(3) Regarding recharging time
Depending on the combination of the charger and
batteries, the charging time will become as shown in
Table 3.

NOTE
The recharging time may vary according to the
ambient temperature and power source voltage.
<UC18YML2>
Especially, using a DC 12V in-car power source may
require longer recharging time at high temperatures.
CAUTION
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.
4. Disconnect the charger's power cord from the
receptacle or cigarette lighter socket
5. Hold the charger firmly and pull out the battery
NOTE
Be sure to pull out the battery from the charger after
use, and then keep it.
How to make the batteries perform longer
(1) 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.
(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
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 flickers in red (at 0.2-seconds
intervals), check for and take out any foreign objects
in the charger's battery connector. 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 UC18YML2 / UC18YRSL / UC18YFSL / UC18YGSL
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.
Check the voltage of the in-car power source when
the pilot lamp flickers in green (every 0.2 seconds)
continuously. (UC18YML2)
If the voltage is 12V or lower, it indicates that the car
battery has weakened and cannot be charged.
If the pilot lamp does not blink in red (every second)
even though the charger cord or cigarette lighter
connecting plug is connected to the power, it indicates
that the protection circuit of the charger may be
activated.
Remove the cord or plug from the power and then
connect it again after 30 seconds or so. If this does
not cause the pilot lamp to blink in red (every second),
please take the charger to the Hitachi Authorized
Service Center.

PRIOR TO OPERATION

1. Preparing and checking the work environment
Make sure that the work site meets all the conditions
laid forth in the precautions.
2. Checking the battery
Make sure that the battery is installed firmly. If it is at
all loose it could come off and cause an accident.
3. Installing the bit
Always follow the following procedure to install driver
bit. (Fig. 5)
(1) Pull the guide sleeve away from front of the tool.
(2) Insert the bit into the hexagonal hole in the anvil.
(3) Release the guide sleeve and it returns to its original
position.
(4) If you want to remove the bit, pull the guide sleeve
away from front of the tool.
CAUTION
If the guide sleeve does not return to its original
position, then the bit is not installed properly.
HOW TO USE
1. Check the rotational direction
The bit rotates clockwise (viewed from the rear side)
by pushing the R-side of the push button.
The L-side of the push button is pushed to turn the bit
counterclockwise. (See Fig. 6) (The
are provided on the body.)
2. Switch operation
When the trigger switch is depressed, the tool rotates.
When the trigger is released, the tool stops.
The rotational speed of the drill can be controlled by
varying the amount that the trigger switch is pulled.
Speed is low when the trigger switch is pulled slightly
and increases as the trigger switch is pulled more.
NOTE
A buzzing noise is produced when the motor is about
to rotate. This is only a noise, not a machine failure.
3. Using the hook
The hook is used to hang up the power tool to your
waist belt while working.
