GENERAL SAFETY RULES

(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

atmospheres, 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 insulation

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.

0 - 2,900/min. 0 - 1,200/min. 0 - 2,900/min. 0 - 1,200/min.

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 inattention 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

eliminates the need for

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.

2

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.

Holding 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 tool’s operation.
If damaged, have the tool serviced before
using. Many accidents 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 performed 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

unauthorized 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.

OPERATION

Hammer drilling operation

CAUTION:

• There is a tremendous and sudden twisting force

exerted on the tool/bit at the time of hole
break-through, when the hole becomes clogged
with chips and particles, or when striking
reinforcing rods embedded in the concrete. Always
use the side grip (auxiliary handle) and firmly hold
the tool by both side grip and switch handle during
operations. Failure to do so may result in the loss

of control of the tool and potentially severe injury.
When drilling in concrete, granite, tile, etc., move the
action mode changing lever to the position of
to use "rotation with hammering" action.
Be sure to use a tungsten-carbide tipped bit.
Position the bit at the desired location for the hole, then
pull the switch trigger. Do not force the tool. Light
pressure gives best results. Keep the tool in position and
prevent it from slipping away from the hole.
Do not apply more pressure when the hole becomes
clogged with chips or particles. Instead, run the tool at
an idle, then remove the bit partially from the hole. By
repeating this several times, the hole will be cleaned out
and normal drilling may be resumed.

002449

After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.

Drilling operation

When drilling in wood, metal or plastic materials, move
the action mode changing lever to the position
of

symbol to use "rotation only" action.

Drilling in wood

When drilling in wood, the best results are obtained with
wood drills equipped with a guide screw. The guide
screw makes drilling easier by pulling the bit into the
workpiece.

Drilling in metal

To prevent the bit from slipping when starting a hole,
make an indentation with a center-punch and hammer at
the point to be drilled. Place the point of the bit in the
indentation and start drilling.
Use a cutting lubricant when drilling metals. The
exceptions are iron and brass which should be drilled
dry.

CAUTION:

• Pressing excessively on the tool will not speed up

the drilling. In fact, this excessive pressure will only
serve to damage the tip of your bit, decrease the
tool performance and shorten the service life of the
tool.

• There is a tremendous force exerted on the tool/bit

at the time of hole break through. Hold the tool
firmly and exert care when the bit begins to break
through the workpiece.

• A stuck bit can be removed simply by setting the

reversing switch to reverse rotation in order to back
out. However, the tool may back out abruptly if you
do not hold it firmly.

• Always secure small workpieces in a vise or similar

hold-down device.

MAINTENANCE

CAUTION:

• Always be sure that the tool is switched off and

unplugged before attempting to perform inspection

or maintenance.

Cleaning vent holes

The tool and its air vents have to be kept clean.
Regularly clean the tool's air vents or whenever the
vents start to become obstructed.

Règles de sécurité générales

(POUR TOUS LES OUTILS)

MISE EN GARDE ! Assurez-vous d'avoir lu et
compris toutes les instructions. Il y a risque de choc

électrique, d'incendie et/ou de blessure grave si les
instructions ci-dessous ne sont pas respectées.

CONSERVEZ CE MODE
D'EMPLOI.

Zone de travail

1. Maintenez votre aire de travail propre et bien
éclairée. Les établis encombrés et les aires de

travail sombres ouvrent la porte aux accidents.

2. N'utilisez pas les outils électriques dans les

atmosphères explosives, par exemple en
présence de liquides, gaz ou poussières
inflammables. Les outils électriques produisent

des étincelles au contact desquelles la poussière
ou les vapeurs peuvent s'enflammer.

3. Tenez à distance les curieux, les enfants et les

visiteurs pendant que vous travaillez avec un
outil électrique. Ils pourraient vous distraire et

vous faire perdre la maîtrise de l'outil.

Sécurité en matière d'électricité

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. Gardez le
cordon à l'écart de la chaleur, de l'huile, des
bords tranchants et 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 personnelle

9. Restez alerte, attentif à vos gestes, et faites
preuve de bon sens lorsque vous utilisez un
outil électrique. Évitez d'utiliser l'outil lorsque
vous êtes fatigué ou sous l'influence de
drogues, d'alcool ou de médicaments. Tout

moment d'inattention pendant l'utilisation d'un
outil électrique comporte un risque de blessure
grave.
