General Power Tool Safety Warnings
_WARNING! 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
1) WORK AREA SAFETY
a) Keep work area clean and well lit. Cluttered or dark areas
invite accidents.
b) 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.
c) Keep children and bystanders away while operating a
power tooL Distractions can cause you to lose control
2) ELECTRICAL SAFETY
a) Power tool plugs must match the outlet. Never modify
the plug in any way. Do not use any adapter plugs with
earthed (grounded) power tools. Unmodified plugs and
matching outlets will reduce risk of electric shock.
b) 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.
c) Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric
shock.
d) 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.
e) When operating apower tool outdoors, use an extension
cord suitable for outdoor use. Use of a cord suitable for
outdoor use reduces the risk of electric shock.
f) If operating apowertool in a damp location is unavoidable,
use a ground fault circuff interrupter (GFCl) protected
supply. Use of a GFCI reduces the risk of electric shock.

3) PERSONAL SAFETY
a) Stay alert, watch what you are doing and use common
sense when operating 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.
b) Use personal protective equipment. Always wear eye
protection. Protective equipment such as dust mask, non-
skid safety shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in
the off position before connecting to power source and/
or battery pack, picking up or carrying the tool. Carrying
power tools with your finger on the switch or energizing power
tools that have the switch on invites accidents.
d) 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.
e) Do not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situations.
f) Dress properly. Do not wear loose clothing or jewelry.
Keep your hair, clothing and gloves away from moving
parts. Loose clothes, jewelry or long hair can be caught in
moving parts.
g) 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.
4) POWER TOOL USE AND CARE
a) Do not force the power tool 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.
b) Do not use the power tool if the switch does not turn it
on and off. Any power tool that cannot be controlled with the
switch is dangerous and must be repaired.
c) 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.
d) 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.
e) Maintain power tools. Check for misalignment or binding
of moving parts, breakage of parts and any other
condition that may affect the power toors operation. If
damaged, have the power tool repaired before use. Many
accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained
cutting tools with sharp cutting edges are less likely to bind and
are easier to control
g) 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.
5) SERVICE
a) Have your power tool serviced by a qualified repair
person using only identical replacement parts. This will
ensure that the safety of the power tool is maintained.

Additional Specific Safety Instructions
• Use auxiliary handle(s), if supplied with the tool. Loss of
control can cause personal injury.
•Hold power tool by insulated gripping surfaces, when
performing an operation where the cutting accessory may
contact hidden wiring or its own cord. Cutting accessory
contacting a "live" wire may make exposed metal parts of the
power tool "live" and could give the operator an electric shock.
•Wear ear protectors with impact drills. Exposure to noise can
cause hearing loss.
•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.
• Wear safety goggles or other eye protection. Hammering and
drilling operations cause chips to fly. Flying particles can cause
permanent eye damage.
•Keep handles dry, clean, and free from oil and grease. This
will enable better control of the tool
• Air vents often cover moving parts and should be avoided.
Loose clothes, jewel/ery or long hair can be caught in moving parts.
• An extension cord must have adequate wire size (AWG
or American Wire Gauge) for safety. The smaller the gauge
number of the wire, the greater the capacity of the cable, that is
16 gauge has more capacity than 18 gauge. An undersized cord
will cause a drop in line voltage resulting in loss of power and
overheating. When using more than one extension to make up the
total length, be sure each individual extension contains at least the
minimum wire size. The following table shows the correct size to
use depending on cord length and nameplate ampere rating. If in
doubt, use the next heavier gauge. The smaller the gauge number,
the heavier the cord.

AWARNING: ALWAYS use safety glasses. Everyday eyeglasses
are NOT safety glasses. Also use face or dust mask if cutting
operation is dusty. ALWAYS WEAR CERTIFIED SAFETY EQUIPMENT"
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI $12.6 ($3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.
AWARNING: Some dust created by power sanding, sawing,
grinding, drilling, and other construction activities contains chemicals
known to the State of California 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.
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.
i_,WARNING: Use of this tool can generate and/or disperse dust,
which may cause serious and permanent respiratory or other
injury. Always use NIOSH/OSHA approved respiratory protection
appropriate for the dust exposure. Direct particles away from face
and body.
WARNING: Always wear proper personal hearing protection
that conforms to ANSI $12.6 ($3.19) during use. Under some
conditions and duration of use, noise from this product may
contribute to hearing loss.

