5.2 Safety precautions for chisels
a) Wear ear protection. Excessive noise may lead to a
loss of hearing.
b) Use the auxiliary handle supplied with the tool. Loss
of control of the tool may lead to injury.
c) Hold power tool by insulated gripping surfaces, when
performing an operation where the cutting acces-
sory may contact hidden wiring or its own cord. Cut-
ting accessory contacting a "live" wire may make expo-
sed metal parts of the power tool "live" and could give
the operator an electric shock.
5.3 Additional safety precautions
5.3.1 Personal safety
a) Breathing protection must be worn when the tool is
used without a dust removal system.
b) Exercise your fingers during pauses between work
to improve the blood circulation in your fingers.
c) To avoid tripping and falling when working, always
lead the sypply cord, extension cord and dust extrac-
tion hose away tho the rear.
d) The tool is not intended for use by children, by debil-
itated persons or those who have received no instruc-
tion or training.
e) Children must be instructed not to play with the tool.
f) Dust from material such as paint containing lead, some
wood species, minerals and metal may be harmful.
Contact with or inhalation of the dust may cause aller-
gic reactions and/or respiratory diseases to the oper-
ator or bystanders. Certain kinds of dust are classi-
fied as carcinogenic such as oak and beech dust espe-
cially in conjunction with additives for wood condi-
tioning (chromate, wood preservative). Material con-
taining asbestos must only be treated by specialists.
Where the use of a dust extraction device is possi-
ble it shall be used. To achieve a high level of dust
collection, use a suitable vacuum cleaner of the type
recommended by Hilti for wood dust and/or mineral
dust together with this tool. Ensure that the work-
place is well ventilated. The use of a dust mask of
filter class P2 is recommended. Follow national
requirements for the materials you want to work with.
5.3.2 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 elec-
trician 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, espe-
cially 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.
5.3.3 Power tool use and care
a) 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 .
b) In the event of a power faillure, switch the tool off
and unplug the supply cord. This prevents inadver-
tent starting when the power returns.
c) Hold tool by insulated gripping surfaces when per-
forming an operation where the cutting tool may
contact hidden wiring or its own cord. Contact with
a "live" wire will make exposed metal parts of the tool
"live" and shock the operator.
5.3.4 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.
5.3.5 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. Breath-
ing protection must be worn if no dust removal sys-
tem is used.
