Draining the oil

The gear unit cover may only be opened by the SEW‑EURODRIVE Service team or specialists trained by SEW‑EURODRIVE.

  1. Perform the steps according to chapter Preliminary work regarding inspection and maintenance.
  2. WARNING! Risk of burns due to hot surfaces. Severe injury. Let the device cool down sufficiently before touching it.
    • However, the gear unit must still be warm, otherwise the low flowability of excessively cold oil will make it more difficult to drain the oil correctly.
  3. Remove the drive unit from the system. Otherwise an oil change is not possible.
  4. SEW-EURODRIVE recommends draining the oil at the position shown in the figure below.
  5. Place a sufficiently large container underneath the drain hole [2].
  6. WARNING! Risk of burns due to hot gear unit oil. Severe injury. Let the device cool down sufficiently before touching it.
  7. Remove the lowest screw plug [2] or the breather valve installed there (depends on the mounting position used according to the mounting position sheet).
  8. The oil draining procedure is facilitated if you remove the upper screw plug [3] or the breather valve that is screwed into the hole (air flows inwards).
  9. Drain the oil. All of the residual material [1] that is left in the drive must be extracted by using a suitable device.
