Work area safety

Keep work area clean and well lit. Cluttered

or dark areas invite accidents.

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.

Keep children and bystanders away while
operating a power tool. Distractions can

cause you to lose control.

Electrical safety

Power tool plugs must match the outlet.
Never modify the plug in any way. Do not
us e any ada p t e r plugs w i th eart h e d
(grounded) power tools. Unmodified plugs

an d ma tchin g ou tlets wil l re d uce ris k o f
electric shock.

Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased risk

of electric shock if your body is earthed or
grounded.

Do not expose power tools to rain or wet

conditions. Water entering a power tool will

increase the risk of electric shock.

Do not abuse the cord. Never use the cord
for carrying, pulling or unplugging the power
tool. Keep cord away from heat, oil, sharp
edges or moving parts. Damaged or entangled

cords increase the risk of electric shock.

When operating a power tool outdoors,
use an extension cord suitable for outdoor
use. Use of a cord suitable for outdoor use

reduces the risk of electric shock.

If operating a power tool in a damp location
is unavoidable, use a Ground Fault Circuit
Interrupter (GFCI) protected supply. Use of

an GFCI reduces the risk of electric shock.

Personal safety

Stay alert, watch what you are doing and
us e c ommon se nse when o pera ting a
power tool. Do not use a power tool while
you are tired or under the influence of drugs,
alcohol or medication. A moment of inattention

while operating power tools may result in
serious personal injury.

Use personal protective equipment. Always
wear eye protection. Protective equipment

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.

such as dust mask, non-skid safety shoes, hard
h

at, or hearing protection used for appropriate

conditions will reduce personal injuries.

Prevent unintentional starting. Ensure the
sw itch is in the off- posi tion be fore
connecting to power source and / or battery
pa ck, pic king up or ca rryi ng the too l.

Carrying power tools with your finger on the
switch or energizing power tools that have the
switch on invites accidents.

Remove any adjusting key or wrench before
turning the power tool on. A wrench or a

key left attached to a rotating part of the power
tool may result in personal injury.

Do not overreach. Keep proper footing and
balance at all times. This enables better

co n trol of the power too l in unexp e cted
situations.

Dress properly. Do not wear loose clothing
or jewelry. Keep your hair, clothing and
gloves away from moving parts. Loos e

clothes, jewelry or long hair can be caught in
moving parts.

If devices are provided for the connection
of dust extraction and collection facilities,
ensure these are connected and properly
used. Use of dust collection can reduce dust-

related hazards.

Power tool use and care

Do not for ce th e pow er too l. Use the
correct power tool for your application. The

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

Do not use the power tool if the switch does
not turn it on and off. Any power tool that

ca n n o t be control l e d with the switc h is
dangerous and must be repaired.

Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such

preventive safety measures reduce the risk of
starting the power tool accidentally.

Store idle power tools out of the reach of
children and do not allow persons unfamiliar
with the power tool or these instructions to
operate the power tool. Power tools are

dangerous in the hands of untrained users.

Maintain power tools. Check for misalignment
or binding of moving parts, breakage of
parts and any other condition that may
affect the power tool’s operation. If damaged,
have the power tool repaired before use.

Ma n y a c c i dents are caused by po o r l y
maintained power tools.

Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to
control.

Use the power tool, accessories and tool
bits etc. in accordance with these instructions,
taking into account the working conditions
and the work to be performed. Use of the

power tool for operations different from those
intended could result in a hazardous situation.

Battery tool use and care

Recharge only with the charger specified
by th e ma nufa cturer. A cha rger tha t is

suitable for one type of battery pack may
create a risk of fire when used with another
battery pack.

Use power too ls only with specifically
designated battery packs. Use of any other

battery packs may create a risk of injury and
fire.

When battery pack is not in use, keep it
away from other metal objects like paper
clips, coins, keys, nails, screws, or other
small m e t a l objects that c a n make a
connection from one terminal to another.

Shorting the battery terminals together may
cause burns or a fire.

