13 Air Filter System
13.1 Basic information
The average filter life is more than 1 year. Do not
dismantle the filter cover or fit a new air filter
unless there is a noticeable loss of engine
power.
In the long-life air filter system with the cyclone
pre-separation system, dirty air is drawn in and
deliberately rotated. The larger and heavier parti‐
cles carried in the air are thus expelled and
extracted. Only pre-cleaned air enters the air fil‐
ter system and the result is extremely long filter
life.
