Stihl MS310 Specs: Max Bar Length & Mod Tips (5 Pro Hacks)

The Stihl MS310 is a mid-range chainsaw known for its reliability and power. It’s a favorite among homeowners and professionals alike for its versatility in tackling various wood-cutting tasks.

Understanding the Stihl MS310: A Quick Overview

Before we dive into the nitty-gritty, let’s quickly recap what makes the MS310 a solid choice. It typically features a 59cc engine, providing ample power for felling medium-sized trees, limbing, and bucking firewood. Its robust construction and user-friendly design make it a dependable tool in diverse environments.

Max Bar Length: Finding the Sweet Spot

The recommended maximum bar length for the Stihl MS310 is typically 20 inches. While you might be tempted to go longer, sticking to this recommendation is crucial for several reasons:

• Performance: A longer bar requires more power to drive the chain effectively. Exceeding the recommended length can bog down the engine, reducing cutting speed and efficiency.
• Safety: An excessively long bar can be more difficult to control, increasing the risk of kickback and other accidents.
• Wear and Tear: Overloading the engine with a bar that’s too long can lead to premature wear and tear, shortening the lifespan of your chainsaw.

I remember once trying to push the limits by using a 24-inch bar on my MS310. While it technically “worked,” the performance was noticeably sluggish, and the engine strained significantly. I quickly realized that sticking to the recommended length was the way to go for optimal performance and longevity.

Data Point: Using a 20-inch bar on the MS310 allows you to efficiently cut through logs up to 18 inches in diameter, which covers a significant portion of firewood processing needs.

Choosing the Right Bar Length for Your Needs

While 20 inches is the maximum, you might find that a shorter bar is more suitable for certain tasks. Here’s a quick guide:

• 16-inch Bar: Ideal for limbing, pruning, and cutting smaller firewood. It offers excellent maneuverability and control.
• 18-inch Bar: A good all-around choice for general-purpose cutting, including felling small to medium-sized trees and bucking firewood.
• 20-inch Bar: Best suited for larger trees and logs, providing the reach needed to tackle bigger jobs.

Personal Story: I often switch between an 18-inch and a 20-inch bar depending on the task at hand. For clearing brush and limbing, the 18-inch bar is my go-to. But when I’m processing larger rounds of oak or maple for firewood, the 20-inch bar provides the extra reach I need.

5 Pro Hacks to Maximize Your Stihl MS310’s Performance

Now that we’ve covered bar length, let’s move on to some pro hacks that can help you get the most out of your Stihl MS310. These tips are based on my years of experience and are designed to improve performance, efficiency, and longevity.

Hack #1: Optimize Chain Sharpness and Maintenance

This might seem obvious, but it’s the most crucial aspect of chainsaw performance. A sharp chain cuts faster, smoother, and with less effort, reducing strain on the engine and improving fuel efficiency.

• Sharpen Regularly: I recommend sharpening your chain after every few tanks of fuel, or more often if you’re cutting dirty or abrasive wood.
• Use the Right Tools: Invest in a good quality chainsaw file and a depth gauge tool. Maintaining the correct depth gauge setting is just as important as sharpening the cutters.
• Proper Chain Tension: Ensure your chain is properly tensioned. Too loose, and it can derail; too tight, and it can cause excessive wear on the bar and chain.

Example: I once worked alongside a logger who neglected his chain maintenance. He was constantly struggling to cut through logs, and his chainsaw was overheating. After I showed him how to properly sharpen and maintain his chain, his cutting speed nearly doubled, and his chainsaw ran much smoother.

Data Point: A properly sharpened chain can increase cutting efficiency by up to 50%, saving you time, fuel, and effort.

Hack #2: Upgrade Your Chain

Not all chainsaw chains are created equal. Upgrading to a higher-quality chain can significantly improve cutting performance and durability.

• Consider a Full Chisel Chain: Full chisel chains have square corners and are designed for fast cutting in clean wood. They’re ideal for felling and bucking.
• Opt for a Semi-Chisel Chain: Semi-chisel chains have rounded corners and are more forgiving when cutting dirty or abrasive wood. They’re a good all-around choice for general-purpose cutting.
• Look for Low-Vibration Chains: These chains are designed to reduce vibration, making them more comfortable to use for extended periods.

Case Study: I once switched from a standard chain to a full chisel chain on my MS310 when I was processing a large quantity of pine for a cabin project. The difference in cutting speed was remarkable. I was able to cut through the pine logs much faster and with less effort.

Insight: When selecting a new chain, consider the type of wood you’ll be cutting most often. Softer woods like pine and fir benefit from aggressive full chisel chains, while hardwoods like oak and maple are better suited to semi-chisel chains.

Hack #3: Adjust Carburetor Settings for Optimal Performance

The carburetor regulates the air-fuel mixture in your chainsaw’s engine. Adjusting the carburetor settings can optimize performance for different altitudes, temperatures, and wood types.

• Locate the Adjustment Screws: The carburetor typically has three adjustment screws: L (low speed), H (high speed), and LA (idle speed).
• Start with the Factory Settings: Consult your owner’s manual for the factory settings for your MS310.
• Make Small Adjustments: Adjust the L and H screws in small increments (1/8 turn) to fine-tune the air-fuel mixture.
• Listen to the Engine: The engine should run smoothly and consistently at both low and high speeds. If it’s sputtering or hesitating, adjust the carburetor settings accordingly.
• Adjust Idle Speed: Adjust the LA screw to set the correct idle speed. The chain should not move at idle.

