Kickback
Kickback is a sudden, rearward motion of the saw that can
occur if the blades are stalled (pinched, jammed, twisted) in
the so called kickback zone. Most kickbacks are small and felt
as small ”jerks” in the front handle. However, kickback can be
very powerful. If you are not paying attention or have a poor
grip the saw can be thrown all the way back at you.
