.

CHARGING

Before using the driver drill, charge the battery as follows

.

1

. 

Connect

the

charger

power

cord

to

the

receptacle

Connecting the power cord will turn on the charger

.

2

. 

Insert

the

battery

into

the

charger

  Insert the battery 

fi

 rmly while observing its direction, 

until it contacts the bottom of the charger (See 

Fig

. 

3,

4

)

.

 (The pilot lamp on the UC18YK or the battery 

set lamp on the UC9SF or UC12SF lights up

.

)

CAUTION

  If the pilot lamp on the UC18YK or the battery set 

lamp on the UC9SF or UC12SF does not light up 

when the battery is inserted, pull out the power cord 

from the receptacle and check the battery mounting 

condition

.

(1)  Regarding the temperatures of the rechargeable battery

  The temperatures for rechargeable batteries are as 

shown in 

Table

(2)  Regarding recharging time

  Depending on the combination of the charger and 

batteries, the charging time will become as shown in 

Table

(Less than

UC18YK:

The pilot lamp goes o

ff

  to indicate that the battery is fully 

charged

.

  The battery charging time becomes longer when a 

temperature is low or the voltage of the power source is 

too low

.

UC9SF

or

UC12SF:

  Using the above times as a guide, remove the battery 

from the charger

.

The battery set lamp goes o

ff

  when the battery is removed 

from the charger

.

When the temperature of the battery is low (less than 0°C) 

or the voltage of the power source is low, the capacity 

of the battery after charging for 180 minutes is reduced

.

If the battery performance seems poor during practical 

use, charge for 4 to 6 hours

.

CAUTION

  If the battery is heated due to direct sunlight, etc

.

, 

just after operation, the charger pilot lamp may not 

light up

.

 At that time, cool the battery 

fi

 rst, then start 

charging

.

3

. 

Disconnect

the

charger’s

power

cord

from

the

receptacle

4

. 

Hold

the

charger

 fi 

rmly

and

pull

out

the

battery

NOTE

  After charging, pull out batteries from the charger 

fi

 rst, 

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 

fi

 rst 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
