Quick Answer
For beginners, effective chainsaw chain grinding is crucial for optimal performance and longevity. Grinding should be done with a proper grinding tool and technique to achieve the correct angle and gauge. This process requires attention to detail and regular maintenance.
Choosing the Right Grinding Tool
When selecting a grinding tool, look for one specifically designed for chainsaw chains, such as a file or a stone grinder. A good quality file should have a coarse grit on one side and a finer grit on the other. For beginners, it’s recommended to use a file with a coarse grit first to remove old chain wear and then switch to the finer grit for polishing.
Grinding Technique
To grind the chain, position the saw on a stable work surface and adjust the chain so it’s in its normal running position. Set the grinding tool to the correct angle, typically between 30 to 40 degrees. Hold the saw firmly and use a gentle back-and-forth motion, applying moderate pressure. Begin at the center of the tooth and work your way to the edge. Grind the tooth about 1/8 inch deep, then inspect to see if it’s at the correct gauge.
Maintaining the Proper Gauge
The gauge of a chainsaw chain refers to the distance between the top of the tooth and the saw plate. A good starting point for most chains is a gauge of 0.024 inches. To check the gauge, place the chain on a gauge pin or a ruler, and measure from the top of the tooth to the saw plate. If the gauge is too wide, it can cause the chain to vibrate excessively and lead to premature wear. To adjust the gauge, use a file or a gauge tool to carefully grind the teeth.
