Key Concepts: Understanding the Basics

Before diving into the pro tips, let’s clarify some essential concepts:

• Green Wood vs. Seasoned Wood: Green wood refers to freshly cut wood with high moisture content (often above 50%). Seasoned wood, on the other hand, has been dried to a moisture content of 20% or less. Green wood is heavier and harder to split, while seasoned wood is easier to work with and burns more efficiently. I learned this the hard way when I first started prepping firewood. Trying to split green oak with a maul was an exercise in futility!
• Chain Pitch: This refers to the distance between three consecutive rivets on the chain, divided by two. Common pitches are .325″, 3/8″, and .404″. The MS 500i uses a 3/8″ pitch, which is ideal for felling large trees and bucking logs.
• Bar Length: The length of the guide bar determines the maximum diameter of trees you can safely fell. Choosing the right bar length is crucial for both safety and efficiency.
• Bucking: This is the process of cutting a felled tree into smaller, more manageable logs.
• Felling: The act of cutting down a tree.
• Kerf: The width of the cut made by the chainsaw chain.

Pro Tip #1: Master the Art of Chain Selection and Sharpening

The chainsaw chain is the heart of your cutting operation. Choosing the right chain and maintaining its sharpness are crucial for maximizing the MS 500i’s performance.

Chain Selection: Choosing the Right Bite

The MS 500i typically uses a .375″ (3/8″) pitch chain. Within this pitch, you have several options:

• Stihl Rapid Micro (RM): This chain has a semi-chisel cutter, making it more forgiving when cutting dirty wood. It’s a good all-around choice for general woodcutting.
• Stihl Rapid Super (RS): This chain features a full-chisel cutter, providing faster cutting speeds in clean wood. It’s ideal for professional loggers and experienced users.

I personally prefer the Rapid Super (RS) chain for its aggressive cutting action. However, it requires more frequent sharpening and is less tolerant of dirt and debris. When working in areas with sandy or dirty wood, I switch to the Rapid Micro (RM) chain to prolong its lifespan.

Here’s a breakdown of chain selection considerations:

Sharpening: Keeping Your Chain Razor Sharp

A dull chain not only slows down your cutting but also increases the risk of kickback and puts unnecessary strain on the chainsaw engine. Sharpening your chain regularly is essential for safety and efficiency.

Here’s my step-by-step guide to chainsaw chain sharpening:

1. Secure the Chainsaw: Place the chainsaw in a vise or secure it on a stump to prevent movement.
2. Inspect the Chain: Look for damaged or broken teeth. Replace the chain if necessary.
3. Use the Correct File: Use a round file with the correct diameter for your chain’s pitch (typically 5/32″ or 7/32″ for a 3/8″ pitch chain).
4. Maintain the Correct Angle: Hold the file at the correct angle (typically 30 degrees) relative to the cutter. Use a file guide to ensure consistent sharpening.
5. File Each Cutter Evenly: File each cutter with smooth, even strokes, working from the inside to the outside of the cutter. Make sure to file each cutter the same number of strokes to maintain a consistent cutting edge.
6. Lower the Depth Gauges: Use a flat file and a depth gauge tool to lower the depth gauges (rakers) to the correct height. The depth gauge controls the amount of wood each cutter takes, so it’s crucial to maintain the correct setting.
7. Clean the Chain: Remove any metal filings from the chain with a brush.
8. Lubricate the Chain: Apply chain oil to the chain before using it.

Pro Tip: Invest in a chainsaw chain sharpening kit that includes a file guide, depth gauge tool, and round and flat files. This will make sharpening your chain much easier and more accurate. I have a Granberg File-N-Joint that I find very reliable.

Case Study: I once worked on a logging project where the crew was constantly struggling with dull chains. After implementing a regular sharpening schedule and training the crew on proper sharpening techniques, we saw a significant increase in productivity and a reduction in chainsaw maintenance costs. The simple act of keeping the chains sharp made a world of difference.

Pro Tip #2: Optimize Fuel and Oil for Peak Performance

The Stihl MS 500i’s electronically controlled fuel injection system is designed to optimize fuel consumption and engine performance. However, using the right fuel and oil is still crucial for maximizing its lifespan and efficiency.

Fuel: Unleaded Gasoline and Two-Stroke Oil

The MS 500i requires a mixture of unleaded gasoline and two-stroke oil. Stihl recommends using a high-quality two-stroke oil specifically designed for air-cooled engines.

• Fuel-to-Oil Ratio: The recommended fuel-to-oil ratio is 50:1 (50 parts gasoline to 1 part oil).
• Gasoline Octane Rating: Use unleaded gasoline with a minimum octane rating of 89 AKI (Anti-Knock Index).
• Stihl MotoMix: Consider using Stihl MotoMix, a pre-mixed fuel and oil blend that is specifically formulated for Stihl engines. MotoMix offers several advantages, including extended storage life and improved engine performance.

Warning: Never use straight gasoline or an incorrect fuel-to-oil ratio. This can cause serious engine damage.

Oil: Chain and Bar Lubrication

Proper chain and bar lubrication is essential for reducing friction and preventing premature wear. Stihl recommends using a high-quality chain oil specifically designed for chainsaws.

