Important Safety Instructions

WARNING: When using electric tools, basic safety precautions

should always be followed to reduce risk of fire, electric shock, and
personal injury, including the following:

READ ALL INSTRUCTIONS

Double Insulation

Double insulated tools are constructed throughout with two separate
layers of electrical insulation or one double thickness of insulation
between you and the tool’s electrical system. Tools built with this
insulation system are not intended to be grounded. As a result, your
tool is equipped with a two prong plug which permits you to use
extension cords without concern for maintaining a ground
connection.

NOTE: Double insulation does not take the place of normal safety
precautions when operating this tool. The insulation system is for
added protection against injury resulting from a possible electrical
insulation failure within the tool.

CAUTION: WHEN SERVICING USE ONLY IDENTICAL

REPLACEMENT PARTS. Repair or replace damaged cords.

Polarized Plugs

Polarized plugs (one blade is wider than the other) are used on
equipment to reduce the risk of electric shock. When provided, this
plug will fit in the polarized outlet only one way. If the plug does not
fit fully into the outlet, reverse the plug. If it still does not fit, contact a
qualified electrician to install the proper outlet. Do not change the
plug in any way.

Safety Instructions For All Tools

• KEEP WORK AREA CLEAN. Cluttered areas and benches invite

injuries.

• CONSIDER WORK AREA ENVIRONMENT. Don’t expose power

tools to rain. Don’t use power tools in damp or wet locations. Keep
work area well lit. Do not use tool in presence of flammable liquids
or gases.

• GUARD AGAINST ELECTRIC SHOCK. Prevent body contact

with grounded surfaces. For example; pipes, radiators, ranges, and
refrigerator enclosures.

• KEEP CHILDREN AWAY. Do not let visitors contact tool or

extension cord. All visitors should be kept away from work area.

• STORE IDLE TOOLS. When not in use, tools should be stored in

dry, and high or locked-up place — out of reach of children.

• DON’T FORCE TOOL. It will do the job better and safer at the

rate for which it was intended.

• USE RIGHT TOOL. Don’t force small tool or attachment to do the

job of a heavy-duty tool. Don’t use tool for purpose not intended.

• DRESS PROPERLY. Do not wear loose clothing or jewelry. They

can be caught in moving parts. Rubber gloves and non-skid
footwear are recommended when working outdoors. Wear
protective hair covering to contain long hair. Air vents often cover
moving parts and should also be avoided.

• USE SAFETY GLASSES. Also use face or dust mask if operation

is dusty.

• DON’T ABUSE CORD. Never carry tool by cord or yank it to

disconnect from receptacle. Keep cord from heat, oil, and sharp
edges.

• SECURE WORK. Use clamps or a vise to hold work. It’s safer than

using your hand and it frees both hands to operate tool.

• DON’T OVERREACH. Keep proper footing and balance at all

times.

• MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for

better and safer performance. Follow instructions for lubricating
and changing accessories. Inspect tool cords periodically and if
damaged, have repaired by authorized service facility. Inspect
extension cords periodically and replace if damaged. Keep
handles dry, clean, and free from oil and grease.

• DISCONNECT OR LOCK OFF TOOLS when not in use, before

servicing, and when changing accessories, such as blades, bits,
cutters.

• REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of

checking to see that keys and adjusting wrenches are removed
from tool before turning it on.

• AVOID UNINTENTIONAL STARTING. Don’t carry tool with finger

on switch. Be sure switch is off when plugging in.

• EXTENSION CORDS. Make sure your extension cord is in good

condition. When using an extension cord, be sure to use one
heavy enough to carry the current your product will draw. An
undersized cord will cause a drop in line voltage resulting in loss
of power and overheating. The following table shows the correct
size to use depending on cord length and nameplate ampere
rating. If in doubt, use the next heavier gage. The smaller the gage
number, the heavier the cord.

• OUTDOOR USE EXTENSION CORDS. When tool is used

outdoors, use only extension cords intended for use outdoors and
so marked.

• STAY ALERT. Watch what you are doing. Use common sense.

Do not operate tool when you are tired.

• CHECK DAMAGED PARTS. Before further use of the tool, a

guard or other part that is damaged should be carefully checked
to determine that it will operate properly and perform its intended
function. Check for alignment of moving parts, binding of moving
parts, breakage of parts, mounting, and any other conditions that
may affect its operation. A guard or other part that is damaged
should be properly repaired or replaced by an authorized service
center unless otherwise indicated elsewhere in this instruction
manual. Have defective switches replaced by authorized service
center. Do not use tool if switch does not turn it on and off.

• CAUTION: When drilling or driving into walls, floors or

wherever live electrical wires may be encountered, DO NOT
TOUCH ANY METAL PARTS OF THE TOOL! Hold the tool only by
insulated grasping surfaces to prevent electric shock if you drill or
drive into a live wire.

WARNING: Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities contains chemicals known to
cause cancer, birth 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 chromium from chemically-treated lumber (CCA).

Your risk from these exposures varies, depending on how often you do
this type of work. To reduce 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.

• Avoid prolonged contact with dust from power sanding,

sawing, grinding, drilling, and other construction activities.
Wear protective clothing and wash exposed areas with soap
and water. Allowing dust to get into your mouth, eyes, or lay on the

skin may promote absorption of harmful chemicals.

CAUTION: Wear appropriate hearing protection during use.

Under some conditions and duration of use, noise from this product
may contribute to hearing loss.

