Starting Operation

For Your Safety

  • Warning! Switch off, remove the isolator switch and the battery before adjusting or cleaning. The same applies when the cable to the switch in the handle is damaged, cut or entangled.
  • The blade continues to rotate for a few seconds after the machine is switched off.
  • Caution: Do not touch the rotating blade.
Charging the Battery

The battery is equipped with temperature monitoring that allows charging only in the temperature range between 0 °C and 35 °C. In this manner, a high battery service life is achieved.

Note: The battery is supplied partially charged. To ensure full battery capacity, completely charge the battery in the battery charger before using 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 cause damage to the battery.
The “Electronic Cell Protection (ECP)” protects the lithiumion battery against deep discharging. When the battery is empty, the product is switched off by means of a protective circuit: The product no longer operates.
Do not continue to press the On/Off switch after an automatic shut-off of the product. The battery could become damaged.
Observe the notes for disposal of the battery.

Inserting/Removing the Battery

Note: Using unsuitable batteries can lead to malfunctions or damage the machine.

Insert the charged battery. Ensure the battery is inserted correctly.

To remove the battery from the machine, press the battery unlocking button and pull the battery out.

Charging Procedure

The charging procedure starts as soon as the mains plug of the charger is plugged into a socket outlet and the battery is inserted onto the charger .
Due to the intelligent charging method, the charging condition 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.

Meaning of the indication elements on the charger (AL 3620 CV/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 indicator 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 operation.

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.
When the battery is not within the allowable temperature range, the red battery LED lights up when inserting 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 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 meaningful and does not indicate a technical defect of the battery charger.
A significantly reduced working period after charging indicates 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 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 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 extended.

Working Advice

Battery charge-control indicator

The battery is equipped with a charge-control indicator, which indicates its charge condition. The charge-control indicator consists of 3 green LEDs.
Press the charge-control indicator 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.

LED Indication Battery Capacity
Continuous lighting of 3 green LEDs ≥ 2/3
Continuous lighting of 2 green LEDs ≥ 1/3
Continuous lighting of 1 green LED ≤ 1/3
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.

Temperature Monitoring Indicator of the battery

The red LED of the temperature monitoring indicator signals that the battery or the electronics of the garden product (with battery inserted) are not within the optimum temperature range. When this occurs, the garden product will not operate or not at full capacity.

Temperature Monitoring of the Battery

The red LED flashes when pressing 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 allowable operating-temperature range is reached again.

Temperature Monitoring of the Garden Product’s Electronics

The red LED lights up continuously when pressing the On/Off switch: The temperature of the garden product’s 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 operating-temperature range again.

Cutting Capacity (Battery Operating Duration)

The cutting capacity (battery operating duration) depends on lawn properties, such as grass density, moisture content, grass length and height of cut.
Switching the machine on and off frequently during cutting will also reduce the cutting capacity (battery operating duration).

To improve the cutting capacity (battery operating duration), it is recommended to cut more frequently, increase the cutting height and walk at an appropriate pace.

The example below shows the connection between cutting height and cutting capacity with regard to three batteries.

Cutting Conditions
Very thin, dry grass
Cutting capacity  
Battery with 2.0 Ah up to 250 m2
Battery with 4.0 Ah up to 500 m2
Battery with 6.0 Ah up to 750 m2

To increase the run time an additional battery can be purchased from an authorised customer service agent for Bosch garden products.
