wrench or a key left attached to a
rotating part of the power tool may
result in personal injury.
e) Do not overreach. Keep proper foot-
ing and balance at all times. This
enables better control of the power
tool in unexpected situations.
f) Dress properly. Do not wear loose
clothing or jewellery. Keep your hair,
clothing and gloves away from mov-
ing parts. Loose clothes, jewellery or
long hair can be caught in moving
parts.
g) If devices are provided for the con-
nection of dust extraction and collec-
tion facilities, ensure these are con-
nected and properly used. Use of
these devices can reduce dust related
hazards.
1.4 Power tool use and care
a) Do not force the power tool. Use the
correct power tool for your applica-
tion. The correct power tool will do
the job better and safer at the rate for
which it was designed.
b) Do not use the power tool if the
switch does not turn it on and off.
Any power tool that cannot be con-
trolled with the switch is dangerous
and must be repaired.
c) Disconnect the plug from the power
source before making any adjust-
ments, changing accessories, or
storing power tools. Such preventive
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 dan-
gerous in the hands of untrained
users.
e) Maintain power tools. Check for mis-
alignment 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 and in the manner
intended for the particular type of
power tool, 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.
1.5 Service
a) Have your power tool serviced by a
qualified repair person using only
genuine replacement parts. This will
ensure that the safety of the power
tool is maintained.
2. Additional safety rules
2.1 Personal safety
a) Wear ear protection. Excessive noise
may lead to a loss of hearing.
b) Use the auxiliary handle supplied
with the tool. Loss of control of the
tool may lead to injury.
c)Ensure that the side handle is fitted
correctly and tightened securely.
Always hold the tool in both hands
when it is in use.
d) Breathing protection must be worn
when the tool is used without a dust
removal system for work that creates
dust.
e) To avoid tripping and falling when
working, always lead the sypply
cord, extension cord and dust extrac-
tion hose away tho the rear.
f) Dust from material such as paint con-
taining lead, some wood species, min-
erals 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 conjunc-
tion with additives for wood condition-
ing (chromate, wood preservative).
Material containing asbestos must only
be treated by specialists. Where the
use of a dust extraction device is pos-
sible 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.
g) The tool is not intended for use by
children, by debilitated persons or
those who have received no instruc-
tion or training.
h) Children must be instructed not to
play with the tool.
2.2 Power tool use and care
a) Secure the workpiece. Use clamps
or a vice to hold the workpiece in
place. The workpiece is thus held
more securely than by hand and
both hands remain free to operate
the tool.
b) Ensure that the insert tools used are
equipped with the appropriate con-
nection end system and that they are
properly fitted and secured in the
chuck.
c) In the event of a power faillure,
switch the tool off and unplug the
supply cord. This prevents inadver-
tent starting when the power returns.
d) Hold tool by insulated gripping sur-
faces when performing an operation
where the cutting tool may contact
hidden wiring or its own cord.
Contact with a "live" wire will make
exposed metal parts of the tool "live"
and shock the operator.
2.3 Electrical safety
a) Before beginning work, check the
working area (e.g. with a metal
detector) to ensure that no con-
cealed electric cables or gas and
water pipes are present. External
metal parts of the tool may become
live if, for example, an electric cable is
damaged inadvertenly. This presents
a serious risk of electric shock.
