Safety Notes

This charger is not intended for use by children and persons with physical, sensory or mental limitations or a lack of experience or knowledge. This charger can be used by children aged 8 and above and by persons who have physical, sensory or mental limitations or a lack of experience or knowledge if a person responsible for their safety supervises them or has instructed them in the safe operation of the charger and they understand the associated dangers. Otherwise, there is a danger of operating errors and injuries.
Supervise children during use, cleaning and maintenance. This will ensure that children do not play with the charger.
Charge only Bosch lithium-ion batteries with a capacity of at least 1.3 Ah (1 battery cell or more). The battery voltage must match the battery charging voltage of the charger. Do not charge any non-re-chargeable batteries. Otherwise, there is a danger of fire and explosion.
Keep the battery charger away from rain or moisture. Penetration of water in the battery charger increases the risk of an electric shock.
Keep the battery charger clean. Contamination can lead to the danger of an electric shock.
Before each use, check the battery charger, cable, and plug. If damage is detected, do not use the battery charger. Never open the battery charger yourself. Have repairs performed only by a qualified technician and only using original spare parts. Damaged battery chargers, cables, and plugs increase the risk of an electric shock.
Do not operate the battery charger on easily inflammable surfaces (e. g., paper, textiles, etc.) or surroundings. The heating of the battery charger during the charging process can pose a fire hazard.
In case of damage and improper use of the battery, vapors may be emitted. Ventilate the area and seek medical help in case of complaints. The vapors can irritate the spiratory system.
Do not cover the ventilation slots of the battery charger. Otherwise, the battery charger can overheat and no longer operate properly.

Products sold
Your product is fitted with a BS 1363/A approved electric plug with an internal fuse (ASTA approved to BS 1362). If the plug is not suitable for your socket outlets, it should be cut off and an appropriate plug fitted in its place by an authorised customer service agent. The replacement plug should have the same fuse rating as the original plug. The severed plug must be disposed of to avoid a possible shock hazard and should never be inserted into the main socket elsewhere.

Operation

Starting Operation

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.

Charging Procedure
The charging procedure starts as soon as the mains plug of the battery charger is plugged into the socket outlet and battery 1 is inserted into the charging compartment 3.
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.
Note: The charging procedure is only possible when the battery temperature is within the allowable charging temperature range, see the “Technical Data” section.

Meaning of the Indication Elements

Flashing Battery Charge Indicator 2
The charging procedure is signaled by a flashing battery charge indicator 2.

Continuous Lighting of the Battery Charge Indicator 2 Continuous lighting of the battery charge indicator 2 indicates that the battery is fully charged or that the temperature of the battery is not within the allowable charging temperature range, and cannot be charged for this reason. The battery is charged as soon as the allowable charging temperature range is reached.

When the battery is not inserted, continuous lighting of the battery charge indicator 2 indicates that the mains plug is inserted in the socket and that the battery charger is ready for operation.

Troubleshooting – Causes and Corrective Measures

Cause/Corrective Measure

Continuous lighting of the battery charge indicator 2 No charging procedure possible

Battery not (properly) insert-ed Properly insert the battery into the battery charger
Battery contacts contaminated Clean the battery contacts (e.g. by inserting and removing the battery several times) or replace the battery
The battery pack is defective Replace the battery

Battery charge indicator 2 does not light up

The mains plug of the battery charger not plugged in (properly) Insert mains plug (fully) into the socket outlet
The socket outlet, mains cable or battery charger is defective Check the mains voltage; have the battery charger checked by an authorised after-sales service agent for Bosch power tools.

Working 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.
