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 charge indicator lamp of the charger lights
for 0.3 seconds, does not light for 0.3 seconds (off for
0.3 seconds). In such a case, fi rst let the battery cool,
then start charging.
○ When the charge indicator lamp fl ickers (at 0.2-second
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
UC18YSL3 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.

NOTE
To prevent the battery power consumption caused
by forgetting to turn off the LED light, the light goes off
automatically in about 2 minutes.
*2 Tightening mode selector function
CAUTION
Select tightening mode while the trigger switch is
released. Failure to do so could result in malfunction.
By using the Tightening mode selector switch on the side
of the tool body, the tightening torque can be adjusted
according to the type of work.
The Tightening mode switches between 4 diff erent modes
each time the Tightening mode selector switch is pressed.
Normal mode allows screws to be tightened smoothly and
gently.
Under normal circumstances, use Normal mode.

Power mode is suitable for heavy-load work that requires
more force, such as tightening long screws.
Use it when you feel that Normal mode lacks suffi cient
power.
Self-drilling screw mode is used for tightening self-
drilling Teks screws. This mode reduces the chances of
overtightening that could result in severing of the screw
head, breakage of the screw, or slippage.
NOTE
○ The appropriate mode diff ers depending on the screw
and the material being screwed. Drive in a few test
screws and adjust the mode setting accordingly.
○ The tightening mode selector switch can only be set after
the battery has been installed in the driver and the trigger
switch has been pulled once.

MAINTENANCE AND INSPECTION

1. Inspecting the driver bit
Using a broken bit or one with a worn out tip is dangerous
because the bit can slip. Replace it.
2. 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.
3. 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.
4. Inspection of terminals (tool and battery)
Check to make sure that swarf and dust have not
collected on the terminals.
On occasion check prior, during and after operation.
CAUTION
Remove any swarf or dust which may have collected on
the terminals.
Failure to do so may result in malfunction.
5. Cleaning on the outside
When the power 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 power tool in a place in which the temperature
is less than 40°C and out of reach of children.
NOTE
Storing lithium-ion batteries.
Make sure the lithium-ion batteries have been fully
charged before storing them.
Prolonged storage (3 months or more) 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.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
