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

(3) Regarding recharging time
Depending on the type of battery, 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 short 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 been cooled for
a while.
CAUTION
If the battery has been heated right after operation
(or due to sunlight, etc.), the charger's pilot lamp
may not light in red. In such a case, first let the
battery cool, then start charging.
When the pilot lamp flickers in red quickly (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.
Since the built-in micro computer takes about 3
seconds to confirm that the battery being charged
with UC24YFB is 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.

PRIOR TO OPERATION

1. Mounting the blade
This unit employs a detachable mechanism that
enables mounting and removal of saw blades
without the use of a wrench or other tools.
Malfunction in the battery
or the charger
The battery temperature
is high, making recharging
impossible.
