Continuous Lighting of the Red Battery Charge
Indicator
Continuous lighting of the red battery charge
indicator indicates that the temperature of the
battery is not within the allowable charging temperature
range, see section "Technical Data". As soon as the allowable
charging temperature range is reached, the battery charger
automatically switches to rapid charging.
Flashing Red Battery Charge Indicator
A flashing red battery charge indicator indi-
cates a different malfunction of the charging
procedure, see section "Troubleshooting".
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.

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.

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).
