d) In case of incorrect use, fluid may escape from the battery. Avoid contact with it. If you touch it by
accident, rinse the affected area with water. If you get the fluid in your eyes, also seek medical
advice. Leaking battery fluid can cause skin irritation or burns.
e) Never use damaged or altered rechargeable batteries. Damaged or altered rechargeable batteries
can behave unpredictably and lead to a risk of fire, explosion or injury.
f) Never expose a rechargeable battery to fire or high temperatures. Fire or temperatures over 130°C
pose a risk of explosion.
g) Follow all the instructions on charging and never charge the rechargeable battery or cordless tool
outside the specified allowable charging temperature range. Incorrect charging or charging outside
the allowable charging temperature range could cause irreparable damage to the battery and
increase the risk of fire.
Additional safety instructions
We pay a great deal of attention to the design of every battery pack to ensure that we supply you
with batteries which feature maximum power density, durability and safety. The battery cells have a
wide range of safety devices. Each individual cell is initially formatted and its electrical characteris-
tic curves are recorded. These data are then used exclusively to be able to assemble the best
possible battery packs. Despite all the safety precautions, caution must always be exercised when
handling batteries. The following points must be obeyed at all times to ensure safe use.
Safe use can only be guaranteed if undamaged cells are used. Incorrect handling can cause cell
damage.
Important:
Analyses confirm that incorrect use and poor care are the main causes of the damage
caused by high performance batteries.
Information about the battery
1. The battery pack supplied with your cordless tool is not charged. The battery pack has to be
charged before you use the tool for the first time.
2. For optimum battery performance avoid low discharge cycles. Charge the battery pack frequent-
ly.
3. Store the battery pack in a cool place, ideally at 15°C and charged to at least 40%.
4. Lithium-ion batteries are subject to a natural ageing process. The battery pack must be replaced
at the latest when its capacity falls to just 80% of its capacity when new. Weakened cells in an aged
battery pack are no longer capable of meeting the high power requirements and therefore pose a
safety risk.
5. Do not throw battery packs into an open fire. There is a risk of explosion!
6. Do not ignite the battery pack or expose it to fire.
7. Do not exhaustively discharge batteries. Exhaustive discharge will damage the battery cells. The
most common cause of exhaustive discharge is lengthy storage or non-use of partly discharged
batteries. Stop working as soon as the performance of the battery falls noticeably or the electronic
protection system triggers. Place the battery pack in storage only after it has been fully charged.
8. Protect batteries and the tool from overloads. Overloads will quickly result in overheating and cell
damage inside the battery housing without this overheating actually being apparent externally.
9. Avoid damage and shocks. Replace batteries which have been dropped from a height of more
than one meter or which have been exposed to violent shocks without delay, even if the housing of
the battery pack appears to be undamaged. The battery cells inside the battery may have suffered
serious damage. In this respect, please also read the waste disposal information.
10. If the battery pack suffers overloading and overheating, the integrated protective cut off will
