Inspection, filling and drain screws are located in the same positions on the front and rear axles.

The complete axle has a common oil system. The transfer case has a common oil system. You can check the oil level
at the differential housing and at the transfer case.
1. Park the loader on a horizontal surface and apply the parking brake.
2. Lower the lifting frame completely.
3. Switch off the engine.
4. Unscrew the Allen screws.
5. The transmission oil must be at the lower edge of the filler opening.

ENVIRONMENTAL INFORMATION
Do not harm the environment! Collect old transmission oil and dispose of it in an environmentally friendly manner.
Axle oil replacement
Scalding hazard due to hot transmission oil!
Use a sufficiently dimensioned drip tray to collect the old transmission oil and use the correct oil type. The
transmission oil is viscous! Replace the axle oil when it is warm and open the fill screw; it then drains faster!
1. Park the loader on a horizontal surface and apply the parking brake.
2. Lower the lifting frame completely.
3. Switch off the engine.
4. Place a sufficiently dimensioned drip tray beneath the transfer case drain plug.
5. Unscrew the Allen screws; the transmission oil then drains faster.
When the transmission oil has drained
1. Refit the Allen screws.
2. Fill new transmission oil through the filler opening.
3. The transmission oil must be at the lower edge of the filler opening.
4. Refit the Allen screws.
5. Check the oil level at the transfer gear case and differential case again after half an hour of operation and top
up the transmission oil if necessary.
