are connected and properly used. Use of these
devices can reduce dust related hazards.
3.1.4 Power tool use and care
a) Do not force the power tool. Use the correct power
tool for your application. 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 and/or
the battery pack from the power tool before mak-
ing any adjustments, changing accessories, or
storing power tools. Such preventive safety mea-
sures reduce the risk of starting the power tool acci-
dentally.
d) Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the pow-
er 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 oper-
ation. 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 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.
3.1.5 Battery tool use and care
a) Ensure the switch is in the off position before insert-
ing battery pack. Inserting the battery pack into
power tools that have the switch on invites acci-
dents.
b) Recharge only with the charger specified by the
manufacturer. A charger that is suitable for one
type of battery pack may create a risk of fire when
used with another battery pack.
c) Use power tools only with specifically designated
battery packs. Use of any other battery packs may
create a risk of injury and fire.
d) When battery pack is not in use, keep it away from
other metal objects like paper clips, coins, keys,
nails, screws, or other small metal objects that
can make a connection from one terminal to anoth-
er. Shorting the battery terminals together may
cause burns or a fire.

e) Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact acci-
dentally occurs, flush with water. If liquid contacts
eyes, additionally seek medical help. Liquid eject-
ed from the battery may cause irritation or burns.
3.1.6 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 main-
tained.
3.2 Additional safety precautions
3.2.1 Personal safety
a)Breathing protection must be worn when the tool is
used without a dust removal system for work that
creates dust.
b) The tool is not intended for use by children, by debil-
itated persons or those who have received no instruc-
tion or training.
c) Children must be instructed not to play with the tool.
d) 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). Mate-
rial containing asbestos must only be treated by spe-
cialists. Where the use of a dust extraction device
is possible it shall be used. To achieve a high lev-
el of dust collection, use a suitable vacuum clean-
er 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.
3.2.2 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 connection end system and that
they are properly fitted and secured in the chuck.
c) Hold tool by insulated gripping surfaces when per-
forming 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.
3.2.3 Electrical safety
a) Before beginning work, check the working area (e.g.
with a metal detector) to ensure that no concealed
