until you feel it engage – then give it a brisk
strong pull – do not pull out the starter rope all
the way

Do not let the starter grip snap back – it may
break! Guide it back into the housing in the
opposite direction so that it can rewind properly.

14 Air Filter System

14.1 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.
14.2 Replacing the air filter
14.2.1 Only if there is a noticeable loss of
engine power
