Kickback causes and related w arnings
Kickback is a sudden reaction of the workpiece due to a pinched, jammed saw blade or misaligned line of cut in the workpiece
with respect to the saw blade or when a part of the workpiece binds between the saw blade and the rip fence or other fixed
object.
Most frequently during kickback, the workpiece is lifted from the table by the rear portion of the saw blade and

is propelled towards the operator.
and can be avoided by taking proper precautions as given below.
Never stand directly in line w ith the saw blade.
b.
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 w orkpiece.
c.
saw blade may occur or kickback may drag your fingers into the saw blade.
Never hold and press the workpiece that is being cut off against the rotating saw blade.
d.
workpiece being cut off against the saw blade will create a binding condition and kickback.
e. Align the fence to be parallel w ith the saw blade.
and create kickback.
f. Use a featherboard to guide the w orkpiece against the table and fence w hen making non-through cuts such
as rabbeting, or resaw ing cuts.
Use extra caution w hen making a cut into blind areas of assembled w orkpieces.
