Filling Lubricating Oil Via The Oil Filler Opening - Bosch rexroth HyDrotrAC GFt Operating Instructions Manual

8.1.4 Filling lubricating oil via the oil filler opening
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!
f Allow the planetary gearbox to cool down to approx. 50 °C before touching it.
f To protect yourself from burns, wear appropriate protective clothing such as
heat-resistant safety gloves.
f 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!
f 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.
procedure Filling the planetary gearbox t model with lubricating oil.
f Refer to the figure on the left
• Bore 5: for filling or checking the lubricating oil
• Bore 6 for draining the lubricating oil
1. Turn the planetary gearbox as shown in the figure on the left: Bore 6 in 6 o'clock
position.
2. Place a catch basin with sufficient capacity under the planetary gearbox.
3. Loosen the screw plugs of the bore 5 slowly, so that any existing pressure can
be released.
4. Then remove the screw plug from bore 5.
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 5. Fill sufficient
lubricating oil until some oil drains from bore 5.
7. Check whether the seal on the screw plug thread of the bore 5 is still in perfect
condition and can be reused. Replace a damaged seal.
8. Seal bore 5 with the corresponding screw plug.
9. Let the HYDROTRAC GFT planetary gearbox run for approx. 5-10 minutes.
10. Allow the planetary gearbox to cool down to approx. 50°C after switching off.
