5 Safety instructions
5.1 General Power Tool Safety Warnings
a)
WARNING
Read all safety warnings and instructions. Failure
to follow the warnings and instructions may result
in electric shock, fire and/or serious injury. Save all
warnings and instructions for future reference.
The term “power tool” in the warnings refers to
your mains-operated (corded) power tool or batteryoperated (cordless) power tool.
5.1.1 Work area safety
Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
b) 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.
c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose
control.
a)
5.1.2 Electrical safety
Power tool plugs must match the outlet. Never
modify 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.
b) Avoid body contact with earthed or grounded
surfaces 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
carrying, 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
extension cord suitable for outdoor use. Use of
a cord suitable for outdoor use reduces the risk of
electric shock.
f) If operating a power tool in a damp location is
unavoidable, use a residual current device (RCD)
protected supply. Use of an RCD reduces the risk
of electric shock.
a)
5.1.3 Personal safety
Stay alert, watch what you are doing and use
common 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 personal protective equipment. Always wear
eye protection. Protective equipment such as dust
mask, non-skid safety shoes, hard hat, or hearing
a)
protection used for appropriate conditions will reduce
personal injuries.
c) Prevent unintentional starting. Ensure the switch
is in the off‐position before connecting to power
source and/or battery pack, picking up or carrying
the tool. Carrying power tools with your finger on the
switch or energising power tools that have the switch
on invites accidents.
d) Remove any adjusting key or wrench before turning 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
power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or
jewellery. 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 dust
collection can reduce dust-related hazards.
5.1.4 Power tool use and care
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
controlled with the switch is dangerous and must be
repaired.
c) Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures 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 maintained 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 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.

5.1.5 Service
a)
en
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.
5.2 Drill safety warnings
Wear ear protectors when impact drilling. Exposure to noise can cause hearing loss.
b) Use auxiliary handle(s), if supplied with the tool.
Loss of control can cause personal injury.
c) Hold power tool by insulated gripping surfaces,
when performing an operation where the cutting
accessory may contact hidden wiring or its own
cord. Cutting accessory contacting a "live" wire may
make exposed metal parts of the power tool "live"
and could give the operator an electric shock.
a)
5.3 Additional safety rules
5.3.1 Personal safety
During hand-held use, always hold the machine
securely with both hands on the grips provided.
Keep the grips dry, clean and free from oil and
grease.
b) Check that the side handle is tightened securely.
c) Assemble the parts of the mounting device correctly before attaching the machine. In order to
avoid the risk of collapse, it is important that the
parts are assembled correctly.
d) Attach the machine to the mounting device securely before beginning use. Movement of the machine on the mounting device could lead to loss of
control.
e) Place the mounting device on a solid, flat and level
surface. If the mounting device can slip or wobble,
the machine cannot be guided smoothly and safely.
f) Check the nature of the surface. Rough surfaces
may reduce holding power. Coatings or composite
materials may pull away from the surface while you
are working.
g) Do not overload the mounting device and do not
use it as a substitute for a ladder or platform.
Overloading the mounting device or standing on it
may shift its center of gravity to a higher position,
causing it to tip over.
h) Respiratory protection must be worn if the machine is used without a dust extraction system for
work that creates dust.
i) Improve the blood circulation in your fingers by
relaxing your hands and exercising your fingers
during breaks between working.
j) Avoid touching rotating parts. Switch the power
tool on only after bringing it into position at the
workpiece. Touching rotating parts, especially roa)
8
Printed: 08.07.2013 | Doc-Nr: PUB / 5069533 / 000 / 02
tating drill bits, discs or blades, etc. may lead to
injury.
k) When using the equipment, always lead the supply
cord, the extension cord and the water hose (if
applicable) away from the machine to the rear.
This will reduce the risk of tripping and falling over
the cord or hose while working.
l) Avoid skin contact with drilling slurry.
m) Wear protective gloves when changing core bits.
The core bit may become hot during use.
n) Children must be instructed not to play with the
machine.
o) The machine is not intended for use by children,
by debilitated persons or those who have received
no instruction or training.
p) WARNING: Some dust created by grinding, sanding, 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 lead-based paints, crystalline silica from bricks, concrete and other masonry
products and natural stone, arsenic and chromium
from chemically-treated 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 well-ventilated 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,
nose, eyes, or to remain on your skin may promote
absorption of harmful chemicals.
5.3.2 Power tool use and care
Secure the workpiece. Use clamps or a vice to
secure the workpiece. The workpiece is thus held
more securely than by hand and both hands remain
free to operate the machine.
b) Check that the core bits used are compatible with
the chuck system and that they are secured in the
chuck correctly.
c) Switch the machine off and unplug the supply
cord in the event of a power failure or interruption
in the electric supply. This will prevent accidental
restarting when the electric power returns.
a)
5.3.3 Electrical safety
a)
Before beginning work, check the working area
(e.g. using a metal detector) to ensure that no
concealed electric cables or gas and water pipes
are present. External metal parts of the machine may
become live, for example, when an electric cable is
damaged accidentally. This presents a serious risk of
electric shock.
b) Never operate the machine without the supplied
GFCI ground fault circuit interrupter (machines
without GFCI: Never operate the machine without
an isolating transformer). Test the GFCI each time
before use.
c) Check the machine’s supply cord at regular intervals and have it replaced by a qualified specialist
if found to be damaged. If the machine’s supply cord is damaged it must be replaced with
a specially-prepared supply cord available from
Hilti Customer Service. Check extension cords at
regular intervals and replace them if found to be
damaged. Do not touch the supply cord or extension cord if damaged while working. Disconnect
the supply cord plug from the power outlet. Damaged supply cords or extension cords present a risk
of electric shock.
b) Wear a protective mask during work that generates dust, e.g. dry drilling. Connect a dust removal system. Drilling in materials hazardous to
the health (e.g. asbestos) is not permissible.
c) Approval must be obtained from the site engineer
or architect prior to beginning drilling work. Drilling
work on buildings and other structures may influence
the statics of the structure, especially when steel
reinforcing bars or load-bearing components are cut
through.
d) It is recommended that rubber gloves and nonskid shoes are worn when working outdoors.
5.3.5 Personal protective equipment
5.3.4 Work area
a)
Ensure that the workplace is well ventilated. Exposure to dust at a poorly ventilated workplace may
result in damage to the health.
The user and any other persons in the vicinity must
wear ANSI Z87.1-approved eye protection, a hard
hat, ear protection, protective gloves and breathing
protection while the machine is in use.