• Stihl BioPlus Chain Oil: This is a biodegradable chain oil that is environmentally friendly and provides excellent lubrication.
• Regular Chain Oil: Standard chain oil is also acceptable, but ensure it is designed for chainsaw use.

Pro Tip: Adjust the oiler on the MS 500i to ensure adequate lubrication. The oiler setting should be adjusted based on the type of wood you are cutting and the length of the guide bar.

Experience: I once neglected to check the oil level in my chainsaw, and the chain quickly overheated and seized. This resulted in a damaged chain and bar, as well as a costly repair. I learned my lesson the hard way: always check the oil level before each use and adjust the oiler as needed.

Pro Tip #3: Mastering Felling Techniques for Safety and Efficiency

Felling trees is a dangerous task that requires proper training and technique. The MS 500i’s power and responsiveness make it an excellent tool for felling, but it’s essential to use it safely and effectively.

Assessing the Tree and Surroundings

Before felling any tree, take the time to assess the tree and its surroundings.

• Tree Lean: Determine the direction of the tree’s natural lean.
• Wind Direction: Consider the wind direction and its potential impact on the tree’s fall.
• Obstacles: Identify any obstacles that could interfere with the tree’s fall, such as power lines, buildings, or other trees.
• Escape Routes: Plan your escape routes in advance. You should have two clear escape routes that are at a 45-degree angle away from the expected direction of the fall.

Felling Cuts: The Notch and the Back Cut

The standard felling technique involves two primary cuts: the notch and the back cut.

1. The Notch: The notch is a wedge-shaped cut that determines the direction of the tree’s fall. It should be cut on the side of the tree facing the desired direction of fall.
   • Open Face Notch: This is the most common type of notch, consisting of a horizontal cut and an angled cut that meet at a point. The angle of the notch should be approximately 45 degrees.
   • Humboldt Notch: This notch is cut in an inverted V shape. It is typically used for larger trees or trees with a significant lean.
2. The Back Cut: The back cut is made on the opposite side of the tree from the notch. It should be cut slightly above the horizontal cut of the notch, leaving a hinge of wood to control the tree’s fall.
   • Hinge Wood: The hinge wood is a critical component of the felling process. It acts as a pivot point, allowing you to control the direction and speed of the tree’s fall. The width of the hinge wood should be approximately 10% of the tree’s diameter.

Felling Wedges: Ensuring a Controlled Fall

Felling wedges are used to help direct the tree’s fall and prevent the saw from becoming pinched in the back cut.

• Plastic Wedges: These are the most common type of felling wedge. They are lightweight and durable.
• Aluminum Wedges: These wedges are stronger than plastic wedges and are ideal for larger trees.

Pro Tip: Use multiple felling wedges to ensure a controlled fall. Insert the wedges into the back cut after making the initial cut. As you continue to deepen the back cut, tap the wedges with a hammer to lift the tree in the desired direction.

Safety First: Always wear appropriate safety gear when felling trees, including a helmet, eye protection, hearing protection, gloves, and chainsaw chaps.

Case Study: I once witnessed a near-fatal accident when a logger attempted to fell a large tree without using felling wedges. The tree leaned unexpectedly, pinching the saw and causing the tree to fall in the wrong direction. Fortunately, no one was seriously injured, but the incident served as a stark reminder of the importance of using proper felling techniques.

Pro Tip #4: Optimizing Bucking Techniques for Efficient Log Processing

Bucking is the process of cutting a felled tree into smaller, more manageable logs. The MS 500i’s power and maneuverability make it an excellent tool for bucking, but it’s essential to use efficient techniques to maximize productivity.

Assessing the Log

Before bucking any log, take the time to assess its condition.

• Tension and Compression: Identify areas of tension and compression within the log. Tension occurs on the side of the log that is being stretched, while compression occurs on the side that is being compressed.
• Obstacles: Look for any obstacles that could interfere with the bucking process, such as rocks, branches, or other logs.

Bucking Cuts: Relieving Tension and Preventing Pinching

The key to efficient bucking is to relieve tension and prevent the saw from becoming pinched in the cut.

• Cutting on the Tension Side: When bucking a log that is supported at both ends, start by cutting on the tension side. This will relieve the tension and prevent the log from splitting.
• Cutting on the Compression Side: When bucking a log that is supported in the middle, start by cutting on the compression side. This will prevent the log from pinching the saw.

Bucking Techniques:

• Log Supported at Both Ends: Make a partial cut on the tension side, then roll the log over and complete the cut on the compression side.
• Log Supported in the Middle: Make a partial cut on the compression side, then roll the log over and complete the cut on the tension side.
• Log Suspended: Use a support or log jack to lift the log off the ground before bucking. This will prevent the saw from becoming pinched.

Pro Tip: Use a log jack to lift the log off the ground. This will make bucking much easier and safer.

Experience: I once spent an entire day struggling to buck a large log that was supported at both ends. The saw kept getting pinched, and I was constantly fighting the weight of the log. After switching to a log jack, I was able to buck the remaining logs in a fraction of the time. The log jack made a huge difference in my productivity and reduced my fatigue significantly.
