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).
Troubleshooting
The following chart lists problem symptoms, possible causes and corrective action, if your garden product does not operate
properly. If these do not identify and correct the problem, contact your service agent.
Warning: Switch off and remove the battery prior to any troubleshooting.
