What is the recommended entering angle for starting a cut?

• A. 0 degree
• B. 90 degree angle
• C. 180 degree angle
• D. 45-75 degree angle entering cut

Answer: (D)

When starting a cut, how you bring the bar into the wood greatly affects control and kickback risk. Entering at about 45–75 degrees lets the chain engage gradually, keeps the bar nose from slamming straight into the wood, and gives you stable steering as you begin the cut. A flat 0-degree entry can ride along the surface and pinch; a 90-degree entry drives the bar straight in, increasing the chance of a sudden bite or kickback; 180 degrees would come from the opposite direction with poor control. So the 45–75 degree entering angle is the safe, controllable way to start a cut.
