Safety rules

1. General safety rules

-WARNING- Read all instructions! Failure to follow all

instructions listed below may result in electric shock,
fire and/or serious injury. The term "power tool" in all of
the warnings listed below refers to your mains operat­ed (corded) power tool or battery operated (cordless)
power tool.

SAVE THESE INSTRUCTIONS

1.1 Work area safety

a) Keep work area clean and well lit. Cluttered and

dark areas invite accidents.

b) Do not operate power tools in explosive atmos-

pheres, 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 operat-

ing a power tool. Distractions can cause you to lose

control.

1.2 Electrical safety
a) Power tool plugs must match the outlet. Never mod-

ify 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.

2

Printed: 07.07.2013 | Doc-Nr: PUB / 5070802 / 000 / 00

b) Avoid body contact with earthed or grounded sur-

faces 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 car-

rying, 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 a power tool outdoors, use an exten-

sion cord suitable for outdoor use. Use of a cord

suitable for outdoor use reduces the risk of electric
shock.

1.3 Personal safety

a) Stay alert, watch what you are doing and use com-

mon 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 safety equipment. Always wear eye protec-

tion. Safety equipment such as dust mask, non-skid

safety shoes, hard hat, or hearing protection used
for appropriate conditions will reduce personal
injuries.

c) Avoid accidental starting. Ensure the switch is in

the off position before plugging in. Carrying power

tools with your finger on the switch or plugging in
power tools that have the switch on invites acci­dents.

d) Remove any adjusting key or wrench before turn-

ing 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 pow-

er tool in unexpected situations.

f) Dress properly. Do not wear loose clothing or jew-

ellery. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewellery 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 these devices

can reduce dust related hazards.

1.4 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 con-

trolled with the switch is dangerous and must be
repaired.

c) Disconnect the plug from the power source before

making any adjustments, changing accessories, or
storing power tools. Such preventive safety mea-

sures 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 tool's 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 main-

tained 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 and in the
manner intended for the particular type of power
tool, 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.

1.5 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.

2. Specific safety rules and symbols

2.1 Personal safety

a) Wear ear protectors. Exposure to noise can cause

hearing loss.

b) Use auxiliary handles supplied with the tool. Loss

of control can cause personal injury.

c) Hold power 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.

d) Keep the grips dry, clean and free from oil and grease.

e) Exercise your fingers during pauses between work

to improve the blood circulation in your fingers.

f) Avoid contact with rotating parts. Switch the tool

on only once it has been brought into the working
position close to the workpiece.

g) Breathing protection must be worn when the tool is

used without a dust removal system for work that
creates dust.

h) To avoid tripping and falling when working, always

lead the sypply cord, extension cord and dust extrac­tion hose away to the rear.

i) Whendrilling or chiseling through-holes, check that

no person is present in the danger area immedi­ately behind the work surface.

j) Children must be instructed not to play with the

tool.

k) The tool is not intended for use by children,by

debilitated persons or those who have received
no instruction or training.

l) WARNING: Some dust created by grinding, sand-

ing, cutting and drilling contains chemicals known
to cause cancer, birth defects, infertility or other
reproductive harm; or serious and permanent res­piratory or other injury. Some examples of these

chemicals are: lead from leadbased paints, crystalline
silica from bricks, concrete and other masonry prod­ucts and natural stone, arsenic and chromium from
chemicallytreated lumber. Your risk from these expo­sures varies, depending on how often you do this type
of work. To reduce exposure to these chemicals,

the operator and bystanders should work in a well­ventilated area, work with approved safety equip­ment, such as respiratory protection appropriate
for the type of dust generated, and designed to fil­ter out microscopic particles and direct dust away
from the face and body. Avoid prolonged contact
with dust. Wear protective clothing and wash exposed
areas with soap and water. Allowing dust to get into

your mouth, eyes, or to remain on your skin may pro­mote absorption of harmful chemicals.

2.2 Power tool use and care

a) Secure the workpiece. Use clamps or a vice to hold

the workpiece in place. The workpiece is thus held

en

Printed: 07.07.2013 | Doc-Nr: PUB / 5070802 / 000 / 00

3

more securely than by hand and both hands remain
free to operate the tool.

b) Ensure that the insert tools used are equipped with

the appropriate connection end system and that
they are properly fitted and secured in the chuck.

c) In the event of a power faillure, switch the tool off

en

and unplug the supply cord. This prevents inadver­tent starting when the power returns.

d) In the event of an interruption in the electric supply

and before laying the tool down each time, check
that the lockbutton for sustained operation has been
released. Release the lockbutton if necessary. Fail-

ure to observe this point could cause the tool to start
unexpectedly when the power returns.

e) Do not apply an excessive quantity of grease to the

drill bit connection end. Excess grease may other-

wise be forced out of the chuck during operation.

2.3 Electrical safety
a) Before beginning work, check the working area (e.g.

with a metal detector) to ensure that no concealed
electric cables or gas and water pipes are present.

External metal parts of the tool may become live if,
for example, an electric cable is damaged inadvertenly.
This presents a serious risk of electric shock.

b) Check the condition of the supply cord and its plug

connections and have it replaced by a qualified elec­trician if damage is found. Check the condition of
the extension cord and replace it if damage is found.
Do not touch the supply in the event of it suffering
damage while working. Disconnect the supply cord
plug from the socket. Damaged supply cords and

extension cords present a risk of electric shock.

c) Dirty or dusty electric tools should thus be checked

at a Hilti service center at regular intervals, espe­cially if used frequently for working on conductive
materials. Dust (especially dust from conductive

materials) or dampness adhering to the surface of
the tool may, under unfavorable conditions, present
a risk of electric shock.

2.4 Work area

a) Ensure that the workplace is well lit.
b) Ensure that the workplace is well ventilated.

Poorly ventilated workplaces may be injurious to the
health due to exposeure to dust.

2.5 Personal protective equipment

The user and any other persons in the vicinity must
wear suitable eye protection, a hard hat, ear protection
and protective gloves when the tool is in use. Breath­ing protection must be worn if no dust removal sys­tem is used.
