SERVICE CENTER.
5. Disconnect battery charger from the power plug.
CAUTION
Do not pull the plug out of the receptacle by
pulling on the cord.
Make sure to grasp adapter plug when removing
from receptacle to avoid damaging adapter.
6. Remove the battery from the battery charger.
Supporting the charger base with hand, pull out
the battery from the charger base.
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 battery perform longer
1. Do not recharge the batteries after they become
completely exhausted.
When you find the power pilot lamp change from
green to red on ther nailer handle, should stop to
operate the nailer and recharge its battery. If you
continue to use the nailer 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 continuously
used, the battery charger will be heated, thus
constituting 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 may not light. The battery will not be
recharged. In such a case, let the battery cool
before charging.
■ If the battery charger does not work while the
battery is mounted correctly, it is probable that
the battery or charger is malfunctioning. Take
it to your *)6 authorized Service Center.
