Safety Instructions For All Operations; Kickback And Related Warnings - Dremel 300 Serie Instrucciones De Funcionamiento Y Seguridad

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.
SAFETY WARNINGS THAT ARE COMMON
FOR GRINDING, SANDING, WIRE BRUSHING,
POLISHING AND 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 fly 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
the accessory such as abrasive wheels for chips and
cracks, backing pad 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.
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.

SAFETY INSTRUCTIONS FOR ALL OPERATIONS

h. 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.
i. Hold 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 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.

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.
