Frequently Asked Questions (FAQs)
How often should I use a chainsaw chain sharpener?
You should sharpen your chain as soon as you notice it producing dust instead of wood chips, or if you have to apply force to get the saw to cut. Regular light sharpening is better than waiting until the chain is completely dull.
Is an electric sharpener better than a manual file?
Electric sharpeners are generally faster and provide more consistent results for the average user. While manual filing allows for great precision, it requires significant skill and time to master.
Do I need to remove the chain to sharpen it?
Most handheld electric sharpeners, like the ones listed here, allow you to sharpen the chain while it is still on the bar. This saves time and makes mid-job maintenance much easier.
What angle should I sharpen my chainsaw chain at?
Most standard chainsaw chains require a sharpening angle of 30 degrees. However, always check your chain manufacturer’s specifications, as some specialty chains may require different angles.
How long do the sharpening stones last?
Standard grinding stones wear down over time and lose their shape, usually lasting for 5-10 sharpenings depending on usage. Titanium-coated or diamond wheels, like those found in the EzzDoo kits, last significantly longer.
