(2)Regarding the temperature 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

Temperatures at

Rechargeable batteries which the battery can be recharged

BSL1415, BSL1815,

(2)Avoid recharging at high temperatures.

A rechargeable battery will be hot immediately after use. If such a battery is recharged immediately after use, its internal chemical substance will deteriorate, and the battery life will be shortened. Leave the battery and recharge it after it has cooled for a while.

CAUTION

￿ 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 for 1 second,

does not light for 0.5 seconds (off for 0.5 seconds). In

such a case, first let the battery cool, then start

￿ When the pilot lamp flickers (at 0.2-second intervals),

check for and take out any foreign objects in the

4.Disconnect the charger’s power cord from the receptacle

5.Hold the charger firmly and pull out the battery

NOTE

After charging, 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.

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 UC18YGSL 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.

1.Connect the charger’s power cord to the receptacle. When connecting the plug of the charger to a receptacle, the 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.

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, 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 4)

(1)Pilot lamp indication

The indications of the pilot lamp will be as shown in Table 4, according to the condition of the charger or the rechargeable battery.
