Change axle oil

WARNING
When changing the oil, apply the parking brake and secure
the front and rear frames with the safety bar.
After the engine is stopped, the parts and oil are at high tem-
perature, and may cause burns. Wait for the temperature to
go down before starting the operation.
When the plug is removed, oil may spurt out, so turn it slowly
to release the internal pressure, then remove it carefully.
Refill capacity front: 87 liters (22.9 US gal)
Refill capacity rear: 81 liters (21.4 US gal)
To prevent the drained oil from coming into contact with the tires,
do as follows.
1. Move the machine so that drain plug (1) of the final drive is
at the top. Remove plug (1), install the nipple of the supplied
tool, then insert the hose.
2. Move the machine so that plug (1) is at the bottom, then
remove oil filler plug (2) and drain the oil through the hose.
3. Remove front and rear oil filler plugs (F), then remove level
plug (3) and drain plug (4) to drain the oil.
