Additional Safety Rules; Personal Protective Equipment - Hilti DD 130 Manual De Instrucciones

will ensure that the safety of the power tool is main-
tained.

5.2 Additional safety rules

5.2.1 Personal safety
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)The tool may be operated only when held in both
hands or when mounted on the drill stand. Ensure
that the side handle is fitted correctly and tight-
ened securely. Always hold the tool in both hands
when it is in use.
d)Breathing protection must be worn when the tool
is used without a dust removal system for work
that creates dust.
e)To avoid tripping and falling when working, always
lead the sypply cord, extension cord and dust
extraction hose away tho the rear.
f) Take care to avoid tripping over the supply cord,
extension cord or extraction hose.
g)Avoid skin contact with drilling slurry.
h)Ensure that the water swivel / extraction head (side
handle mount) is properly secured in position and
that the locking ring is tightened (see 6.1.3).
i) Ensure that the tool is securely attached when
mounted on the drill stand (see 6.9).
j) Do not touch rotating parts.
k)The tool is not intended for use by children, by
debilitated persons or those who have received
no instruction or training.
l) Children must be instructed not to play with the
tool.
m)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 allergic reactions and/or respiratory diseases
to the operator or bystanders. Certain kinds of dust
are classified as carcinogenic such as oak and beech
dust especially in conjunction with additives for
wood conditioning (chromate, wood preservative).
Material containing asbestos must only be treated
by specialists. 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 vacu-
um 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 rec-
ommended. Follow national requirements for the
materials you want to work with.
5.2.2 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 inad-
vertent starting when the power returns.
c)Observe the instructions concerning care and main-
tenance and the replacement of core bits in good
time.
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 elec-
tric 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 condi-
tion of the extension cord and replace it if dam-
age 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.
d)If a PRCD is supplied with the power tool, never
operate the power tool without the PRCD (GB ver-
sion: never operate the power tool without the iso-
lating transformer).
e)Ensure that the tool is switched off (remove the
switch lock insert) before switching on at the PRCD
(ground fault interrupter). Test the PRCD each time
before use (see 7.1).
5.2.4 Work area
a) Ensure that the workplace is well lit.
b) Ensure that the workplace is well ventilated. Poor-
ly 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 safety goggles, a safety helmet, ear pro-
tection, safety gloves and safety boots while the tool
is in operation.
