Safe use can only be guaranteed if undam-
aged cells are used. Incorrect handling can
cause cell damage.
Important: Analyses conrm 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 rst
time.
2. For optimum battery performance avoid low
discharge cycles. Charge the battery pack
frequently.
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 require-
ments and therefore pose a safety risk.
5. Do not throw battery packs into an open re.
There is a risk of explosion!
6. Do not ignite the battery pack or expose it to
re.
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 over-
loads.
Overloads will quickly result in overheating
and cell damage inside the battery housing
without this overheating actually being appa-
rent 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 bat-
tery pack appears to be undamaged. The bat-
tery cells inside the battery may have suered
serious damage. In this respect, please also
read the waste disposal information.
10. If the battery pack suers overloading and
overheating, the integrated protective cut-o
will switch o the equipment for safety rea-
sons. Important. Do not press the ON/OFF
switch any more if the protective cut-o has
actuated. This may damage the battery pack.
11. Use only original battery packs. The use of
other batteries may result in injuries, explo-
sion and a re risk.
Information on chargers and the charging
process
1. Please check the data marked on the rating
plate of the battery charger. Be sure to con-
nect the battery charger to a power supply
with the voltage marked on the rating plate.
Never connect it to a dierent mains voltage.
2. Protect the battery charger and its cable
from damage and sharp edges. Have
damaged cables repaired without delay by a
qualied electrician.
3. Keep the battery charger, batteries and the
cordless tool out of children’s reach.
4. Do not use damaged battery chargers.
5. Do not use the supplied battery charger to
charge other cordless tools.
6. In heavy use the battery pack will become
warm. Allow the battery pack to cool to room
temperature before commencing with the
charging.
7. Do not over-charge batteries.
Do not exceed the maximum charging times.
These charging times only apply to dis-
charged batteries. Frequent insertion of a
charged or partly charged battery pack will
result in over-charging and cell damage. Do
not leave batteries in the charger for days on
end.
8. Never use or charge batteries if you
suspect that the last time they were
charged was more than 12 months
previously. There is a high probability that
the battery pack has already suered dange-
rous damage (exhaustive discharge).
9. Charging batteries at a temperature below
10°C will cause chemical damage to the cell
and may cause a re.
10. Do not use batteries which have heated du-
ring the charging process, as the battery cells
may have suered dangerous damage.
11. Do not use batteries which have suered
curvature or deformation during the charging
process or which show other non-typical
symptoms (gassing, hissing, cracking,…)
12. Never fully discharge the battery pack (re-
commended depth of discharge max. 80%)
A complete discharge of the battery pack will
