CHARGING
Before using the power tool, charge the battery as follows.
1. Connect the charger's power cord to the receptacle.
2. Insert the battery into the charger. (Fig. 2)
Firmly insert the battery into the charger till it contacts the
bottom of the charger and checking the polarities.
Inserting the battery will turn on the charger (the pilot
lamp lights up).
CAUTION
○ If the pilot lamp does not light up, pull out the power
cord from the receptacle and check the battery
mounting condition.
○ If the battery is heated due to direct sunlight, etc.,
just after operation, the charger pilot lamp may not
light up. At that time, cool the battery fi rst, then start
charging.
● Regarding the temperatures and charging time of the
battery.
The temperatures and charging time will become as

NOTE
The recharging time may vary according to the ambient
temperature and power source voltage.
3. Disconnect the charger's power cord from the
receptacle.
4. Hold the charger fi rmly and pull out the battery.
NOTE
Be sure to pull out the battery from the charger after use,
and then keep it.
CAUTION
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 authorized
Service Center.

MAINTENANCE AND INSPECTION

1. Inspecting the tool
Since use of as dull tool will degrade effi ciency and
cause possible motor malfunction, sharpen or replace
the tool as soon as abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws be
loose, retighten them immediately. Failure to do so could
result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very "heart" of the power
tool. Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
4. Cleaning on the outside
When the driver drill is stained, wipe with a soft dry cloth
or a cloth moistened with soapy water. Do not use chloric
solvents, gasoline or paint thinner, for they melt plastics.
5. Storage
Store the driver drill in a place in which the temperature
is less than 40°C and out of reach of children.
NOTE
Storing lithium-ion batteries.
Make sure the lithium-ion batteries have been fully
charged before storing them.
Prolonged storage (3 month or more) of batteries with
a low charge may result in performance deterioration,
signifi cantly reducing battery usage time or rendering
the batteries incapable of holding a charge.
However, signifi cantly reduced battery usage time may
be recovered by repeatedly charging and using the
batteries two to fi ve times.
If the battery usage time is extremely short despite
repeated charging and use, consider the batteries dead
and purchase new batteries.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
Important notice on the batteries for the Hitachi
cordless power tools
Please always use one of our designated genuine
batteries. We cannot guarantee the safety and
performance of our cordless power tool when used with
batteries other than these designated by us, or when
the battery is disassembled and modifi ed (such as
disassembly and replacement of cells or other internal
parts).
