GENERAL SAFETY RULES
USA002-2
(For All Tools)
WARNING:
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 well lit. Cluttered
benches and dark areas invite accidents.
2. Do not operate power tools in explosive atmo-
spheres, 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.
Electrical Safety
4. Double insulated tools are equipped with a
polarized plug (one blade is wider than the
other.) This plug will fit in a polarized outlet only
one way. If the plug does not fit fully in the outlet,
reverse the plug. If it still does not fit, contact a
qualified electrician to install a polarized outlet.
Do not change the plug in any way. Double insula-
tion eliminates the need for the three wire
grounded power cord and grounded power supply
system.
5. Avoid body contact with grounded surfaces
such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if
your body is grounded.
6. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the
risk of electric shock.
7. Do not abuse the cord. Never use the cord to
carry the tools or pull the plug from an outlet.
Keep cord away from heat, oil, sharp edges or
moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric
shock.
8. When operating a power tool outside, use an
outdoor extension cord marked “W-A” or “W”.
These cords are rated for outdoor use and reduce
the risk of electric shock.
Personal Safety
9. Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use tool while tired or under the influence of
drugs, alcohol, or medication. A moment of inat-
tention while operating power tools may result in
serious personal injury.
10. Dress properly. Do not wear loose clothing or
jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose
clothes, jewelry, or long hair can be caught in moving parts.
11. Avoid accidental starting. Be sure switch is off
before plugging in. Carrying tools with your finger
on the switch or plugging in tools that have the
switch on invites accidents.
12. Remove adjusting keys or wrenches 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.
13. Do not overreach. Keep proper footing and balance at all times. Proper footing and balance
enables better control of the tool in unexpected situations.
14. Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat, or
hearing protection must be used for appropriate conditions. Ordinary eye or sun glasses are NOT eye
protection.
2
Tool Use and Care
15. Use clamps or other practical way to secure and
support the workpiece to a stable platform. Hold-
ing the work by hand or against your body is unstable and may lead to loss of control.
16. Do not force tool. Use the correct tool for your
application. The correct tool will do the job better
and safer at the rate for which it is designed.
17. Do not use tool if switch does not turn it on or
off. Any tool that cannot be controlled with the
switch is dangerous and must be repaired.
18. Disconnect the plug from the power source
before making any adjustments, changing
accessories, or storing the tool. Such preventive
safety measures reduce the risk of starting the tool
accidentally.
19. Store idle tools out of reach of children and
other untrained persons. Tools are dangerous in
the hands of untrained users.
20. Maintain tools with care. Keep cutting tools
sharp and clean. Properly maintained tools with
sharp cutting edges are less likely to bind and are
easier to control.
21. Check for misalignment or binding of moving
parts, breakage of parts, and any other condition
that may affect the tools operation. If damaged,
have the tool serviced before using. Many acci-
dents are caused by poorly maintained tools.
22. Use only accessories that are recommended by
the manufacturer for your model. Accessories
that may be suitable for one tool, may become hazardous when used on another tool.
SERVICE
23. Tool service must be performed only by qualified
repair personnel. Service or maintenance per-
formed by unqualified personnel could result in a risk
of injury.
24. When servicing a tool, use only identical
replacement parts. Follow instructions in the
Maintenance section of this manual. Use of unau-
thorized parts or failure to follow Maintenance
instructions may create a risk of electric shock or
injury.
USE PROPER EXTENSION CORD: 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. Table 1 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.

SPECIFIC SAFETY RULES
USB009-2
DO NOT let comfort or familiarity with
product (gained from repeated use)
replace strict adherence to hammer
safety rules. If you use this tool unsafely
or incorrectly, you can suffer serious personal injury.
1. Hold tools by insulated gripping surfaces when
performing an operation where the cutting tool
may contact hidden wiring or its own cord. Con-
tact with a “live” wire will make exposed metal parts
of the tool “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. Wear a hard hat (safety helmet), safety glasses
and/or face shield. Ordinary eye or sun glasses
are NOT safety glasses. It is also highly recommended that you wear a dust mask and thickly
padded gloves.
