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.

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, according to the condition of the charger or

the rechargeable battery.

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.
