Safety Warnings Specific For Wire Brushing Operations; Additional Safety Instructions - Hilti AG 500-A18 Mode D'emploi

of operation, is moving away from your body, the
possible kickback may propel the spinning wheel
and the power tool directly at you.
c) When wheel is binding or when interrupting a cut
for any reason, switch off the power tool and hold
the power tool motionless until the wheel comes
to a complete stop. Never attempt to remove the
cut-off wheel from the cut while the wheel is in
motion otherwise kickback may occur.Investigate
and take corrective action to eliminate the cause of
wheel binding.
d) Do not restart the cutting operation in the work-
piece. Let the wheel reach full speed and carefully
re-enter the cut. The wheel may bind, walk up or
kickback if the power tool is restarted in the work-
piece.
e) Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kickback.
Large workpieces tend to sag under their own weight.
Supports must be placed under the workpiece near
the line of cut and near the edge of the workpiece on
both sides of the wheel.
f) Use extra caution when making a "pocket cut"
into existing walls or other blind areas. The pro-
truding wheel may cut gas or water pipes, electrical
wiring or objects that can cause kickback.
2.6 Safety warnings specific for wire brushing
operations
a) Be aware that wire bristles are thrown by the
brush even during ordinary operation. Do not
overstress the wires by applying excessive load
to the brush. The wire bristles can easily penetrate
light clothing and/or skin.
b) If the use of a guard is recommended for wire
brushing, do not allow any interference of the
wire wheel or brush with the guard. Wire wheel or
brush may expand in diameter due to work load and
centrifugal forces.

2.7 Additional safety instructions

2.7.1 Personal safety
a) Modification of the machine or tampering with its
parts is not permissible.
b) Wear ear protectors. Exposure to noise can cause
hearing loss.
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) Breathing protection must be worn if the power
tool is used without a dust removal system for
work that creates dust.
e) Improve the blood circulation in your fingers by
relaxing your hands and exercising your fingers
during breaks between working.
f) Avoid touching rotating parts. Switch the power
tool on only after bringing it into position at the
workpiece. Touching rotating parts, especially rotat-
ing insert tools, may lead to injury.
g) The appliance is not intended for use by debili-
tated persons who have received no special train-
ing. Keep the appliance out of reach of children.
h) Dust from materials, such as paint containing lead,
some wood species, concrete / masonry / stone con-
taining silica, and minerals as well as metal, may be
harmful. Contact with or inhalation of the dust may
cause allergic reactions and/or respiratory or other
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 de-
vice is possible it shall be used. To achieve a
high level of dust collection, use a suitable dust
extractor. When indicated wear a respirator ap-
propriate for the type of dust generated. Ensure
that the workplace is well ventilated. Follow na-
tional requirements for the materials you want to
work with.
i) The user and any other persons in the vicinity
must wear suitable eye protection, a hard hat,
ear protection, protective gloves and breathing
protection while the tool is in use.
j) If the electric tool detects that it is being operated
beyond its limits or if the battery is fully discharged,
it may happen that the disc is no longer braked by
the motor.
2.7.2 Power tool use and care
a) Grinding discs must be stored and handled care-
fully in accordance with the manufacturer's in-
structions.
b) Never use the power tool without the guard.
c) 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.
d) Do not use cutting discs for grinding.
e) Tighten the disc and flange securely. If the nut
securing the disc and flange is not tightened firmly,
the disc may work loose from the spindle due to
the braking effect of the power tool's motor after
switching off.
2.7.3 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) Dirty or dusty power tools that have been used fre-
quently for work on conductive materials should
be checked at regular intervals at a Hilti Service
Center. Under unfavorable circumstances, damp-
ness or dust adhering to the surface of the tool,
