CHARGING
Before using the power tool, charge the battery as
follows.
1. Connect the charger power cord to the receptacle
2. Insert the battery in the charger
Position the battery so that the nameplate faces
toward the nameplate of the charger and press in
the battery until it comes into contact with the
bottom plate (See Fig. 1).
Inserting the battery will turn on the charger (the
pilot lamp lights up).
CAUTION
If the pilot lamp does not light up, pull out the
power cord from the receptacle and check the
battery mounting condition.
The pilot lamp goes off to indicate that the battery
is fully charged.
CAUTION
If the battery is heated due to direct sunlight,
etc., just after operation, the charger pilot lamp
may not light. At that time cool the battery first,
then start charging.
䡬 Regarding recharging time
Table 1 shows the recharging time required
according to the type of battery.

3. Disconnect the charger’s power cord from the
receptacle
4. Hold the charger firmly and pull out the battery
NOTE
Be sure to pull out the battery from the charger
after use, and then keep it.
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 first
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.
(2) Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after
use. If such a battery is recharged immediately after
