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) Lamp indication
The indications of the lamp will be as shown in
Table 1, according to the condition of the charger
or the rechargeable battery.
NOTE
After charging, pull out batteries from the charger
first, and then keep the batteries properly.
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.
(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
When the battery charger has been continuosly
used, the battery charger will be heated, thus con-
stituting the cause of the failures. Once the charging
has been completed, give 15 minutes rest until the
next charging.
If the battery is recharged when it is warm due to
battery use or exposure to sunlight, the pilot lamp
blinks for 1 second, dose not light for 0.5 seconds
(off for 0.5 seconds).
The battery will not be recharged. In such a case,
let the battery cool before charging.
