Indications of the lamp
Regarding the temperature of the rechargeable
battery.
The temperatures for rechargeable batteries are
as shown in the table below, and batteries that
have become hot should be cooled for a while
before being recharged.
4. Disconnect battery charger from the receptacle.
CAUTION:
Do not pull the plug out of the receptacle by pulling
on the cord.
Make sure to grasp the plug when removing from
receptacle to avoid damaging cord.
5. Remove the battery from the battery charger.
Supporting the battery charger with hand, pull out
the battery from the battery charger.
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 up
green. In such a case, first let the battery cool, then
start charging.
When the pilot lamp flikers in red (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.
Since the built-in micro computer takes about 3
seconds to confirm that the battery being charged
with the charger 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.
How to make the batteries perform longer.
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.
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.
BEFORE USE
Check the work area to make sure that it is clear of debris
and clutter.
Clear the area of unnecessary personnel. Ensure that
lighting and ventilation is adequate.