SAVE THESE INSTRUCTIONS

Motor

Be sure your power supply agrees with nameplate marking. 120 volts
AC means your tool may be operated only with alternating current
and never with direct current. Voltage decrease of more than 10% will
cause loss of power and overheating. All tools are factory tested; if
this tool does not operate, check the power supply.

Switch

To turn the tool on, depress the paddle switch that runs the length of
the tool, as shown in Figure 4. To turn the tool off, release the paddle.

Chuck

Open chuck jaws by aligning hole in chuck with an opening in the
chuck guard, and insert the chuck key through the opening and into
the chuck (Figure 1). Insert shank of bit about 3/4" (19mm) into
chuck. It’s important to tighten chuck with all three holes. To release
bit, turn key counterclockwise in just one hole.

Chuck Key Holder (Figure 2)

1. Push double-hole end of holder through slot in other end of holder.

2. Slip loop over electric plug and draw loop tight around cord.

3. Push ends of chuck key handle through two holes in end of holder.

Chuck Removal

Insert straight end of chuck key handle into chuck as shown in Figure

3. Using a wooden mallet or similar object, strike key sharply in a
counterclockwise direction. This will loosen the chuck so that it can
be unscrewed by hand.

Drilling

1. Always turn off tool and disconnect from power supply when
attaching or changing bits or accessories.

2. Use sharp drill bits only. For WOOD, use twist drill bits, spade bits,
power auger bits, or hole saws. For METAL, use high speed steel
twist drill bits or hole saws. For MASONRY, such as brick, cement,
cinder block, etc., use carbide-tipped bits

3. Be sure the material to be drilled is anchored or clamped firmly. If
drilling thin material, use a “back-up” block to prevent damage to
the material.

4. Always apply pressure in a straight line with the bit. Use enough
pressure to keep the drill bit biting, but do not push hard enough
to stall the motor or deflect the bit.

5. Hold tool firmly to control the twisting action of the drill.

6. IF DRILL STALLS, it is usually because it is being overloaded.
RELEASE TRIGGER IMMEDIATELY, remove drill bit from work,
and determine cause of stalling. DO NOT CLICK TRIGGER OFF

AND ON IN AN ATTEMPT TO START A STALLED DRILL –
THIS CAN DAMAGE THE DRILL.

7. To minimize stalling on breaking through the material, reduce
pressure on drill and ease the bit through the last fractional part
of the hole.

8. Keep the motor running when pulling the bit back out of a drilled
hole. This will help prevent jamming.

9. For optimum control and comfort, the drill may be grasped in one
of the following illustrated manners: Around the neck of the drill
using one or two fingers to operate the paddle switch as in
Figure 4, in an inverted position with the heel of the hand pushing
on the head of the drill and one or two fingers on the paddle switch

as in Figure 5, or holding the head of the drill with one hand and
operating the paddle switch with the other hand, holding the back
end of the drill as in Figure 6.

Drilling in Wood

Holes in wood can be made with the same twist drills used for metal.
These bits may overheat unless pulled out frequently to clear chips
from the flutes. For larger holes, use spade bits, power auger bits, or
hole saws. Work that is likely to splinter should be backed up with a
block of wood.

Drilling in Metal

Use a cutting lubricant when drilling metals. The exceptions are cast
iron and brass which should be drilled dry. The cutting lubricants
that work best are sulphurized cutting oil or lard oil; bacon grease will
also serve the purpose.

Drilling in Masonry

Use carbide tipped masonry bits at low speeds. Keep even force on
the drill but not so much that you crack the brittle materials. A
smooth, even flow of dust indicates the proper drilling rate.

Motor Brushes

Your tool will stop when the brushes wear out (down to about 3/16"
(5mm) long). This prevents damage to the motor.

Accessories

Recommended accessories for use with your tool are available at
extra cost from your local dealer or authorized service center.

RÈGLES DE SÉCURITÉ GÉNÉRALES

AVERTISSEMENT! Vous devez lire et comprendre toutes les
instructions. Le non-respect, même partiel, des instructions ci-après

entraîne un risque de choc électrique, d’incendie et/ou de blessures
graves.

CONSERVEZ CES INSTRUCTIONS.

Double isolation

Les outils à double isolation comportent deux couches distinctes
d’isolant électrique ou une double épaisseur d’isolant qui protègent
l’utilisateur contre les risques de blessures provenant du système
électrique de l’outil. Ce système de double isolation élimine le besoin
de mettre les outils à la terre. En effet, l’outil est muni d’une fiche à
deux broches, ce qui permet d’utiliser une rallonge ordinaire sans
avoir à se soucier d’assurer la mise à la terre.

NOTE : La double isolation ne dispense pas des mesures de sécurité
normales lors de l’utilisation de l’outil. Elle vise à procurer une
protection supplémentaire contre les blessures que peut entraîner
une défectuosité de l’isolant électrique à l’intérieur de l’outil.

MISE EN GARDE : LORS DE L’ENTRETIEN, N’UTILISER QUE

DES PIÈCES DE RECHANGE IDENTIQUES. Réparer ou remplacer
les cordons endommagés.

Fiche polarisée

Afin de réduire les risques de secousses électriques, l’outil est muni
d’une fiche polarisée (une lame plus large que l’autre). Ce genre de
fiche n’entre que d’une façon dans une prise polarisée. Lorsqu’on
ne peut insérer la fiche à fond dans la prise, il faut tenter de le faire
après avoir inversé les lames de côté. Si la fiche n’entre toujours
pas dans la prise, il faut communiquer avec un électricien certifié afin
qu’il installe une prise appropriée. Il ne faut en aucun cas modifier la
fiche.
