may be pulled into the spinning accesso-
ry.
- Never lay the power tool down until the
accessory has come to a complete stop.
The spinning accessory may grab the sur-
face and pull the power tool out of your
control.
- 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.
- 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.
- Do not operate the power tool near fl am-
mable materials. Sparks could ignite these
materials.
- Do not use accessories that require li-
quid coolants. Using water or other liquid
coolants may result in electrocution or
shock.
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 ro-
tating accessory which in turn causes the
uncontrolled power tool to be forced in the
direction opposite of the accessory’s rota-
tion 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 power tool misuse
and/or incorrect operating procedures or
conditions and can be avoided by taking
proper precautions listed below.
- Maintain a fi rm grip on the power tool and
position your body and arm to allow you
to resist kickback forces. Always use au-
xiliary 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.
- Never place your hand near the rotating
accessory. Accessory may kickback over
your hand.
- Do not position your body in the area whe-
re 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.
- 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.
- Do not attach a saw chain woodcarving
blade or toothed saw blade. Such blades
create frequent kickback and loss of con-
trol.
Safety Rules specifi c for Polishing ope-
rations
- Do not allow any loose portion of the po-
lishing bonnet or its attachment strings to
spin freely. Tuck away or trim any loose
attachment strings. Loose and spinning
attachment strings can entangle your
fi ngers or snag on the workpiece.
