Regarding the temperature of the rechargeable
battery.
The temperatures for rechargeable batteries are
as shown in the table below, and batteries that
have become hot should be cooled for a while
before being recharged.

Regarding recharging time
Table 3 shows the recharging time required
according to the type of battery.

NOTE:
The recharging time may vary according to the
ambient temperature and the power supply
voltage.
4.
Disconnect battery charger from the receptacle.
CAUTION:
Do not pull the plug out of the receptacle by pulling
on the cord.
Make sure to grasp the plug when removing from
receptacle to avoid damaging cord.
5.
Remove the battery from the battery charger.
Supporting the battery charger with hand, pull out
the battery from the battery charger.
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.
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.

Temperatures at which the
battery can be recharged

40 min.
Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately
after use. If such a battery is recharged immediately
after use, its internal chemical substance will
deteriorate, and the battery life will be shortened.
Leave the battery and recharge it after it has cooled
for a while.
CAUTION:
●
When the battery charger has been continuously
used, the battery charger will be heated, thus
constituting the cause of the failures. Once the
charging has been completed, give 15 minutes rest
until the next charging.
●
If the battery is recharged when it is warm due to
battery use or exposure to sunlight, the pilot lamp
may not light.
The battery will not be recharged. In such a case,
let the battery cool before charging.
●
If the battery charger does not work while the
battery is mounted correctly, it is probable that
the battery or charger is malfunctioning. Take it
to your authorized Service Center.
FUNCTIONAL DESCRIPTION
Battery level warning lamp
The battery level can be checked by pulling the
trigger switch while the power tool is in a no-load
state. The battery level warning lamp lights when
the battery power is very low. If this happens,
charge the battery. (Fig. 5)
NOTE:
The level at which the battery level warning lamp
lights may vary due to the ambient temperature,
characteristics of the battery, etc. and is intended
only as a guide.
The battery level warning lamp may light when
the power tool is overloaded. This does not mean
that the battery power is very low.
Be sure to check the battery level while the tool is
in a no-load state.
