Further Safety Instructions for All Operations
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.
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.
