Procedure

1. First remove either the dipstick or the filler cap, dependent on the gearbox model.
2. Position the hose of the special sump pump into the pipe of the dipstick.
3. Extract the oil from the gearbox by quickly pushing down the grip of the sump pump and then pull it slowly upwards.
4. If there is sufficient space below the bottom of the gearbox, you may also remove the drain plug of the gearbox for letting the oil out.
5. In both cases collect the oil in a bowl and treat it in accordance with the environmental directives in your country.
6. Fill the gearbox with its lubricant through the hole of the dipstick, or via the filler cap, if available (dependent on the model of gearbox).
