► Hold the brushcutter firmly with one hand on
the control handle so that your thumb wraps
around the grip of the control handle.
► Hold the brushcutter with your other hand on
the loop handle so that your thumb wraps
around the loop handle.
13.2 Setting the power level
Depending on the application, 2 power levels
can be set. The position of the power level slide
(1) shows the power level that has been set.
The selected power level affects the battery's
runtime.
–
: ECO power level, low performance
–
Maximum power level, maximum per‐
formance.
When the maximum power level is set, the
brushcutter recognizes the cutting attachment
that has been attached and automatically adjusts
the appropriate speed of the blade.
When the Eco power level is selected, the speed
is reduced.
This can extend the battery runtime.
