I’ll share personal anecdotes from my own experiences, backed by data and research, to provide you with actionable advice that you can apply immediately. Whether you’re a seasoned logger or a weekend warrior, this guide will help you unlock the full potential of your Stihl MS 310.

The Stihl MS 310: A Reliable Workhorse

Before we dive into bar lengths, let’s appreciate the MS 310. It’s a mid-range chainsaw known for its reliability and versatility. With its 59cc engine, it strikes a balance between power and weight, making it suitable for a wide range of tasks, from felling small to medium-sized trees to bucking firewood. It is important to remember that this machine is not designed for the same work as a professional model, but with proper care and the right setup, it can handle a surprising amount of work.

Understanding Bar Length and Its Impact

The bar length of a chainsaw is the length of the guide bar, measured from the tip to where it enters the saw body. This length dictates the maximum diameter of the wood you can cut in a single pass. However, simply choosing the longest possible bar isn’t always the best strategy.

Why Bar Length Matters

Power and Performance: A longer bar requires more power to drive the chain through the wood. If the bar is too long for the saw’s engine, it can bog down, reducing cutting speed and increasing wear and tear on the engine.
Maneuverability and Control: A shorter bar makes the chainsaw more maneuverable, especially in tight spaces or when limbing branches. Longer bars can be unwieldy and tiring to use for extended periods.
Safety: Using an excessively long bar can increase the risk of kickback, a dangerous phenomenon where the saw suddenly jumps back towards the operator.
Wear and Tear: An improperly matched bar can strain the engine and chain, leading to premature wear and tear on the chainsaw.

The Goldilocks Principle: Finding the “Just Right” Bar Length

The key is to find the “just right” bar length that balances cutting capacity with power and maneuverability. For the Stihl MS 310, the manufacturer recommends bar lengths ranging from 16 to 20 inches. However, the optimal length will depend on the type of wood you’re cutting and your personal preferences.

Pro Tip 1: Consider the Wood Type and Diameter

The type of wood you’re cutting significantly impacts the optimal bar length. Hardwoods like oak, maple, and hickory require more power to cut than softwoods like pine, fir, and cedar. If you primarily cut hardwoods, you may want to stick with a shorter bar (16-18 inches) to maximize the saw’s power.

For softwoods or smaller diameter trees, a longer bar (18-20 inches) can be used without significantly sacrificing performance. I’ve noticed that when processing pine, I can comfortably use an 18-inch bar on my MS 310, but when tackling oak, I prefer the 16-inch bar for better control and power.

Data Point: According to the U.S. Forest Service, hardwoods generally have a density of 40 pounds per cubic foot or higher, while softwoods typically range from 25 to 35 pounds per cubic foot. This difference in density directly impacts the power required to cut through the wood.

Pro Tip 2: Match the Bar to Your Skill Level

Your skill level and experience with chainsaws should also factor into your bar length decision. If you’re a beginner, starting with a shorter bar is generally recommended. Shorter bars are easier to control and less prone to kickback, making them safer for inexperienced users.

As you gain experience and confidence, you can gradually increase the bar length to tackle larger trees. I remember when I first started using a chainsaw, I was intimidated by the longer bars. I started with a 14-inch bar and gradually worked my way up as my skills improved.

Pro Tip 3: Assess Your Typical Cutting Tasks

Consider the types of cutting tasks you typically perform. If you primarily fell trees, a longer bar may be necessary to handle larger diameter trunks. However, if you mainly buck firewood or limb branches, a shorter bar will be more maneuverable and efficient.

For example, if you’re clearing brush and small trees, a 16-inch bar will be ideal. If you’re felling trees with a diameter of 20 inches or more, you’ll need at least an 18-inch bar, but you may want to consider a more powerful chainsaw altogether.

Personal Story: I once tried to fell a large oak tree with a 16-inch bar on my MS 310. It was a struggle, and I ended up having to make multiple cuts from different angles. I learned my lesson that day: it’s better to have a bar that’s slightly too long than one that’s too short.

Pro Tip 4: Consider Chain Type and Sharpness

The type of chain you use and its sharpness also play a crucial role in maximizing the MS 310’s power. A sharp chain will cut through wood much more efficiently than a dull chain, regardless of the bar length.

Chain Types

Full Chisel: These chains have square-cornered teeth that cut aggressively and are best suited for clean wood.
Semi-Chisel: These chains have rounded teeth that are more forgiving in dirty or frozen wood.
Low-Profile: These chains are designed for safety and are less prone to kickback.

I personally prefer using a full chisel chain on my MS 310 when cutting clean hardwoods. However, when cutting firewood that may contain dirt or debris, I switch to a semi-chisel chain to maintain sharpness longer.

Chain Sharpness

A dull chain will not only slow down your cutting speed but also put unnecessary strain on the engine. Make sure to sharpen your chain regularly using a chainsaw file or a chain grinder. I recommend sharpening your chain after every few tanks of gas, or more frequently if you’re cutting dirty or abrasive wood.

Actionable Advice: Invest in a quality chainsaw file and learn how to sharpen your chain properly. There are many online tutorials and videos that can guide you through the process.

Pro Tip 5: Maintain Your Chainsaw Properly

Proper maintenance is essential for maximizing the power and lifespan of your Stihl MS 310, regardless of the bar length you choose. This includes:

Cleaning the Air Filter: A dirty air filter restricts airflow to the engine, reducing power. Clean the air filter regularly with soap and water.
Checking the Spark Plug: A fouled spark plug can cause the engine to run poorly. Replace the spark plug annually or as needed.
Lubricating the Bar and Chain: Proper lubrication reduces friction and wear on the bar and chain. Use a high-quality bar and chain oil and check the oil level frequently.
Adjusting the Carburetor: If the engine is running too lean or too rich, it can affect performance. Consult your owner’s manual for instructions on adjusting the carburetor.

Unique Insights:

Moisture Content Dynamics: The moisture content of wood significantly affects its cutting resistance. Green wood (freshly cut) has a higher moisture content and is generally easier to cut than seasoned wood. However, green wood is also heavier and more prone to warping and cracking as it dries.
Timber Quality: The presence of knots, grain patterns, and defects in the wood can also affect cutting performance. Wood with numerous knots or irregular grain patterns will be more difficult to cut than clear, straight-grained wood.
Fuel Value Ratings: The fuel value of firewood varies depending on the type of wood and its moisture content. Hardwoods generally have a higher fuel value than softwoods. Seasoned wood burns hotter and cleaner than green wood.

Case Study: Optimizing Bar Length for Firewood Processing

I recently undertook a project to process several cords of firewood from a mix of oak and maple trees. I started by using an 18-inch bar on my MS 310, but I quickly realized that it was bogging down in the larger oak logs. I switched to a 16-inch bar, and the saw performed much better.

I also experimented with different chain types. I found that a full chisel chain worked best for the clean oak logs, while a semi-chisel chain was more suitable for the dirtier maple logs.

Cost-Benefit Analysis:
