Kickback And Related Warnings - Dremel 7020 Traduction De La Notice Originale

g. Do not use a damaged accessory. Before each use inspect the accessory
such as abrasive wheels for chips and cracks, sanding drum for cracks,
tear or excess wear, wire brush for loose or cracked wires. If power tool
or accessory is dropped, inspect for damage or install an undamaged
accessory. After inspecting and installing an accessory, position yourself
and bystanders away from the plane of the rotating accessory and run the
power tool at maximum no-load speed for one minute. Damaged accessories
will normally break apart during this test time.
h. Wear personal protective equipment. Depending on application, use face
shield, safety goggles or safety glasses. As appropriate, wear dust mask,
hearing protectors, gloves and workshop apron capable of stopping
small abrasive or workpiece fragments. The eye protection must be capable
of stopping flying debris generated by various operations. The dust mask or
respirator must be capable of filtrating particles generated by your operation.
Prolonged exposure to high intensity noise may cause hearing loss.
i. Keep bystanders a safe distance away from work area. Anyone entering the
work area must wear personal protective equipment. Fragments of workpiece
or of a broken accessory may fly away and cause injury beyond immediate area
of operation.
j. Hold power tool by insulated gripping surfaces only, when performing an
operation where the cutting accessory may contact hidden wiring. Cutting
accessory contacting a "live" wire may make exposed metal parts of the power
tool "live" and could give the operator an electric shock.
k. Always hold the tool firmly in your hand(s) during the start-up. The reaction
torque of the motor, as it accelerates to full speed, can cause the tool to twist.
l. Use clamps to support workpiece whenever practical. Never hold a small
workpiece in one hand and the tool in the other hand while in use. Clamping
a small workpiece allows you to use your hand(s) to control the tool. Round
material such as dowel rods, pipes or tubing have a tendency to roll while being
cut, and may cause the bit to bind or jump toward you.
m. 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.
n. After changing the bits or making any adjustments, make sure the collet
nut, chuck or any other adjustment devices are securely tightened. Loose
adjustment devices can unexpectedly shift, causing loss of control, loose rotating
components will be violently thrown.
o. 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.
p. 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.
q. Do not operate the power tool near flammable materials. Sparks could ignite
these materials.
r. 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, sanding band,
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.
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.
a. Maintain a firm grip on the power tool and position your body and arm to
allow you to resist kickback forces. The operator can control kickback forces,
if proper precautions are taken.
b. Use special care when working corners, sharp edges etc. Avoid bouncing
and snagging the accessory. Corners, sharp edges or bouncing have a
tendency to snag the rotating accessory and cause loss of control or kickback.
