My Personal Experience with the Stihl 034AV

My journey with the Stihl 034AV began about fifteen years ago. I stumbled upon a used one at a local pawn shop. It was a bit rough around the edges, but the price was right, and I was eager to tackle a growing pile of fallen trees on my property.

I remember the first time I fired it up. The pull cord felt stiff, and it took a few tries to get it going. But once it roared to life, I was hooked. The sound of that two-stroke engine, the smell of burning oil, the feeling of the saw biting into wood—it was intoxicating.

Over the years, that 034AV became my go-to tool for everything from clearing trails to cutting firewood. I’ve felled countless trees with it, bucked hundreds of cords of wood, and even used it to carve a few rustic benches for my garden.

It hasn’t always been smooth sailing. I’ve had my share of breakdowns and repairs. But each time, I’ve learned something new about the saw and about chainsaw maintenance in general. And that’s one of the things I appreciate most about the 034AV: it’s a learning tool as much as it is a cutting tool.

Key Concepts: Understanding Wood and Chainsaws

Before we dive into the pro tips, let’s cover some fundamental concepts.

Green Wood vs. Seasoned Wood:

• Green Wood: Wood that has been freshly cut and still contains a high moisture content (typically 30-60%). It’s heavier, harder to split, and burns poorly, producing a lot of smoke.
• Seasoned Wood: Wood that has been dried to a lower moisture content (ideally below 20%). It’s lighter, easier to split, and burns cleaner and more efficiently.

Why Seasoning Matters:

• Improved Burning Efficiency: Seasoned wood releases more heat per pound than green wood.
• Reduced Smoke: Seasoned wood produces less smoke, reducing air pollution and creosote buildup in your chimney.
• Easier Splitting: As wood dries, it becomes more brittle and easier to split.
• Reduced Weight: Seasoned wood is significantly lighter, making it easier to handle and transport.

Chainsaw Components:

• Engine: The power source of the chainsaw.
• Bar: The metal guide that supports the chain.
• Chain: The cutting element of the chainsaw, consisting of interlocking links with cutters.
• Clutch: Connects the engine to the chain, allowing the chain to stop when the engine is idling.
• Chain Brake: A safety device that stops the chain quickly in case of kickback.
• Carburetor: Mixes air and fuel to create a combustible mixture for the engine.
• Air Filter: Prevents dirt and debris from entering the engine.
• Spark Plug: Ignites the air-fuel mixture in the engine cylinder.

Types of Logging Tools:

• Axes: For splitting wood, felling small trees, and limbing.
• Sledges and Wedges: For splitting large logs.
• Cant Hooks: For rolling and positioning logs.
• Timber Jacks: For lifting logs off the ground for easier cutting.
• Chainsaw Winches: For pulling logs out of difficult terrain.
• Log Splitters: For splitting large quantities of firewood quickly and efficiently.

Pro Tips for Using the Stihl 034AV

Now, let’s get to the good stuff: the pro tips I’ve learned over the years that will help you get the most out of your Stihl 034AV.

1. Starting and Maintenance:

• The Starting Ritual: Cold starts can be tricky. I’ve found that using the choke properly is crucial. Engage the choke fully, pull the cord until the engine sputters, then disengage the choke and pull again. It usually starts on the second or third pull.
• Fuel Mix is Key: Always use the correct fuel-to-oil ratio (typically 50:1 for the 034AV). Using the wrong ratio can damage the engine. I always use a high-quality two-stroke oil specifically designed for chainsaws.
• Air Filter Cleaning: A clean air filter is essential for optimal engine performance. I clean mine after every use, especially when working in dusty conditions. Use compressed air or warm, soapy water.
• Spark Plug Inspection: Inspect the spark plug regularly. A fouled spark plug can cause starting problems and poor engine performance. Replace it if necessary.
• Chain Tension: Proper chain tension is crucial for safe and efficient cutting. The chain should be snug against the bar but still able to be pulled around by hand. Check the tension frequently, especially when the chain is new.
• Bar and Chain Oiling: Make sure the bar and chain oiler is working properly. The chain should be constantly lubricated to prevent overheating and premature wear. I always check the oil level before each use.

2. Sharpening the Chain:

• The Importance of a Sharp Chain: A sharp chain is not only more efficient but also safer. A dull chain can cause the saw to kick back, increasing the risk of injury.
• Filing Technique: I use a round file and a file guide to sharpen my chain. The key is to maintain the correct angle and depth. There are many online tutorials that demonstrate the proper technique.
• Depth Gauge Adjustment: The depth gauges (also known as rakers) control how much the cutters bite into the wood. They need to be filed down occasionally to maintain optimal cutting performance. Use a flat file and a depth gauge tool.
• Professional Sharpening: If you’re not comfortable sharpening your own chain, take it to a professional. A professional sharpening will ensure that the cutters are properly sharpened and the depth gauges are correctly adjusted.

