I. GENERAL SAFETY 
RULES FOR ALL 
BATTERY OPERATED 
TOOLS
SAVE THESE INSTRUCTIONS
Work Area
1)Keep your work area clean and well
lit.
Cluttered benches and dark areas invite
accidents.
2)Do not operate power tools in explo-
sive atmospheres, such as in the
presence of flammable liquids,
gases, or dust. 
Power tools create sparks which may
ignite the dust or fumes.
3)Keep bystanders, children, and visi-
tors away while operating a power
tool. 
Distractions can cause you to lose con-
trol. Make sure that no one is beneath,
or on the other side of the area when
you are working.
Electrical Safety
4)A battery operated tool with integral
batteries or a separate battery pack
must be recharged only with the
specified charger for the battery. 
A charger that may be suitable for one
type of battery may create a risk of fire
when used with another battery.
5)Use battery operated tool only with
specifically designated battery pack. 
Use of any other batteries may create a
risk of fire.
Personal Safety
6)Stay alert, watch what you are doing,
and use common sense when operat-ing a power tool. Do not use tool
while tired or under the influence of
drugs, alcohol, or medication.
A moment of inattention while operating
power tools may result in serious per-
sonal injury.
7)Dress properly. Do not wear loose
clothing or jewelry. Contain long hair.
Keep your hair, clothing, and gloves
away from moving parts.
Loose clothes, jewelry, or long hair can
be caught in moving parts.
8)Avoid accidental starting. Be sure
switch is in the locked or off position
before inserting battery pack. 
Carrying tools with your finger on the
switch or inserting the battery pack into
a tool with the switch on invites acci-
dents.
9)Remove adjusting keys or wrenches
before turning the tool on. 
A wrench or a key that is left attached to
a rotating part of the tool may result in
personal injury.
10)Do not overreach. Keep proper foot-
ing and balance at all times. 
Proper footing and balance enable bet-
ter control of the tool in unexpected situ-
ations.
11 )Use safety equipment. Always wear
eye protection. 
Dust mask, non-skid safety shoes, hard
hat, or hearing protection must be used
for appropriate conditions.
Tool use and care
12)Use clamps or other practical way to
secure and support the workpiece to
a stable platform. 
Holding the work by hand or against
your body is unstable and may lead to
loss of control.
13)Do not force tool. Use the correct tool
for your application. 
The correct tool will do the job better
and safer at the rate for which it is
designed.
14)Do not use tool if switch does not
turn it on or off. 
WARNING! 
READ AND UNDERSTAND ALL INSTRUCTIONS.
• Failure to follow all instructions listed
below, may result in electric shock, fire
and/or serious personal injury. 
						

							—   3   —
A tool that cannot be controlled with the
switch is dangerous and must be
repaired.
15)Disconnect battery pack from tool or
place the switch in the locked or off
position before making any adjust-
ments, changing accessories, or
storing the tool. 
Such preventive safety measures
reduce the risk of starting the tool acci-
dentally.
16)Store idle tools out of reach of chil-
dren and other untrained persons. 
Tools are dangerous in the hands of
untrained users.
17)When battery pack is not in use, keep
it away from other metal objects like:
paper clips, coins, keys, nails,
screws, or other small metal objects
that can make a connection from one
terminal to another. 
Shorting the battery terminals together
may cause sparks, burns or a fire.
18)Maintain tools with care. Keep cutting
tools sharp and clean. 
Properly maintained tools with sharp
cutting edge are less likely to bind and
are easier to control.
19)Check for misalignment or binding of
moving parts, breakage of parts, and
any other condition that may affect
the tool’s operations. If damaged,
have the tool serviced before using. 
Many accidents are caused by poorly
maintained tools.
20)Use only accessories that are recom-
mended by the manufacturer for your
model.
Accessories that may be suitable for
one tool may create a risk of injury when
used on another tool.
Service
21)Tool service must be performed only
by qualified repair personnel.
Service or maintenance performed by
unqualified personnel may result in a
risk of injury.22)When servicing a tool, use only iden-
tical replacement parts. Follow
instructions in the Maintenance sec-
tion of this manual. 
Use of unauthorized parts or failure to
follow Maintenance Instructions may
create a risk of shock or injury.
II. SPECIFIC SAFETY 
RULES
1)Hold tool by insulated gripping sur-
faces when performing an operation
where the cutting tool may contact
hidden wiring.
Contact with a “live” wire will also make
exposed metal parts of the tool “live”
and shock the operator.

