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.
c)
Do not position your body in the area where power tool
will move if kickback occurs.
Kickback will propel the tool
in 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.
Safety Warnings Specific for Polishing
Operations
a)
Do not allow any loose portion of the polishing bonnet
or its attachment strings to spin freely. Tuck away or
trim any loose attachment strings.
Loose and spinning
attachment strings can entangle your fingers or snag on the
workpiece.
Additional Specific Safety Instructions for
Polishers
• Always use eye protection.
All users and bystanders must wear
eye protection that conforms to ANSI Z87.1.
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.

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:
