Continuous Lighting of the Battery Charge
Indicator
Continuous lighting of the battery
charge indicator indicates that the
battery is fully charged or that the
temperature of the battery is not with-
in the allowable charging temperature range, and cannot be
charged for this reason. The battery is charged as soon as the
allowable charging temperature range is reached.
When the battery is not inserted, continuous lighting of the
battery charge indicator indicates that the mains plug is in-
serted in the socket and that the battery charger is ready for
operation.
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.

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.

F 016 L81 255 | (15.12.14)
A significantly reduced working period after charging indi-
cates that the battery is used and must be replaced.
Observe the notes for disposal.
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).
