Hilti TE 800 Operating Instructions Manual page 7

d) Store idle power tools out of the reach of chil-
dren and do not allow persons unfamiliar with the
power tool or these instructions to operate the
power tool. Power tools are dangerous in the hands
of untrained users.
e) Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and
any other condition that may affect the power
tool's operation. If damaged, have the power tool
repaired before use. Many accidents are caused by
poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly main-
tained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc.
in accordance with these instructions, taking into
account the working conditions and the work to
be performed. Use of the power tool for opera-
tions different from those intended could result in a
hazardous situation.
2.1.5 Service
a) Have your power tool serviced by a qualified repair
person using only identical replacement parts.
This will ensure that the safety of the power tool is
maintained.
2.2 Hammer safety warnings
a) Wear ear protectors. Exposure to noise can cause
hearing loss.
b) Use auxiliary handles, if supplied with the tool.
Loss of control can cause personal injury.
c) Hold power tool by insulated gripping surfaces,
when performing an operation where the cutting
accessory may contact hidden wiring or its own
cord. Cutting accessory contacting a "live" wire may
make exposed metal parts of the power tool "live"
and could give the operator an electric shock.
2.3 Additional safety instructions
2.3.1 Personal safety
a) Modification of the machine or tampering with its
parts is not permissible.
b) Store power tools, when not in use, in a secure
place. When not in use, power tools must be
stored in a dry, high place or locked away out of
reach of children.
c) Improve the blood circulation in your fingers by
relaxing your hands and exercising your fingers
during breaks between working.
d) 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.
e) The appliance is not intended for use by debilit-
ated persons who have received no special train-
ing. Keep the appliance out of reach of children.
f) Dust from materials, such as paint containing lead,
some wood species, concrete / masonry / stone con-
taining silica, and minerals as well as metal, may be
harmful. Contact with or inhalation of the dust may
cause allergic reactions and/or respiratory or other
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 dust
extractor. When indicated wear a respirator ap-
propriate for the type of dust generated. Ensure
that the workplace is well ventilated. Follow na-
tional requirements for the materials you want to
work with.
2.3.2 Electrical safety
a) Concealed electric cables or gas and water pipes
present a serious hazard if damaged while you
are working. Accordingly, check the area in which
you are working beforehand (e.g. using a metal
detector). External metal parts of the power tool or
machine may become live, for example, when an
electric cable is damaged accidentally.
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 machine's
supply cord is damaged it must be replaced with
a specially-prepared and approved supply cord
available from Hilti Customer Service. 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 mains plug from
the power outlet. Damaged supply cords or exten-
sion 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) Hold power tool by insulated gripping surfaces
when performing an operation where the fastener
may contact hidden wiring or its own cord. Fasten-
ers contacting a "live" wire may make exposed metal
parts of the power tool "live" and could give the
operator an electric shock.
e) 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.
2.3.3 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-
