Hilti TE 70 Operating Instructions Manual page 11

i) When using the power tool for mixing, set the
function selector switch to "Hammer drilling"
and wear protective gloves.
j) Children must be instructed not to play with the
appliance.
k) The appliance is not intended for use by chil-
dren, by debilitated persons or those who have
en
received no instruction or training.
5.2.2 Power tool use and care
a) Secure the workpiece. Use clamps or a vice
to secure the workpiece. The workpiece is thus
held more securely than by hand and both hands
remain free to operate the power tool.
b) Check that the insert tools used are compatible
with the chuck system and that they are secured
in the chuck correctly.
c) Always work from a secure, safe stance.
5.2.3 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
specialist if found to be damaged. Check ex-
tension 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 materi-
als should be checked at regular intervals at a
Hilti Service Center. Under unfavorable circum-
stances, 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
24
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.
5.2.4 Work area
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) 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 specialists. 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.
Follow national requirements for the materials
you want to work with.
d) 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.
5.2.5 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.