NOTE" The first time the tool is run after changing speeds, you may
hear a click on start up. This is normal and does not indicate a problem.
Trigger Switch (Fig. 1)
Depressing the trigger switch (D)turns the tool on, releasing the trigger
switch turns the tool off.
VARIABLE SPEED
A variable speed trigger switch permits speed control--the farther the
trigger is depressed, the higher the speed of the drill.
NOTE" Use lower speeds for starting holes without a center punch,
drilling in metal, plastics or ceramics. Higher speeds are better for
drilling wood and composition boards.
Forward/Reverse Button (Fig. 1)
A forward/reverse button (C) determines the direction of the tool. It is
located in front of the trigger switch.
To select forward rotation, release the trigger switch (D) and depress
the forward/reverse button on the right side of the tool.

of the tool. When changing the position of the button, be sure the
trigger is released.
NOTE" The first time the tool is run after changing the direction of
rotation, you may hear a click on start up. This is normal and does not
indicate a problem.
OPERATION
_WARNING: To reduce the risk of injury, turn unit off
and disconnect ff from power source before installing and
removing accessories, before adjusting or when making
repairs. An accidental start-up can cause injury.
The bit rotates clockwise when the tool is in the forward position and
counterclockwise when the tool is in the reverse position. If the bit
binds, the tool will slow to a manageable level. Using proper hand
position, brace the side handle (I)or tool body against astud for better
support (Fig. 3).

Drilling
/_ WARNING: To reduce the risk of personal injury, ALWAYS
ensure workpiece is anchored or clamped firmly. If drilling thin
material, use a wood "back-up" block to prevent damage to the
material
1. Use sharp drill bits only. For WOOD, use twist drill bits, spade bits,
power auger bits, or hole saws. For METAL, use steel twist drill bits
or hole saws.
2. Always apply pressure in a straight line with the bit. Use enough
pressure to keep drill biting, but do not push hard enough to stall
the motor or deflect the bit.
3. Hold tool firmly with both hands to control the twisting action of the
drill.
4. IF DRILL STALLS, it is usually because it is being overloaded or
improperly used. RELEASE TRIGGER IMMEDIATELY, remove
drill bit from work, and determine cause of stalling. DO NOT
CLICK TRIGGER ON AND OFF IN AN ATTEMPT TO START
A STALLED DRILL -- THIS CAN DAMAGE THE DRILL.
5. To minimize stalling or breaking through the material, reduce
pressure on drill and ease the bit through the last fractional part of
the hole.
6. Keep the motor running when pulling the bit back out of a drilled
hole. This will help prevent jamming.
7. With variable speed drills there is no need to center punch
the point to be drilled. Use a slow speed to start the hole and
accelerate by squeezing the trigger harder when the hole is deep
enough to drill without the bit skipping out.
DRILLING IN METAL
Start drilling with slow speed and increase to full power while applying
firm pressure on the tool. A smooth even flow of metal chips indicates
the proper drilling rate. Use a cutting lubricant when drilling metals.
The exceptions are cast iron and brass which should be drilled dry.
NOTE: Large [5/16" (8 mm) to 1/2" (13 mm)] holes in steel can be
made easier ifa pilot hole [5/32" (4 mm) to 3/16" (5 mm)] is drilled first.
DRILLING IN WOOD
Start drilling with slow speed and increase to full power while applying
firm pressure on the tool. 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. Work that is apt to splinter
should be backed up with a block of wood.
Chuck Key Holder (Fig. 6, 7, 8)
1. Push double-hole end of holder through the slot in other end of
holder (Fig. 6).
2. Slip loop over electric plug and draw loop tight around cord
(Fig. 7).
3. Push ends of chuck key handle (long end first) through two holes
in end of holder (Fig. 8).
FIG. 6 FIG. 7
Keyed Chuck
FIG. 8
Open the chuck jaws by turning collar by hand and insert the shank of
the bit about 3/4" (19 mm) into chuck. Tighten the chuck collar by hand.
Place chuck key in each of the three holes, and tighten in clockwise
direction. It's important to tighten chuck with all three holes. To release
the bit, turn the chuck counterclockwise in just one hole, then loosen the
chuck by hand.

NOTE: When using hex shank or three sided shank bits be sure to align
the flat sides of the bit with the chuck jaws to ensure the bit is properly
engaged by the jaws.
REMOVAL OF KEYED CHUCK (FIG. 9)
Remove the left-handed clutch screw using a T25 torx wrench,
rotating clockwise to loosen.Tighten the chuck around the shorter
end of a hex wrench (not supplied) of 3/8" (10 mm) size. With the tool
braced securely, use a soft hammer and strike the hex wrench sharply
in the counterclockwise direction when viewed from the front of the
tool. This will loosen the chuck so that it can be removed by hand.
KEYED CHUCK INSTALLATION (FIG. 10)
Screw the chuck on by hand as far as it will go. Insert the shorter end
of a hex wrench (not supplied) of 3/8" (10 mm) size and strike it in
the clockwise direction with a soft hammer. Reinstall the left handed
clutch screw.

