GENERAL POWER TOOL SAFETY
WARNINGS
WARNING
Read all safety warnings and all instructions.
Failure to follow the warnings and instructions may result in
electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-
operated (corded) power tool or battery-operated (cordless)
power tool.
1) Work area safety
a) Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust.

4. Disconnect the charger’s power cord from the
receptacle.
5. Hold the charger firmly and pull out the battery.
NOTE
Be sure to pull out the battery from the charger after use,
and then keep it.
Regarding electric discharge in case of new batteries,
etc.
As the internal chemical substance of new batteries and
batteries that have not been used for an extended period
is not activated, the electric discharge might be low when
using them the first and second time.This is a temporary
phenomenon, and normal time required for recharging
will be restored by recharging the batteries 2 – 3 times.
How to make the batteries perform longer.
(1) Recharge the batteries before they become completely
exhausted.
When you feel that the power of the tool becomes
weaker, stop using the tool and recharge its battery.
If you continue to use the tool and exhaust the electric
current, the battery may be damaged and its life will
become shorter.
(2) Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after
use. If such a battery is recharged immediately after
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 (offfor
0.3 seconds). In such a case, first let the battery cool,
then start charging.
○When the charge indicator lamp flickers (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 confirm 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.

ABOUT THE PROTECTION
FUNCTIONS
This product features functions that are designed to protect
the tool itself as well as the battery. While the switch is
pulled, if any of the safeguard functions are triggered
during operation, the display lamp will blink as described in
Table 3. When any of the safeguard functions are triggered,
immediately remove your finger from the switch and follow
the instructions described under corrective action.

REACTIVE FORCE CONTROL
This product is equipped with a Reactive Force Control
(RFC) feature that reduces jerking of the tool body.
If the tool bit is suddenly overburdened, any jerking of the
tool body is reduced by activation of the slip clutch or by
stopping of the motor by the sensor built into the tool body.
If the motor is stopped because of overburdening detection
by the controller, the RFC indicator lamp will blink while the
switch is pulled. In addition, the lamp will continue blinking
for approximately three seconds after the switch is released.
The motor will remain stopped while the lamp is blinking.
(Fig. 21)
Because the RFC feature may not activate or its performance
may be insufficient depending on the working environment
and conditions, be careful not to suddenly overburden the
tool bit while operating.
●Possible causes of sudden overburdening
1Tool bit biting into material
2Impact against nails, metal or other hard objects
3Tasks involving prying or any excess application of
pressure, etc.
Also, other causes include any combination of the
aforementioned.
●When the reactive force control (RFC) is triggered
When the RFC is triggered and the motor stops, turn
offthe tool’s switch and remove the cause of the
overburdening before continuing operation.

before maintenance and inspection.
1. Inspecting the tool
Since use of as dull tool will degrade efficiency and
cause possible motor malfunction, sharpen or replace
the tool as soon as abrasion is noted.
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. Cleaning of the battery installation compartment
After drilling concrete, if concrete dust has accumulated
on the terminals or the area where the battery slides
within the battery installation compartment, clean offthe
accumulated concrete dust with a dry cloth before using
the tool. (Fig. 17)
Also, after cleaning, ensure that the battery can be
installed and removed smoothly from the tool.

CAUTION
Using the tool when the battery is covered with concrete
dust may lead to accidents such as the battery falling
during use.
Furthermore, such use may cause a malfunction or
contact failure between the battery and the terminals.
7. Storage
Store the power tool in a place in which the temperature
is less than 40°C and out of reach of children.
NOTE
