Kickback And Related Warnings - Stanley SP137 Manual

in accordance with these instructions, taking into
account the working conditions and the work to be
performed. Use of the power tool for operations different
from those intended could result in a hazardous situation.
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 INSTRUCTIONS FOR ALL OPERATIONS
Safety Warnings Common for Polishing
a. This power tool is intended to function as a polisher.
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. Operations such as grinding, sanding, wire
brushing or cutting-off are not recommended to
be performed with this power tool. Operations for
which the power tool was not designed may create a
hazard and cause personal injury.
c. 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.
d. 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 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 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.
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. 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.
k. 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.
l. 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.
m. 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.
n. 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.
o. Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
p. Do not use accessories that require liquid
coolants. Using water or other liquid coolants may
result in electrocution or shock.
FURTHER SAFETY INSTRUCTIONS FOR ALL
OPERATIONS

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 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 reaction or kickback forces, if proper precautions
are taken.
