gearbox dimensioned drawing in
appendix D "Technical data / Drawings" of the material number-specific
operating instructions!
• Bore 5: for filling or checking the lubricating oil
• Bore 6 for 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 6 in 6 o'clock position.
3. Place a catch basin with sufficient capacity under the planetary gearbox.
4. Loosen the screw plugs of the bore 5 slowly, so that any existing pressure can
be released.
5. Then remove the screw plug from bore 5. The oil level is correct if some
lubricating oil escapes from the bore 5.
6. If the oil level is too low, fill in lubricating oil. Proceed as described in chapter
8.1.3 "Filling the planetary gearbox with lubricating oil".
7. Check whether the seal on the screw plug thread of the bore 5 is still in perfect
condition and can be reused. Replace the damaged seals.
8. Seal bore 5 with the corresponding screw plug.
