Charging Advice
With continuous or several repetitive charging cycles without
interruption, the charger can warm up. This is not meaningful
and does not indicate a technical defect of the battery charg-
er.
A significantly reduced working period after charging indi-
cates that the battery is used and must be replaced.

Working Advice

Sawing Function
Although the tooth opening allows wood to be cut up to
Ø 20 mm, the tip of the blade is designed to cut wood up to
Ø 25 mm.
Anti Blocking
If the blade stalls on a tough material, the load of the motor in-
creases. The intelligent micro-electronics senses this over-
load condition and repeatedly reverses the motor, in order to
prevent stalling and to cut the material through.
This audible reversing cut action continues for up to 3 s.
After cutting through, the garden product continues in its nor-
mal mode, or in case the overload condition continues the
blades automatically stop in the open position (e. g. in case a
piece of metal fence accidentally blocks the garden product).
