5.7 Additional safety instructions

5.7.1 Personal safety
a) Always hold the power tool securely with both
hands on the grips provided. Keep the grips dry,
clean and free from oil and grease.
b) Breathing protection must be worn if the power
tool is used without a dust removal system for
en
work that creates dust.
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 only the guard with cover plate. This is
available as an optional accessory.
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-

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

in order to determine the cause.
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
dropped, falls or suffers other mechanical
damage, it must be checked at a Hilti Service
Center.
(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.
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.
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.
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.
