(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.

Table 2

Recharging ranges of batteries

(3) Regarding recharging time

Depending on the combination of the charger and
batteries, the charging time will become as shown
in 

Table 3

.

Table 3

  Charging time (At 20°C)

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.

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

䡬

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.

䡬

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.

䡬

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. Mounting the drill bit (Fig. 5, 6)
CAUTION

To prevent accidents, make sure to turn the switch
off.

NOTE:

When using tools such as drill bits, etc., make sure
to use the genuine parts designated by our company.

(1) Clean the shank portion of the drill bit.
(2) Insert the drill bit in a twisting manner into the tool

holder until it latches itself. (

Fig. 5

)

The grip need not be adjusted during bit installation.

(3) Check the latching by pulling on the drill bit.
(4) To remove the drill bit, fully pull the grip in the

direction of the arrow and pull out the drill bit.

2. Confirm that the battery is mounted correctly.
3. Installation of dust cup or dust collector (B) (Optional

accessories) (Fig. 7, Fig. 8)
