c) Improve the blood circulation in your fingers by
relaxing your hands and exercising your fingers
during breaks between working.
d) Avoid touching rotating parts. Switch the power
tool on only after bringing it into position at the
workpiece. Touching rotating parts, especially rotat-
ing insert tools, may lead to injury.
e) Always lead the supply cord and extension cord
away from the power tool to the rear while work-
ing. This helps to avoid tripping over the cord while
working.
f) When grinding with straight grinding discs and
cutting with cutting discs in metalworking applic-
ations, use the guard with cover plate.
g) Children must be instructed not to play with the
power tool.
h) The power tool is not intended for use by children,
by debilitated persons or those who have received
no instruction or training.
i) Do not use the power tool if it starts with a jolt.This
may be an indication that the electronic control unit
is defective. Have the tool repaired at an authorized
Hilti service center right away.
j) 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 special-
ists. 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. Fol-
low national requirements for the materials you
want to work with.
5.6.2 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) Before use, check that the cutting disc has been
fitted correctly and the clamping nut tightened.
Then allow the power tool to run for 60 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.
e) Never use the power tool without the guard.
f) Do not use separate reducing rings or adapters to
enable use of grinding discs with a larger mount-
ing hole.
g) If the grinding disc (or cup wheel, etc.) is equipped
with a threaded insert, check that the threaded
section is long enough to take up the length of
the drive spindle.
h) The workpiece must be fixed securely in place.
i) Do not use cutting discs for grinding.
j) Take steps to ensure that flying sparks from the
tool do not present a hazard, i.e. by striking your-
self or other persons or by igniting inflammable
substances. Adjust the position of the disc guard
accordingly.
k) When working in dusty conditions, check to en-
sure that the cooling air openings remain unob-
structed. Should it become necessary to remove
dust deposits from the air openings, first unplug
the tool from the electric supply and then use a
non-metallic object to remove the dust, taking
care to avoid damaging parts inside the tool.
l) The disc continues to rotate after the power tool
has been switched off. Wait until the disc stops
rotating.
5.6.3 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
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 materials
should be checked at regular intervals at a Hilti
Service Center. Under unfavorable circumstances,
dampness or dust adhering to the surface of
the power tool, especially dust from conductive
materials, may present a risk of electric 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
