Let’s talk about the Stihl 011 AV chainsaw. It’s a workhorse, a classic, and a tool that, with proper care, can serve you well for years. I’ve spent countless hours in the woods, and the 011 AV has been a reliable companion for many of those. This guide isn’t just about the technical specifications; it’s about my experiences, the lessons I’ve learned, and the pro tips I’ve gathered along the way. Whether you’re a seasoned logger or just starting to clear your backyard, this guide will help you get the most out of your Stihl 011 AV.

Why focus on an older model? Because understanding the fundamentals of chainsaw operation and maintenance is crucial, regardless of the specific model. The 011 AV, with its relatively simple design, is an excellent platform for learning these fundamentals. Moreover, many of these saws are still in use today, often passed down through generations. Knowing how to keep them running is a valuable skill.

Understanding Key Concepts: Green Wood vs. Seasoned Wood

Before diving into the specifics of the Stihl 011 AV, let’s clarify a few key concepts that are essential for anyone working with wood.

Green Wood: This is freshly cut wood that has a high moisture content. It’s heavier than seasoned wood and more difficult to split. Green wood is also more prone to warping and cracking as it dries. Felling trees often involves cutting green wood.
Seasoned Wood: This is wood that has been allowed to dry, reducing its moisture content. Seasoned wood is lighter, easier to split, and burns more efficiently. Firewood is typically seasoned before use. The drying process can take anywhere from six months to two years, depending on the type of wood and the climate.

The type of wood you’re cutting directly impacts the performance of your chainsaw. Green wood, with its higher moisture content, requires more power and a sharper chain. Seasoned wood, on the other hand, is less demanding but can still dull the chain over time.

Section 1: Mastering the Basics of Stihl 011 AV Operation

The Stihl 011 AV is a relatively straightforward chainsaw to operate, but understanding the basics is crucial for safety and efficiency.

Step 1: Starting the Chainsaw

Safety First: Ensure you are wearing appropriate safety gear, including eye protection, hearing protection, gloves, and sturdy footwear. Clear the area of any obstacles or bystanders.
Fuel and Oil: Check the fuel and oil levels. The 011 AV uses a 50:1 fuel-to-oil ratio. This means 50 parts gasoline to 1 part two-stroke oil. Use high-quality two-stroke oil specifically designed for air-cooled engines. The chain oil reservoir should be filled with bar and chain oil. I personally use a synthetic bar and chain oil, especially in colder weather, as it flows better.
Choke: Engage the choke. On the 011 AV, the choke lever is typically located near the carburetor. For a cold start, pull the choke lever all the way out.
Primer Bulb (If Equipped): Some 011 AV models may have a primer bulb. Press it several times to prime the carburetor.
Starting Position: Place the chainsaw on the ground, ensuring the chain is not touching anything. Secure the saw by placing your foot through the rear handle.
Pull the Starter Cord: Grip the starter cord handle firmly and pull it sharply. Continue pulling until the engine starts. It may take several pulls, especially if the engine is cold.
Disengage the Choke: Once the engine starts, immediately push the choke lever in halfway, then fully in after a few seconds as the engine warms up.
Warm-Up: Allow the engine to warm up for a few minutes before using the chainsaw.

Personal Experience: I remember one time, I was trying to start my 011 AV on a cold morning, and it just wouldn’t fire up. After checking everything, I realized I had forgotten to mix the fuel correctly. I had used too much oil, which was preventing the engine from starting. Always double-check your fuel mixture!

Step 2: Making a Cut

Stance: Maintain a stable stance with your feet shoulder-width apart.
Grip: Grip the chainsaw firmly with both hands. Your thumbs should be wrapped around the handles.
Cutting Technique: Let the weight of the chainsaw do the work. Avoid forcing the saw through the wood. Use a smooth, controlled motion.
Kickback: Be aware of the risk of kickback, which occurs when the tip of the chainsaw bar comes into contact with an object. To avoid kickback, avoid using the tip of the bar and maintain a firm grip on the chainsaw.
Limbing: When limbing (removing branches from a felled tree), work from the base of the tree towards the top. This minimizes the risk of the tree rolling on you.
Felling: Felling (cutting down a tree) is a more complex task that requires careful planning and execution. It’s crucial to understand the lean of the tree, the wind direction, and the surrounding environment. Always use proper felling techniques, including making a notch cut and a back cut.

Data and Insights: According to the Occupational Safety and Health Administration (OSHA), most chainsaw accidents are caused by kickback. Proper training and the use of personal protective equipment can significantly reduce the risk of injury.

Step 3: Stopping the Chainsaw

Release the Throttle: Release the throttle lever to allow the engine to idle.
Engage the Chain Brake: Engage the chain brake to stop the chain from rotating.
Turn Off the Engine: Turn off the engine using the on/off switch.