WARNING: 
Some dust created by power sanding,
sawing, grinding, drilling, and other con-
struction activities contains chemicals
known to the State of California to cause
cancer, birth defects or other reproduc-
tive harm. Some examples of these
chemicals are:
• Lead from lead-based paints
• Crystalline silica from bricks and
cement and other masonry products
• Arsenic and chromium from chemically-
treated lumber.
To reduce your exposure to these chemi-
cals:
work in a well ventilated area, and work
with approved safety equipment, such as
dust masks that are specially designed
to filter our microscopic particles.

Clutch Torque Setting
Adjust the torque to one of the 18 possible set-
tings or “ ” position to the job.
CAUTION:Test the setting before actual opera-
tion. Set the scale at this mark ( ).
Note:When the brake operates, a braking sound
may be heard. This sound indicates
engagement of the bit lock.
CAUTION:To eliminate excessive temperature
increase of the tool surface, do not
operate the tool continuously using
two or more battery packs.
Tool needs cool off time before
switching to another pack.
•Do not close up vent holes on
body sides of the body during
operation.  Otherwise, the machine
function is adversely affected to
cause a failure.
•Do not strain the tool (motor).
This may cause damage to the
unit.
•Use the machine in such a way as
to prevent the air from the body
vent holes from blowing directly
onto your skin.  Otherwise, you
may get burnt.
•When operating with a Ni-MH bat-
tery pack, make sure the place is
well-ventilated.
For Appropriate use of Battery pack
Ni-MH Battery pack 
(EY9200/EY9201/EY9230/EY9231)
• Charge the Ni-MH battery fully before storage
in order to ensure a longer service life.
• The ambient temperature range is between
0°C and 40°C.
If the battery pack is used when the battery
temperature is below 0°C, the tool may fail to
function properly.  In that case, charge the bat-
tery until charging is completed for appropriate
functioning of the battery.
Ni-Cd Battery pack 
(EY9106/EY9136)
• Nickel cadmium battery pack requires a
“BREAK-IN PERIOD” to reach maximum oper-
ating capacity. The “BREAK-IN PERIOD” is
accomplished during normal usage during the
first 6-8 charge and discharge cycles of the
battery pack.
After the “BREAK-IN PERIOD” is completed,
the battery pack will maintain maximum operat-
ing capacity throughout the normal life of the
battery pack.
Battery Pack LifeThe rechargeable batteries have a limited life. If
the operation time becomes extremely short after
recharging, replace the battery pack with a new
one.
Charging
Note:When you charge the battery pack for the
first time, or after prolonged storage,
charge it for about 24 hours to bring the
battery up to full capacity.
EY0230
1. Plug the charger into the AC outlet.
Note:Sparks may be produced when the plug is
inserted into the AC power supply, but this
is not a problem in terms of safety.
2. Insert the battery pack firmly into the charger.
3. During charging, the charging lamp will be lit.
When charging is completed, an internal elec-
tronic switch will automatically be triggered to
prevent overcharging.
• Charging will not start if the battery pack is
warm (for example, immediately after
heavy-duty operation).
The orange standby lamp will be lit until the
battery cools down. Charging will then
begin automatically.
4. When charging is completed, the charging
lamp will start flashing rapidly.

5. When in any of the conditions that battery
pack is too cool, or the battery pack has not
been used for a long time, the charging lamp
starts flashing slowly to indicate protective
charging. Protective charging takes longer to
fully charge the battery pack, than the stan-
dard charging time. (Max. charging time is
approx. 90 minutes).
• If a fully charged battery pack is inserted
into the charger again, the charging lamp
may light up and then flash slowly. After
several minutes, the charging lamp may
flash quickly to indicate the charging is
completed. 
6. If the charging lamp does not light immedi-
ately after the charger is plugged in, or if after
the standard charging time the lamp does not
go off, consult an authorized dealer.Note: •When charging a cool battery pack
(below 5°C) in a warm place, leave the
battery pack at the place and wait for
more than one hour to warm up the bat-
tery to the level of the ambient tempera-
ture. (Battery pack may not be fully
charged.)
•Cool down the charger when charging
more than two battery packs consecu-
tively.
•Do not insert your fingers into contact
hole, when holding charger or any other
occasions.
CAUTION: •Do not use power source from an
engine generator.
•Do not cover vent holes on the
charger and the battery pack.
