Read and understand all Instructions.

* Failure to follow all instructions listed

below, may result in electric shock,
fire and/or serious personal injury.

SAVE THESE INSTRUCTIONS
Work Area

1) Keep your work area clean and

welt lit.

Cluttered benches and dark areas
invite accidents.

2) Do not operate power tools In
explosive 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

visitors away while operating a

power tool.

Distractions can cause you to lose

control. 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 eeparate battery paick
must be recharged only with the
specified chargsr for the battery.

A charger that may be sukabie 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 cre
ate a risk of fire.

Personal Safety

6) Stay alert, watch what you are

doing, and use common sense
when operatihg a power tool. Do

. not use tool while tired or under

the Influence of drugs, alcohol, or

medication.

A moment of inattention while operat

ing power toots may result in serious
personal injury.

7) Dress properly. Do not wear loose
clothing or jewelry. Contain long
hair.

Keep your hair, clothing, and

gloves away from ntoving parts.

Loose clothes, jewelry, or long hair

can be caught in moving parts.

B) Avoid accidental starting. Be sure

switch Is In the locked or off posi
tion 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
accidents.

9) Remove adjusting keys or wrench
es 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

footing and balance at all times.

Proper footing and balance enable
better control d the tool in unexpected
situations.

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 work
piece to a stable platform.

Holding the work by hand or against

your body is unstable and may lead
to loss of control.

-2-

13) Oo not lore» tool. Use the correct

tool for your appllcetion.

The correct tool will do the job better
and safer at the rate for which it is
designed.

U) Do not use tool if switch does not

turn n on or off.

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 acces
sories, or storing the tool.

Such preventive safety measures
reduce №e risk of starting the tool acci
dentally.

16} Store idle tools out of reach of

children and other untrained per
sons.

Tools are dangerous in the harKls 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 con
nection from one terminal to
another.

Shorting the battery terminals togeth
er may cause ^rks, bums or a fire.

16) Maintain tools with care. Keep cut
ting tools sharp and clean.

Property 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 tooTs operations. H dam
aged, 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.

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
identical replacement parts. Follow
instructions In the Maintenance
section of this manual.

Use of unauthorized parts or failure to

follow Maintenance Instructions may
create a risk of shock or injury.

SPECIFIC SAFE
TY RULES

1) Hold tool by Insulated gripping
surfaces when performing an
operation where the cutting toert
may contact hidden wiring.

Contact with a “live’* wire will make
exposed metal parts of the toot live"
and shock the operator.

2) Wear ear protectors when using

the tool for extended periods.

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 reversing lever

when the main switch Is on.

The battery will discharge rapidly and
damage to the unit may occur.

5) If the bit becomes Jammed, Imme

diately turn the main switch off to
prevent an overload which can
damage the battery pack or motor.
Use reverse motion to loosen
Jammed bits.

6) When storing or carrying the tool,

set the reversing lever to the cert-

tar (switch lock) position.

7) Do not strain the tool by holding
the speed control trigger halfway
(speed control mode) so that the

1^ Do not store the tool and battery

pack in iocations where the tempera
ture may reach or exceed 122*'F
(50*H!?) (such a metal tool shed, or a

, car in the summer), which can lead to

deterioration of the storage battery.

16) Do r>ot charge battery pad( when the
temperature is BELOW 32°F (OX) or
ABOVE 104«F (40X). This is very
important.

17) Do not incinerate the battery pack. It
can explode in a fire.

18) Avoid dangerous environment. Do not

Battery Pack

For Appropriate use of NMMH
Battery Pack EY9210

• Charge the Ni-MH battery fully
before storage In order to ensure a
longer service iife.

• The ambient temperature range is
between OX and 40X.
If the battery pack is used when

the battery temperature is below
OX, the tool may fail to function
property. In that case, charge the
battery until charging te corri^ed
for appropriate functioning of the
battery.

Battery Pack Life

The rechargeable batteries have a
limited life. If operation time becomes
extremely short after recharging,
replace the battery pack with a new
one.

0 Battery charger

Note: Charge a new battery pack, or

a battery pack that has not
been used for a prolonged time,
for about 24 hours to bring the

• When charging, cooling fan in
the charger functions to coot
down the battery pack, and the
sound of fan can be heard. This
is normal. If this sound cannot
be heard, it is a malfunction.
Stop charging immediately and
confiult an au^orized dealer.

3. During charging, the charging

lamp wilt light up.
When the charge Is completed, an
internal electronic switch will
automatically be triggered to
prevent overcharging.

• Charging will not occur If the
battery pack is wann (for exam
ple, immediately after heavy­duty operation). The orange
standby lamp will light up until

the battery becomes cool.
Charging will then begin auto­maticalty.

4. When charging Is completed, the
charging lamp will start flashing

quickly.

5. When 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 standard
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 tight up.
After several minutes, the charg

ing lamp may flash quickly to
indicate the charging Is complet
ed.

6. If the charging lamp does not light
immediately 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 a cold battery (of about

5*C or less) is to be charged
in a warm room, leave the
battery in the room for at least
one hour and charge It when
It has warmed up to room
temperature. (Falliiig to do so
may result in less than a full
charge.)

• Cool down the charger when
charging more than two
battery packs consecutively.

•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.