Under abusive conditions, liquid may be
ejected from the battery; avoid contact. If
contact accidentally occurs, flush with
water. If liquid contacts eyes, additionally
seek medical help. Liquid ejected from the

battery may cause irritation or burns.

Service

Have your power tool serviced by a qualified
re p a i r pe r son u s i n g on l y id e ntical
replacement parts. This will ensure that the

safety of the power tool is maintained.

Safety Rules for Cordless Drill/Drivers

Use clamps or another practical way to
s

ecure and support the workpiece to a

stable platform. Holding the work by hand or

against your body leaves it unstable and may
lead to loss of control.

Do not drill, fasten or break into existing
walls or other blind areas where electrical
wi r ing may e x ist. If t h is situ a tion is

unavoidable, disconnect all fuses or circuit
breakers feeding this worksite.

Al w ays we ar saf e ty go g gles o r eye
protection when using this tool. Use a dust
mask or respirator for applications which
generate dust.

Use thick cushioned gloves and limit the
exposure t ime by t aking fre que nt rest
periods. Vibration caused by hammer-drill

action may be harmful to your hands and arms.

Secure the material being drilled. Never
ho ld it in yo u r hand or across le g s.

Unstable support can cause the drill bit to bind
causing loss of control and injury.

Disconnect battery pack from tool before
maki ng any a sse mbly, ad jus tments or
changing accessories. S uch preventive

safety measures reduce the risk of starting the
tool accidentally.

Position yourself to avoid being caught
between the tool or side handle and walls
or posts. Should the bit become bound or

jammed in the work, the reaction torque of the
tool could crush your hand or leg.

If the bit becomes bound in the workpiece,
r

elease the trigger immediately, reverse the
direction of rotation and slowly squeeze
the trigger to back out the bit. Be ready for

a strong reaction torque. The drill body will
tend to twist in the opposite direction as the
drill bit is rotating.

Do not grasp the tool or place your hands
too close to the spinning chuck or drill bit.

Your hand may be lacerated.

When installing a drill bit, insert the shank
of the bit well within the jaws of the chuck.

If the bit is not inserted deep enough, the grip
of the jaws over the bit is reduced and the loss
of control is increased.

Do not use dul l or d a maged bit s and
accessories. Dull or damaged bits have a

greater tendency to bind in the workpiece.

When removing the bit from the tool avoid
contact with skin and use proper protective
gloves when grasping the bit or accessory.

Accessories may be hot after prolonged use.

Ch eck to see tha t ke ys and adju s ting
wrenches are removed from the drill before
switching the tool "ON". Keys or wrenches

can fly away at high velocity striking you or a
bystander.

Do not run the tool while carrying it at your
si de. A spin ning dril l bi t c o uld becom e

entangled with clothing and injury may result.

Use auxiliary handle(s) if supplied with the
tool. Loss of control can cause personal injury.

Hold powe r too l by insulate d grippi ng
surfaces, when performing an operation
where the cutting accessory may contact
hidden wiring. Cutting accessory contacting a

"live" wire may make exposed metal parts of
th e po wer tool "liv e" a nd c ould give the
operator an electric shock.

Use clamps or another practical way to
secure and support the workpiece to a

GFCI and personal protection devices like
electrician’s rubber gloves and footwear will
further enhance your personal safety.

Do not use AC only rated tools with a DC
power supply. While the tool may appear to

work, the electrical components of the AC
rated tool are likely to fail and create a hazard
to the operator.

Keep handles dry, clean and free from oil
and grease. Slippery hands cannot safely

control the power tool.

Develop a periodic maintenance schedule
for your tool. When c leaning a tool be
careful not to disassemble any portion of
th e tool sin ce inte rnal wir es may be
misplaced or pinched or safety guard return
sp ring s may be impro perl y mou nted .

Certain cleaning agents such as gasoline,
carb on tetra chl ori de, ammo nia , etc . may
damage plastic parts.

