NOTE: A short or worn trimming line will not cut well. If you notice reduced cutting performance,
you should check if there is enough trimming line on the spool. Remove the battery pack
before inspection. For spool replacement, refer to the Spool Replacement instructions in the
Maintenance section.
This trimmer is equipped with an automatic single line mechanism. To release more line, start and
stop the trimmer 2 - 3 times.
The trimming line extends automatically during every starting process. For the correct functioning
of the automatic line extension mechanism, the spool must stop completely before you restart
the trimmer. If the trimming line is initially longer than the cutting diameter, it is automatically
shortened to the right length by the line cutting blade.
NOTE: Regularly check the trimming line for damage and whether the line still has the correct
