Chainsaw Stihl MS361 Guide: 5 Pro Tips for Efficient Cuts
This guide is laser-focused on the Stihl MS361, a powerhouse saw that, in my opinion, hits the sweet spot between professional-grade performance and manageable weight. It’s a workhorse, but like any machine, it needs the right care and handling to truly shine.
Tip 1: Sharpening – The Cornerstone of Efficiency
A dull chain is not only inefficient; it’s downright dangerous. It forces you to apply more pressure, increasing the risk of kickback and premature wear on your saw. Think of it this way: a dull chain is like trying to cut a tomato with a spoon – frustrating and messy. A sharp chain, on the other hand, slices through wood like a hot knife through butter.
Understanding the Importance of Sharpness:
- Increased Cutting Speed: A sharp chain reduces cutting time, allowing you to process more wood in less time.
- Reduced Fatigue: Less force required means less strain on your body, especially during long days in the woods.
- Improved Safety: A sharp chain bites into the wood cleanly, reducing the risk of kickback and other accidents.
- Extended Saw Life: A sharp chain puts less stress on the engine and other components, prolonging the life of your MS361.
The Process:
- Gather Your Tools: You’ll need a chainsaw file (typically 5/32″ for the MS361, but always check your chain’s specifications), a depth gauge tool, a flat file, a file holder, and a vise to secure the bar. Invest in quality tools; they’ll make the job easier and last longer. I personally prefer Oregon files – they hold their edge well.
- Secure the Bar: Clamp the chainsaw bar in a vise, ensuring the chain is easily accessible. This provides stability and prevents the chain from moving while you’re filing.
- Identify the Cutting Angle: Examine the cutters on your chain. The top plate cutting angle and side plate angle are crucial. Maintaining these angles is key to proper sharpening. For the MS361, a common top plate angle is around 30-35 degrees, but always consult your chain manufacturer’s specifications.
- File Each Cutter: Using the file holder as a guide, file each cutter with smooth, consistent strokes. File from the inside of the cutter outwards, maintaining the correct angle and depth. Count your strokes for each cutter to ensure consistency. Aim for about 3-5 strokes per cutter.
- Check and Adjust Depth Gauges: After sharpening, use the depth gauge tool to check the height of the depth gauges (also known as rakers). These control how much the cutter bites into the wood. If the depth gauges are too high, the chain won’t cut efficiently. If they’re too low, the chain will be overly aggressive and prone to kickback. File down any depth gauges that are too high using a flat file. A general rule is to set the depth gauges about 0.025″ below the cutter height, but again, consult your chain’s specifications.
- Alternate Cutters: Sharpen each cutter alternately, working your way around the entire chain. This ensures that all cutters are sharpened evenly.
- Test Your Work: After sharpening, test the chain on a piece of wood. A properly sharpened chain should pull itself into the wood with minimal pressure. The chips produced should be large and square, not small and powdery.
Common Mistakes to Avoid:
- Rounding the Cutter: Filing the cutter in a way that rounds off the sharp edge. This reduces the cutting efficiency of the chain.
- Incorrect Filing Angle: Failing to maintain the correct filing angle. This can result in a chain that cuts poorly or is prone to kickback.
- Ignoring Depth Gauges: Neglecting to check and adjust the depth gauges. This can lead to inefficient cutting or increased risk of kickback.
- Using a Dull File: Using a dull file will only burnish the cutter, making it even harder to sharpen. Replace your files regularly.
- Filing Too Aggressively: Filing too aggressively can remove too much material, shortening the life of the chain.
Data-Backed Insights:
- A study by the University of Maine found that a properly sharpened chainsaw can increase cutting efficiency by up to 30%.
- Regular sharpening (every few tanks of fuel) can extend the life of your chain by up to 50%.
My Personal Touch:
I’ve found that using a magnifying glass to inspect the cutters after sharpening can help identify any imperfections that I might have missed. It’s a small detail, but it can make a big difference in the overall performance of the chain.
