Hilti AG 500-7SE Mode D'emploi page 14

Fragments of workpiece or of a broken accessory may fly away and
cause injury beyond immediate area of operation.
▶ Hold the power tool by insulated gripping surfaces only, when
performing an operation where the cutting accessory may contact
hidden wiring or its own cord. Cutting accessory contacting a "live"
wire may make exposed metal parts of the power tool "live" and could
give the operator an electric shock.
▶ Position the cord clear of the spinning accessory. If you lose control,
the cord may be cut or snagged and your hand or arm may be pulled into
the spinning accessory.
▶ Never lay the power tool down until the accessory has come to a
complete stop. The spinning accessory may grab the surface and pull
the power tool out of your control.
▶ Do not run the power tool while carrying it at your side. Accidental
contact with the spinning accessory could snag your clothing, pulling the
accessory into your body.
▶ Regularly clean the power tool's air vents. The motor's fan will draw the
dust inside the housing and excessive accumulation of powdered metal
may cause electrical hazards.
▶ Do not operate the power tool near flammable materials. Sparks could
ignite these materials.
▶ Do not use accessories that require liquid coolants. Using water or
other liquid coolants may result in electrocution or shock.
Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged rotating wheel,
backing pad, brush or any other accessory. Pinching or snagging causes
rapid stalling of the rotating accessory which in turn causes the uncontrolled
power tool to be forced in the direction opposite of the accessory's rotation
at the point of the binding.
For example, if an abrasive wheel is snagged or pinched by the workpiece,
the edge of the wheel that is entering into the pinch point can dig into the
surface of the material causing the wheel to climb out or kick out. The wheel
may either jump toward or away from the operator, depending on direction
of the wheel's movement at the point of pinching. Abrasive wheels may also
break under these conditions.
Kickback is the result of power tool misuse and/or incorrect operating
procedures or conditions and can be avoided by taking proper precautions
as given below.
▶ Maintain a firm grip on the power tool and position your body and arm
to allow you to resist kickback forces. Always use auxiliary handle,
if provided, for maximum control over kickback or torque reaction
during start-up. The operator can control torque reactions or kickback
forces, if proper precautions are taken.
