• The rip fence is used to position workpiece for lengthwise cuts and narrow fence is used for extension table for large
workpiece cuts.
• It’s very important to use the blade guard assembly for all through-cut sawing operations. The blade guard assembly
includes: riving knife, anti-kickback pawls, and blade guard.
Causes of kickback
Kickback can occur when the blade stalls or binds, causing the workpiece to be kicked back toward the operator with
great force and speed. If your hands are near the saw blade, they may be jerked loose from the workpiece and come into
contact with the blade. Obviously, kickback can cause serious injury, and it is well worth using precautions to avoid the
risks. Kickback can be caused by any action that pinches the blade in the wood, such as the following:
• Making a cut with incorrect blade depth.
• Sawing into knots or nails in the work piece.
• Twisting the wood while making a cut.
• Failing to support the workpiece.
• Forcing a cut.
• Cutting warped or wet lumber.
• Using the wrong blade for the type of cut.
• Not following correct operating procedures.
• Misusing the saw.
• Failing to use the anti-kickback pawls.
• Cutting with a dull, gummed-up, or improperly set blade.
Precautions of kickback
NOTE: Kickback can be avoided by taking following proper precautions:
• Never stand directly in line with the saw blade. Always position your body on the same side of the saw blade as the fence.
Kickback may propel the workpiece at high velocity towards anyone standing in front and in line with the saw blade.
• Never reach over or in back of the saw blade to pull or to support the workpiece. Accidental contact with the saw blade
may occur or kickback may drag your ngers into the saw blade.
• Never hold and press the workpiece that is being cut off against the rotating saw blade. Pressing the workpiece being
cut off against the saw blade will create a binding condition and kickback.
• Align the fence to be parallel with the saw blade. A misaligned fence will pinch the workpiece against the saw blade and
create kickback.
• Use a featherboard to guide the workpiece against the table and fence when making non-through cuts such as rabbets,
dado cuts. A featherboard helps to control the workpiece in the event of a kickback.
• Use extra caution when making a cut into blind areas of assembled workpieces. The protruding saw blade may cut
objects that can cause kickback.
• Support large panels to minimize the risk of saw blade pinching and kickback. Large panels tend to sag under their own
weight. Support(s) must be placed under all portions of the panel overhanging the table top.
• Use extra caution when cutting a workpiece that is twisted, knotted, warped or does not have a straight edge to guide
it with a miter gauge or along the fence. A warped, knotted, or twisted workpiece is unstable and causes misalignment
of the kerf with the saw blade, binding and kickback.
• Never cut more than one workpiece, stacked vertically or horizontally. The saw blade could pick up one or more pieces
and cause kickback.
• When restarting the saw with the saw blade in the workpiece, center the saw blade in the kerf so that the saw teeth are
not engaged in the material. If the saw blade binds, it may lift up the workpiece and cause kickback when the saw is
restarted.
• Keep saw blades clean, sharp, and with sufcient set. Never use warped saw blades or saw blades with cracked or broken
teeth. Sharp and properly set saw blades minimize binding, stalling and kickback.