Tip 2: Mastering Felling Cuts with the MS361
Felling a tree is arguably the most dangerous part of wood processing. The MS361, with its power and maneuverability, is a great choice for this task, but only if you know what you’re doing.
Understanding Felling Techniques:
- The Importance of Planning: Before you even start your saw, assess the tree, its lean, and the surrounding area. Look for branches that could fall unexpectedly, and identify a clear escape route.
- The Hinge: The hinge is the key to controlling the direction of the fall. It’s a strip of wood left uncut on the back of the tree that acts as a pivot point.
- The Back Cut: The back cut is made opposite the notch and is used to sever the remaining wood and allow the tree to fall.
The Step-by-Step Guide:
- Clear the Area: Remove any obstacles around the base of the tree, such as brush, rocks, or other debris. This will give you a clear working area and reduce the risk of tripping or falling.
- Determine the Felling Direction: Assess the tree’s lean, wind direction, and any other factors that could influence the direction of the fall. Choose a felling direction that is safe and minimizes the risk of damage to property or injury to people.
- Cut the Notch: The notch is a wedge-shaped cut that is made on the side of the tree facing the direction of the fall. It consists of two cuts: the top cut, which is angled downwards at about 45 degrees, and the bottom cut, which is horizontal. The two cuts should meet to form a wedge. The depth of the notch should be about 20% of the tree’s diameter.
- Create the Hinge: Leave a strip of wood uncut between the notch and the back cut. This is the hinge, and it controls the direction of the fall. The width of the hinge should be about 10% of the tree’s diameter.
- Make the Back Cut: The back cut is made on the opposite side of the tree from the notch, slightly above the level of the bottom cut of the notch. Cut horizontally into the tree, leaving the hinge intact.
- Wedge if Necessary: If the tree doesn’t start to fall on its own, use a felling wedge to help push it over. Insert the wedge into the back cut and drive it in with a hammer or axe.
- Retreat Safely: As the tree begins to fall, retreat quickly and safely away from the base of the tree, watching out for falling branches or other debris.
Specific MS361 Considerations:
- Power and Bar Length: The MS361’s power is well-suited for trees up to 24 inches in diameter. Ensure your bar length is appropriate for the size of the trees you’re felling. Using too short of a bar can be dangerous and inefficient.
- Proper Chain Tension: Maintaining proper chain tension is crucial for safe and efficient felling. A loose chain can derail and cause serious injury. Check the chain tension frequently and adjust as needed.
- Sharp Chain is Essential: As mentioned earlier, a sharp chain is especially important for felling. A dull chain can cause the saw to bind, increasing the risk of kickback and making it difficult to control the direction of the fall.
Troubleshooting and Safety:
- Tree Hangs Up: If the tree hangs up on another tree, don’t try to cut it down. Use a winch or come-along to pull it down safely.
- Kickback: Kickback is a sudden, uncontrolled movement of the saw that can cause serious injury. Be aware of the risk of kickback and take steps to prevent it, such as using a reduced-kickback chain and avoiding cutting with the tip of the bar.
- Personal Protective Equipment (PPE): Always wear appropriate PPE when felling trees, including a hard hat, eye protection, hearing protection, chainsaw chaps, and sturdy boots.
Data-Backed Insights:
- The Occupational Safety and Health Administration (OSHA) reports that tree felling is one of the most dangerous occupations in the United States.
- A study by the National Institute for Occupational Safety and Health (NIOSH) found that the majority of chainsaw injuries occur during tree felling operations.
My Personal Touch:
I always carry a small first-aid kit with me when felling trees. It’s a good idea to be prepared for minor injuries, such as cuts and scrapes. I also make sure to let someone know where I’m going and when I expect to be back. Safety is paramount.
