Maintenance And Inspection - Hitachi WH 18DBDL Bedienungsanleitung

○ 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
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
5. Cleaning on the outside
6. Storage

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.
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.
Store the tool in a place in which the temperature is less
than 40°C, and out of reach of children.
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.
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, signifi cantly
reducing battery usage time or rendering the batteries
incapable of holding a charge.
However, signifi 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.
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
