turn it on or off.
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.
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
adjustments, changing accessories,
or storing the tool.
22)When servicing a tool, use only
identical replacement parts. Follow
instructions in the Maintenance
section of this manual.
Such preventive safety measures
reduce the risk of starting the tool
accidentally.
Use of unauthorized parts or failure
to follow Maintenance Instructions
may create a risk of shock or injury.
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.
.
SPECIFIC SAFETY
RULES
1) Hold tool by insulated gripping sur-
faces when performing an opera-
tion 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.
Shorting the battery terminals togeth-
er may cause sparks, burns or a fire.
18)Maintain tools with care. Keep cut-
ting tools sharp and clean.
2) Wear ear protectors when using the
tool for extended periods.
Properly maintained tools with sharp
cutting edge are less likely to bind
and are easier to control.
Prolonged exposure to high intensity
noise can cause hearing loss.
3) Be aware that this tool is always in
an operating condition, it does not
have to be plugged into an electrical
outlet.
4) Do not operate the Forward/
Reverse lever when the Variable
speed control trigger is on.
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 rec-
ommended by the manufacturer for
your model.
The battery will discharge rapidly and
damage to the unit may occur.
5) If the bit becomes jammed, imme-
diately turn the Variable speed con-
trol trigger off to prevent an over-
load which can damage the battery
pack or motor. Use reverse motion
to loosen jammed bits.
Accessories that may be suitable for
one tool may create a risk of injury
when used on another tool.
6) When storing or carrying the tool,
set the Forward/Reverse lever to
the center (switch lock) position.
7) Do not strain the tool by holding
the speed control trigger halfway
(speed control mode) so that the
motor stops.

other construction activities con-
tains chemicals known to the State
of California to cause cancer, birth
defects or other reproductive harm.
Some examples of these chemicals
are:
4) Do not expose charger to rain or snow.
5) To reduce risk of damaging the electric
plug and cord, pull by plug rather than
cord when disconnecting charger.
6) Make sure cord is located so that it
will not be stepped on, tripped over,
or otherwise subjected to damage or
stress.
Lead from lead-based paints
Crystalline silica from bricks and
cement and other masonry prod-
ucts
Arsenic and chromium from chemi-
cally-treated lumber.
To reduce your exposure to these
chemicals: work in a well ventilated
area, and work with approved safe-
ty equipment, such as dust masks
that are specially designed to filter
out microscopic particles.
7) An extension cord should not be used
unless absolutely necessary.
Use of improper extension cord could
result in a risk of fire and electric
shock. If extension cord must be
used, make sure that:
a.pins on plug of extension cord are
the same number, size and shape
as those of plug on charger.
b. extension cord is properly wired
and in good electrical condition.
c.
wire size is large enough for
ampere rating of charger as speci-
fied below.

terms of safety.
2. Insert the battery pack firmly into the
charger.
For Appropriate use of
Battery pack
Battry pack
Ni-MH Battery pack (EY9251)
To AC
outlet
Charge the Ni-MH battery fully before
storage in order to ensure a longer ser-
vice life.
The ambient temperature range is be-
tween 0°C (32°F) and 40°C (104°F).
If the battery pack is used when the bat-
tery temperature is below 0°C (32°F), the
tool may fail to function properly. In that
case, charge the battery until charging is
completed for appropriate functioning of
the battery.
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 con-
nection from one terminal to another.
Shorting the battery terminals together
may cause sparks, burns or a fire.
Battery
charger
3. During charging, the charging lamp will
be lit.
When charging is completed, an inter-
nal electronic switch will automatically
be triggered to prevent overcharging.
Charging will not start if the battery
pack is warm (for example, immedi-
ately after heavy-duty operation).
The orange standby lamp will be lit
until the battery cools down. Charging
will then begin automatically.
When operating with a Ni-MH bat-
tery pack, make sure the place is well-
ventilated.
4. When charging is completed, the
charging lamp will start flashing quickly
in green color.
5. When in any of the conditions that
battery pack is too cool, or the bat-
tery pack has not been used for a
long time, the charging lamp is lit. In
this case, charging takes longer to
fully charge the battery pack, than the
standard charging time.
Battery Pack Life
The rechargeable batteries have a lim-
ited life. If the operation time becomes
extremely short after recharging,
replace the battery pack with a new one.
NOTE:
Use under extremely hot or cold
conditions will reduce operating
capacity per charge.
If a fully charged battery pack is insert-
ed into the charger again, the charging
lamp light up. After several minutes,
the charging lamp may flash quickly to
indicate the charging is completed.
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.
