Kickback And Related Warnings - DeWalt DCE800 Manual De Instrucciones

English
power tool. Accessories running faster than their
RATED SPEED can break and fly apart.
e ) 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.
f ) Threaded mounting of accessories must match
the grinder spindle thread. For accessories
mounted by flanges, the arbour hole of the
accessory must fit the locating diameter of the
flange. Accessories that do not match the mounting
hardware of the power tool will run out of balance,
vibrate excessively and may cause loss of control.
g ) Do not use a damaged accessory. Before each
use inspect the backing pad for cracks, tear
or excess wear. 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 ) 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.
k ) 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.
l ) 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.
m ) Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
n ) 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 a backing pad is snagged or pinched by the
workpiece, the edge of the pad 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.
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.
c ) Do not position your body in the area where
power tool will move if kickback occurs. Kickback
will propel the tool in direction opposite to the wheel's
movement at the point of snagging.
d ) 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.
e ) Do not attach a toothed saw blade. Such blades
create frequent kickback and loss of control.
Safety Warnings Specific for Sanding
Operations:
a ) Do not use excessively oversized sanding disc
paper. Follow manufacturer's 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.
