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

〈UC18YG〉
Before using the cordless jig saw, charge the battery as
follows.
Insert the battery firmly, until it contacts the bottom of
the charger compartment.
If the battery is inserted in the reverse direction, not
only recharging will become impossible, but it may
also cause problems in the charger such as deformed
recharging terminal.
When inserting a battery in the charger, charging will
commence and 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).
The indications of the pilot lamp will be as shown in
Table 1, according to the condition of the charger or
the rechargeable battery.
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. In
such a case, first let the battery cool, then start
charging.
When the pilot lamp flikers 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
UC18YRL 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.
Malfunction in the battery
or the charger.
Battery overheated.
Unable to charge
(Charging will commence
when battery cools).
