Additional Safety Precautions - Hilti WSC 85 Mode D'emploi

1.1.9 Additional safety instructions for
all saws with riving knife
a) Use the appropriate riving knife for the
blade being used. For the riving knife
to work, it must be thicker than the
body of the blade but thinner than the
tooth set of the blade.
b)Adjust the riving knife as described in
this instruction manual. Incorrect
spacing, positioning and alignment can
make the riving knife ineffective in
preventing kickback.
c) Always use the riving knife except
when plunge cutting. Riving knife
must be replaced after plunge cutting.
Riving knife causes interference
during plunge cutting and can create
kickback.
d)For the riving knife to work, it must be
engaged in the workpiece. The riving
knife is ineffective in preventing
kickback during short cuts.
e) Do not operate the saw if riving knife
is bent. Even a light interference can
slow the closing rate of a guard.

1.2 Additional safety precautions

1.2.1 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) Breathing protection must be worn
when the tool is 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 extraction
hose away tho the rear.

e) Bring the blade into contact with the
workpiece only after the circular saw
has been switched on.
f) The area above and below the kerf
must be free of obstructions. Do not
saw into screws and nails etc.
g)Do not use the machine for sawing
overhead.
h)Do not attempt to brake the speed of
the saw blade by pressing it to the
side.
i) Do not use:
– cutting discs designed for use with
an angle grinder
– hardened steel saw blades (HSS
steel)
j) Do not touch the part of the blade
projecting beneath the workpiece, the
clamping flange or the flange screw.
k) 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 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. Follow national
requirements for the materials you
want to work with.
l) The tool is not intended for use by
children, by debilitated persons or
those who have received no
instruction or training.
m) Children must be instructed not to
play with the tool.
1.2.2 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 con -
nection 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 inadvertent
starting when the power returns.
d) Hold tool by insulated gripping
surfaces when performing 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.
1.2.3 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
electrician 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) Use of a fault current protection
switch increases safety at work.
1.2.4 Work area
a) Ensure that the workplace is well lit.
b) Ensure that the workplace is well
ventilated. Poorly ventilated work -
places may be injurious to the health
due to exposeure to dust.
1.2.5 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. Breathing
protection must be worn if no dust
removal system is used.
