7 Operation

Charge the battery pack before use.
The battery pack reaches its full capacity only
after being charged and discharged 5 times
(charge cycles).
The maximum number of charge cycles can
only reached if an exhaustive discharge of the
battery pack is avoided. If performance dimin-
ishes, recharge the battery pack.
Store NiMH battery packs when charged and
recharge after 6 months at the latest.
Li-Ion battery packs (18 V)
have a capacity and signal display:
- Press the button and the charge level is
displayed by the LEDs.
- If one LED is flashing, the battery pack is
almost flat and must be recharged.
- If all LEDs are flashing, the electronic system
has switched off the battery pack (self-
protection mode).The battery pack is either
flat (the electronic system protects the
battery pack against exhaustive discharge),
or has become overloaded or too warm
during operation (temperature monitoring).
To continue using the battery pack: Press
the button or insert the battery pack into the
charger, which is ready for use. (Rapid
cooling is possible in the "AIR COOLED"
battery charger.)
