(2) Regarding the temperatures of the rechargeable
battery
The temperatures for rechargeable batteries are as
shown in Table 2, and batteries that have become hot
should be cooled for a while before being recharged.

(3) Regarding recharging time
Depending on the combination of the charger and
batteries, the charging time will become as shown in
Table 3.

NOTE
The charging time may vary according to temperature
and power source voltage.
4. Disconnect the charger's power cord from the
receptacle.
5. Hold the charger firmly and pull out the battery.
NOTE
After operation, pull out batteries from the charger first,
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 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
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 continuosly 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 map light in green.
The battery will not be recharged. In such a case, let the
battery cool before charging.
○ When the pilot lamp flickers in red (at 0.2-second
intervals), check for and take out any foreign objects
in the charger's battery installation hole. If there are no
foreign objects, it is probable that the battery or charger is
malfunctioning. Take it to your authorized Service Center.
PRIOR TO OPERATION
1. Setting up and checking the work environment
Check if the work environment is suitable by following
the precautions.
2. Preparing the screws
Select screws appropriate to the application.
3. Bit checking and replacement
A No. 2 Plus bit is installed on this machine as a
standard accessory. Always inspect the bit to make
sure it is not damaged. Using worn bits can cause
screw-in malfunctions. Inspect the bit before work
and quickly replace it with a new one when it starts
to wear out. When the bit must be replaced due to bit
damage or any other reason, replace it according to the
instructions in Bit installation and removal.
Malfunction in the battery or the
charger
Battery overheated.
Unable to charge.
(Charging will commence when
battery cools)