Section 2: Essential Maintenance for Longevity

Regular maintenance is crucial for keeping your Stihl 011 AV running smoothly and extending its lifespan.

Step 1: Chain Sharpening

A sharp chain is essential for efficient cutting and safety. A dull chain requires more force, which can lead to fatigue and increase the risk of kickback.

Tools: You’ll need a chainsaw file, a file guide, and a depth gauge tool. The file size will depend on the chain pitch. For the 011 AV, a 5/32″ file is typically used.
Filing Angle: Use the file guide to maintain the correct filing angle. The angle is typically marked on the file guide.
Filing Technique: File each tooth consistently, using smooth, even strokes. File from the inside of the tooth to the outside.
Depth Gauge: Check the depth gauge after sharpening the chain. The depth gauge should be slightly lower than the cutting teeth. Use the depth gauge tool to adjust the depth gauge if necessary.

Case Study: I once worked with a logger who swore he could sharpen a chain freehand in under a minute. While his speed was impressive, his technique was inconsistent, and his chains wore out much faster than mine. Using a file guide ensures consistent sharpening and prolongs the life of your chain.

Step 2: Air Filter Cleaning

A clean air filter is essential for proper engine performance. A clogged air filter restricts airflow, which can lead to reduced power and increased fuel consumption.

Location: The air filter is typically located under a cover on the top or side of the chainsaw.
Removal: Remove the air filter cover and carefully remove the air filter.
Cleaning: Clean the air filter with compressed air or warm soapy water. Allow the air filter to dry completely before reinstalling it.
Replacement: Replace the air filter if it is damaged or excessively dirty.

Step 3: Spark Plug Inspection and Cleaning

The spark plug is responsible for igniting the fuel-air mixture in the engine. A fouled or damaged spark plug can cause starting problems or poor engine performance.

Location: The spark plug is typically located on the side of the engine.
Removal: Disconnect the spark plug wire and use a spark plug wrench to remove the spark plug.
Inspection: Inspect the spark plug for signs of damage or fouling.
Cleaning: Clean the spark plug with a wire brush or spark plug cleaner.
Gap Adjustment: Check the spark plug gap and adjust it if necessary. The correct gap for the 011 AV is typically 0.5 mm (0.020 inches).
Reinstallation: Reinstall the spark plug and tighten it to the correct torque.

Step 4: Bar and Chain Maintenance

The bar and chain are the heart of the chainsaw. Proper maintenance is crucial for ensuring efficient cutting and prolonging their lifespan.

Bar Cleaning: Clean the bar regularly with a wire brush to remove dirt and debris.
Bar Groove Cleaning: Clean the bar groove with a screwdriver or a specialized bar groove cleaner.
Bar Rail Dressing: Dress the bar rails with a file to remove any burrs or damage.
Chain Tension: Check the chain tension regularly and adjust it as needed. The chain should be snug against the bar but still able to be pulled around by hand.
Chain Lubrication: Ensure the chain is properly lubricated. The chain oil reservoir should be filled with bar and chain oil. Check the oiler output regularly to ensure the chain is receiving adequate lubrication.

Strategic Advantage: Investing in high-quality bar and chain oil can significantly extend the life of your bar and chain. I’ve found that synthetic oils provide superior lubrication and protection, especially in demanding conditions.

Section 4: 5 Pro Tips for Repairing and Using Your Stihl 011 AV

Here are five pro tips that I’ve learned over the years that can help you get the most out of your Stihl 011 AV.

Tip 1: Master the Art of Carburetor Tuning

Carburetor tuning is crucial for optimal engine performance. The Stihl 011 AV carburetor typically has three adjustment screws: the low-speed screw (L), the high-speed screw (H), and the idle speed screw (T).

Low-Speed Screw (L): This screw controls the fuel mixture at low engine speeds. Adjusting this screw can improve idling and acceleration.
High-Speed Screw (H): This screw controls the fuel mixture at high engine speeds. Adjusting this screw can improve power and prevent engine damage.
Idle Speed Screw (T): This screw controls the engine’s idle speed. Adjusting this screw can prevent the engine from stalling.

The correct carburetor settings will vary depending on the altitude, temperature, and humidity. Refer to the owner’s manual for the recommended settings.

My Method: I start by adjusting the low-speed screw until the engine idles smoothly without stalling. Then, I adjust the high-speed screw until the engine reaches its maximum RPM without sputtering or hesitating. Finally, I adjust the idle speed screw until the chain stops rotating at idle.

Tip 2: Use the Right Chain for the Job

There are many different types of chainsaw chains available, each designed for a specific purpose. Using the wrong chain can reduce cutting efficiency and increase the risk of kickback.

