1. Mastering the Art of Felling: Precision and Control

Felling a tree is more than just cutting it down. It’s a controlled process that requires careful planning and precise execution. A poorly felled tree can damage property, injure yourself or others, or result in significant waste. I’ve seen it happen, and believe me, the consequences aren’t pretty.

Why Directional Felling Matters:

Directional felling is the key to controlling where a tree falls. It allows you to avoid obstacles, minimize damage to surrounding trees, and position the tree for easier bucking. Proper directional felling can reduce the risk of “hang-ups,” where the tree gets caught in other trees, which can be extremely dangerous.

• Safety: The most important aspect. Control where the tree falls to avoid hazards.
• Efficiency: Position the tree for easier bucking and limbing.
• Waste Reduction: Minimize damage to the tree and surrounding vegetation.

The Anatomy of a Felling Cut:

The felling cut consists of three key components: the notch, the hinge, and the back cut. Each plays a crucial role in controlling the fall of the tree.

• The Notch (Face Cut): This is a wedge-shaped cut that determines the direction of the fall. The notch should be about 1/3 of the tree’s diameter. There are two main types of notches:
  • Open Face Notch: This is the most common type of notch and is suitable for most situations. It consists of a top cut at a 45-degree angle and a horizontal bottom cut that meets the top cut.
  • Humboldt Notch: This notch is used for larger trees and provides more control over the fall. It consists of a horizontal top cut and a bottom cut at a 45-degree angle.
• The Hinge: This is the strip of wood left between the notch and the back cut. It acts as a guide, controlling the direction and speed of the fall. The hinge should be about 1/10 of the tree’s diameter and of uniform thickness.
• The Back Cut: This is the final cut that severs the tree. It should be made slightly above the bottom of the notch, leaving the hinge intact.

Step-by-Step Guide to Felling:

1. Assess the Tree and Surroundings: Before you even start your chainsaw, take a good look at the tree. Determine its lean, wind direction, and any obstacles that might affect its fall. Identify escape routes in case something goes wrong.
2. Clear the Area: Remove any brush, debris, or obstacles that could trip you or interfere with your swing.
3. Make the Notch: Use your MS 251 C to carefully cut the notch, ensuring it’s the correct size and angle.
4. Make the Back Cut: Start the back cut, leaving the hinge intact.
5. Insert Wedges (If Necessary): For larger trees or trees with a strong lean, use felling wedges to help push the tree over in the desired direction.
6. Watch and Listen: As the tree begins to fall, step back quickly and watch carefully. Be aware of falling branches and any other hazards.

My Personal Experience:

I once underestimated the lean of a tree and ended up with it falling in the wrong direction, narrowly missing my truck. That was a wake-up call. Now, I always take the time to carefully assess the situation before making a single cut.

Expert Insight:

“The hinge is the most critical part of the felling cut,” says veteran logger, Jim Hatfield. “It’s what gives you control. A properly sized and shaped hinge will ensure the tree falls exactly where you want it to.”

Data Point:

According to the Occupational Safety and Health Administration (OSHA), improper felling techniques are a leading cause of logging accidents. Taking the time to learn and practice proper techniques can significantly reduce your risk of injury.

2. Optimizing Bucking Techniques: Maximizing Yield and Minimizing Strain

Once the tree is on the ground, the next step is bucking – cutting the trunk into usable lengths. This is where efficiency and ergonomics come into play. Poor bucking techniques can lead to wasted wood, unnecessary strain on your body, and increased risk of injury.

Understanding Wood Stress:

Wood is a dynamic material that is subject to internal stresses. When bucking, it’s important to understand how these stresses can affect the cut.

• Compression: The top side of a log that is supported at both ends is under compression.
• Tension: The bottom side of a log that is supported at both ends is under tension.

Knowing this helps determine the best way to cut the log to prevent pinching or binding.

The “Golden Rule” of Bucking:

• Cut on the compression side first. This prevents the saw from getting pinched and allows for a clean, safe cut.

Bucking Techniques for Different Situations:

• Log Supported at Both Ends: Cut one-third of the way through from the top (compression side), then finish the cut from the bottom (tension side).
• Log Supported at One End: Cut one-third of the way through from the bottom (tension side), then finish the cut from the top (compression side).
• Log Supported in the Middle: Cut one-third of the way through from the top (compression side), then finish the cut from the bottom (tension side).

