NOTE
The recharging time may vary according to the ambient
temperature and power source voltage.
<UC18YML2>
Especially, using a DC 12 V in-car power source may
require longer recharging time at high temperatures.
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.
4. Disconnect the charger’s power cord from the
receptacle or cigarette lighter socket.
5. 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 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 or lights
for 1 second, does not light for 0.5 seconds (o
ff
for
0.5 seconds). In such a case,
fi
rst let the battery cool,
then start charging.
○
When the pilot lamp
fl
ickers 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 con
fi
rm that the battery being charged with
charger 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
fl
ickers in green (every 0.2 seconds)
continuously. (UC18YML2)
If the voltage is 12 V 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.

CAUTION
Select mode while the trigger switch is released. Failure
to do so could result in malfunction.
Once you install the battery and switch on the power, you
can change modes with each press of the mode selector
switch.
●
Speed change mode allows the number of maximum
strokes to be switched between 3 levels: low speed,
medium speed and high speed.
With speed change mode, the set number of maximum
strokes will be maintained even if there is a change in
load.
