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.
Maintain a firm grip on the power tool and position
your body and arm to allow you to resist kickback
forces.
The operator can control torque reactions or
kickback forces, if proper precautions are taken.
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 toothed saw blade.
Such blades create
frequent kickback and loss of control.
Always feed the bit into the material in the same
direction as the cutting edge is exiting from the
material (which is the same direction as the chips are
thrown).
Feeding the tool in the wrong direction causes
the cutting edge of the bit to climb out of the work and
pull the tool in the direction of this feed.
When using rotary files, cut-off wheels, high-speed
cutters or tungsten carbide cutters, always have the
work securely clamped.
These wheels will grab if they
become slightly canted in the groove, and can kickback.
When a cut-off wheel grabs, the wheel itself usually
breaks. When a rotary file, high-speed cutter or tungsten
carbide cutter grabs, it may jump from the groove and
you could lose control of the tool.
SAFETY WARNINGS SPECIFIC FOR
GRINDING AND ABRASIVE CUTTING-OFF
OPERATIONS:
Use only wheel types that are recommended for your
power tool and 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.
For threaded abrasive cones and plugs use only
undamaged wheel mandrels with an unrelieved
shoulder flange that are of correct size and length.
Proper mandrels will reduce the possibility of breakage.
Do not “jam” a cut-off wheel or apply excessive
pressure. Do not attempt to make an excessive depth
of cut.
Overstressing the wheel increases the loading and
susceptibility to twisting or snagging of the wheel in the
cut and the possibility of kickback or wheel breakage.
Do not position your hand in line with and behind the
rotating wheel.
When the wheel, at the point of operation,
is moving away from your hand, the possible kickback
may propel the spinning wheel and the power tool directly
at you.
Use clamps to support workpiece whenever practical.
Never hold a small workpiece in one hand and the
tool in the other hand while in use.
Clamping a small
workpiece allows you to use your hand(s) to control the
tool. Round material such as dowel rods, pipes or tubing
have a tendency to roll while being cut, and may cause
the bit to bind or jump toward you.
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.
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.
After changing the bits or making any adjustments,
make sure the collet nut, chuck or any other
adjustment devices are securely tightened.
Loose
adjustment devices can unexpectedly shift, causing loss
of control, loose rotating components will be violently
thrown.
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 flammable
materials.
Sparks could ignite these materials.
Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in
electrocution or shock.
The maximum recommended diameter of mounted
wheels, threaded cones and plugs shall not exceed
2 in. (55 mm) and that the maximum recommended
diameter of sanding accessories shall not exceed 3
in. (80 mm).
KICKBACK AND RELATED WARNINGS
Kickback is a sudden reaction to a pinched or snagged rotating
wheel, sanding band, 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.
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.
