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.
5.1.5 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.
5.2 Additional safety instructions
5.2.1 Personal safety
a) 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.
b) Wear ear protectors. Exposure to noise can cause
hearing loss.
c) Keep the grips dry, clean and free from oil and
grease.
d) Improve the blood circulation in your fingers by
relaxing your hands and exercising your fingers
during breaks between working.
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)
Children must be instructed not to play with the
power tool.
g) The power tool is not intended for use by children,
by debilitated persons or those who have received
no instruction or training.
h) 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.
5.2.2 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) 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.
d) Do not grip or hold the rotating bit when the depth
gauge is removed.
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 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) 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.
d) 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 safety
a) Ensure that the workplace is well lit.
b) Ensure that the workplace is well ventilated. Ex-
posure to dust at a poorly ventilated workplace may
result in damage to the health.
