Work Area; Personal Protective Equipment; Protective Devices; Operation - Hilti WSC 70 Manual De Instrucciones

p) The power tool is not intended for use by children,
by debilitated persons or those who have received
no instruction or training.
q) Adjust the pressure applied to the saw blade and
the material being cut so that the blade doesn't
stall, possibly causing the power tool to kick back.
r) Avoid overheating the tips of the saw blade teeth.
s) When cutting plastics, melting of the plastic
should be avoided.
Before beginning the work, check the hazard clas-
t)
sification of the dust that will be produced. Use
an industrial vacuum cleaner with an officially
approved protection classification in compliance
with locally applicable dust protection regula-
tions.
u) 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 special-
ists. 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.
5.6.2 Power tool use and care
a) Hold power tool by insulated gripping surfaces
when performing an operation where the fastener
may contact hidden wiring or its own cord. Fasten-
ers contacting a "live" wire may make exposed metal
parts of the power tool "live" and could give the
operator an electric shock.
b) 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.

6 Operation

CAUTION
Wear protective gloves. The cutting edges of the saw
blade teeth are sharp. The cutting edges may present a
risk of injury.
c) Check that the insert tools used are compatible
with the chuck system and that they are secured
in the chuck correctly.
5.6.3 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) Always lead the supply cord and extension cord
away from the power tool to the rear while work-
ing. This helps to avoid tripping over the cord while
working.

5.6.4 Work area

a) Ensure that the workplace is well lit.
b) Ensure that the workplace is well ventilated. Ex-
posure to dust at a poorly ventilated workplace may
result in damage to the health.

5.6.5 Personal protective equipment

The user and any other persons in the vicinity must
wear suitable eye protection, a hard hat, ear protec-
tion, protective gloves and breathing protection while
the tool is in use.

5.6.6 Protective devices

Do not switch the power tool on if the saw blade, the
blade guard, the pivoting guard or the riving knife are
not fitted correctly.
CAUTION
Wear protective glasses and a dust mask. The sawing
operation swirls up dust and wood chips into the air. The
dust and wood chips may be harmful to the eyes and
respiratory system.
