CHARGING
〈
UC18YRL
〉
Before using the power tool, charge the battery as follows.
1. Connect the charger’s power cord to a receptacle
When the power cord is connected, the charger’s
pilot lamp will blink in red (At 1-second intervals).
2. Insert the battery into the charger
Insert the battery firmly, until it contacts the bottom of
the charger compartment. (See
Fig. 3
)
CAUTION
䡬
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.
(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
.

Charging time (At 20°C)
3. Charging
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
).
(1) Pilot lamp indication
The indications of the pilot lamp will be as shown in

Table 1
Indications of the lamps
NOTE:
When standby for cooling battery, UC18YRL cools the overheated battery by cooling fan.
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
Be sure to pull out the battery from the charger after
use, and then keep it.
CAUTION
䡬
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.
䡬
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.
䡬
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.
