○
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 / UC18YRSL / UC18YFSL 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 driver bit (WH14DBDL / WH18DBDL)
Using a broken bit or one with a worn out tip is dangerous
because the bit can slip. Replace it.
2. Inspecting the socket (WR14DBDL / WR18DBDL)
A worn or deformed hex. or a square-holed socket will
not give an adequate tightness to the
fi
tting between
the nut or anvil, consequently resulting in loss of
tightening torque. Pay attention to wear of a socket holes
periodically, and replace with a new one if needed.
3. 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.
4. Maintenance of the motor
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.
5. Cleaning on the outside
When the tool 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.
6. Storage
Store the tool in a place in which the temperature is less
than 40°C, and out of reach of children.
NOTE
Make sure that the battery is fully charged when stored
for a long period (3 months or more). The battery with
smaller capacity may not be able to be charged when
used, if stored for a long period.
NOTE
Storing lithium-ion batteries.
Make sure the lithium-ion batteries have been fully
charged before storing them.
Prolonged storage of batteries with a low charge
may result in performance deterioration, signi
fi
cantly
reducing battery usage time or rendering the batteries
incapable of holding a charge.
However,
signi
fi
cantly reduced battery usage time may
be recovered by repeatedly charging and using the
batteries two to
fi
ve times.
If the battery usage time is extremely short despite
repeated charging and use, consider the batteries dead
and purchase new batteries.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
Important notice on the batteries for the Hitachi
cordless power tools
Please always use one of our designated genuine
batteries. We cannot guarantee the safety and
performance of our cordless power tool when used with
batteries other than these designated by us, or when
the battery is disassembled and modi
fi
ed (such as
disassembly and replacement of cells or other internal
parts).
GUARANTEE
We guarantee Hitachi Power Tools in accordance with
statutory/country speci
fi
c regulation. This guarantee does
not cover defects or damage due to misuse, abuse, or
normal wear and tear. In case of complaint, please send
the Power Tool, undismantled, with the GUARANTEE
CERTIFICATE found at the end of this Handling instruction,
to a Hitachi Authorized Service Center.
