extension cords present a risk of elec-
tric shock.
c)
Dirty or dusty electric tools should
thus be checked at a Hilti service cen-
ter at regular intervals, especially if
used frequently for working on con-
ductive materials.
Dust (especially
dust from conductive materials) or
dampness adhering to the surface of
the tool may, under unfavorable con-
ditions, 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 ven-
tilated.
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 pro-
tection must be worn if no dust removal
system is used.
ing, always lead the sypply cord, ex-
tension cord and dust extraction 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 se-
curely than by hand and both hands re-
main 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.
2.3 Electrical safety
a)
Before beginning work, check the work-
ing area (e.g. with a metal detector)
to ensure that no concealed electric
cables or gas and water pipes are pre-
sent.
External metal parts of the tool
may become live if, for example, an
electric cable is damaged inadverten-
ly. 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 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.

the socket
