CAUSES AND OPERATOR PREVENTION OF 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.
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 the operator.
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:
Maintain a firm grip with both hands on the saw and position your arms to resist
kickback forces. Position your body to the left or right side of the blade, but
not in line with the blade. Kickback could cause the saw to jump backwards, but
kickback forces can be controlled by the operator, if proper precautions are taken.
When the 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.
When restarting a saw in the workpiece, cen
ter the saw blade in the kerf and
check that saw teeth are not engaged into the material. If the saw blades are
binding, it may walk up or kickback from the workpiece as the saw is restarted.
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.
Do not use dull or damaged blades. Unsharpened or improperly set blades
produce narrow kerf causing excessive frictio
n, blade binding and kickback.
Use extra caution when making a “plunge cut” into existing walls or other blind
areas. The protruding blade may cut objects that can cause kickback.
Check the lower guard for proper closing before each use. Do not operate the
saw if the lower guard does not move freely and close instantly. Never clamp
or tie the lower guard into the open position. If the saw is accidentally dropped,
the lower guard may be damaged. Raise the lower guard with the retracting handle
and make sure it moves fre
ely and does not touch the blade or any other part in all
depths of cuts.
Check the operation of the lower guard spring. If the guard and the spring are
not operating properly, they must be serviced before use. The lower guard may
operate sluggishly due to damaged parts, gummy deposits, or a build-up of debris.
The lower guard should be retracted manually only for special cuts such as
“plunge cuts” and “compound cuts”. Raise lower guard by retracting handle and
as soon as the blade enters the material, the lower guard must be released. For all
other sawing, the lower guard should operate automatically.
