5.2 Additional safety precautions
5.2.1 Personal safety
a) Wear ear protectors. Exposure to noise can cause
hearing loss.
b) Use the auxiliary handle supplied with the tool.
Loss of control of the tool may lead to injury.
c) Breathing protection must be worn when the tool is
en
used without a dust removal system for work that
creates dust.
d) To avoid tripping and falling when working, always
lead the sypply cord, extension cord and dust extrac-
tion hose away tho the rear.
e) The tool is not intended for use by children, by debil-
itated persons or those who have received no instruc-
tion or training.
f) Children must be instructed not to play with the tool.
g) Dust from material such as paint containing lead,
some wood species, minerals and metal may be harm-
ful. Contact with or inhalation of the dust may cause
allergic reactions and/or respiratory diseases to the
operator or bystanders. Certain kinds of dust are clas-
sified as carcinogenic such as oak and beech dust
especially in conjunction with additives for wood con-
ditioning (chromate, wood preservative). Material
containing asbestos must only be treated by spe-
cialists. Where the use of a dust extraction device
is possible 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 workplace is well ventilated. The use of a
dust mask of filter class P2 is recommended. Fol-
low national requirements for the materials you
want to work with.
5.2.2 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
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
and unplug the supply cord. This prevents inadver-
tent starting when the power returns.
d) 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.
5.2.3 Electrical safety
a) Before beginning work, check the working area
(e.g. with a metal detector) to ensure that no con-
cealed 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.
5.2.4 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.
5.2.5 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. Breath-
ing protection must be worn if no dust removal sys-
tem is used.
