Kickback And Related Warnings - Skil 9455 Operating Instructions Manual

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) 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.
g) Do not use a damaged accessory. Before each use
inspect the accessory such as abrasive wheels for
chips and cracks, backing pads for cracks, tear or
excess wear, wire brushes for loose or cracked wires.
If the 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 4. 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.
i) Keep bystanders a safe distance away from work
area. Anyone entering the work area must wear
personal protective equipment. Fragments of the
workpiece or of a broken accessory may fly away and
cause injury beyond the immediate area of operation.
j) Hold the power tool only by the insulated gripping
surfaces when performing an operation where the
cutting tool may contact hidden wiring or its own
power cord. Contact with a "live" wire will also 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) D o 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.

2) 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 the 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.
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.
The 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 the 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 saw chain woodcarving blade or
toothed saw blade. Such blades create frequent
kickback and loss of control.
3) SAFETY WARNINGS SPECIFIC FOR GRINDING AND
CUTTING OFF OPERATIONS
a) Use only wheel types that are recommended for
your power tool and the specific guard designed
for the selected wheel. Wheels for which the power
tool was not designed cannot be adequately guarded
and are unsafe.
b) The guard must be securely attached to the power
tool and positioned for maximum safety, so the least
amount of wheel is exposed towards the operator.
The guard helps to protect the operator from broken
wheel fragments and accidental contact with the wheel.
c) Wheels must be used only for recommended
applications. For example: Do not grind with the side of
a cut-off wheel. Abrasive cut-off wheels are intended for
peripheral grinding; side forces applied to these wheels
may cause them to shatter.
d) Always use undamaged wheel flanges that are of
correct size and shape for your selected wheel.
Proper wheel flanges support the wheel thus reducing
the possibility of wheel breakage. Flanges for cut-off
wheels may be different from grinding wheel flanges.
