034 AV Super Stihl Chainsaw: 5 Pro Tips for Optimal Woodcutting
The Stihl 034 AV Super is a mid-range chainsaw renowned for its power and durability. It strikes a balance between manageable weight and sufficient engine displacement, making it suitable for a wide range of tasks, from felling medium-sized trees to bucking firewood. However, to truly unlock its potential, you need to understand its nuances and apply proven techniques.
Tip 1: Master the Art of Carburetor Tuning
The carburetor is the heart of any gasoline engine, and the 034 AV Super is no exception. Proper carburetor tuning is essential for optimal performance, fuel efficiency, and engine longevity. A poorly tuned carburetor can lead to a host of problems, including hard starting, poor idling, reduced power, and even engine damage.
-
Understanding the Carburetor: The carburetor’s primary function is to mix air and fuel in the correct proportions to create a combustible mixture. It has three main adjustment screws:
- “L” (Low-Speed) Screw: Controls the fuel mixture at idle and low engine speeds.
- “H” (High-Speed) Screw: Controls the fuel mixture at high engine speeds.
- “LA” (Idle Speed) Screw: Adjusts the engine’s idle speed.
-
The Tuning Process:
-
Warm-Up: Start the chainsaw and let it warm up for a few minutes. This ensures that the engine is at its operating temperature, which is crucial for accurate tuning.
- Idle Speed Adjustment: Turn the “LA” screw until the engine idles smoothly without the chain moving. If the chain is moving, turn the screw counterclockwise to reduce the idle speed. If the engine stalls, turn it clockwise to increase the idle speed.
- Low-Speed Adjustment: Turn the “L” screw until the engine accelerates smoothly from idle to full throttle. If the engine hesitates or bogs down, turn the screw slightly counterclockwise to richen the mixture. If the engine runs roughly or smokes excessively, turn the screw slightly clockwise to lean the mixture.
- High-Speed Adjustment: This is the most critical adjustment. Run the chainsaw at full throttle and listen to the engine. The goal is to find the point where the engine runs smoothly and powerfully without sounding strained or “lean.” A lean mixture (too little fuel) can cause the engine to overheat and seize. A rich mixture (too much fuel) can cause excessive smoking and reduced power. I usually start by turning the “H” screw clockwise until the engine begins to sound strained, then gradually turn it counterclockwise until the engine runs smoothly and powerfully. It’s a delicate balance.
- Fine-Tuning: After making these adjustments, let the engine cool down and recheck the idle speed. You may need to make minor adjustments to the “LA” screw to ensure a smooth idle.
- Data Point: According to a study by the U.S. Forest Service, properly tuned chainsaws can reduce fuel consumption by up to 15% and extend engine life by as much as 20%.
- Troubleshooting: If you’re having trouble tuning the carburetor, check the fuel filter, air filter, and spark plug. A clogged fuel filter or air filter can restrict airflow and affect the fuel mixture. A fouled spark plug can also cause poor performance.
- My Experience: I once spent an entire afternoon trying to tune a chainsaw, only to discover that the fuel filter was completely clogged. Replacing the filter immediately solved the problem. Don’t overlook the simple things!
Tip 2: Chain Sharpening: The Key to Efficient Cutting
A sharp chain is the single most important factor in efficient and safe woodcutting. A dull chain not only requires more effort and fuel but also increases the risk of kickback and other accidents. I can’t stress this enough: learn to sharpen your chain properly.
- Understanding Chain Anatomy: The cutting chain consists of several components, including cutters, rakers (depth gauges), and tie straps. The cutters are the actual cutting teeth, while the rakers control the depth of the cut.
-
Tools of the Trade:
- Round File: Used to sharpen the cutters. The correct file size depends on the chain pitch. For the 034 AV Super, a 5/32″ or 3/16″ file is typically used.
- Flat File: Used to lower the rakers.
- File Guide: Helps maintain the correct filing angle and depth.
- Depth Gauge Tool: Used to measure the raker height.
-
The Sharpening Process:
-
Secure the Chainsaw: Clamp the chainsaw in a vise or use a stump vise to hold it securely.
- Identify the Correct Filing Angle: The correct filing angle is typically marked on the chain or in the chainsaw’s owner’s manual. For the 034 AV Super, the recommended filing angle is usually around 30 degrees.
- File the Cutters: Using the round file and file guide, sharpen each cutter by filing from the inside out. Maintain the correct filing angle and depth. Make sure to file each cutter equally to ensure a balanced chain. I usually count the number of strokes for each cutter to ensure consistency.
- Lower the Rakers: After sharpening the cutters, check the raker height. The rakers should be slightly lower than the cutters. Use the depth gauge tool to measure the raker height and the flat file to lower them as needed.
- Check the Chain Tension: After sharpening, check the chain tension and adjust it as necessary.
