REMOVAL AND INSTALLATION
METHOD OF BATTERY
⅜ How to install the battery
Align the battery with the groove in tool handle and
slip it into place.
Always insert it all the way until it locks in place with a
little click. If not, it may accidentally fall out of the tool,
causing injury to you or someone around you.
⅜ How to remove the battery
Withdraw battery from the tool handle while pressing
the latch on the side of the battery.
CHARGING METHOD
NOTE: Before plugging into the receptacle, make sure the
following points.
⅜ The power source voltage is stated on the
nameplate.
⅜ The cord is not damaged.
WARNING
ⅷ Do not charge at voltage higher than indicated on
the name plate.
If charged at voltage higher than indicated on the
nameplate, the charger will burn up.
ⅷ Do not use the electrical
cord if damaged. Have it
repaired immediately.
1. Insert the battery into the battery charger. Make sure it
contacts the bottom of the battery charger.
2. Insert the plug of battery charger into the receptacle.
3. Charging
⅜ When the plug of battery charger has been inserted
into the receptacle, charging will commence and the
pilot lamp will light on.
NOTE: If the pilot lamp does not light, pull out the plug
from the receptacle and check if the battery is
properly mounted.
⅜ In approx. 60 min. at 70°F (20°C), when the battery is
fully charged, the pilot lamp will go out.
NOTE: The battery charging time becomes longer when
a temperature is low or the voltage of the power
source is too low.
When the pilot lamp does not go off even if more
than four hour has passed after start of the
charging, stop the charging and contact your
HITACHI AUTHORIZED SERVICE CENTER.
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.
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.
⅜ 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.
⅜ 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
ⅷ When the battery charger has been continuosly
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.
