Frequently Asked Questions
How do I know when my chainsaw chain is dull?
You will notice the saw starts producing fine sawdust instead of large wood chips. The chain might also pull to one side while cutting, or you might find yourself applying excessive pressure to force the saw through the wood. If the saw creates smoke or the chain feels warm to the touch, it is time to sharpen.
Is it better to sharpen by hand or use a machine?
Hand filing is more gentle on the metal and removes less material, which extends the life of your chain. Machines work much faster and are excellent for restoring a chain that has hit a rock or dirt. Most professionals keep a manual file for daily maintenance and a bench grinder for occasional deep resets.
How many times can I sharpen a chain before it needs replacing?
You can typically sharpen a chain 10 to 15 times before the cutters become too small to be effective. Keep an eye on the wear indicator marks stamped onto the top of the cutters. Once you file back to those lines, the structural integrity of the metal is compromised and you should swap in a new chain.
What is the most important angle to get right?
The top plate angle is the primary factor in how efficiently your saw bites into the wood. Most standard chains require an angle of 30 degrees, though you should always confirm this with the manufacturer’s documentation. An incorrect angle results in a saw that struggles to penetrate the surface.
Should I wear protective gear while sharpening?
Yes, you should always wear durable work gloves to protect your hands from the extremely sharp teeth of the chain. It is also wise to wear safety glasses to prevent metal filings from entering your eyes. Even when the saw is powered off, a chain is sharp enough to cause significant injury.
