NOTE
The recharging time may vary according to the ambient
temperature and power source voltage.
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.
4. Disconnect the charger's power cord from the
receptacle.
5. Hold the charger fi rmly 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 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.
(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
○ If the battery is charged while it is heated because it has
been left for a long time in a location subject to direct
sunlight or because the battery has just been used,
the pilot lamp of the charger lights up green or lights
for 1 second, does not light for 0.5 seconds (off for
0.5 seconds). In such a case, fi rst let the battery cool,
then start charging.
○ When the pilot lamp fl ickers in red (at 0.2-seconds
intervals), check for and take out any foreign objects in
the charger's battery connector. If there are no foreign
objects, it is probable that the battery or charger is
malfunctioning. Take it to your authorized Service
Center.
○ Since the built-in micro computer takes about 3 seconds
to confi rm that the battery being charged with chargers
are taken out, wait for a minimum of 3 seconds before
reinserting it to continue charging. If the battery is
reinserted within 3 seconds, the battery may not be
properly charged.

SELECT OPERATION MODE
Pressing the changeover switch allows the selection of
rotation speed and the auto stop function.
○ Rotation speed (Low mode/Normal mode) (Fig. 12)
○ Auto stop mode (on/off ) (Fig. 13)
AUTO STOP FUNCTION
In selection mode, pressing the button for longer than two
seconds will move to memory mode. (Fig. 13)
(At the same time the auto stop lamp will blink.)
Conduct drilling when the auto stop lamp is fl ashing. The
time between switching ON and switching OFF is stored by
the tool.
(At the same time, the auto stop lamp will light up.)
Conduct drilling when the auto stop lamp is fl ashing.
Continuous drilling is possible as the memory storage time
will be recorded by the tool until the auto stop function's auto
stop mode is cancelled.
The auto stop function is cancelled by pressing the
changeover switch once again for over two seconds.
(At the same time, the auto stop lamp will switch off .)
CAUTION
○ Switch ON the tool once you place the tip of the tool on

This product is equipped with an auto stop function to
support continuous drilling work. The function features a
memory mode for storing the work time for drilling from
