If you are cutting on the bottom of the guide bar (the section of chain that is returning to the saw head), the force tends to pull the saw and the operator in toward the wood, or vise-versa This is called pull-in and can happen quickly. The operator may be pulled off balance, the wood might be thrown back at the operator, or the saw may be pulled forward, inadvertantly contacting something, causing kickback.

PULL-IN PROBLEM:

When cutting with the bottom of the bar on the top of a log, the natural reactive force tends to pull the saw in toward the wood.

Pull-in occurs when cutting on the bottom, far end of the bar. It can happen quickly enough to pull the operator off balance, losing control of the saw.

PULL-IN SOLUTION:

To prevent pull-in, work with the saw head close to the wood you are cutting.

Work with the saw head (not the tip) close to the wood. Always cut at full throttle and push down slowly enough to keep the engine and chain speed high. This cuts the wood rather than “biting” it.
