WARNING!
Use protective gloves while handling oil.
The front bearing oil must be changed after the first 20 hours of driving and
then after every 500 hours or once every driving season.
Before you start changing the oil, make sure you have a container for draining
the used oil.
Changing the oil:
1. Open the reservoir cap and stir the oil inside.
Impurities are easier to remove from the reservoir when they are mixed in
with the oil.
2. Open the drain plug (figure 14, point A) and drain the oil into the
container.
3. Clean the plug magnet, close the drain plug and fill the reservoir
with new oil. Oil recommendations can be found in appendix 3.

This prevents air from drifting into the system and ensures that lubrication
functions well from the start. If there are particularly large amounts of
impurities in the oil, such as metal particles, the entire system must be
drained and cleaned first. In this case the bearings must also be replaced.
Only then should the new oil be poured into the system.
4. Remove the reservoir return hose (figure 14, point B) and keep it below
the reservoir.
This way the oil drains out from the bearing housing and the hoses and
the system fills up with new oil. The time it takes to drain the oil depends
on how far the reservoir is from the bearing housing. The colour of the oil
indicates whether all the old oil has drained out. The system can have a
maximum volume of up to 1 L, depending on the length of the hoses.
5. Attach the oil return hose to the reservoir once the system is filled with
new oil.
6. Check the oil level from the dipstick on the reservoir cap (figure 20, point
B) .
When the shaft starts to rotate, the system generates pressure into the
return line, causing oil to start circulating in the system.
4.3.2. Lubrication of the rear end bearing
The propulsion unit's rear end bearing is either water or grease lubricated,
depending on the model.
