Working Advice - Bosch Rotak 32 LI Original Instructions Manual

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.
With no battery inserted, continuous lighting of the green
charge control LED indicates that the mains plug is plugged
into the socket and that the battery charger is ready for oper-
ation.
Battery Temperature below 0 °C or above 45 °C

Continuous lighting of the red LED indicates that the bat-
tery temperature is not within the rapid-charging temperature
range of 0 °C – 45 °C. As soon as the allowable temperature
range is reached, the battery charger automatically switches
to rapid charging.
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 procedure is pre-
sent, this will be indicated through flashing of the red charge
control LED .
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 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.
Observe the notes for disposal.
Battery Cooling (Active Air Cooling)
The fan control integrated in the battery charger controls the
temperature of the inserted battery. When the battery tem-
perature is above 30 °C, a fan cools down the battery to the
optimal charging temperature. The switched-on fan produces
a fan noise.
Bosch Power Tools
The battery temperature is within the optimal charging tem-
perature range when the fan is not running. Another reason
for a non working fan might be that it is defective. In this case,
the charging time of the battery might be extended.

Battery Charge-control Indication
The battery is equipped with a charge-control indicator
which indicates its charge condition. The charge-control indi-
cator consists of 3 green LEDs.
Press the button to actuate the charge-control indicator . Af-
ter approx. 5 seconds, the charge-control indicator goes out
automatically.
The charge condition can also be checked when the battery is
removed.
LED Indicators
Continuous lighting of 3 green LEDs
Continuous lighting of 2 green LEDs
Continuous lighting of 1 green LED
Flashing of 1 green LED
When no LED lights up after actuating the button , 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 LEDs go out again approx. 5 minutes after the battery
has been fully charged.
Temperature Control Indicator
The red LED signals that the battery or the electronics of the
garden product (with battery inserted) are not within the op-
timum temperature range. When this occurs the garden prod-
uct will not operate or not at full capacity.
Temperature Control of the Battery
The red LED flashes when you press the button or the On/Off
switch (with battery inserted): The battery is outside of the
permitted operating temperature range.
The battery switches off at a temperature above 70 °C until
the optimum temperature range is reached again.
Temperature Control of the Garden Product Elec-
tronics
The red LED lights up continuously when pressing the
On/Off switch : The temperature of the garden product elec-
tronics is below 5 °C or above 75 °C.
At a temperature above 90 °C, the electronics of the garden
product switch off until the temperature is within the allowa-
ble temperature range again.
