KICKBACK
Kickback is a sudden reaction to a pinched,bound or misaligned saw blade,causing an uncontrolled
saw to lift up and out of the workpiece toward the operator.
1. When a blade is pinched or bound tightly by the kerf closing down, the blade stalls and the
motor reaction may drive the unit back toward the operator rapidly.
2. If the blade is twisted or misaligned in the cut, the teeth at the back edge of the blade can
dig into the top surface of the wood which may cause the blade to climb out of the kerf or
jump back toward the operator.
3. Using dull blades or improperly supported work will increase the tendency of kickback.
4. To prevent kickback, wet lumber, green lumber or pressure treated lumber all require.
SPECIAL ATTENTION DURING CUTTING OPERATIONS
Kickback is the result of saw misuse and/or incorrect operating procedures or conditions and can
be avoided by taking proper precautions as given below.
1. Maintain a firm grip with both hands on the saw and position your arms to resist kickback
forces.Position your body to either side of the blade,but not in line with the blade. Kickback
could cause the saw to jump backwards,but kickback force can be controlled by the
operator,if proper precautions are taken.
2. When a blade is binding,or when interrupting a cut for any reason,release the trigger and
hold the saw motionless in the material until the blade comes to a complete stop. Never
attempt to remove the saw from the work or pull the saw backward while the blade is in
motion or kickback may occur.Investigate and take corrective actions to eliminate the
cause of blade binding.
3. When restarting a saw in the workpiece,centre the saw blade in the kerf and check that
saw teeth are not engaged into the matieral.If saw blade is binding,it may walk up or
kickback from the workpiece as the saw is restarted.
4. Support large panels to minimise the risk of blade pinching and kickback.Large panels
tend to sag under their own weight.Support must be placed under the panel on both sides,
near the line of cut and near the edge of the panel.
5. Do not use dull or damaged blades.Unsharpened or improperly set blades produce narrow
kerf causing excessive friction,blade binding and kickback.
