The charge condition can also be checked when the battery
is removed.
LED Indication
Battery Capacity
Continuous lighting of 3
≥ 2/3
green LEDs
Continuous lighting of 2
≥ 1/3
green LEDs
Continuous lighting of 1
≤ 1/3
green LED
Flashing of 1 green LED
Reserve
When no LED lights up after pressing the button, then the
battery is defective and must be replaced.
For safety reasons, the charge condition of the battery can
only be checked when the garden product is at a standstill.
During the charging procedure, the three green LEDs light up
one after the other and briefly go out. The battery is fully
charged when the three green LEDs light up continuously.
The three green LEDs go out again approx. 5 minutes after
the battery has been fully charged.
Meaning of the Indication Elements of the
charger (AL 3640 CV/AL 36V-20)
Rapid-charging Procedure
The rapid-charging procedure is indicated by
flashing of the green battery charge indicator.
Indication element of the battery: During the
charging procedure, the three green LEDs light up one after
the other and briefly go out. The battery is fully charged
when the three green LEDs light up continuously. The three
LEDs go out again approx. 5 minutes after the battery has
been fully charged.
Note: The rapid-charging procedure is only possible when
the battery temperature is within the allowable charging
temperature range, see section "Technical Data".
Battery charged
Continuous lighting of the green LED indic-
ator indicates that the battery is fully charged.
Additionally, a signal tone sounds for approx.
2 seconds, which acoustically indicates that the battery is
fully charged.
Afterwards, the battery can be removed for immediate use.
When the battery is not inserted, continuous lighting of the
LED indicator indicates that the mains plug is inserted in the
socket outlet and that the battery charger is ready for opera-
tion.
Battery Temperature below 0°C or above 45°C
Continuous lighting of the red LED 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.
Bosch Power Tools
When the battery is not within the allowable temperature
range, the red battery LED lights up when inserting the bat-
tery into the battery charger.
No Charging Procedure Possible
If a different malfunction of the charging pro-
cedure is present, this will be indicated
through flashing of the red LED indicator.
The charging procedure cannot be started and the battery
cannot be charged (see section Troubleshooting).
Charging Advice
With continuous or several repetitive charging cycles without
interruption, the charger can warm up. This is not meaning-
ful and does not indicate a technical defect of the battery
charger.
A significantly reduced working period after charging indic-
ates that the battery is used and must be replaced.
Observe the notes for disposal.
Battery Cooling (Active Air Cooling)
The fan control integrated into the charger monitors the tem-
perature of the inserted battery. When the battery temperat-
ure is above 30 °C, a fan cools down the battery to the op-
timal charging temperature. The fan generates a ventilation
sound when switched on.
If the fan is not running, the battery temperature is within the
optimum charge-temperature range or the fan is defective.
In this case, the charging time of the battery might be exten-
ded.
Operation
Switching On and Off (see figure C)
To switch ON, firstly press and hold the lock-off button for
On/Off switch (3). Then press the On/Off switch (2) and
keep it pressed.
To switch OFF, release the lock-off button for On/Off switch
(3) and then release the On/Off switch (2).
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.
Working with the Hedgecutter (see figure D)
Move the hedgecutter evenly forward along the cutting line.
The double edge cutting blade enables cutting in either dir-
ection, or with a side to side motion.
Cut the sides of the hedge first, then the top.
To cut the sides straightly, we recommend cutting from bot-
tom to top in the direction of growth. Younger stems tend to
move outwards when cutting them from top to bottom, res-
ulting in shallow patches or holes in the hedge.
To reach a level finish, fasten a piece of string along the
length of the hedge at the required height and use as an
alignment guide. Cut the hedge just above the string.
