Air Filter System
Basic information
The average filter life is more than
1 year. Do not disassemble the filter
cover or install 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 rotated. The larger and
heavier particles carried in the air are
expelled and extracted. Only pre-
cleaned air enters the air filter system
and the result is longer filter life.
