thread spool.
Thread follow-up
During trimming, the cutting thread wears (becomes shorter) or
it may tear off so that it can no longer cut grass.
Shortly press the machine against solid ground. This will
extend the cutting thread (by approx. 2,5 cm). If the cutting
thread exceeds the maximum cutting diameter it will be
shortened by the integrated knife within the protective hood.
Maintenance and care
Before each maintenance and cleaning work
− Stop the engine.
− Wait until the cutting device does not longer
move.
− Remove the spark plug connector.
− Wear protective gloves in order to avoid injury
to the hands.
− Do not carry out maintenance work close to
open flames. Risk of fire!
Maintenance and repair work other than those described in this
chapter is only allowed to be carried out by service staff.
Use only original parts. Other parts can result in unexpected
damages and injuries.
For maintaining and cleaning, removed security devices must
unconditionally be mounted properly and proved again.
