Starting

For Your Safety

  • Warning! Switch off, remove the isolator key and the battery before adjusting, cleaning or if cable is cut, damaged or entangled.
  • The blades continue to rotate for a few seconds after the machine is switched off.
    Caution – do not touch the rotating blade.

Battery Charging

  • Do not use other battery chargers. The supplied battery charger is designed for the Lithium-Ion battery in your garden product.
  • Observe the mains voltage! The voltage of the power supply must correspond with the data given on the nameplate 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 allows 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 reducing 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 blade no longer moves.

WARNING
Do not continue to press the On/Off switch after the garden product has been automatically switched off. The battery can be damaged.

Charging Procedure
The charging procedure starts as soon as the mains plug of the battery charger is plugged into the socket outlet and the battery is inserted into the charging compartment.
Due to the intelligent charging method, the charging condition of the battery is automatically detected and the battery is charged with the optimum charging cur-rent, 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.

Rapid-charging Procedure

The rapid-charging procedure is indicated by flashing of the green charge control LED.
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”.

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 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 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.

BOSCH-34-LI-Rotak-Lawn-Mower-FIG-24

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 Product 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 duration). 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.
