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
䡬 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.
䡬 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.
11
English
CAUTION:
● If the battery is rechraged when it is warm due to battery use or exposure to sunlight,
the pilot lamp may light in green.
The battery will not be recharged. In such a case, let the battery cool before charging.
● When the pilot lamp flickers 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.
DC POWER SOURCE METHOD
A cordless tool can be used with a 120V power source by using an adapter with the charger.
1. Connecting the adapter (ET18-18A)
(1) Inserting/unplugging the adapter plug
WARNING: ALWAYS confirm the switch is off, to prevent accidents.
1 Inserting
Confirm that the lock lever on the adapter plug socket
on the charger is in the 1 FREE position. With the
arrow “ ” on the adapter plug facing upward, insert
the plug firmly into the socket. Turn the lock lever

3. DC Power Source Lamp
(1) Normal Use
When the adapter is connected and “power source ready” red lamp is continuously
lit, the cordless tool can be used by triggering the switch.
(2) Output may stop in the following conditions.
1 High temperature protection
Work involving large continuous current and intense continuous work in high
temperature locations will raise the internal temperature of the charger. To prevent
breakdowns caused by high temperatures, stop the output, and the red lamp will
flicker (0.2 second cycle) repeatedly. Rest the charger for at least 30 minutes.
Then, unplug the charger from the outlet, wait 20 seconds, and plug it in again. (This
resets the output function, and restores output voltage.)
2 Continuous overuse protection
When a cordless tool is used continuously for a long time without breaks (such as
work which would consume three Hitachi 2Ah batteries in one hour), stop the output,
and the red lamp will flicker (0.2 second cycle) repeatedly. Rest the cordless tool for
at least 30 minutes.
Then, unplug the charger from the outlet, wait 20 seconds, and plug it in again. (This
resets the output function, and restores output voltage.)
13
English
CAUTION: ALWAYS rest the cordless tool at least 30 minutes before resetting the
output function.
3 Excessive current protection
When continuous excessive current is detected, to prevent cordless tool or charger
breakdowns caused by sudden overheating, stop the output, and the red lamp will
flicker repeatedly.
Rest the cordless tool and the charger for at least 30 minutes.
Then, unplug the charger from the outlet, wait 20 seconds, and plug it in again. (This
resets the output function, and restores output voltage.)
