Continuous lighting of the green charge control LED

signals that the battery is fully charged.

Additionally, a signal tone sounds for approx.

2 seconds, which acoustically indicates that the bat-

tery 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 operation.

Battery Temperature below 0 °C and

above 45 °C

Continuous lighting of the red LED indicates that the

battery temperature is not within the rapid-charging

temperature range of 0 °C

– 45 °C. As soon as the al-

lowable temperature range is reached, the battery

charger automatically switches to rapid charging.

When the battery is not within the allowable tempera-

ture range, the red battery LED lights up when insert-

ing the battery into the battery charger.

No charging procedure possible

If a different malfunction of the charging procedure is

present, this will be indicated through flashing of the

red charge control LED.

The charging procedure cannot be started and the bat-

tery 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 de-

fect of the battery charger.

A significantly reduced working period after charging in-

dicates 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 con-

trols the temperature of the inserted battery. When

the battery temperature is above 30 °C, a fan cools

down the battery to the optimal charging temperature.

The switched-on fan produces a fan noise.

The battery temperature is within the optimal charging

temperature range when the fan is not running. Anoth-

er reason for a non working fan might be that it is de-

fective. In this case, the charging time of the battery

might be extended.

Working Advice

Battery Charge-control Indication

The battery is equipped with a charge-control indica-

tor which indicates its charge condition. The charge-

control indicator consists of 3 green LEDs.

Press the button to actuate the charge-control

indicator. After approx. 5 seconds, the charge-control

indicator goes out automatically.

The charge condition can also be checked when the

battery is removed.

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 bat-

tery 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 optimum temperature range. When this oc-

curs the garden product will not operate or not at full

capacity.

Temperature Control of the Battery

The red LED flashes when pushing button or pressing

the On/Off switch (when the battery is inserted): The

battery is not wihin the temperature range for opera-

tion of

–10 °C to +60 °C.

The battery switches off at a temperature above 70 °C

until the optimum temperature range is reached again.

Temperature Control of the Garden Prod-

uct Electronics

The red LED lights up continuously when pressing the

On/Off switch: The temperature of the garden product

electronics 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 allowable temperature range again.

Area of Cut (Battery Duration)

The area of cut (battery duration) depends on lawn

conditions, grass density, mositure content, grass

length and height of cut.

Switching the machine on and off frequently during

cutting will also reduce the area of cut (battery dura-

tion).

To improve the area of cut (battery duration) it is rec-

ommended to cut more frequently, raise the cutting

height and walk at a normal pace.

The example below shows impact of conditions

against run time, for one battery.

*with battery 2 607 336 107

To increase the run time an additional battery or high-

er capacity battery (Ah) can be purchased from an au-

thorised customer service agent for Bosch garden

products.
