o)
The appliance is not intended for use by debilit-
ated persons who have received no special train-
ing. Keep the appliance out of reach of children.
p)
Adjust the pressure applied to the saw blade and
the material being cut so that the blade does not
stall, possibly causing the power tool to kick back.
q)
Avoid overheating the tips of the saw blade teeth.
r)
When cutting plastics, melting of the plastic
should be avoided.
s) Working on the material may cause it to splinter.
Wear eye protection and protective gloves. Wear
breathing protection if no dust removal system is
used.
Splintering material presents a risk of injury to
the eyes and body.
t)
Before beginning the work, check the hazard clas-
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 materials, such as paint containing lead,
some wood species, concrete / masonry / stone con-
taining silica, and minerals as well as metal, may be
harmful. Contact with or inhalation of the dust may
cause allergic reactions and/or respiratory or other
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 dust
extractor. When indicated wear a respirator ap-
propriate for the type of dust generated. Ensure
that the workplace is well ventilated. Follow na-
tional requirements for the materials you want to
work with.
v)
The cutting depth set should always be approx.
5 to 10 mm greater than the thickness of the
material to be cut.
2.3.2 Electrical safety
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.
2.3.3 Careful handling and use of batteries
a)
Observe the special guidelines applicable to the
transport, storage and use of Li-ion batteries.
b)
Do not expose batteries to high temperatures and
keep them away from fire.
This presents a risk of
explosion.
c)
Do not disassemble, squash or incinerate batter-
ies and do not subject them to temperatures over
80°C.
This presents a risk of fire, explosion or injury
through contact with caustic substances.
d)
Do not charge or continue to use damaged bat-
teries (e.g. batteries with cracks, broken parts,
bent or pushed-in and/or pulled-out contacts).
e) If the battery gets hot while not in use, the battery or
the power tool/battery system may be defective.
Put
the power tool/battery system in a suitable place
where it is an adequate distance from flammable
materials. Keep the system under observation
while it is cooling down and contact Hilti Service.
