• MS 500i: With the MS 500i, they can process one cord of wood in 3 hours, totaling 150 hours per year.

This represents a savings of 50 hours per year. If the firewood producer values their time at $30 per hour, this translates to a savings of $1,500 per year. Over several years, the MS 500i can pay for itself through increased productivity alone.

5 Pro Tips for Firewood Pros Using the MS 500i

Now that you understand the specs and costs, let’s dive into the real meat of this article: how to use the MS 500i like a seasoned pro. These tips are based on years of experience in the woods and are designed to help you work smarter, not harder.

Tip #1: Master the Art of the Bore Cut

The bore cut, also known as the plunge cut, is a technique used to fell large trees safely and efficiently. It involves using the tip of the chainsaw bar to bore a hole through the trunk of the tree, creating a hinge that controls the direction of the fall.

Why is the Bore Cut Important?

• Directional Control: The bore cut allows you to precisely control the direction in which the tree falls, minimizing the risk of damage to property or injury to yourself or others.
• Preventing Kickback: By boring into the tree, you reduce the risk of kickback, a dangerous phenomenon that can cause the chainsaw to jump back towards the operator.
• Releasing Tension: The bore cut can be used to release tension in the wood, preventing the bar from getting pinched during the felling process.

How to Perform a Bore Cut with the MS 500i

1. Stance: Establish a stable stance with your feet shoulder-width apart and your weight evenly distributed.
2. Initial Cut: Make a standard felling cut on the side of the tree in the direction you want it to fall. This cut should be about 20% of the tree’s diameter.
3. Bore Cut Entry: Position the tip of the chainsaw bar just behind the felling cut. Engage the chain brake and rev the engine to full throttle.
4. Boring In: Carefully plunge the tip of the bar into the tree, using the lower portion of the bar to guide the cut. Maintain a steady pressure and avoid forcing the saw.
5. Creating the Hinge: Once the bar is fully inserted, pivot the saw to create a hinge of the desired thickness. The hinge should be about 10% of the tree’s diameter.
6. Final Cut: Make the final felling cut from the opposite side of the tree, leaving the hinge intact. As the tree begins to fall, move away to a safe distance.

Safety Considerations

• Always wear appropriate safety gear: This includes a helmet, eye protection, hearing protection, gloves, and chainsaw chaps.
• Be aware of your surroundings: Look for potential hazards such as overhead branches, power lines, and uneven terrain.
• Never perform a bore cut above shoulder height: This increases the risk of losing control of the saw.
• Practice in a safe environment: Before attempting a bore cut on a large tree, practice on smaller logs to get a feel for the technique.

Tip #2: Optimize Your Chain Sharpening Technique

A sharp chain is essential for efficient and safe chainsaw operation. A dull chain not only slows down your work but also increases the risk of kickback and puts unnecessary strain on the engine.

The Importance of Chain Sharpening

• Increased Cutting Speed: A sharp chain cuts through wood more quickly and efficiently, reducing the amount of time and effort required to process logs.
• Improved Safety: A sharp chain is less likely to kick back, reducing the risk of injury.
• Reduced Engine Strain: A sharp chain reduces the amount of strain on the engine, prolonging its lifespan.
• Cleaner Cuts: A sharp chain produces cleaner, more accurate cuts, resulting in less waste and a better-quality end product.

Sharpening Your Chain Like a Pro

1. Use the Right Tools: Invest in a quality chainsaw file, a depth gauge tool, and a file guide.
2. Secure the Saw: Secure the chainsaw in a vise or use a stump vise to hold it steady.
3. File at the Correct Angle: Use the file guide to maintain the correct filing angle, which is typically 30 degrees for most chainsaw chains.
4. File Each Tooth Evenly: File each tooth with the same number of strokes, ensuring that they are all the same length and shape.
5. Lower the Depth Gauges: Use the depth gauge tool to lower the depth gauges to the correct height. This is essential for preventing kickback.
6. Inspect the Chain: After sharpening, inspect the chain for any signs of damage or wear. Replace the chain if necessary.

Pro Tip: I always carry a small chainsaw file with me in the woods. This allows me to touch up the chain as needed, maintaining peak performance throughout the day.

Data-Backed Insights

A study by Oregon Tool found that a properly sharpened chainsaw chain can increase cutting speed by up to 20% compared to a dull chain. The study also found that a sharp chain reduces the risk of kickback by up to 50%.

Tip #3: Master the Art of Wood Species Selection

Not all wood is created equal. Different species of wood have different properties that make them suitable for different purposes. Understanding these properties can help you make informed decisions about which species to use for firewood, construction, or other projects.

Key Wood Properties to Consider

• Density: Density is a measure of the weight of the wood per unit volume. Dense woods burn hotter and longer than less dense woods.
• Moisture Content: Moisture content is the amount of water in the wood, expressed as a percentage of its dry weight. Dry wood burns more efficiently than wet wood.
• Resin Content: Resin content is the amount of resin or sap in the wood. Woods with high resin content tend to burn quickly and produce a lot of smoke.
• Splitting Ease: Splitting ease is a measure of how easily the wood can be split. Some species of wood split easily, while others are notoriously difficult to split.
• Durability: Durability is a measure of the wood’s resistance to decay and insect damage. Some species of wood are naturally durable, while others require treatment to prevent decay.

Common Wood Species and Their Properties

• Oak: Oak is a dense, hardwood that burns hot and long. It is relatively easy to split and has good durability.
• Maple: Maple is another dense hardwood that burns well. It is more difficult to split than oak but has excellent durability.
• Hickory: Hickory is one of the densest hardwoods and burns extremely hot. It is notoriously difficult to split but has exceptional durability.
• Ash: Ash is a medium-density hardwood that burns well and splits easily. It has good durability.
• Pine: Pine is a softwood that burns quickly and produces a lot of heat. It is very easy to split but has poor durability.

Choosing the Right Wood for Firewood

For firewood, you want to choose a dense hardwood with low moisture content and good splitting ease. Oak, maple, hickory, and ash are all excellent choices. Avoid using softwoods such as pine, as they burn too quickly and produce too much smoke.

Pro Tip: Season your firewood for at least six months before burning it. This will allow the moisture content to decrease, resulting in a hotter, more efficient burn.

Case Study: The Great Oak Firewood Experiment

I once conducted an experiment to compare the burning characteristics of different species of wood. I gathered samples of oak, maple, hickory, and pine, all seasoned to the same moisture content. I then burned each sample in a controlled environment and measured the heat output and burn time. The results showed that oak produced the most heat and burned the longest, followed by maple and hickory. Pine produced the least heat and burned the shortest amount of time. This experiment confirmed my belief that oak is the best choice for firewood.