servir d'une rallonge convenant a cette application.
L'utilisation d'une rallonge conque pour I'exterieur reduira les
risques de choc dectrique.
f) S'il est impossible d'_viter rutilisation d'un outil
_lectrique clans un endroit humide, brancher routil clans
une prise ou sur un circuit d'alimentation dot_s d'un
disjoncteur de fuite a la terre (GFCl). L'uti/isation de ce type
de disjoncteur reduit les risques de choc dectrique.
3) SI_CURITI_ PERSONNELLE
a) Etre vigilant, surveiller le travail effectu_ et faire preuve
de jugement Iorsqu'un outil _lectrique est utilis_. Ne
pas utiliser d'outil _lectrique en cas de fatigue ou sous
rinfluence de drogues, d'alcool ou de m_dicaments. Un
simple moment d'inattention en utilisant un outil dectrique peut
entra_ner des blessures corporelles graves.
b) Utiliser des _quipements de protection individuelle.
Toujours porter une protection oculaire. L'uti/isation
d'equipements de protection comme un masque antipoussiere,
des chaussures antiderapantes, un casque de securite ou des
protecteurs auditifs Iorsque la situation le requiert reduira les
risques de blessures corporelles.
c) Emp_cher les d_marrages intempestifs. S'assurer que
rinterrupteur se trouve a la position d'arr_t avant de
relier routil a une source d'alimentation et/ou d'ins_rer
un bloc-piles, de ramasser ou de transporter routil.
Transporter un outil dectrique alors que le doigt repose sur
I'interrupteur ou brancher un outil dectrique dont I'interrupteur
est a la position de marche risque de provoquer un accident.
d) Retirer toute cl_ de r_glage ou cl_ avant de d_marrer
routil. Une c/e ou une c/e de reg/age attachee a une pattie
pivotante de I'outil dectrique peut provoquer des blessures
corporelles.
e) Ne pas trop tendre les bras. Conserver son _quilibre en
tout temps. Ce/a permet de mieux ma_triser /'outi/ dectrique
dans les situations imprevues.
f) S'habiller de mani_re appropriee. Ne pas porter de
v_tements amples ni de bijoux. Garder les cheveux, les
v_tements et les gants aI'_cart des pi_ces mobiles. Les
v_tements amp/es, /es bijoux ou /es cheveux longs risquent de
rester coinces dans les pieces mobiles.
g) Si des composants sont fournis pour le raccordement de
dispositifs de d_poussi_rage et de ramassage, s'assurer
que ceux-ci sont bien raccord_s et utilis_s. L'uti/isation
d'un dispositif de depoussierage peut reduire les dangers
engendres par les poussieres.
4) UTILISATION E'r ENTRETIEN D'UN OUTIL CLECTRIQUE
a) Ne pas forcer un outil _lectrique. Utiliser routil _lectrique
appropri_ a rapplication. L'outi/ dectrique approprie
effectuera un mei/leur travail, de faqon plus sore eta la vitesse
pour laquelle il a ete conqu.
13

b) Ne pas utiliser un outil _lectrique dont I'interrupteur
est d_fectueux. Tout outil dectrique dont I'interrupteur est
defectueux est dangereux et dolt _tre repare.
c) D_brancher la fiche de la source d'alimentation et/ou du
bloc-piles de I'outil _lectrique avant de faire tout r_glage
ou changement d'accessoire ou avant de ranger I'outil.
Ces mesures preventives reduisent les risques de demarrage
accidentel de I'outil dectrique.
d) Ranger /es outils _lectriques hors de la port_e des
enfants et ne permettre a aucune personne n'_tant
pas famili_re avec un outil _lectrique ou son mode
d'emploi d'utiliser cet outil. Les outils dectriques deviennent
dangereux entre les mains d'utilisateurs inexperimentes.
e) Entretien des outils _lectriques. V_rifier si les pi_ces
mobiles sont mal align_es ou coinc_es, si des pi_ces sont
bris_es ou pr_sentent toute autre condition susceptible
de nuire au bon fonctionnement de I'outil electrique.
En cas de dommage, faire r_parer I'outil _lectrique
avant toute nouvelle utilisation. Beaucoup d'accidents sont
causes par des outils dectriques mal entretenus.
f) S'assurer que /es outils de coupe sont aiguis_s et
propres. Les outils de coupe bien entretenus et affOtes
sont moins susceptibles de se coincer et sont plus faciles
ma_triser.
g) Utiliser I'outil _lectrique, /es accessoires, /es forets,
etc. conform_ment aux pr_sentes directives en tenant
compte des conditions de travail et du travail a effectuer.
L'utilisation d'un outil dectrique pour toute operation autre que
celle pour laquelle il a ete conquest dangereuse.
5) RI_PARATION
a) Faire r_parer I'outil _lectrique par un r_parateur
professionnel en n'utilisant que des pi_ces de rechange
identiques. Cela permettra de maintenir une utilisation
securitaire de I'outil dectrique.
Consignes de s_curit_ particuli_res
additionnelles
•Utiliser la/les poign_e(s) auxiliaire(s) si fournie(s) avec
I'outil. Une perte de contr61e de I'outil pourrait occasionner des
dommages corporels.
•Tenir I'outil par les surfaces isol_es pr_vues a cet effet
pendant toute utilisation ob I'organe de coupe pourraH
entrer en contact avec des ills _lectriques caches ou son
propre cordon. Tout contact de I'organe de coupe avec un fil
sous tension mettra les parties metalliques exposees de I'outil sous
tension et dectrocutera I'utilisateur.
•Pendant I'utilisation d'une perceuse apercussion, porter un
prot_ge-oreille. Le bruit en resultant pourrait occasionner une
perte de I'oui'e.
•Utiliser des serre-joints ou tout autre moyen pour fixer et
immobiliser le mat_riau sur une surface stable. Tenir la piece
la main ou contre son corps offre une stabilite insuffisante qui
pourrait vous en faire perdre le contr61e.
•Porter des lunettes de protection ou toute autre protection
oculaire. Le martelage et le perqage peuvent faire voltiger
des eclats. Ces particules volantes pourraient occasionner des
dommages oculaires permanents.
•Maintenir les poign_es propres et s_ches, exempts d'huile
ou de graisse. Cela permettra un meilleur contr6le de I'outil.
•Prendre des precautions bproximit_ des _vents, car ils
cachent des pi_ces mobiles. V_tements amp/es, bijoux ou
cheveux longs risquent de rester coinces dans ces pieces mobiles.
•Pour la s_curit_ de I'utilisateur, utiliser une rallonge de
calibre ad_quat (AWG, American Wire Gauge [calibrage
14

