Dremel 4000 Notice D'utilisation page 11

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.
SAFETY WARNINGS COMMON FOR
GRINDING, SANDING, WIRE BRUSHING,
POLISHING OR ABRASIVE CUTTING-
OFF OPERATIONS
a. This power tool is intended to function as a grinder, sander,
wire brush, polisher or cut-off tool. Read all safety warnings,
instructions, illustrations and specifications provided with
this power tool. Failure to follow all instructions listed below
may result in electric shock, fire and/or serious injury.
b. Do not use accessories which are not specifically designed
and recommended by the tool manufacturer. Just because
the accessory can be attached to your power tool, it does
not assure safe operation.
c. The rated speed of the accessory must be at least equal to
the maximum speed marked on the power tool. Accessories
running faster than their rated speed can fall apart.
d. The outside diameter and the thickness of your accessory
must be within the capacity rating of your power tool.
Incorrectly sized accessories cannot be adequately guarded
or controlled.
e. The arbour size of wheels, flanges, backing pads or any
other accessory must properly fit the spindle of the power
tool. Accessories with arbour holes that do not match the
mounting hardware of the power tool will run out of balance,
vibrate excessively and may cause loss of control.
f. Do not use a damaged accessory. Before each use inspect
accessories such as abrasive wheels for chips and cracks,
backing pads for cracks, tear or excess wear, and wire
brushes for loose or cracked wires. If the 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.
g. Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety glasses.
As appropriate, wear dust mask, hearing protectors, gloves
and shop 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.
h. Keep bystanders a safe distance away from work area.
Anyone entering the work area must wear personal
protective equipment. Fragments of the workpiece or of a
broken accessory may fly away and cause injury beyond the
immediate area of operation.
i. Hold the power tool only by the insulated gripping surfaces
when performing an operation where the cutting tool may
contact hidden wiring or its own power cord. Contact with a
"live" wire will also make exposed metal parts of the power
tool "live" and shock the operator.
j. 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.
k. 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.
l. 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.
m. 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.
n. Do not operate the power tool near flammable materials.
Sparks could ignite these materials.
o. Do not use accessories that require liquid coolants. Using
water or other liquid coolants may result in electrocution or
shock.
p. Do not use excessively oversized sanding disc paper. Follow
manufacturers recommendations, when selecting sanding
paper. Larger sanding paper extending beyond the sanding
pad presents a laceration hazard and may cause snagging,
tearing of the disc or kickback.
q. Do not allow any loose portion of the polishing bonnet or
its attachment strings to spin freely. Tuck away or trim any
loose attachment strings. Loose and spinning attachment
strings can entangle your fingers or snag on the workpiece.
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.
a. 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.
b. Never place your hand near the rotating accessory. Accessory
may kickback over your hand.