- Data Point: A study by Oregon Tool found that properly sharpened chains can reduce cutting time by up to 50% and fuel consumption by up to 20%.
- My Experience: I used to think that chain sharpening was a tedious chore, but I quickly realized that it’s an essential skill for any serious woodcutter. Once I learned the proper technique, I was amazed at how much easier and faster it was to cut wood. Plus, I felt much safer knowing that I was using a sharp chain.
- Pro Tip: Invest in a good quality file guide. It will help you maintain the correct filing angle and depth, resulting in a sharper and more consistent chain.
Tip 3: Selecting the Right Bar and Chain Combination
The bar and chain are the business end of the chainsaw, and choosing the right combination is crucial for optimal performance and safety. The length of the bar determines the size of the trees you can safely fell, while the chain type affects the cutting speed and efficiency.
- Bar Length: The 034 AV Super is typically used with bar lengths ranging from 16 to 20 inches. The appropriate bar length depends on the size of the trees you’ll be cutting. A shorter bar is more maneuverable and easier to control, while a longer bar allows you to fell larger trees.
- Chain Pitch and Gauge: The chain pitch is the distance between the rivets on the chain, while the gauge is the thickness of the drive links. The 034 AV Super typically uses a .325″ pitch chain with a .050″ gauge.
-
Chain Types: There are several different types of chainsaw chains available, each designed for specific applications.
- Full Chisel Chains: These chains have square-cornered cutters that provide the fastest cutting speed. However, they are also more prone to kickback and require more frequent sharpening.
- Semi-Chisel Chains: These chains have rounded-corner cutters that are more durable and less prone to kickback than full chisel chains. They are a good all-around choice for general woodcutting tasks.
- Low-Kickback Chains: These chains are designed to reduce the risk of kickback. They have special features, such as bumper drive links and depth gauges, that help prevent the chain from grabbing and throwing the chainsaw back towards the operator.
- My Recommendation: For general woodcutting tasks, I recommend using a semi-chisel chain with a 18-inch bar. This combination provides a good balance of cutting speed, durability, and safety. If you’re a beginner, consider using a low-kickback chain for added safety.
- Case Study: I once worked on a project where we had to fell a large number of oak trees. We started out using full chisel chains, but we quickly realized that they were too aggressive for the hard oak wood. We switched to semi-chisel chains, and the cutting speed was still good, but the chains lasted much longer.
- Considerations: When selecting a bar and chain, consider the type of wood you’ll be cutting, the size of the trees, and your skill level. If you’re unsure which combination is right for you, consult with a qualified chainsaw dealer.
Tip 4: Mastering Felling Techniques for Safety and Efficiency
Felling trees is one of the most dangerous tasks in woodcutting. It requires careful planning, precise execution, and a thorough understanding of tree behavior. I’ve seen too many accidents in the woods, and I want to emphasize the importance of safety.
- Pre-Felling Assessment: Before felling any tree, take the time to assess the situation. Look for potential hazards, such as dead limbs, power lines, and other trees that could be affected by the falling tree. Also, consider the tree’s lean, wind direction, and the surrounding terrain.
- Planning the Felling Direction: The goal is to fell the tree in a safe and predictable direction. Consider the tree’s natural lean, the wind direction, and any obstacles in the area. If possible, fell the tree in the direction of its lean.
-
The Felling Cuts:
- Notch Cut: The notch cut is a wedge-shaped cut that directs the tree’s fall. It should be made on the side of the tree facing the desired felling direction. The notch cut should be about one-third of the tree’s diameter.
- Back Cut: The back cut is made on the opposite side of the tree from the notch cut. It should be made slightly higher than the notch cut and should leave a hinge of wood connecting the two cuts. The hinge controls the tree’s fall and prevents it from kicking back.
-
The Felling Process:
-
Clear the Area: Before making the felling cuts, clear the area around the tree of any obstacles.
- Make the Notch Cut: Carefully make the notch cut, ensuring that the two cuts meet at the correct angle.
- Make the Back Cut: Slowly and carefully make the back cut, leaving a hinge of wood.
- Monitor the Tree: As you make the back cut, monitor the tree for any signs of movement. If the tree starts to fall prematurely, stop cutting and move away from the tree.
- Escape Route: Always have a clear escape route planned before felling any tree.
- Data Point: According to the Occupational Safety and Health Administration (OSHA), felling trees is one of the most dangerous occupations in the United States. Proper training and adherence to safety procedures can significantly reduce the risk of accidents.
- My Experience: I once witnessed a near-fatal accident when a tree kicked back and struck a logger in the head. The logger was not wearing a helmet and suffered serious injuries. This experience taught me the importance of always wearing appropriate safety gear and following proper felling procedures.
- Safety First: Always wear a helmet, eye protection, hearing protection, and appropriate clothing when felling trees. Never work alone, and always have a spotter to watch for hazards.
