Work Area Safety; Personal Protective Equipment - Hilti DCG 230-D Bedienungsanleitung

5.2.7 Power tool use and care
a) Grinding discs must be stored and handled care-
fully in accordance with the manufacturer's in-
structions.
b) Check that the grinding disc is fitted in accord-
ance with the manufacturer's instructions.
c) If use of a spacer ring or other intermediate part
is specified and the part is supplied with the
grinding disc, check to ensure that the part is
fitted.
d) Never use the power tool without the guard.
e) The workpiece must be fixed securely in place.
f) Before use, check that the cutting or grinding
disc has been fitted correctly and the clamping
nut tightened. Then allow the power tool to run
for 30 seconds under no load while holding it
securely. Switch off the power tool immediately
if significant vibration or any other faults are
noticed. Should this occur, examine the power
tool in order to determine the cause.
g) Do not use cutting discs for grinding.
h) Take steps to ensure that flying sparks from
the power tool do not present a hazard, i.e. by
striking yourself or other persons. Adjust the
position of the guard accordingly.
i) After disc breakage, or if the power tool is
dropped, falls or suffers other mechanical dam-
age, it must be checked at a Hilti Service Center.
5.2.8 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) Check the power tool's supply cord at regular
intervals and have it replaced by a qualified
specialist if found to be damaged. If the power
tool's supply cord is damaged it must be re-
placed with a specially-prepared supply cord
available from Hilti Customer Service. Check
extension cords at regular intervals and replace
them if found to be damaged. Do not touch the
supply cord or extension cord if it is damaged

while working. Disconnect the supply cord plug
from the power outlet. Damaged supply cords or
extension cords present a risk of electric shock.
c) Dirty or dusty power tools which have been
used frequently for work on conductive mater-
ials should be checked at regular intervals at
a Hilti Service Center. Under unfavorable cir-
cumstances, dampness or dust adhering to the
surface of the power tool, especially dust from
conductive materials, may present a risk of elec-
tric shock.
d) When working outdoors with an electric tool
check to ensure that the tool is connected to the
electric supply by way of a ground fault circuit
interrupter (RCD) with a rating of max. 30 mA
(tripping current). Use of a ground fault circuit
interrupter reduces the risk of electric shock.
e) Use of a ground fault circuit interrupter (RCD re-
sidual current device) with a maximum tripping
current of 30 mA is recommended.

5.2.9 Work area safety

a) Ensure that the workplace is well lit.
b) Ensure that the workplace is well ventilated.
Exposure to dust at a poorly ventilated workplace
may result in damage to the health.
c) If the work involves breaking right through, take
the appropriate safety measures at the opposite
side. Parts breaking away could fall out and / or
fall down and injure other persons.
d) Slits cut in loadbearing walls of buildings or other
structures may influence the statics of the struc-
ture, especially when steel reinforcing bars or
load-bearing components are cut through. Con-
sult the structural engineer, architect, or person
in charge of the building project before begin-
ning the work.

5.2.10 Personal protective equipment

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