tool is maintained.
2. Additional safety precautions
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 extrac-
tion hose away tho the rear.
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 inadver-
tent starting when the power returns.
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 dam-
aged 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, especial-
ly if used frequently for working on
conductive materials.
Dust (especial-
ly dust from conductive materials) or
dampness adhering to the surface of
the tool may, under unfavorable condi-
tions, present a risk of electric shock.
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.
2.5 Personal protective equipment
The user and any other persons in the
vicinity must wear suitable eye protec-
tion, ear protection and protective gloves
when the tool is in use. Breathing protec-
tion must be worn if no dust removal
system is used.
