Causes and Operator Prevention of Kickback:
31.
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.
When the blade is pinched or bound tightly by the kerf closing down, the blade
stalls and the motor reaction drives the unit rapidly back toward the operator.
If the blade becomes twisted or misaligned in the cut, the teeth at the back edge of
the blade can dig into the top surface of the wood causing the blade to climb out
of the kerf and jump back toward operator.
Kickback is the result of tool misuse and/or incorrect operating procedures or
conditions and can be avoided by taking proper precautions as given below:
32.
Maintain a firm grip with both hands on the saw and position your body and
arm to allow you to resist KICKBACK forces. KICKBACK forces can be
controlled by the operator, if proper precautions are taken.
33.
When 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.
Investi gate and take corrective actions to eliminate the cause of blade binding.
34.
When restarting a saw in the workpiece, center the saw blade in the kerf and
check that saw teeth are not engaged into the material. If saw blade is
binding, it may walk up or KICKBACK from the workpiece as the saw is restarted.
35.
Support large panels to minimize the risk of blade pinching and KICKBACK.
Large panels tend to sag under their own weight. Supports must be placed under
the panel on both sides, near the line of cut and near the edge of the panel.
36.
Do not use dull or damaged blade. Unsharpened or improperly set blades
produce narrow kerf causing excessive friction, blade binding and KICKBACK.
37.
Blade depth and bevel adjusting locking levers must be tight and secure
before making cut. If blade adjustment shifts while cutting, it may cause binding
and KICKBACK.
38.
Use extra caution when making a "Pocket Cut" into existing walls or other
blind areas. The protruding blade may cut objects that can cause KICKBACK.
