1. Battery removal
Hold the handle tightly and push the battery latch to
remove the battery (see Figs. 1 and 2).
CAUTION
Never short-circuit the battery.
2. Battery installation
Insert the battery while observing its polarities (see
Fig. 2).

2. Insert the battery into the charger
Firmly insert the battery into the charger till it contacts the
bottom of the charger as shown in Fig. 3.
3. Charging
When inserting a battery in the charger, the pilot lamp will
light up continuously in red.
When the battery becomes fully recharged, the pilot lamp
will blink in red (At 1-second intervals). (See Table 1)
(1) Pilot lamp indication
The indications of the pilot lamp will be as shown in
Table 1, according to the condition of the charger or the
rechargeable battery.
Table 1
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 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.
Battery overheated.
Unable to charge
(Charging will commence
when battery cools).
Malfunction in the battery or
the charger.
