BATTERY & CHARGER INSTRUCTIONS
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. Incor-
rect handling of the battery pack can cause cell damage.
ABOUT THE BATTERY
1. The battery pack supplied with your cordless tool is
only partially charged. The battery pack has to be charged
completely before you use the tool for the first time.
2. For optimum battery performance, avoid low dis-
charge cycles by charging the battery pack frequently.
3. Lithium-ion batteries are subject to a natural aging
process. The battery pack must be replaced at the lat-
est 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 needed for the proper operation of your tool, and
therefore pose a safety risk.
4. Do not throw battery packs into an open fire as this
poses a risk of explosion. Do not ignite the battery pack
or expose it to fire.
5. Do not exhaustively discharge batteries. Exhaustive
discharge will damage the battery cells. The most com-
mon cause of exhaustive discharge is lengthy storage or
non-use of partially discharged batteries. Stop working
as soon as the performance of the battery falls notice-
ably or the electronic protection system triggers. Place
the battery pack in storage only after it has been fully
charged.
6. Protect batteries and the tool from overloads. Over-
loads will quickly result in overheating and cell damage
inside the battery housing even if this overheating is not
apparent externally.
7. Avoid damage and shocks. Immediately replace bat-
teries that have been dropped from a height of more than
one meter or those that have been exposed to violent
shocks, even if the housing of the battery pack appears
to be undamaged. The battery cells inside the battery
may have suffered serious damage. In such instances,
please read the waste disposal information for proper
battery disposal.
WARNING! Waste electrical products should
not be disposed of with household waste. Please
recycle where facilities exist. Check with your local
authority or retailer for recycling advice.
8. If the battery pack suffers overloading and overheat-
ing, the integrated protective cutoff will switch off the
equipment for safety reasons.
9. Use only original battery packs. The use of other bat-
teries poses a fire risk and may result in injuries or an
explosion.
CHARGER
Protect the battery charger and its cord from damage.
Keep the charger and its cord away from heat, oil and
sharp edges. Electrical plugs must match the outlet.
Never modify the plug in any way. Do not use any adapter
plugs with grounded appliances. Unmodified plugs and
matching outlets will reduce the risk of electric shock.
Keep the battery charger, battery pack(s) and the cord-
less tool out of the reach of children. Do not use the
supplied battery charger to charge other cordless tools.
During periods of heavy use, the battery pack will be-
come warm. Allow the battery pack to cool to room tem-
perature before inserting it into the charger to recharge.
Do not overcharge batteries. Do not exceed maximum
charging times. These charging times only apply to dis-
charged batteries. Frequent insertion of a charged or
partially charged battery pack will result in overcharging
and cell damage. Do not leave battery in the charger for
days on end. Never use or charge a battery if you sus-
pect that it has been more than 12 months since the last
time they were charged. There is a high probability that
battery pack has already suffered dangerous damage
(exhaustive discharge). Do not use battery that has been
exposed to heat during the charging process, as the bat-
tery cells may have suffered dangerous damage. Do not
use battery that has suffered curvature or deformation
during the charging process or those that exhibit other
atypical symptoms (gassing, hissing, cracking, etc.)
