Battery Charging
 Do not use other battery chargers. The supplied battery
charger is designed for the Lithium-Ion battery in your gar-
den product.
 Observe the mains voltage! The voltage of the power
supply must correspond with the data given on the name-
plate of the battery charger. Battery chargers marked with
230 V can also be operated with 220 V.
The battery is equipped with temperature monitoring that al-
lows charging only in the temperature range between 0 °C
and 45 °C. In this manner, a high battery service life is
achieved.
Note: The battery is supplied partially charged. To ensure full
capacity of the battery, completely charge the battery in the
battery charger before using your power tool for the first time.
The lithium ion battery can be charged at any time without re-
ducing its service life. Interrupting the charging procedure
does not damage the battery.
The "Electronic Cell Protection (ECP)" protects the lithium ion
battery against deep discharging. When the battery is run
down or discharged, the garden product is shut off by means
of a protective circuit: The garden product no longer operates.
Do not continue to press the On/Off
switch after the garden product has
been automatically switched off. The battery can be dam-
aged.
Charging Procedure
The charging procedure starts as soon as the mains plug is
plugged into the socket and the battery is then inserted into
the battery charger .
Firstly, place the battery as shown in the figure onto the front
of the battery charger () and then press the battery down
at the rear (). To remove the battery, proceed in reverse or-
der.
Due to the intelligent charging method, the charging condi-
tion of the battery is automatically detected and the battery is
charged with the optimum charging current, depending on
battery temperature and voltage.
This gives longer life to the battery and always leaves it fully
charged when kept in the charger for storage.

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.
Problem Possible Cause
Hedgecutter does not op- Battery discharged
erate
Safety switch not activated correctly
Hedgecutter operates in- Internal wiring of garden product damaged
termittently
On/Off switch defective
Motor reverses repeatedly then stalls after 3 s. see "Working Advice" (Anti Blocking)
F 016 L81 044 | (5.2.14)
Note: The charging procedure is only possible when the bat-
tery temperature is within the allowable charging tempera-
ture range, see section "Technical Data".
Flashing Battery Charge Indicator
The charging procedure is signalled by a
flashing battery charge indicator .
Continuous Lighting of the Battery Charge Indica-
tor
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 charger.
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
The garden product has a patented feature which works as
follows:
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).
