► Turn the high speed adjusting screw (H)
slightly clockwise (leaner) – max. up to the
stop
NOTICE
After descending from a high altitude, restore the
carburetor setting to the standard setting.
If you make the setting too lean it will increase
the risk of engine damage through lack of lubri‐
cation and overheating.

Muffler
In some countries, the mufflers are fitted with a
spark arresting screen.
WARNING
To reduce the risk of fire caused by hot particles
escaping from the machine, never operate the
machine without a spark arresting screen, or with
the spark arresting screen damaged. Do not
modify the muffler or spark arresting screen.
NOTICE
According to the law or regulations in some
countries or federal states, certain operations
may only be carried out if a properly serviced
spark arresting screen is provided.
► If the engine performance deteriorates, check
the spark arresting screen in the muffler.
WARNING
Wait for the engine to cool down completely
before performing this work.