4. Be sure the bit is secured in place before operation.
5. Under normal operation, the tool is designed to
produce vibration. The screws can come loose
easily, causing a breakdown or accident. Check
tightness of screws carefully before operation.
6. In cold weather or when the tool has not been
used for a long time, let the tool warm up for a
while by operating it under no load. This will
3
loosen up the lubrication. Without proper warmup, hammering operation is difficult.
7. Always be sure you have a firm footing.
Be sure no one is below when using the tool in
high locations.
8. Hold the tool firmly with both hands.
9. Keep hands away from moving parts.
10. Do not leave the tool running. Operate the tool
only when hand-held.
11. Do not point the tool at any one in the area when
operating. The bit could fly out and injure someone seriously.
12. Do not touch the bit or parts close to the bit
immediately after operation; they may be
extremely hot and could burn your skin.
13. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation
and skin contact. Follow material supplier safety
data.

RÈGLES DE SÉCURITÉ
GÉNÉRALES
USA002-2
(Pour tous les outils)
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
Aire de travail
1. Veillez à ce que l’aire de travail soit propre et
bien éclairée. Le désordre et le manque de lumière
favorisent les accidents.
2. N’utilisez pas d’outils électriques dans une
atmosphère explosive, par exemple en présence
de liquides, de gaz ou de poussières
inflammables. Les outils électriques créent des
étincelles qui pourraient enflammer les poussières
ou les vapeurs.
3. Tenez à distance les curieux, les enfants et les
visiteurs pendant que vous travaillez avec un
outil électrique. lls pourraient vous distraire et vous
faire une fausse manoeuvre.
Sécurité électrique
4. Les outils à double isolation sont équipés d’une
fiche polarisée (une des lames est plus large que
l’autre), qui ne peut se brancher que d'une seule
façon dans une prise polarisée. Si la fiche
n’entre pas parfaitement dans la prise, inversez
sa position ; si elle n’entre toujours pas bien,
demandez à un électricien qualifié d’installer une
prise de courant polarisée. Ne modifiez pas la
fiche de l’outil. La double isolation élimine le
besoin d’un cordon d’alimentation à trois fils avec
mise à la terre ainsi que d’une prise de courant mise
à la terre.
5. Évitez tout contact corporel avec des surfaces
mises à la terre (tuyauterie, radiateurs,
cuisinières, réfrigérateurs, etc.). Le risque de
choc électrique est plus grand si votre corps est en
contact avec la terre.
6. N’exposez pas les outils électriques à la pluie ou
à l’eau. La présence d’eau dans un outil électrique
augmente le risque de choc électrique.
7. Ne maltraitez pas le cordon. Ne transportez pas
l’outil par son cordon et ne débranchez pas la
fiche en tirant sur le cordon. N’exposez pas le
cordon à la chaleur, à des huiles, à des arêtes
vives ou à des pièces en mouvement.
Remplacez immédiatement un cordon
endommagé. Un cordon endommagé augmente le
risque de choc électrique.
8. Lorsque vous utilisez un outil électrique à
l’extérieur, employez un prolongateur pour
l’extérieur marqué “W-A” ou “W”. Ces cordons
sont faits pour être utilisés à l’extérieur et réduisent
le risque de choc électrique.
Sécurité des personnes
9. Restez alerte, concentrez-vous sur votre travail
et faites preuve de jugement. N’utilisez pas un
outil électrique si vous êtes fatigué ou sous
l'influence de drogues, d’alcool ou de
médicaments. Un instant d’inattention suffit pour
entraîner des blessures graves.
10. Habillez-vous convenablement. Ne portez ni
vêtements flottants ni bijoux. Confinez les
cheveux longs. N’approchez jamais les
cheveux, les vêtements ou les gants des pièces
en mouvement. Des vêtements flottants, des bijoux
ou des cheveux longs risquent d’être happés par
des pièces en mouvement.
11. Méfiez-vous d’un démarrage accidentel. Avant
de brancher l’outil, assurez-vous que son
interrupteur est sur ARRÊT. Le fait de transporter
un outil avec le doigt sur la détente ou de brancher
un outil dont l’interrupteur est en position MARCHE
peut mener tout droit à un accident.