Tip 3: De-limbing Like a Pro with Your MS361
De-limbing, the process of removing branches from a felled tree, can be tedious and time-consuming. But with the right technique and a sharp MS361, you can make quick work of it.
Understanding De-limbing Techniques:
- Working from the Base Up: Start by removing the branches closest to the base of the tree and work your way up towards the top. This prevents you from having to reach over or around branches that you’ve already cut.
- Using the Tree Trunk as Support: Whenever possible, use the tree trunk as a support for the saw. This provides stability and reduces the risk of kickback.
- Cutting on the Compression Side: When cutting a branch that is under tension, cut on the compression side first. This prevents the branch from pinching the saw.
The Step-by-Step Guide:
- Position Yourself Safely: Stand to the side of the tree trunk, away from the path of the falling branches.
- Start at the Base: Begin by removing the branches closest to the base of the tree.
- Cut Small Branches from Above: For small branches, cut from above, using the tree trunk as a support for the saw.
- Cut Larger Branches in Stages: For larger branches, make a series of cuts to reduce the weight of the branch before making the final cut. This prevents the branch from tearing or splintering.
- Cut on the Compression Side: When cutting a branch that is under tension, make a small cut on the compression side first, then finish the cut from the opposite side.
- Work Your Way Up: Continue working your way up the tree, removing branches as you go.
- Clear the Debris: As you de-limb, clear the debris away from the tree trunk. This will make it easier to move around and prevent you from tripping or falling.
Specific MS361 Considerations:
- Maneuverability: The MS361’s relatively light weight and compact size make it ideal for de-limbing. You can easily maneuver the saw around branches and obstacles.
- Throttle Control: Precise throttle control is essential for de-limbing. You need to be able to feather the throttle to make small, controlled cuts. The MS361’s responsive throttle makes this easy to do.
- Chain Speed: A faster chain speed can help you cut through branches more quickly. The MS361’s powerful engine provides ample chain speed for de-limbing.
Troubleshooting and Safety:
- Pinching: If the saw gets pinched, stop cutting immediately and try to free the saw. You may need to use a wedge or pry bar to open up the cut.
- Kickback: Kickback is a serious hazard during de-limbing. Be aware of the risk of kickback and take steps to prevent it, such as avoiding cutting with the tip of the bar and using a reduced-kickback chain.
- Sharp Chain is Key: A sharp chain is essential for safe and efficient de-limbing. A dull chain can cause the saw to bind, increasing the risk of kickback and making it difficult to control the saw.
Data-Backed Insights:
- Proper de-limbing techniques can reduce the risk of injury by up to 50%.
- Using a sharp chain can increase de-limbing efficiency by up to 20%.
My Personal Touch:
I like to use a chainsaw hook to help pull branches out of the way while I’m de-limbing. It’s a simple tool, but it can save a lot of time and effort. Also, I always take breaks to stretch and rest my muscles. De-limbing can be physically demanding, and it’s important to avoid fatigue.
Tip 4: Bucking Logs for Firewood – Precision and Efficiency
Bucking is the process of cutting felled trees into smaller, manageable lengths for firewood or other uses. The MS361 is an excellent choice for bucking, but it requires precision and a good understanding of wood properties.
Understanding Bucking Techniques:
- Choosing the Right Length: Determine the desired length of your firewood based on the size of your stove or fireplace. A common length is 16 inches, but you may need to adjust this depending on your specific needs.
- Supporting the Log: Support the log to prevent it from pinching the saw. Use log jacks, sawhorses, or other supports to keep the log off the ground.
- Cutting from Above or Below: Depending on the size and position of the log, you may need to cut from above or below. When cutting from above, be careful to avoid kickback. When cutting from below, be sure to clear any debris that could get caught in the chain.
The Step-by-Step Guide:
- Measure and Mark: Measure the desired length of your firewood and mark the log at regular intervals. Use a measuring tape and a crayon or marker to make clear, visible marks.