Ensure the switch is in the off position
before inserting battery pack. Inserting the

battery pack into power tools that have the
switch on invites accidents.

Some du st created by

power sanding, sawing,
grinding, drilling, and other construction
activities contains chemicals known to
ca use ca ncer , b i rth defects or other
reproductive harm. Some examples of
these chemicals are:

• Lead from lead-based paints,

• Crystalline silica from bricks and cement and

other masonry products, and

• Arsenic and chrom ium from chemically -

treated lumber.

Yo u r risk f r om the s e exposu r e s varie s ,
depending on how often you do this type of
work. To r educe your exposure to these
chemicals: work in a well ventilated area, and
work with approved safety equipment, such as
those dust masks that are specially designed
to filter out microscopic particles.

Additional Safety Warnings

Such preventive safety measures reduce the
r

isk of starting the tool accidentally.

Position yourself to avoid being caught
between the tool or side handle and walls
or posts. Should the bit become bound or

jammed in the work, the reaction torque of
the tool could crush your hand or leg.

If the bit be c o m e s b o u n d in the
workpiece, release th e tr i g g e r
im m ediat e ly, r e verse the dire c tion o f
rotation and slowly squeeze the trigger to
back out the bit. Be ready for a strong

reaction torque. The drill body will tend to
twist in the opposite direction as the drill bit is
rotating.

Do not grasp the tool or place your hands
too close to the spinning chuck or drill
bit. Your hand may be lacerated.

When installing a bit, insert the shank of
the bit well within the chuck. If the bit is

not inserted deep enough, the grip of the
c

huck over the bit is reduced and the loss of
control is increased. After bit insertion, pull
on bit to ensure it is locked.

Do not u se du l l or dam a ged b i t s an d
accessories. Dull or damaged bits have a

greater tendency to bind in the workpiece.

When removing the bit from the tool avoid

DRIVING NUTS AND BOLTS

Variable speed control must be used with
caution for driving nuts and bolts with socket
set attach ments. The technique is to start
slowly, increasing speed as the nut or bolt runs
down. Set the nut or bolt snugly by slowing the
drill to a stop. If this procedure is not followed,
the tool will have a tendency to torque or twist
in your hands when the nut or bolt seats.

DRILLING

You will extend the life of your bits and do
neater work if you always put the bit in contact
with the work before pulling the trigger. During
the oper a tion, hold the tool firmly and exert
light, steady pressure. Too much pressure at
low speed will stall the tool. Too little pressure
will keep the bit from cutting and cause excess
friction by sliding over the surface. This can be
damaging to both tool and bit.

DRILLING WITH VARIABLE SPEED

The variable speed trigger allows you to slowly
increase RPM. By using a slow starting speed,
you are able to keep the bit from “wander ing”.
You can increase the speed as the bit “bites”
into the work by squeezing the trigger.

DRIVING WITH VARIABLE SPEED

Variable speed drills will double as a power
screwdriver by using a screwdriver bit. Prior to
driving screws, pilot and clearance holes should
be drilled. Place the threaded end of the screw
in the pilot or clearance hole and start driving
the screw slowly, increasing the speed as the
screw runs down. Set the screw snugly by
slowing to a stop.

FASTENING WITH SCREWS

The procedure shown in Fig. 12 will enable
you to fasten materials together using your
drill without stripping, splitting or separating
the material.

First, clamp the pieces together and drill the
hole 2/3 the diameter of the screw. If the
material is soft, drill on ly 2/3 the prop er
length. If it is hard, drill the entire length.

Second, unclamp the pieces and drill the
hole in the top piece of wood again to the
same diameter as the shank of the screw.

Third, if flat head screw is used, countersink
the hole to make the screw flush with the
surface. Realign the holes on the two pieces
and apply even pressure when driving the
screw. The screw shank clearance hole in
the first piece allows the screw head to pull
the pieces tightly together.

The adjustable screw drill accessory will do
all of these operations quickly and easily.
Screw drills are available for screw sizes No.
6, 8, 10 and 12.

