Anti Blocking

This tool has the anti-blocking system installed for your
benefit. If the blade stalls on a tough material, the load of the
motor increases. The intelligent micro-electronics senses this
overload 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
normal 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).
