A sharp chain is paramount to efficient and safe woodcutting. A dull chain not only requires more effort and fuel but also increases the risk of kickback. I can’t stress enough how important this is. I’ve seen firsthand how a dull chain can lead to accidents.

Frequency: Sharpen the chain every time you refuel or notice a decrease in cutting performance.
Tools: Use a chainsaw sharpening kit with the correct file size for your chain (typically 4.0 mm or 5/32 inch for the 020AV). A depth gauge tool is also essential.
Technique:
1. Secure the chainsaw in a vise.
2. File each cutter tooth at the correct angle (usually 30 degrees). Maintain a consistent angle and pressure.
3. Lower the depth gauges after every few sharpenings to ensure proper cutting depth.
4. Use a flat file and depth gauge tool to maintain the correct depth gauge setting.

I remember one instance where I was cutting through some seasoned oak with a noticeably dull chain. The saw was vibrating excessively, and I had to force it through the wood. After taking the time to properly sharpen the chain, the difference was night and day. The saw cut smoothly and effortlessly, and I was able to work much more efficiently.

Takeaway: Regularly sharpen your chainsaw chain to maintain optimal cutting performance and reduce the risk of accidents. A sharp chain makes all the difference.

Tip #2: Fuel and Oil: The Lifeblood of Your Chainsaw

Using the correct fuel and oil mixture is crucial for the longevity of your Stihl 020AV. Stihl recommends a fuel-to-oil ratio of 50:1 for this model. Using the wrong mixture can lead to engine damage and reduced performance.

Fuel: Use high-quality unleaded gasoline with a minimum octane rating of 89.
Oil: Use Stihl-approved two-stroke engine oil or a high-quality synthetic two-stroke oil.
Mixing: Accurately measure the fuel and oil using a calibrated mixing bottle. Thoroughly mix the fuel and oil before adding it to the chainsaw’s fuel tank.

I learned this the hard way when I first started using chainsaws. I mistakenly used a lower-quality oil and didn’t mix it properly with the fuel. As a result, the engine started smoking excessively, and the performance deteriorated rapidly. After switching to the correct fuel and oil mixture, the engine ran much smoother and more efficiently.

Safety Gear: Always wear appropriate safety gear, including a helmet, eye protection, hearing protection, gloves, and chainsaw chaps.
Notch Cut: Make a notch cut on the side of the tree facing the desired felling direction. The notch should be about one-third of the tree’s diameter.
Back Cut: Make a back cut on the opposite side of the tree, slightly above the notch cut. Leave a hinge of wood to control the tree’s fall.
Wedges: Use felling wedges to help guide the tree’s fall and prevent the saw from getting pinched.

I recall one instance where I was felling a small maple tree in my backyard. I had carefully planned the felling direction and made the notch and back cuts according to the proper technique. However, as the tree started to fall, it began to lean in the wrong direction. I quickly inserted a felling wedge into the back cut, which helped to redirect the tree’s fall and prevent it from landing on my shed.

Tree Diameter: The 020AV is best suited for trees with a diameter of 12 inches or less.
Terrain: Be mindful of the terrain. Uneven ground can affect the tree’s fall.

Takeaway: Always plan your felling operation carefully and use proper felling techniques to ensure safety and control. Felling wedges can be invaluable for guiding the tree’s fall.

Tip #4: Efficient Limbing and Bucking Techniques

Limbing and bucking are essential steps in preparing firewood and processing timber. The Stihl 020AV’s lightweight design makes it ideal for these tasks.

Limbing: Remove the branches from the felled tree, starting from the base and working towards the top. Use a sweeping motion to avoid kickback.
Bucking: Cut the tree trunk into manageable lengths for firewood or timber. Use a sawbuck or other support to keep the trunk off the ground.
Safety: Always maintain a firm grip on the chainsaw and keep your feet firmly planted on the ground. Be aware of the potential for kickback, especially when cutting small branches.

One time, I was limbing a large oak tree that had fallen during a storm. The branches were thick and heavy, and I was struggling to cut them safely. I realized that I was trying to cut the branches from the top down, which was causing the saw to bind and kick back. After switching to a bottom-up approach, the limbing process became much easier and safer.

Wood Type: Different wood types require different cutting techniques. Hardwoods like oak and maple require more power than softwoods like pine and fir.
Bar Length: Use a shorter bar length for limbing to improve maneuverability.
