5.7.2 Power tool use and care
en
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 se-
curely. Switch off the power tool immediately if
significant vibration or any other faults are no-
ticed. 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.
After disc breakage, or if the power tool is
i)
dropped, falls or suffers other mechanical
damage, it must be checked at a Hilti Service
Center.
5.7.3 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 spe-
cialist if found to be damaged. If the power tool's
supply cord is damaged it must be replaced with
a specially-prepared supply cord available from