Full Chisel Chain: This type of chain has square-cornered teeth and is designed for fast cutting in clean wood.
Semi-Chisel Chain: This type of chain has rounded-cornered teeth and is more durable than a full chisel chain. It’s a good choice for cutting in dirty or abrasive wood.
Low-Profile Chain: This type of chain has a smaller kerf (the width of the cut) and is designed for smaller chainsaws.

For the Stihl 011 AV, I recommend using a semi-chisel chain for general-purpose cutting.

Tip 3: Keep Your Chain Oiler Clean

A properly functioning chain oiler is essential for prolonging the life of your bar and chain. A clogged oiler can cause the chain to overheat and wear out prematurely.

Check the Oiler Output: Regularly check the oiler output by running the chainsaw at full throttle and observing the amount of oil being thrown off the chain.
Clean the Oiler: If the oiler is not working properly, clean it with compressed air or a small wire.
Check the Oiler Filter: The oiler filter is located inside the oil tank and can become clogged with debris over time. Replace the oiler filter if it is dirty or damaged.

Unique Insight: I’ve found that using a small amount of kerosene in the bar and chain oil can help to keep the oiler clean and prevent it from clogging. However, be careful not to use too much kerosene, as it can damage the bar and chain.

Tip 4: Store Your Chainsaw Properly

Proper storage is essential for preventing damage to your chainsaw.

Drain the Fuel: Before storing your chainsaw for an extended period, drain the fuel tank to prevent the fuel from going stale.
Clean the Chainsaw: Clean the chainsaw thoroughly to remove dirt and debris.
Store in a Dry Place: Store the chainsaw in a dry place to prevent rust and corrosion.
Remove the Chain and Bar: For long-term storage, it’s a good idea to remove the chain and bar and store them separately. This will prevent the chain from rusting and the bar from becoming bent.

Safety should always be your top priority when operating a chainsaw. Invest in quality safety gear, including:

Eye Protection: Wear safety glasses or a face shield to protect your eyes from flying debris.
Hearing Protection: Wear earplugs or earmuffs to protect your hearing from the loud noise of the chainsaw.
Gloves: Wear sturdy gloves to protect your hands from cuts and abrasions.
Chaps: Wear chainsaw chaps to protect your legs from accidental cuts.
Steel-Toed Boots: Wear steel-toed boots to protect your feet from falling objects.

Data and Insights: According to the International Society of Arboriculture (ISA), wearing appropriate safety gear can reduce the risk of chainsaw injuries by up to 80%.

Section 5: Strategic Wood Processing and Firewood Preparation

Now that you’re comfortable with the Stihl 011 AV, let’s talk about how to use it effectively for wood processing and firewood preparation.

Felling Techniques

Planning: Before felling a tree, assess the lean of the tree, the wind direction, and the surrounding environment. Clear the area of any obstacles or bystanders.
Notch Cut: Make a notch cut on the side of the tree that you want it to fall. The notch cut 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 between the notch cut and the back cut.
Felling: Push the tree over using a felling wedge or a felling lever.

Debarking Logs

Debarking logs can help to speed up the drying process and prevent insect infestations.

Tools: You can use a drawknife, a barking spud, or a debarking machine to remove the bark from logs.
Technique: Use the drawknife or barking spud to peel the bark off the log. Be careful not to damage the wood underneath the bark.

Splitting Firewood

Splitting firewood makes it easier to dry and burn.

Tools: You can use an axe, a maul, or a log splitter to split firewood.
Technique: Place the log on a chopping block and swing the axe or maul down onto the log. If you’re using a log splitter, place the log on the splitter and activate the hydraulic ram.

Cost Analysis: While an axe and maul are cheaper upfront, a hydraulic log splitter can significantly increase your efficiency, especially if you’re splitting large quantities of firewood. A good quality hydraulic splitter can split a cord of wood in a fraction of the time it would take with an axe.

Drying Methods

Proper drying is essential for producing high-quality firewood.

Stacking: Stack the firewood in a single row, with the bark side up. This will allow the wood to dry more quickly.
Location: Stack the firewood in a sunny, well-ventilated location.
Covering: Cover the firewood with a tarp to protect it from rain and snow.

Moisture Content Targets: The ideal moisture content for firewood is between 15% and 20%. You can use a moisture meter to check the moisture content of your firewood.

Stacking Firewood

Properly stacking firewood is important for both drying and storage.

Foundation: Create a solid foundation for your woodpile using pallets or logs.
Stability: Stack the wood in a way that is stable and prevents it from collapsing.
Airflow: Leave gaps between the rows of wood to allow for airflow.

Case Study: I once helped a friend stack his firewood in a circular pattern around a tree stump. It looked beautiful, but it was a disaster for drying. The wood in the center of the pile never dried properly, and it became infested with mold. A simple, single-row stack is always the most effective method.
