Ryobi Ryobi RY40550 40V HP Brushless 14 in. Chainsaw KICKBACK Error Fix: Guide Bar Kickback During Cutting

The chainsaw bar kicks upward and back toward the operator during cutting. Kickback is the most dangerous chainsaw hazard and occurs when the upper quadrant of the bar tip contacts wood (or another object) or when the chain is pinched in the cut. Prevention: Never cut with the tip of the bar — always use the bottom of the bar for cutting. Do not start a cut with the bar tip touching wood. Maintain a firm grip with both hands (left hand on front handle with thumb wrapped around, right hand on rear handle). Keep the chain sharp — a dull chain requires more pressure and is more likely to bind. Keep proper chain tension — a loose chain is more prone to catching. Be aware of branches under spring tension that can close a cut and pinch the chain. The Ryobi 40V chainsaw has an inertia-activated chain brake that should engage during a kickback event. If kickback occurred and the brake engaged, release the brake, reposition the workpiece, and continue cutting with proper technique.
