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.
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
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 confi rm that the battery being charged
with UC18YMRL 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.
4. Fuse replacement of cigarette lighter connecting
plug
CAUTION
For continued protection
replaceonly with same type and ratings of fuse in
cigarette lighter connecting plug.
250V, 6A, DC
5. Service parts list
CAUTION

tool to the Hitachi Authorized Service Center when
requesting repair or other maintenance.
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