Caution: Incorrect carburetor adjustments can damage your engine. If you’re not comfortable making these adjustments yourself, consult a qualified chainsaw mechanic.

My Experience: I live in a mountainous area, and I’ve found that I need to adjust the carburetor settings on my MS310 slightly to compensate for the higher altitude. This ensures that the engine runs smoothly and efficiently.

Hack #4: Modify the Muffler for Increased Power (with caution)

Modifying the muffler can increase exhaust flow, which can, in turn, increase engine power. However, this modification should be approached with caution, as it can also increase noise levels and potentially void your warranty.

• Understand the Risks: Modifying the muffler can make your chainsaw louder and may not be legal in all areas. It can also affect the engine’s performance and longevity if not done correctly.
• Consider a Muffler Mod Kit: If you’re not comfortable modifying the muffler yourself, you can purchase a muffler mod kit that’s specifically designed for the Stihl MS310.
• Enlarge the Exhaust Port: The most common muffler modification involves enlarging the exhaust port to increase exhaust flow.
• Add an Additional Exhaust Port: Another option is to add an additional exhaust port to the muffler.

Important Considerations:

• Noise Levels: Be mindful of noise levels when modifying your muffler. Excessive noise can be disruptive to neighbors and may violate local noise ordinances.
• Spark Arrestor: Ensure that your modified muffler still includes a spark arrestor to prevent wildfires.
• Engine Tuning: After modifying the muffler, you may need to adjust the carburetor settings to compensate for the increased exhaust flow.

Ethical Note: I always check local regulations and consider the impact on my neighbors before modifying my muffler. Responsible chainsaw use is paramount.

Data Point: A well-executed muffler modification can increase engine power by up to 10%, but it’s crucial to weigh the benefits against the potential risks.

Hack #5: Use High-Quality Fuel and Oil

Using high-quality fuel and oil is essential for maintaining the performance and longevity of your Stihl MS310.

• Use Fresh Fuel: Gasoline can degrade over time, so it’s important to use fresh fuel. I recommend using fuel that’s less than 30 days old.
• Use the Correct Octane Rating: Consult your owner’s manual for the recommended octane rating for your MS310.
• Use a Fuel Stabilizer: If you’re not going to use your chainsaw for an extended period, add a fuel stabilizer to the fuel tank to prevent fuel degradation.
• Use High-Quality Two-Stroke Oil: Use a high-quality two-stroke oil that’s specifically designed for air-cooled engines.
• Mix Fuel and Oil Correctly: Mix the fuel and oil according to the manufacturer’s recommendations. Using the wrong fuel-oil ratio can damage your engine.

Personal Experience: I once used low-quality fuel in my MS310, and it caused the engine to run poorly and eventually seize up. I learned my lesson the hard way and now only use high-quality fuel and oil.

Wood Species Insight: Consider the wood you are cutting; some species have oils that can affect the fuel system over time. Regularly cleaning the fuel filter and carburetor is especially important when processing oily wood like certain types of cedar.

Actionable Tip: Always drain the fuel tank before storing your chainsaw for an extended period. This prevents fuel from degrading and causing problems with the carburetor.

Wood Processing Techniques for Efficiency and Safety

Beyond maximizing your chainsaw’s performance, efficient and safe wood processing techniques are crucial. Here are some best practices I’ve learned over the years:

Proper Felling Techniques

Felling a tree safely and efficiently requires careful planning and execution.

• Assess the Tree: Before felling a tree, assess its size, lean, and any potential hazards, such as dead branches or power lines.
• Plan Your Escape Route: Plan a clear escape route that’s at a 45-degree angle away from the direction of the fall.
• Make a Notch Cut: Make a notch cut on the side of the tree facing the direction you want it to fall. The notch should be about 1/3 of the tree’s diameter.
• Make a Back Cut: Make a back cut on the opposite side of the tree, slightly above the notch cut. Leave a hinge of wood to control the direction of the fall.
• Use Wedges: If necessary, use wedges to help guide the tree’s fall.

Safe Limbing Practices

Limbing involves removing branches from a felled tree.

• Work from the Base to the Top: Start limbing at the base of the tree and work your way towards the top.
• Stand on the Opposite Side of the Branch: When limbing, stand on the opposite side of the branch you’re cutting to avoid being hit by falling branches.
• Use a Lever: Use a lever to lift branches off the ground before cutting them.
• Be Aware of Spring Poles: Be aware of spring poles, which are branches that are under tension. These branches can snap back violently when cut.

Efficient Bucking Methods

Bucking involves cutting a felled tree into shorter lengths.

• Plan Your Cuts: Before bucking a tree, plan your cuts to maximize yield and minimize waste.
• Use a Measuring Tool: Use a measuring tool to ensure that your cuts are accurate.
• Support the Log: Support the log on sawhorses or other supports to prevent it from pinching the chain.
• Use a Bucking Bar: Use a bucking bar to prevent the log from rolling.

Real Example: I once helped a friend buck a large oak tree that had fallen in his yard. We carefully planned our cuts to maximize the amount of firewood we could get from the tree. We used sawhorses to support the log and a bucking bar to prevent it from rolling. We were able to buck the entire tree into firewood in a single afternoon.