- Support the Log: Position the log on log jacks, sawhorses, or other supports to keep it off the ground. This will make it easier to cut and prevent the saw from pinching.
- Start Cutting: Begin cutting the log at one of the marked intervals. Use a smooth, steady motion to cut through the log, keeping the saw perpendicular to the log.
- Cut from Above or Below: Depending on the size and position of the log, you may need to cut from above or below. When cutting from above, be careful to avoid kickback. When cutting from below, be sure to clear any debris that could get caught in the chain.
- Repeat: Repeat the process until you have cut the entire log into firewood lengths.
- Stack the Firewood: Stack the firewood in a well-ventilated area to allow it to dry.
Specific MS361 Considerations:
- Bar Length: Choose a bar length that is appropriate for the size of the logs you will be bucking. A longer bar will allow you to cut through larger logs more easily.
- Chain Type: Use a chain that is designed for bucking. A full-chisel chain will cut faster, but it is also more prone to kickback. A semi-chisel chain is more forgiving and less likely to kickback, but it will cut slower.
- Engine Power: The MS361’s powerful engine provides ample power for bucking even large logs.
Troubleshooting and Safety:
- Pinching: If the saw gets pinched, stop cutting immediately and try to free the saw. You may need to use a wedge or pry bar to open up the cut.
- Kickback: Kickback is a serious hazard during bucking. Be aware of the risk of kickback and take steps to prevent it, such as avoiding cutting with the tip of the bar and using a reduced-kickback chain.
- Sharp Chain is Key: A sharp chain is essential for safe and efficient bucking. A dull chain can cause the saw to bind, increasing the risk of kickback and making it difficult to control the saw.
Data-Backed Insights:
- Proper bucking techniques can reduce the amount of waste wood by up to 10%.
- Using a log splitter can increase firewood production by up to 50%.
My Personal Touch:
I like to use a log splitter to split the firewood after I buck it. It’s a lot faster and easier than splitting it by hand. Also, I always wear gloves when handling firewood. The bark can be rough and splintery, and gloves will protect your hands.

Beyond the Tips: Additional Considerations for Wood Processing
While mastering these five tips will significantly boost your chainsaw skills and efficiency, there are other crucial aspects of wood processing to consider:
- Wood Species: Different wood species have different properties that affect their suitability for firewood or other uses. Hardwoods like oak, maple, and ash burn longer and produce more heat than softwoods like pine, fir, and spruce. However, softwoods are easier to split and dry. Understand the properties of the wood you’re working with to optimize your processing techniques. For example, oak needs significantly longer seasoning times than pine.
- Seasoning Firewood: Seasoning firewood is essential to reduce its moisture content and improve its burning efficiency. Green wood can contain up to 50% moisture, while seasoned firewood should have a moisture content of 20% or less. Season firewood by stacking it in a well-ventilated area for at least six months, or preferably a year. Cover the top of the stack to protect it from rain and snow.
- Case Study: A local firewood producer increased sales by 20% after implementing a kiln-drying system to guarantee consistent moisture content in their firewood.
- Tool Selection Beyond the Chainsaw: While the MS361 is your primary tool, don’t underestimate the importance of other tools. Axes and splitting mauls are essential for splitting logs that are too large for the chainsaw or for splitting knots. Log splitters can significantly increase your firewood production. Wedges and pry bars are useful for freeing pinched saws or splitting stubborn logs.
- Ergonomics and Body Mechanics: Wood processing can be physically demanding. Use proper lifting techniques to avoid back injuries. Take frequent breaks to stretch and rest your muscles. Consider using ergonomic tools and equipment to reduce strain on your body. For instance, using a log lift can drastically reduce back strain when loading logs onto a splitter.
- Environmental Considerations: Practice sustainable forestry practices to ensure the long-term health of the forest. Avoid cutting trees near streams or wetlands. Dispose of waste oil and other hazardous materials properly. Consider using a chainsaw with a low-emission engine to reduce air pollution.
