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.
CAUTION
When the battery charger has been continuously used,
the battery charger will be heated, thus constituting
the cause of the failures. Once the charging has been
completed, give 15 minutes rest until the next charging.
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
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 HiKOKI Authorized
Service Center.

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.
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 with new ones when it becomes worn to or near
the "wear limit" ⓐ. In addition, always keep carbon
brushes clean and ensure that they slide freely whithin
the brush holders.
When replacing the carbon brush with a new one, be
sure to use the HiKOKI Carbon Brush Code No. 999100.
Take out the carbon brush by fi rst removing the brush
cap and then hooking the protrusion of the carbon brush
with a fl at head screw driver, etc.
When installing the carbon brush, choose the direction
so that the nail ⓑ of the carbon brush agrees with the
contact portion ⓒ outside the brush tube. Then push it in
with a fi nger. Lastly, install the brush cap.
Be absolutely sure to insert the nail of the carbon brush
into the contact portion outside the brush tube. (You can
insert whichever one of the two nails provided).
Caution must be exercised since any error in this
operation can result in the deformed nail of the carbon
brush and may cause motor trouble at an early stage.
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 power 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.
