Hilti TE 700-AVR Operating Instructions Manual page 25

The power tool is not intended for use by children,
f)
by debilitated persons or those who have received
no instruction or training.
g) 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
en
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.
5.3.2 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
22
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
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
residual current device) with a maximum tripping
current of 30 mA is recommended.
f) Switch the power tool off and unplug the supply
cord in the event of a power failure or interruption
in the electric supply. This will prevent accidental
restarting when the electric power returns.
5.3.3 Work area
a) Ensure that the workplace is well ventilated. Ex-
posure to dust at a poorly ventilated workplace may
result in damage to the health.
b) Keep the workplace tidy. Objects which could
cause injury should be removed from the work-
ing area. Untidiness at the workplace can lead to
accidents.
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) Approval must be obtained from the site engineer
or architect prior to beginning the work. Work
on buildings and other structures may influence
the statics of the structure, especially when steel
reinforcing bars or load-bearing components are
cut through.
5.3.4 Personal protective equipment
The user and any other persons in the vicinity must
wear suitable eye protection, a hard hat, ear protec-
tion, protective gloves, safety footwear and respirat-
ory protection while the tool is in use.
