Sharpening a Chainsaw Chain this way…

Sharpening a chainsaw chain by hand using a round file and a file guide, also known as a file holder or file guide, is a valuable skill for chainsaw owners. Properly sharpened chains ensure efficient cutting, prolong the life of the chain, and enhance safety. Here's a step-by-step guide on how to sharpen a chainsaw chain by hand:
Materials and Tools Needed:
Chainsaw file guide (file holder)
Round chainsaw file (correct size for your chain)
Flat file (for depth gauge adjustment)
Depth gauge tool (depth gauge guide)
Chainsaw safety gear (gloves, safety glasses, and hearing protection)
Step-by-Step Guide:
Prepare the Chainsaw:
Ensure the chainsaw is turned off, and the spark plug is disconnected.
Secure the chainsaw bar in a bench vise or use a clamp-on chainsaw vise to immobilize it. Make sure it's stable and won't move during sharpening.
Identify the Cutter Teeth:
Examine the chain and identify the cutter teeth. These are the sharp, pointed teeth that do the cutting.
Use the File Guide:
Place the file guide on the chain with the arrow or orientation mark facing forward, indicating the direction of the chain's rotation.
Position the file guide over the first cutter tooth to be sharpened.
Determine the File Angle:
Maintain the correct file angle, which is typically 25-30 degrees relative to the chain's top plate. Check your chainsaw's manual for the recommended angle.
File the Cutter Tooth:
Insert the round chainsaw file into the file guide's hole.
Keeping the file at the correct angle, push it across the cutter tooth from the base (where the tooth meets the chain) to the tip, using smooth and even strokes.
File in one direction only, away from your body. Lift the file off the tooth when you reach the tip.
Repeat this process for each cutter tooth, typically 3-5 strokes per tooth.
Check for Consistency:
After sharpening all the teeth on one side, examine them to ensure they have a consistent sharpness and angle. Adjust your technique if needed.
Adjust Depth Gauges (Rakers):
Periodically check and adjust the depth gauges (rakers) with a depth gauge tool.
Follow your chainsaw's specifications for depth gauge height. Use a flat file to lower any gauges that are too high.
Rotate the Chain:
Once you've sharpened all the teeth on one side, release the chainsaw bar from the vise and rotate it 180 degrees.
Reclamp the bar and sharpen the teeth on the other side using the same technique.
Maintain Consistent Teeth Length:
Keep an eye on the length of the cutter teeth while sharpening. Maintain consistent tooth length for even cutting.
Check Tension:
After sharpening and reassembling the chain, check its tension. Proper tension is crucial for safe and efficient operation.
Reassemble and Test:
Reassemble the chain on the chainsaw and test it by making a few test cuts in a safe and controlled environment.
Regular Maintenance:
Regularly inspect and sharpen the chain as needed to maintain optimal cutting performance.
Sharpening your chainsaw chain by hand takes practice to perfect, but it's a valuable skill for any chainsaw owner. Properly sharpened chains result in efficient cutting, reduced wear on the chainsaw, and increased safety during operation. Always follow your chainsaw manufacturer's guidelines and wear appropriate safety gear when working with chainsaws and sharp tools.
