Kickback And Related Warnings - Black & Decker BPGP1518 Original Instruction

ENGLISH
accessory can be attached to your power tool,
it does not assure safe operation.
• 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 break
and fl y apart.
• 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.
• Threaded mounting of accessories must
match the grinder spindle thread. For
accessories mounted by fl anges, the
arbour hole of the accessory must fi t the
locating diameter of the fl ange. 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,
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 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 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 fl ying debris
generated by various operations. The dust
mask or respirator must be capable of fi ltering
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 fl y away and cause injury
beyond immediate area of operation.
• Hold power tool by insulated gripping
surfaces only, when performing an
operation where the cutting accessory
6
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.
• Use clamps or another practical way to
secure and support the workpiece to
a stable platform. Holding the work by hand
or against your body leaves it unstable and
may lead to loss of control.
• 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.
• 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 housing and excessive accumulation of
powdered metal may cause electrical hazards.
• Do not operate the power tool near
fl ammable 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 polisher pad 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 polisher pad 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.
