5.2.13 Changing the oil
The position of the oil drain screw (optionally the drain tap), vents and devices for checking the oil
level can be obtained from the specific dimension sheet for the order.
WARNING
Danger of burns
Danger of burns due to hot oil.
• Allow the gear unit to cool down before carrying out maintenance or repair work
• Wear protective gloves
Procedure:
1. Select a collection vessel according to the stated quantity of oil 7.3.3 "Lubricant quantities"and
place it under the oil drain screw or the oil drain tap (optional).
2. Unscrew the vent from the gear unit.
3. Unscrew the oil drain screw or the sealing plug from the oil drain tap and open it.
4. Completely drain the oil from the gear unit.
5. Clean the interior of the gear unit by flushing with oil so that oil sludge particles, due to wear and
old residues, are removed. The same type of oil as is used for operation must be used for this.
6. Clean the thread of the oil drain screw or the sealing cap of the oil drain tap and coat with securing
adhesive (e.g. Loctite 242 or Loxeal 54-03) before screwing in again. In both cases, tighten the
screws with the correct torque (7.4 "Torque values").
7. Fill the gear unit with the specified quantity of fresh oil according to the type plate through the vent
hole. If the gear unit is equipped with a dipstick, the oil may be filled through this hole.
8. After approx. 15 minutes (for oil level tanks 30 minutes) check the oil level as described in Section
5.2.6 "Oil level"and correct as necessary.
9. Other attached components, e.g. filters and piping should also be drained if necessary.
10. For gear units with oil circulation lubrication and oil supply systems, the oil bearing system must be
drained according to the manufacturer's specifications (maintenance instructions).
