CAUTION:
Never short-circuit the battery.
2. Battery installation
Insert the battery while observing its polarities (see
Fig. 2).
CHARGING
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.
Firmly insert the battery into the charger till it contacts
the bottom of the charger and checking the polarities
as shown in Fig. 3.

NOTE: When standby for cooling battery, UC18YRL cools the overheated battery by cooling fan.
(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.

(3) Regarding recharging time
Depending on the combination of the charger and
batteries, the charging time will become as shown in
Table 3.

Approx. 45 min.
CAUTION:
If the batteries are inserted in the reverse direction,
not only recharging will become impossible, but it
may also cause problems in the charger such as a
deformed recharging terminal.
3. Charging
When inserting a battery in the charger, charging will
commence and the pilot lamp will light 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.

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 low 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.
