4. Hold the charger fi rmly and pull out the battery.
NOTE
After operation, pull out batteries from the charger fi rst, and then keep the batteries
properly.
Regarding electric discharge in case of new batteries, etc.
As the internal chemical substance of new batteries and batteries that have not been used
for an extended period is not activated, the electric discharge might be low when using
them the fi rst and second time. This is a temporary phenomenon, and normal time required
for recharging will be restored by recharging the batteries 2 – 3 times.
How to make the batteries perform longer
(1) Recharge the batteries before they become completely exhausted.
When you feel that the power of the tool becomes weaker, stop using the tool and recharge
its battery. If you continue to use the tool and exhaust the electric current, the battery may
be damaged and its life will become shorter.
