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 backing pad which in turn causes
uncontrolled power tool to be forced in the opposite
direction of the backing pad’s rotation at the point of the
binding.
For example, if an abrasive wheel is snagged or
pinched by the work piece, 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
incorrect operating procedures or conditions and can
be avoided by taking proper precautions as given
below.
1. Maintain a firm grip on the power tool and position
your body and arms to allow you to resist kickback
forces. Always use auxiliary handles, if provided
for maximum control over kickback or torque
reactions during start up. The operator can control
torque reactions or kickback forces, if proper
precautions are taken.
2. Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
3. Do not position your body in the area where power
tool will move if kickback occurs. Kickback will
propel the tool in the direction opposite to the
wheel’s movement at the point of the snagging.
4. 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.
Additional Rules For Safe Operation
1. Empty the dust bag or dust collection receiver
frequently. Do not leave residue in dust bag or dust
collection receiver unattended. Always empty in a
non-combustible metal container. Sanding wood
or varnish produces dust that can self ignite and
cause injury or damage. Follow this precaution for
storage.
2. Set all exposed nails. Sweep loose abrasive away
from work area. Do not strike metal pipes, etc.,
with sanding paper. Striking metal or abrasive
particles with sanding paper produces sparks that
could ignite the sanding dust which can cause
injury or damage.
3. Do not operate a partially assemble power tool.
Keep all adjustments within manufacturer’s
specifications. Keep all fasteners tight. Operating
a partially assembled power tool could result in
injury to the operator or bystander and could cause
damage to the equipment or surroundings.
4. Do not attempt to change the sanding paper while
the power tool is running. The sanding pad can
snag clothing and cause injury to limbs and moving
sanding paper can cause abrasions.
5. The power tool should only be used on an electrical
system (mains) that is rated for the electrical
requirements of the power tool as shown on the
nameplate. Use only on an earthing (grounded)
system. Do not service the power tool if it is
energized or connected to an electrical circuit.
Improper use could cause fire or electric shock.
