cessories, or storing power tools. Such prevent-
ive safety measures reduce the risk of starting the
power tool accidentally.
d) Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the
power tool or these instructions to operate the
power tool. Power tools are dangerous in the
en
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
maintained 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 operations
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) Wear ear protectors. Exposure to noise can cause
hearing loss.
b) Use auxiliary handles supplied with the tool.
Loss of control can cause personal injury.
c) Always hold the power tool securely with both
hands on the grips provided. Keep the grips dry,
clean and free from oil and grease.
d) Hold tool by insulated gripping surfaces when
performing an operation where the cutting tool
may contact hidden wiring or its own cord. Con-
tact with a "live" wire will make exposed metal
parts of the tool "live" and shock the operator.
e) Breathing protection must be worn if the power
tool is used without a dust removal system for
work that creates dust.
f) Improve the blood circulation in your fingers by
relaxing your hands and exercising your fingers
during breaks between working.

g) Avoid touching rotating parts. Switch the power
tool on only after bringing it into position at
the workpiece. Touching rotating parts, especially
rotating insert tools, may lead to injury.
h) Always lead the supply cord and extension cord
away from the power tool to the rear while
working. This helps to avoid tripping over the cord
while working.
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
received no instruction or training.
l) 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.
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.
