Bring the engine to cutting speed before
entering the material to be cut.
If the blade does not turn when you
squeeze the throttle trigger, make sure
tube is fully inserted into the engine.
Always release the throttle trigger and
allow engine to return to idle speed
when not cutting. The blade should not
turn while the engine is running at idle. If
the blade turns at idle, do not use your
unit. Refer to the Carburetor adjustment
section or contact your Authorized Ser­
vice Dealer.
WARNING: The operator or others
must not try to clear away cut material
with the engine running or the blade
turning to avoid serious injury. Stop en­
gine and blade before removing materi­
als wrapped around blade or tube.

formance and increases fuel consump­
tion and harmful emissions. Always
clean after every 5 hours of operation.
• Clean the cover and the area around
it to keep dirt and debris from falling
into the carburetor chamber when
the cover is removed.
• Remove parts as illustrated.
• Wash the filter in soap and water.
• Allow filter to dry.
• Add a few drops of oil to the filter;
squeeze filter to distribute oil.
• Replace parts. Make sure the filter is
seated completely.