3. Felling Trees Safely:

• Assess the Situation: Before felling a tree, take the time to assess the situation. Look for hazards such as power lines, other trees, and obstacles on the ground.
• Plan Your Escape Route: Always plan your escape route before making the first cut. Make sure the path is clear and that you can move quickly if necessary.
• The Notch Cut: The notch cut determines the direction the tree will fall. It should be about one-third of the tree’s diameter.
• The Back Cut: The back cut should be made slightly above the notch cut. Leave a hinge of wood to control the fall of the tree.
• Use Wedges: If the tree doesn’t start to fall on its own, use wedges to help guide it.
• “Timber!”: Always shout “Timber!” before the tree falls to warn anyone in the area.

4. Bucking Firewood Efficiently:

• Choose the Right Bar Length: The bar length should be appropriate for the size of the wood you’re cutting. A longer bar is needed for larger logs.
• Use a Sawbuck: A sawbuck is a simple wooden frame that holds logs in place while you cut them. It makes bucking firewood much easier and safer.
• Cut in a Safe Position: Always cut with your feet firmly planted on the ground. Avoid cutting above your head or in awkward positions.
• Avoid Pinching: Pinching occurs when the bar gets stuck in the wood. To avoid pinching, use wedges to keep the cut open.
• Cut in Sections: For large logs, cut them into smaller sections that are easier to handle.

5. Splitting Wood Effectively:

• Choose the Right Axe or Splitter: For smaller logs, an axe is sufficient. For larger logs, a sledge and wedges or a log splitter is recommended.
• Aim for the Cracks: Look for natural cracks in the wood and aim for those when splitting.
• Use a Tire: Placing the log inside a tire can help keep it in place while you split it. It also prevents the split pieces from flying away.
• Hydraulic Log Splitter: For large-scale firewood production, a hydraulic log splitter is a worthwhile investment. It makes splitting wood much faster and easier.

6. Wood Species and Firewood Quality:

• Hardwoods vs. Softwoods: Hardwoods (e.g., oak, maple, ash) are denser and burn longer and hotter than softwoods (e.g., pine, fir, spruce).
• BTU Content: BTU (British Thermal Unit) is a measure of the heat energy contained in wood. Higher BTU content means more heat per pound. Oak has a high BTU content, while pine has a lower BTU content.
• Seasoning Time: Hardwoods typically take longer to season than softwoods.
• Resin Content: Softwoods contain more resin than hardwoods. Burning resinous wood can produce more smoke and creosote.

Here’s a quick guide to some common firewood species:

7. Firewood Stacking and Drying:

• Location, Location, Location: Choose a sunny, well-ventilated location for your firewood stack.
• Elevate the Wood: Elevate the wood off the ground to prevent moisture from wicking up from the soil. Use pallets or scrap wood.
• Stacking Method: Stack the wood in rows with gaps between the rows to allow for air circulation.
• Cover the Top: Cover the top of the stack with a tarp to protect the wood from rain and snow. Leave the sides open to allow for ventilation.
• The 6-Month Rule: Aim to season your firewood for at least six months, preferably longer for hardwoods.
• Moisture Meter: Use a moisture meter to check the moisture content of the wood. Aim for a moisture content below 20%.

8. Chainsaw Safety Gear: Don’t Skimp!

• Helmet: Protects your head from falling branches and debris.
• Eye Protection: Safety glasses or a face shield protect your eyes from flying wood chips.
• Hearing Protection: Earplugs or earmuffs protect your hearing from the loud noise of the chainsaw.
• Gloves: Protect your hands from cuts and abrasions.
• Chaps: Chainsaw chaps are essential for protecting your legs from accidental cuts.
• Steel-Toed Boots: Protect your feet from falling logs and sharp objects.

9. Troubleshooting Common Problems:

• Chainsaw Won’t Start: Check the fuel, spark plug, air filter, and carburetor.
• Chainsaw Runs Poorly: Clean the air filter, adjust the carburetor, and check the spark plug.
• Chain Won’t Turn: Check the chain brake, clutch, and bar and chain oiler.
• Chain Keeps Binding: Check the chain tension, bar lubrication, and sharpness of the chain.
• Overheating: Ensure proper bar and chain lubrication, avoid forcing the saw, and clean the cooling fins on the engine.

10. Costs and Budgeting:

• Chainsaw Purchase (Used): $200 – $400
• Safety Gear: $100 – $200
• Maintenance Supplies (Oil, Fuel, Files): $50 – $100 per year
• Log Splitter (Optional): $500 – $2000
• Firewood Storage: $50 – $100 (for tarps and pallets)

These are just estimates. Costs will vary depending on your location and the specific equipment you choose.

Resource Management Tips:

• Source Wood Locally: Look for local sources of wood, such as fallen trees on your property or firewood suppliers in your area.
• Salvage Wood: Consider salvaging wood from construction sites or demolition projects.
• Barter: Trade firewood for other goods or services with your neighbors.
• Buy in Bulk: Buy firewood in bulk to save money.
• Season Wood Yourself: Seasoning your own firewood is much cheaper than buying seasoned wood.

Case Study: My Firewood Project Success

A few years ago, I decided to undertake a major firewood project. I had a large pile of fallen oak trees on my property, and I was determined to turn them into a winter’s worth of firewood.
