Gear units with oil expansion tank /ET

INFORMATION

The oil drains faster if the upper closing elements, such as oil dipstick [2], breather [3] or screw plugs [4] are removed and when the oil change is performed when the gear unit is warm.
  1. WARNING! Risk of burns due to hot gear unit and hot gear unit oil. Severe injuries. Allow the gear unit to cool down below 50 °C before you start working on it.
  2. Remove the oil drain plug(s). Open the oil drain [1].
  3. Place a suitable container underneath the oil drain plug(s) or oil drain valve [1].
  4. Drain all the oil into the container.
  1. Clean the magnetic oil drain plug, if available.
  1. Close the oil drain [1] again.
  1. Open the oil fill plug. Observe the mounting position and the following notes:
Mounting positions M1 and M3:
  1. Open at least one of the screw plugs [6] located on the side in the upper fifth (marked gray) of the gear unit housing.
Mounting positions M2 and M4:
  1. Open at least one of the screw plugs [6] on the top or at least one of the screw plugs [6] located on the side in the upper fifth (marked gray) of the gear unit housing.
Mounting position M5 and M6:
  1. Open all accessible screw plugs [6] on the top of the gear unit housing and all accessible screw plugs located on the side in the upper fifth (marked gray) of the gear unit housing.
  1. Fill in oil of the same type through one of the housing openings [6] or the oil expansion tank [5]. If oil leaks from an opening, close the opening and keep filling the gear unit until the specified oil level is reached in the oil expansion tank [5].

    2. INFORMATION

    Preheating the oil to max. 40 °C accelerates the filling process. You may also use a pump to fill the gear unit. During the filling process, the oil level in the oil expansion tank must never increase to a point that oil leaks from the oil expansion tank into the breather pipes.
  2. Check the breather [3] for proper functioning before you install it.
  3. Screw in the oil dipstick [2].
  4. Start up the gear unit.
  5. Check the oil level at least every 30 minutes until the operating temperature is reached. If necessary, fill in additional oil.
  6. Let the gear unit cool down to a temperature between 20 °C and 40 °C and check the oil level again. Add oil if necessary.
  1. CAUTION! Danger due to leakage of lubricant. Possible risk of slipping. Immediately remove any oil that has escaped with oil binder.

INFORMATION

During the first operating hours, air pockets loosen from the gear unit and escape through the breather, so that the oil level needs to be checked.
