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.

2

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

USB002-2

DO NOT let comfort or familiarity with
product (gained from repeated use)
replace strict adherence to hammer drill
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. Always be sure you have a firm footing. Be sure

no one is below when using the tool in high loca­tions.

3. Hold the tool firmly with both hands. Always use
the side grip.

4. Keep hands away from rotating parts.

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

3

6. Do not touch the bit or the workpiece immedi­ately after operation; they may be extremely hot
and could burn your skin.

7. Some material contains chemicals which may be
toxic. Take caution to prevent working dust inha­lation and skin contact. Follow material supplier
safety data.

The depth gauge is convenient for drilling holes of uni­form depth. Loosen the side grip and insert the depth
gauge into the hole in the side grip. Adjust the depth
gauge to the desired depth and tighten the side grip.

NOTE:

• The depth gauge cannot be used at the position

where the depth gauge strikes against the tool
body.

OPERATION

Hammer drilling operation

CAUTION:

• There is a tremendous and sudden twisting force

exerted on the tool/bit at the time of hole break­through, 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 symbol
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.

Blow-out bulb (optional accessory)

001302

1. Blow-out bulb

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.

To maintain product SAFETY and RELIABILITY, repairs,
carbon brush inspection and replacement, any other
maintenance or adjustment should be performed by Mak­ita Authorized or Factory Service Centers, always using
Makita replacement parts.

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 électri-

que 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 che-
