Kickback
Kickback is the sudden and strong movement the tool
experiences outwards from the work piece that can lead
the operator to lose control or even cause him injuries.
Usually this happens when the cutting disc is stuck into
the piece or due to an inefficient operation. To avoid
kickback the following caution measures should be used:
• When the cut-off wheel gets jammed or caught in the
workpiece by the saw cut, the cut-off wheel stops and
consequently the reaction of the motor quickly directs the
tool towards the operator.
• Use perfectly maintained cutting discs. Double-check
discs are properly mounted. Badly mounted, bent,
damaged discs or with worn or dull teeth have a tendency
to get stuck into the material causing kickback.
• Maintain a firm grip on the tool, keeping your body and
arms so that you can resist kickback forces.
• Kickback can cause the saw to jump backward, but
kickback forces can be controlled by the operator if proper
precautions are taken.
• When operating the tool, hold it firmly setting one hand
on the handle and the other hand on the auxiliary handle.
Always use both hands. Keep good balance and footing to
be able to resist the force of possible kickback.
• To make cuts align the disc with the cut axle and wait for
the disc to reach its highest speed before starting to cut.
Do not try to cut setting the disc teeth on top of the work
piece. It could cause kickback.
• To restart working inside the cut, center the disc into the
cut and double-check the discs are not buried into the
material.
• If the cut-off wheel jams, it may advance upward or
produce kickback while restarting the saw operation.
• Support long workpieces to minimize the risk of binding
and kickback.
• If while operating the tool you notice the disc is bending
or the cut is interrupted, release the switch and hold the
tool inside the work piece until the disc comes to a
complete stop. Do not try to remove the disc while still
moving. This could cause kickback.
• To minimize the risk of having the disc stuck and cause
kickback, before cutting a wood piece remove all the nails.
Damp, warped wood or chipboard needs special attention
during the cut. When using large wood planks use supports
close to both sides of the cutting line to avoid the plank to
warp, close the cut and trap the disc. Wood resin and gum
hardened on the disc make the saw run slow. Use resin and
gum remover, hot water or kerosene to remove buildup.
DO NOT use gasoline.
• Use extreme care when making a pocket cut on wall or
blind spots. The disc may get into contact with hidden
objects and cause kickback.
• While operating the tool, do not set your hand or body
aligned with the cut axis, because if kickback sets there is a
severe injury hazard.
• Before starting a cut, the levers to adjust cutting depth
and bevel should be tight and secured. If they move
during the cut, they may cause the disc to bend and
cause kickback. Setting excessive cutting depth increases
the load on the unit and the disc might bend inside the
cut. It also increases the possibility that the cut closes and
increases the available area on top of the cutting disc.
• Do not use dull or damaged cut-off wheels.
• Dull or improperly installed cut-off wheels result in a
narrow cutting gap that causes excessive friction,
deformation of the cut-off wheels and kickback.
General measures
• Move away your hands from the
cutting area and the cutting disc. To prevent from
accidental injury and loosing control, firmly hold the tool
with both hands by the handle and the auxiliary handle.
Do not put your hand under the workpiece. The guard
cannot protect the operator if the cutting wheel reaches
the bottom of the workpiece.
• The accidental contact with a
rotating cutting disc may cause severe personal injury.
• NEVER hold the work piece to cut with
your hands or on top of your leg. Hold the work piece
adequately to avoid your body making contact with the
cutting disc, and to prevent the disc from bending or
loosing control of the tool or the work piece.
• Do not try to remove debris material
when the disc is running.
• Remember that the guards do not
protect you from the moving disc below the work piece.
Therefore never squat or try to put your hand below the
work piece when the machine is running.
