d)
Keep the grips dry, clean and free from oil and
grease.
e)
Breathing protection must be worn if the power
tool is used without a dust removal system for
work that creates dust.
f)
Improve the blood circulation in your fingers by
relaxing your hands and exercising your fingers
during breaks between working.
g)
Avoid touching rotating parts. Switch the power
tool on only after bringing it into position at the
workpiece.
Touching rotating parts, especially
rotating insert tools, may lead to injury.
h)
Always lead the supply cord and extension cord
away from the power tool to the rear while
working.
This helps to avoid tripping over the
cord while working.
i)
When using the power tool for mixing, set the
function selector switch to “Hammer drilling”
and wear protective gloves.
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 per-
manent respiratory or other injury.
Some exam-
ples 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 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, eyes, or to remain on your skin
may promote absorption of harmful chemicals.
3.2.2 Power tool use and care
a)
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 power tool.
b)
Check that the insert tools used are compatible
with the chuck system and that they are secured
in the chuck correctly.
3.2.3 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
power tool may become live, for example, when
an electric cable is damaged accidentally. This
presents a serious risk of electric shock.
b)
Check the power tool’s supply cord at regular
intervals and have it replaced by a qualified
specialist if found to be damaged. Check exten-
sion cords at regular intervals and replace them
if found to be damaged. Do not touch the supply
cord or extension cord if it is damaged while
working. Disconnect the supply cord plug from
the power outlet.
Damaged supply cords or
extension cords present a risk of electric shock.
c)
Dirty or dusty power tools which have been
used frequently for work on conductive materi-
als should be checked at regular intervals at a
Hilti Service Center.
Under unfavorable circum-
stances, dampness or dust adhering to the sur-
face of the power tool, especially dust from con-
ductive materials, may present a risk of electric
shock.
d)
When working outdoors with an electric tool
check to ensure that the tool is connected to the
electric supply by way of a ground fault circuit
interrupter (GFCI) with a rating of max. 30 mA
(tripping current).
Use of a ground fault circuit
interrupter reduces the risk of electric shock.
e)
Use of a ground fault circuit interrupter (GFCI)
with a maximum tripping current of 30 mA is
recommended.
3.2.4 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.
b)
If the work involves breaking right through, take
the appropriate safety measures at the opposite
side.
Parts breaking away could fall out and / or
fall down and injure other persons.
3.2.5 Personal protective equipment
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 breath-
ing protection while the power tool is in use.
