8.1.4 Filling lubricating oil via the oil filler opening on the cover side
Danger of burns!
The planetary gearbox heats up to a max. of 90 °C during operation in the oil
sump, so that you can burn yourself!
Allow the planetary gearbox to cool down to approx. 50 °C before touching.
To protect yourself from burns, wear appropriate protective clothing such as
heat-resistant safety gloves.
Always wear protective goggles.
Risk of injury!
Solid particles, such as metal particles or metal abrasion, which are in the
lubricating oil or on the screw plug can cause injury!
Wear appropriate protective clothing.
Due to the preserving oil already in the planetary gearbox, the oil quantity can
differ from the oil quantity indicated in the technical data sheet of the material
number-specific operating instructions when filling the planetary gearbox for
the first time. The exact oil volume has therefore to be determined on the
planetary gearbox.
Filling the planetary gearbox with lubricating oil on the cover side:
Refer to the figure on the left
• Bore 9: for filling the lubricating oil
• Bore 8: for checking or draining the lubricating oil
1
Turn the planetary gearbox as shown in the figure on the left: Bore 9 in 12
o'clock position and bore 8 in 9 o'clock position.
2
Place a catch basin with sufficient capacity under the planetary gearbox.
3
Loosen the screw plug of the bore 9 slowly, so that any existing pressure can
be released.
4
Remove afterwards the screw plugs from the bores 8 and 9.
5
Refer to the technical data sheet in appendix D "Technical data / Drawings" of
the material number-specific operating instructions for information on oil
viscosity and oil capacity.
6
Fill the planetary gearbox with clean lubricating oil via the bore 9. Fill sufficient
lubricating oil until some oil drains from bore 8.
7
Check whether the seals on the screw plug threads of bore 8 and bore 9 are
still in perfect condition and can be reused. Replace the damaged seals.
Seal bore 8 and bore 9 with the corresponding screw plugs.
8
9
Let the HYDROTRAC GFT 8000 planetary gearbox run for approx. 5-10 minutes.
10
Allow the planetary gearbox cool down to approx. 50 °C after switching off.
