Adjusting the Carburettor
The carburettor is preset in the factory for
optimal performance. If subsequent adjust-
ments are required, have them carried out
by a specialist workshop.
Removing blockages
Switch the device off and re-
move the spark plug connec-
tor before you work on the
cutting unit.
Wear protective gloves in order to
avoid cutting yourself.
Checking the coupling
Place the device on a irm level sur
-
face. Make sure that the cutting tool
does not touch either other objects
or the ground.
Before each use, check that the coupling is
working correctly when idling.
Start the device (see “Starting the en-
gine”) and carry out a visual check at a
suficiently safe distance to verify that the
thread spool is not turning when the device
is idling.
Maintenance Intervals
Regularly carry out the maintenance work
listed in the “maintenance intervals” table.
Regular maintenance prolongs the life of
the equipment. It also gives optimum cut-
ting performance and avoids accidents.
