Working Advice (see figure J)
Anti Blocking
This tool has the anti-blocking system installed for your bene-
fit. If the blade stalls on a tough material, the load of the motor
increases. 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).