Operating Tips

-12-

TEMPERATURE OVERLOAD

P

ROTECTION

Av o id usi ng bat t ery ope rated tools
continuously, for long periods of time, while
subjecting the tool to overload conditions, such
as drilling with large diameter accessories into
hard materials. Using battery powered tools at
extr eme l oads, may cause the battery to
exceed its allowable operating temperature
range. When the battery exceeds nor mal
operating temperature caused by overload, the
speed of the tool may be reduced and the tool
may appear to lose power. To regain the tool's
full performance, the battery must be allowed

to cool, until the operating temperature returns
t

o normal.

RAPID SHUT-OFF (KICK BACK CONTROL)

To ensure better control of the tool during
operation, this tool is design to shut-off while in
us e if a sud den or un e xpect e d bin d up
situation occurs. Bind up occurs when the bit
gets jammed during operation, which forces
the bit to stop spinning abruptly. If this occurs,
the tool will shut down and the Rapid Shut-off
will be indicated by a flashing LED on the tool.
This feature can only be activated when the
tool is running at maximum speed.

Before using an

accessory, be certain that
its maximum safe operating speed is not
exceeded by the nameplate speed of the
tool. Do not exceed the recommended wheel
diameter.

SANDING AND POLISHING

Fine sanding and polishing re quire “touch”.
Select the most efficient speed.

When using polishing bonnets, alway be sure
the excess string that secures the bonnet is
tucked well within the bonnet during operation.

WIRE BRUSHES

Work with brushes requires high speeds.

BRUSHING PRESSURE

1. Let the tips of a wire brush do the work.
Operate the brush with the lightest pressure
so only the tips of the wire come in contact
with the work.

2. If heavier pressures are used, the wires
will be overstressed, resulting in a wiping
action; and if this is continued, the life of the
brush will be shortened due to wire fatigue.

3. Apply the brush to the work in such a way
that as much of the brush face as possible is
in full contact with the work. Applying the
side or edge of the brush to the work will
result in wire breakage and shortened brush
life.

CORRECT: Wire tips doing the work.

INCORRECT: Excessive pressure can cause wire breakage.

DRILL BITS

A

lways inspect drill bits for excessive wear. Use

only bits that are sharp and in good condition.

TWIST BITS: Ava ila ble with straight and
reduced shanks for wood and light duty metal
drilling. High speed bits cut faster and last
longer on hard ma terials.

CARBIDE TIPPED BITS: Used for drilling
stone, con crete, plaster, cement and other
unusually hard nonmetals. Use continuous
heavy feed pres sure when employing carbide
tip bits.

DRILLING WOOD

Be certain workpiece is clamped or anchored
firm ly. Always apply pressure in a straight line
with the drill bit. Maintain enough pressure to
keep the drill “biting”.

When drilling holes in wood, twist bits can be
used. Twist bits may overheat unless pulled out
frequently to clear chips from flutes.

Use a “back-up” block of wood for work that is
likely to splinter, such as thin materials.

You will drill a cleaner hole if you ease up on
t

he pressure just before the bit breaks through
the wood. Then complete the hole from the
back side.

DRILLING METAL

There are two rules for drilling hard materials.
First, the harder the material, the greater the
pres sure you need to apply to the tool. Second,
the harder the material, the slower the speed.
Here are a couple of tips for drilling in metal.
Lubri cate the tip of the bit occasionally with
cutting oil except when drilling soft metals such
as alu minum, cop per or cast iron. If the hole to
be drilled is fairly large, drill a smaller hole first,
then enlarge to the required size, it’s often
fa ster in the lon g run. Mai n tain eno ugh
pressure to assure that the bit does not just
spin in the hole. This will dull the bit and greatly
shorten its life.

DRILLING MASONRY

Soft materials such as brick are relatively easy
to drill. Concrete however, will require much
more pressure to keep the bit from spinning. Be
sure to use carbide tip bits for all masonry work.
