▶ Never use damaged or incorrect blade washers or bolt. The blade
washers and bolt were specially designed for your saw, for optimum
performance and safety of operation.
Kickback causes and related warnings
• kickback is a sudden reaction to a pinched, jammed 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 jammed 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 either 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 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, centre the saw blade in the
kerf so that the saw teeth are not engaged into the material. If a saw
blade binds, it may walk up or kickback from the workpiece as the saw
is restarted.
▶ Support large panels to minimise 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 friction, blade binding
and kickback.
▶ Blade depth and bevel adjusting locking levers must be tight and
secure before making the cut. If blade adjustment shifts while cutting,
it may cause binding and kickback.
▶ Use extra caution when sawing into existing walls or other blind
areas. The protruding blade may cut objects that can cause kickback.
