Stihl 020AV Chainsaw Tips: 5 Pro Woodcutting Hacks

Here are five pro woodcutting hacks that I’ve found invaluable over the years, tailored specifically for the Stihl 020AV. These tips cover everything from chainsaw maintenance and sharpening to advanced cutting techniques and safety protocols.

1. Mastering Chainsaw Sharpening: The Key to Efficiency

A dull chain is a dangerous chain. It requires more force, increases the risk of kickback, and puts unnecessary strain on your chainsaw engine. Keeping your chain sharp is the single most important thing you can do to improve your woodcutting efficiency and safety.

Key Concepts:

• Raker Depth (Depth Gauge): The raker depth determines how much wood each cutter tooth can remove. If the rakers are too high, the chain won’t cut effectively. If they are too low, the chain will grab aggressively and increase the risk of kickback.
• Cutting Angle: The correct cutting angle ensures the tooth bites into the wood efficiently.
• Side Plate Angle: The side plate angle affects the smoothness and speed of the cut.
• Consistent Sharpening: Maintaining a consistent angle and depth across all teeth is crucial for even cutting.

Step-by-Step Guide to Sharpening:

1. Gather Your Tools: You’ll need a chainsaw sharpening kit that includes:
   • Round File: The correct size for your chain pitch (typically 5/32″ for the Stihl 020AV, but always verify).
   • Flat File: For filing down the rakers.
   • Depth Gauge Tool: To measure and adjust raker depth.
   • File Holder: To maintain the correct sharpening angle.
   • Vise or Chain Clamp: To secure the chainsaw bar.
2. Secure the Chainsaw: Clamp the chainsaw bar in a vise or use a chain clamp to keep it stable.
3. Identify the Correct Angles: Refer to your chainsaw manual or the chain packaging for the recommended sharpening angles. For the Stihl 020AV, the typical angles are:
   • Cutting Angle: 30 degrees (typically marked on the file holder)
   • Side Plate Angle: 60 degrees
4. Sharpen the Cutters:
   • Place the round file in the file holder, ensuring the correct angle.
   • File each tooth from the inside out, using smooth, consistent strokes.
   • Count the number of strokes for each tooth to ensure they are all sharpened equally. I usually aim for 3-5 strokes per tooth.
   • Pay attention to the length of the tooth. If one tooth is significantly shorter than the others, it may be damaged and need replacement.
5. File the Rakers (Depth Gauges):
   • Use the depth gauge tool to check the raker depth. The raker should be slightly lower than the top of the cutter.
   • If the raker is too high, use the flat file to carefully file it down until it’s level with the depth gauge tool.
   • Round off the front of the raker slightly to prevent grabbing.
6. Test the Chain: After sharpening, test the chain on a piece of wood. If it cuts straight and produces consistent chips, you’ve done a good job. If it pulls to one side or produces fine dust instead of chips, you may need to revisit the sharpening process.

Personalized Story/Experience:

I remember one time when I was cutting firewood with a dull chain. I was struggling to get through even small logs, and the chainsaw was overheating. I was frustrated and exhausted. Finally, I decided to take the time to sharpen the chain properly. The difference was night and day!
