What is the function of the depth gauge (raker) on a chainsaw?

The function of the depth gauge, also known as the raker, on a chainsaw is to determine and control the cutting depth of the chain as it engages with the wood. The depth gauge sits in front of each cutter tooth and acts as a limiter for how deep the cutter can sink into the material being cut. By effectively managing this depth, it allows for safer and more efficient cutting, preventing the chain from digging too deep and causing kickback, as well as promoting steady cutting performance.

This is crucial, as an appropriate depth enhances the effectiveness of the cut while ensuring the operator maintains control over the saw. A properly adjusted depth gauge not only contributes to smoother cutting but also prolongs the life of the chain and improves overall safety during operation.
