c) Disconnect the plug from the power source and/or the bat-
tery pack from the power tool before making any adjust-
ments, changing accessories, or storing power tools. Such
preventive safety measures reduce the risk of starting the pow-
er 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 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 cut-
ting 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 accor-
dance with these instructions, taking into account the work-
ing conditions and the work to be performed. Use of the pow-
er tool for operations different from those intended could result
in a hazardous situation.
4.1.5 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.

4.2 Additional safety precautions

4.2.1 Personal safety

a) Wear ear protectors. Exposure to noise can cause hear-
ing loss.
b) Use auxiliary handle(s), 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 sanding plate
may contact hidden wiring or its own cord. Sanding
plate contacting a "live" wire may make exposed metal
parts of the power tool "live" and could give the opera-
tor an electric shock.
d)Always hold the tool securely with both hands on
the grips provided. Keep the grips clean, dry and
free from oil and grease.
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) Wear protective gloves when changing insert tools.
The insert tool may become hot during use.
g)Operate the tool only as directed and only when it
is in faultless condition.
h)Use a dust extraction system and wear respirato-
ry protection and protective goggles. Sanding may
produce hazardous sanding dust. Sanding dust may
be harmful to the lungs and eyes.
i) The operator must ensure that hazardous sanding
dust is disposed of in accordance with national and
regional regulations. Hazardous sanding dust is
created when sanding materials such as oak or beech

wood, paint coatings containing lead or other harm-
ful substances.
j) Exercise your fingers during pauses between work
to improve the blood circulation in your fingers.
k) Dust from material such as paint containing lead,
some wood species, minerals and metal may be harm-
ful. 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 clas-
sified as carcinogenic such as oak and beech dust
especially in conjunction with additives for wood con-
ditioning (chromate, wood preservative). Material
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.
l) The tool is not intended for use by children, by debil-
itated persons or those who have received no instruc-
tion or training.
m) Children must be instructed not to play with the
tool.
4.2.2 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) In the event of a power faillure, switch the tool off
and unplug the supply cord. This prevents inad-
vertent starting when the power returns.

4.2.3 Electrical safety

a) Check the condition of the supply cord and its plug
connections and have it replaced by a qualified
electrician if damage is found. Check the condi-
tion of the extension cord and replace it if dam-
age is found.
Do not touch the supply in the event of it suffering
damage while working. Disconnect the supply cord
plug from the socket . Damaged supply cords and
extension cords present a risk of electric shock.
b) Dirty or dusty electric tools should thus be checked
at a Hilti service center at regular intervals, espe-
cially if used frequently for working on conductive
materials. Dust (especially dust from conductive
materials) or dampness adhering to the surface of
the tool may, under unfavorable conditions, pre-
sent a risk of electric shock.

4.2.4 Work area

a) Ensure that the workplace is well lit.
b) Ensure that the workplace is well ventilated.
Poorly ventilated workplaces may be injurious to
the health due to exposeure to dust.
