Kickback And Related Warnings - Würth EWS 18-A Manual De Instrucciones

❏ Treaded 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.
❏ Do not use a damaged accessory. Before
each use inspect the accessory such as
abrasive wheels for chips and cracks, back-
ing 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.
❏ Wear personal protective equipment.
Depending on application, use face shield,
safety goggles or safety glasses. As appro-
priate, wear dust mask, hearing protectors,
gloves and workshop apron capable of
stopping small abrasive or workpiece frag-
ments. The eye protection must be capable of
stopping flying debris generated by various oper-
ations. The dust mask or respirator must be capa-
ble of filtrating particles generated by your
operation. Prolonged exposure to high intensity
noise may cause hearing loss.
❏ 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.
❏ Hold power tool by insulated gripping sur-
faces 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 shock the operator.
❏ Position the cord clear of the spinning
accessory. If you lose control of the power tool,
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 hous-
ing and excessive accumulation of powdered
metal may cause electrical hazards.
❏ Do not operate the power tool near flam-
mable 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 direc-
tion of the wheel's movement at the point of pinch-
ing. 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 reac-
tions or kickback forces, if proper precautions are
taken.
❏ Never place your hand near the rotating
accessory. Accessory may kickback over your
hand.