Ergonomics and Body Mechanics:

Bucking can be physically demanding, so it’s important to use proper body mechanics to avoid strain and injury.

• Keep Your Back Straight: Bend at your knees and hips, not your back.
• Use Your Legs: Let your legs do the work, not your arms.
• Take Breaks: Don’t try to buck an entire tree in one go. Take frequent breaks to rest and stretch.
• Vary Your Stance: Change your stance periodically to avoid fatigue in any one muscle group.

Using Bucking Aids:

• Bucking Sawhorses: These provide a stable and ergonomic platform for bucking logs.
• Log Lifters: These tools help lift logs off the ground, making them easier to cut.
• Cant Hooks: These are used to roll logs, allowing you to access different sides for cutting.

My Personal Experience:

I used to power through bucking without paying attention to my body mechanics. I ended up with a sore back and aching knees. Now, I take the time to set up properly, use bucking aids, and take frequent breaks. It’s made a huge difference in my comfort and productivity.

Expert Insight:

“Think about the wood before you cut it,” advises arborist, Sarah Jones. “Understanding the stresses in the wood will help you make the right cuts and avoid problems.”

Data Point:

A study by the U.S. Forest Service found that using proper bucking techniques can increase wood yield by up to 15%. This means you get more usable wood from each tree, reducing waste and increasing efficiency.

3. Chainsaw Maintenance: The Key to Longevity and Performance

Your Stihl MS 251 C is a precision machine, and like any machine, it needs regular maintenance to perform at its best. Neglecting maintenance can lead to reduced performance, increased wear and tear, and even premature failure. I’ve seen chainsaws that were practically brand new rendered useless because of poor maintenance. Don’t let that happen to yours.

Chain Sharpening: The Foundation of Efficient Cutting:

A sharp chain is essential for efficient and safe cutting. A dull chain will cause the saw to work harder, increasing fuel consumption and wear and tear. It will also be more likely to kick back, which can be dangerous.

• Frequency: Sharpen your chain every time you refuel or when you notice it’s not cutting as well.
• Tools: You can sharpen your chain with a file and guide or with a chain grinder.
• Technique: Maintain the correct angle and depth when sharpening each cutter.
• Checking Sharpness: A sharp chain will pull itself into the wood. A dull chain will require more pressure and produce fine sawdust instead of chips.

Bar Maintenance: Ensuring Smooth Operation:

The bar is the guide for the chain, and it needs to be kept in good condition to ensure smooth operation.

• Cleaning: Regularly clean the bar groove with a scraper or screwdriver to remove dirt and debris.
• Filing: File the bar rails to remove any burrs or damage.
• Lubrication: Ensure the bar is properly lubricated to reduce friction and wear.
• Flipping: Flip the bar periodically to ensure even wear.

Air Filter Maintenance: Protecting the Engine:

A clean air filter is essential for proper engine performance. A dirty air filter will restrict airflow, causing the engine to run lean and overheat.

• Cleaning: Clean the air filter regularly with compressed air or soap and water.
• Replacement: Replace the air filter when it becomes excessively dirty or damaged.

Fuel and Oil: Using the Right Mix:

Using the correct fuel and oil mixture is crucial for engine longevity.

• Fuel: Use fresh, high-quality gasoline with an octane rating of 89 or higher.
• Oil: Use a high-quality two-stroke oil specifically designed for chainsaws.
• Mixing Ratio: Follow the manufacturer’s recommended mixing ratio (usually 50:1).
• Storage: Store fuel in a clean, airtight container and use it within 30 days.

Regular Inspections:

• Check for Loose Parts: Regularly inspect the chainsaw for loose screws, bolts, or other parts.
• Inspect the Chain Brake: Ensure the chain brake is functioning properly.
• Check the Spark Plug: Inspect the spark plug for wear or damage.
• Check the Fuel and Oil Lines: Ensure the fuel and oil lines are in good condition and not leaking.

My Personal Experience:

I used to neglect chainsaw maintenance, thinking it was a waste of time. But I quickly learned that a little maintenance goes a long way. Now, I have a regular maintenance routine, and my chainsaw runs like a champ.

Expert Insight:

“Chainsaw maintenance is like preventative medicine,” says small engine mechanic, Tom Evans. “A little bit of care and attention can save you a lot of trouble down the road.”

Data Point:

A study by Stihl found that regular chainsaw maintenance can extend the life of the saw by up to 50%. This means you can save money by avoiding costly repairs or replacements.
