(2) Regarding the temperature of the rechargeable
battery.
The temperatures for rechargeable batteries are as
shown in the table below, and batteries that have
become hot should be cooled for a while before being
recharged.

Temperatures at which the battery can be recharged
0°C - 50°C
(3) Regarding recharging time

shows the recharging time required according
to the type of battery.

NOTE
The recharging time may vary according to the
ambient temperature.
Especially, using a DC 12V in-car power source may
require longer recharging time at high temperatures.
E.g., approx. 170-180 min (3.0 Ah) at 40°C

NOTE

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
fi
rst 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.
(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,
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 UC18YML2 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.
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.
MAINTENANCE
AND
INSPECTION
1.
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.
2.
Cleaning
of
the
charger
When the charger 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.
3.
Store
idle
charger
When not in use, the charger should be stored in dry,
high or locked-up place — out of reach of children.
