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.
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 (off 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 confi 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 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 tool
2. Inspecting the mounting screws
3. Maintenance of the motor
4. Inspecting the carbon brushes (Fig. 12)

Action
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.
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.
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.
The motor employs carbon brushes which are
consumable parts. Since and excessively worn carbon
brush can result in motor trouble, replace the carbon
