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.
h)
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.
i)
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.
j)
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.
k)
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.
l)
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.
m)
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.
n)
Do not operate the power tool near flammable materials.
Sparks could ignite these materials.
o)
Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in electrocution
or shock.
p)
Do not use Type 11 (flaring cup) wheels on this tool.
Using
inappropriate accessories can result in injury.
q)
Always use side handle.
Tighten the handle securely.
The
side handle should always be used to maintain control of the
tool at all times.
Causes and Operator Prevention
of Kickback
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.
b)
Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
