• Keep the battery charger, battery pack and the cordless
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 become
warm. Allow the battery pack to cool to room temperature
before connecting with the charger to recharge.
• Do not overcharge batteries. Do not exceed the maximum
charging times. These charging times only apply to
discharged batteries. Frequent insertion of a charged or
partially charged battery pack will result in overcharging
and cell damage. Do not leave batteries in the charger for
days on end.
• Never use or charge the battery if you suspect that it has
been more than 12 months since the last time they were
charged. There is a high probability that the battery pack
has already suffered dangerous damage (exhaustive
discharge).
• Charging batteries at a temperature below 41°F (5°C) will
cause chemical damage to the cells and may cause a fire.
• Do not use batteries that have been exposed to heat
during the charging process, as the battery cells may have
suffered dangerous damage.
• Do not use batteries that have suffered curvature or
deformation during the charging process or those that
exhibit other atypical symptoms (gassing, hissing,
cracking, etc.).
• Never fully discharge the battery pack (maximum
recommended depth of discharge is 80%). A complete
discharge of the battery pack will lead to premature aging
of the battery cells.
Protection from environmental influences
• Wear suitable work clothes. Wear safety goggles.
• Protect your cordless tool and the battery charger from
moisture and rain. Moisture and rain can cause dangerous
cell damage.
• Do not use the cordless tool or the battery charger near
vapors and flammable liquids.
• Use the battery charger and cordless tools only in dry
conditions and at an ambient temperature of 41ºF - 105°F
(5°C - 40.5°C).
• Do not keep the battery charger in places where the
temperature is liable to reach over 105°F (40.5°C). In
particular, do not leave the battery charger in a car that is
parked in the sunshine.
• Protect batteries from overheating. Overloads,
overcharging and exposure to direct sunlight will result
in overheating and cell damage. Never charge or work
with batteries that have been overheated – replace them
immediately, if possible.
• Store the charger and your cordless tool only in dry
locations with an ambient temperature of 41ºF - 105°F
(5°C - 40.5°C). Store your lithium-ion battery pack in a
cool, dry place at a temperature of 77°F (25°C). Protect
the battery pack, charger and cordless tool from humidity
and direct sunlight. Only place fully charged batteries in
storage (charged to at least 40%).
• Prevent the lithium-ion battery pack from freezing. Battery
packs that were stored below 32°F (0°C) for more than 60
minutes must be discarded.
• When handling batteries, be wary of electrostatic charge.
Electrostatic discharges can damage the electronic
protection system and the battery cells. Avoid electrostatic
charging and never touch the battery poles.
