Use low-kickback chains Certain chainsaw chains are better for kickback than others. Use a sharp chain As mentioned above, a dull chain can cause kickback, as the teeth will not be able to cut through the wood, which will cause the chain to get stuck and cause kickback.

What can we be doing to prevent kickback accidents? It starts with an understanding of kickback and what causes it to occur — and ends with always remaining vigilant when it comes to safe chain saw operation and maintenance.
Any chain saw is a powerful piece of equipment. No matter the size of the individual saw, signifi cant force and power keep the cutting chain rotating at high speeds so as to effi ciently cut through wood. Throughout operation, that force that keeps the chain moving is acting just the same on the body of the saw as it is on the chain itself.
With an operator holding the body of the saw steady, the force causes the chain to rotate as intended. This is commonly known as rotational kickback. Why does this happen? Under ordinary circumstances, the saw chain very quickly shaves many thin strips of wood out of a cut. Those thin cuts are critical here. The depth of each individual cut made by the saw chain is determined by the raker, or depth gauge. The raker passes across the top of the existing cut, or wood surface, and determines the thickness of material being shaved off by the leading edge of the cutter tooth.
