SAFETY INSTRUCTIONS FOR
ALL OPERATIONS
SAFETY WARNINGS COMMON FOR GRINDING,
SANDING, WIRE BRUSHING, POLISHING, CARVING OR
ABRASIVE CUTTING-OFF OPERATIONS
Failure
to follow all instructions listed below may result in electric
shock, re and/or serious injury.
Just because the accessory can be attached to your power
tool, it does not assure safe operation.
Grinding accessories running faster than their
rated speed can break and y apart.
Incorrectly sized accessories cannot be
adequately controlled.
Accessories that do not match the mounting
hardware of the power tool will run out of balance, vibrate
excessively and may cause loss of control.
If the mandrel is insufciently held and/or the
overhang of the wheel is too long, the mounted wheel may
become loose and be ejected at high velocity.
Damaged accessories will normally
break apart during this test time.
The eye protection must be capable of stopping ying
debris generated by various operations. The dust mask or
respirator must be capable of ltrating particles generated
by your operation. Prolonged exposure to high intensity
noise may cause hearing loss.
Fragments of workpiece or of a
broken accessory may y away and cause injury beyond
immediate area of operation.
Cutting accessory contacting a “live” wire may make
exposed metal parts of the power tool “live” and could give
the operator an electric shock.
The reaction torque of the motor, as it accelerates
to full speed, can cause the tool to twist.
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.
If you
lose control, the cord may be cut or snagged and your hand
or arm may be pulled into the spinning accessory.
The spinning accessory may
grab the surface and pull the power tool out of your control.
Loose adjustment devices
can unexpectedly shift, causing loss of control, loose
rotating components will be violently thrown.
Accidental contact with the spinning accessory could snag
your clothing, pulling the accessory into your body.
The motor’s
fan will draw the dust inside the housing and excessive
accumulation of powdered metal may cause electrical
hazards.
Sparks could ignite these materials.
Using water or other liquid coolants may result in
electrocution or shock.
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.
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.
The operator can control kickback forces, if proper
precautions are taken.
Corners, sharp edges or bouncing have a tendency to
snag the rotating accessory and cause loss of control or
kickback.
Such blades create
frequent kickback and loss of control.
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.
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 le, 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
Abrasive cut-off wheels are intended for peripheral grinding,
