c) Do not disassemble, squash or incinerate bat-
teries and do not subject them to temperatures
over 80°C. A risk of fire, explosion or injury
through contact with caustic substances may
otherwise result.
d) Avoid ingress of dampness.Dampness may
cause a short circuit resulting in a risk of burning
en
injury or fire.
e) Do not use batteries other than those approved
for use with the applicable tool or appliance.
Use of other batteries or use of the battery for
purposes for which it is not intended presents a
risk of fire and explosion.
f) Observe the special instructions applicable to
the transport, storage and use of Li-ion batter-
ies.
g) Avoid short-circuiting the battery.Before insert-
ing the battery in the tool or appliance, check
that the terminals of the battery and the tool or
appliance are free from foreign objects. Short-
circuiting the battery terminals presents a risk of
fire, explosion or contact with caustic substances.
h) Do not charge or continue to use damaged bat-
teries (e.g. batteries with cracks, broken parts,
bent or pushed-in and/or pulled-out contacts).
6. Before use
6.1 Battery use and care
NOTE
Use a battery only when it has been fully charged.
This ensures that maximum battery capacity is avail-
able. Change to the second battery as soon as a
drop in performance is noticed. Recharge the battery
immediately so that it is ready for reuse.
Battery performance drops at low temperatures. For
optimum results it is recommended that the items to
be used are at room temperature before work begins.
The battery must be kept warm, i.e. within its normal
operating temperature range, when working outdoors
in low temperatures.