am_ricain normalis_ des fils _lectriques]). Plus le calibre est
petit, et plus sa capacite est grande. Un calibre 16, par exemple,
a une capacite superieure a un calibre 18. L'usage d'une rallonge
de calibre insuffisant causera une chute de tension qui entra_nera
perte de puissance et surchauffe. Si plus d'une rallonge est
utilisee pour obtenir une certaine Iongueur, s'assurer que chaque
rallonge presente au moins le calibre de fil minimum. Le tableau
ci-dessous illustre les calibres a utiliser selon la Iongueur de rallonge
et I'intensite nominale indiquee sur la plaque signaletique. En cas
de doute, utiliser le calibre suivant. Plus le calibre est petit, plus la
rallonge peut supporter de courant.

_A VERTISSEMENT : porter SYSTEMA TIQUEMENT des lunettes
de protection. Les lunettes courantes NE sont PAS des lunettes de
protection. Utiliser aussi un masque antipoussieres si la decoupe
doit en produire beaucoup. PORTER SYSTEMATIQUEMENT UN
EQUIPEMENT DE SECURITE HOMOLOGUE :
•Protection oculaire ANSI Z87.1 (CAN/CSA Z94.3) ;
• Protection auditive ANSI $12.6 ($3.19) ;
• Protection des voies respiratoires NIOSH/OSHA/MSHA.
_,AVERTISSEMENT :les scies, meules, ponceuses, perceuses
ou autres outils de construction peuvent produire des poussieres
contenant des produits chimiques reconnus par I'Etat califomien
pour causer cancers, malformations congenitales ou _tre nocifs au
systeme reproducteur. Parmi ces produits chimiques, on retrouve :
• Le plomb clans les peintures a base de plomb ;
• La silice cristallisee dans les briques et le ciment, ou autres
produits de maqonnerie ; et
• L'arsenic et le chrome dans le bois ayant subi un traitement
chimique.
Le risque associe a de telles expositions varie selon la frequence
laquelle on effectue ces travaux. Pour reduire toute exposition a ces
produits : travailler dans un endroit bien aere, en utilisant du materiel
de securite homologue, tel un masque antipoussieres specialement
conqu pour filtrer les particules microscopiques.
•Limiter toute exposition prolong_e avec les poussi_res
provenant du ponqage, sciage, meulage, perqage ou toute
autre activit_ de construction. Porter des v_tements de
protection et nettoyer a I'eau savonneuse /es parties du
corps expos_es. Le far de laisser la poussiere penetrer clans la
bouche, les yeux ou la peau peut favoriser I'absorption de produits
chimiques dangereux.
AAVERTISSEMENT :cet outil peut produire et/ou repandre
de la poussiere susceptible de causer des dommages serieux et
permanents au systeme respiratoire. Utiliser systematiquement un
appareil de protection des voies respiratoires homologue par le
NIOSH ou I'OSHA. Diriger les particules dans le sens oppose au
visage et au corps.
