Safety instructions
Read all the safety and general instructions.
Failure to observe the safety and general instructions may result in electric
shock, fire and/or serious injury.
Store these instructions in a safe place.
Only use the charger if you can fully evaluate all functions and carry them
out without restrictions, or if you have received corresponding instructions.
► This charger is not intended for use by children or persons with physical,
sensory or mental limitations or a lack of experience or knowledge. This
charger can be used by children aged 8 or older 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 risk of operating errors and injuries.
► Supervise children during use, cleaning and maintenance. This will ensure
that children do not play with the charger.
► Only charge Bosch Li-ion batteries with a capacity of 1.3 Ah or more. The
battery voltage must match the battery charging voltage of the charger. Do not
charge any non-rechargeable batteries. Otherwise there is a risk of fire and
explosion.
Only use the charger in enclosed spaces and do not expose it to wet
conditions. Water entering a charger increases the risk of electric shock.
► Keep the charger clean. Dirt poses a risk of electric shock.
► Always check the charge, including the cable and plug, before use. Stop
using the charger if you discover any damage. Do not open the charger
yourself, and have it repaired only by Bosch or by an authorised after-sales
service centre using only original replacement parts.
Damaged chargers, cables and plugs increase the risk of electric shock.
► Do not operate the charger on an easily ignited surface (e.g. paper,
textiles, etc.) or in a flammable environment. There is a risk of fire due to
the charger heating up during operation.
► Do not cover the ventilation slots of the charger. Otherwise, the charger
may overheat and no long function properly.
► Recharge only with the charger specified by the manufacturer.
A charger that is suitable for one type of battery pack may create a risk of
fire when used with another battery pack.
► In case of damage and improper use of the battery, vapours may also be
emitted.
Ensure the area is well-ventilated and seek medical attention should you
experience any adverse effects. The vapours may irritate the respiratory
system.
► Under abusive conditions, liquid may be ejected from the battery; avoid
contact. If contact accidentally occurs, flush with water. If liquid contacts
eyes, additionally seek medical help. Liquid ejected from the battery may
cause irritation or burns.
Products sold in GB only:
Your product is fitted with an BS 1363/A approved electric plug with 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 a mains socket elsewhere.

bay (2).
The charging process is only possible when the temperature of the battery is
within the permitted charging temperature range (0–45 °C).
