Air Filter System
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 particles carried in
the air are thus expelled and extracted.
Only pre-cleaned air enters the air filter
system and the result is extremely long
filter life.
Replacing the air filter
Only if there is a noticeable loss of
engine power
