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.

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

USB040-5

DO NOT let comfort or familiarity with
product (gained from repeated use)
replace strict adherence to sander safety
rules. If you use this tool unsafely or
incorrectly, you can suffer serious per­sonal injury.

1. Hold tool 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. Always use safety glasses or goggles. Ordinary
eye or sun glasses are NOT safety glasses.

3. Hold the tool firmly.

4. Do not leave the tool running. Operate the tool
only when hand-held.

5. This tool has not been waterproofed, so do not
use water on the workpiece surface.

6. Ventilate your work area adequately when you
perform sanding operations.

7. Use of this tool to sand some products, paints
and wood could expose user to dust containing
hazardous substances. Use appropriate respira­tory protection.

8. Be sure that there are no cracks or breakage on
the pad before use. Cracks or breakage may
cause a personal injury.

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
