The MS 361 is known for its durability and ease of maintenance, but like any tool, it performs best when you know how to use it correctly. So, let’s get to those pro hacks.

Hack #1: Mastering the Art of Chain Sharpening

A dull chain is a dangerous chain. It forces you to push harder, increasing the risk of kickback and making the job much more tiring. I’ve seen firsthand how a sharp chain can drastically improve cutting efficiency and safety.

• The Importance of Sharpness: A sharp chain bites into the wood cleanly, producing nice, even chips. A dull chain, on the other hand, creates sawdust and requires excessive force.
• Tools You’ll Need:
  • Chainsaw File: Correct size for your chain (usually 5/32″ or 3/16″). Check your chain specs!
  • File Holder: Helps maintain the correct angle and depth.
  • Depth Gauge Tool: To file down the rakers (depth gauges) when needed.
  • Vise: To securely hold the bar while sharpening.
• Sharpening Technique:
  1. Secure the Bar: Place the chainsaw bar in the vise, ensuring the chain is accessible.
  2. Identify the Correct Angle: Most chains have markings indicating the correct filing angle (typically 25-30 degrees). Use the file holder as a guide.
  3. File Each Cutter: File each cutter from the inside out, using smooth, consistent strokes. Aim for the same number of strokes on each cutter to maintain even sharpness. I usually do 3-5 strokes per cutter.
  4. Check the Depth Gauges (Rakers): Use the depth gauge tool to check the height of the rakers. If they’re too high, file them down slightly. Refer to your chain manufacturer’s specifications for the correct raker height.
• Frequency: I recommend sharpening your chain every few tanks of gas, or whenever you notice a decrease in cutting performance. Don’t wait until it’s completely dull!
• Common Mistakes to Avoid:
  • Filing at the Wrong Angle: This will ruin the cutting edge.
  • Over-Filing: Removing too much material weakens the cutter.
  • Ignoring the Depth Gauges: Improper raker height can cause the chain to chatter or grab.
• Original Insight: I’ve found that using a chainsaw file guide with a roller makes maintaining the correct angle much easier, especially for beginners. It’s a small investment that can save you a lot of time and frustration.
• Measurement: Measure the raker height with a depth gauge tool, ensuring it meets the manufacturer’s specifications (typically around 0.025″ to 0.030″).
• Wood Type Specification: Softer woods like pine require more frequent sharpening than hardwoods like oak.
• Tool List: Chainsaw file, file holder, depth gauge tool, vise.

Takeaway: A sharp chain is essential for safety and efficiency. Learn to sharpen your chain regularly and invest in quality sharpening tools.

Hack #2: Optimizing Fuel and Oil Mix for Peak Performance

The Stihl MS 361, like most two-stroke engines, requires a precise mixture of fuel and oil to run smoothly and prevent damage. Getting this right is crucial for the longevity of your saw.

• The Importance of the Correct Mix: Too little oil can lead to engine seizure, while too much oil can cause excessive smoking and carbon buildup.
• Recommended Ratio: Stihl typically recommends a 50:1 fuel-to-oil ratio for the MS 361. This means 50 parts gasoline to 1 part two-stroke oil. Always refer to your owner’s manual for the exact recommendation.
• Choosing the Right Oil: Use a high-quality two-stroke oil specifically designed for air-cooled engines. Stihl Ultra is a popular choice, but other reputable brands will work as well. Avoid using automotive oil, as it’s not formulated for the high temperatures and demands of a chainsaw engine.
• Mixing Procedure:
  1. Use a Clean Fuel Can: Ensure your fuel can is clean and free of any contaminants.
  2. Add the Correct Amount of Oil: Use a measuring container to accurately measure the oil. For example, for a 1-gallon (3.78 liters) fuel can, you’ll need 2.6 ounces (76 ml) of oil.
  3. Add Gasoline: Fill the can with fresh, high-octane gasoline (89 octane or higher).
  4. Mix Thoroughly: Shake the can vigorously for at least 30 seconds to ensure the oil and gasoline are properly mixed.
• Fuel Storage: Store mixed fuel in a cool, dark place, away from direct sunlight. Use fuel within 30 days for optimal performance. Old fuel can become stale and cause starting problems.
• Common Mistakes to Avoid:
  • Using the Wrong Oil: Automotive oil can damage your engine.
  • Guessing the Ratio: Always measure the oil accurately.
  • Using Old Fuel: Stale fuel can cause starting problems and reduced performance.
• Original Insight: I always add a fuel stabilizer to my mixed fuel, especially if I know I won’t be using it for a while. This helps prevent the fuel from breaking down and keeps the engine running smoothly.
• Measurement: Mix fuel and oil at a 50:1 ratio (50 parts gasoline to 1 part two-stroke oil).
• Tool List: Fuel can, measuring container, two-stroke oil, gasoline, fuel stabilizer (optional).

Takeaway: Using the correct fuel and oil mix is crucial for the performance and longevity of your Stihl MS 361. Always measure accurately and use fresh fuel.

Hack #3: Mastering Felling Cuts for Safety and Efficiency

Felling a tree is one of the most dangerous aspects of woodcutting. Understanding the proper felling cuts is essential for controlling the direction of the fall and minimizing the risk of accidents. I’ve seen too many close calls due to improper felling techniques.

• Assessing the Tree and Surroundings: Before making any cuts, carefully assess the tree’s lean, wind direction, and any obstacles in the area (power lines, buildings, etc.). Plan your escape route.
• Safety Gear: Always wear appropriate safety gear, including a helmet, eye protection, hearing protection, gloves, and chainsaw chaps.
• The Three Essential Cuts:
  1. The Notch Cut: This determines the direction of the fall. It consists of two cuts:
     • The Upper Cut: Made at a 45-degree angle, sloping downwards.
     • The Lower Cut: Made horizontally, meeting the upper cut to create a notch. The notch should be about 1/5 to 1/3 of the tree’s diameter.
  2. The Hinge: This is the uncut wood between the notch and the back cut. It controls the fall of the tree. The hinge should be about 1/10 of the tree’s diameter.
  3. The Back Cut: Made horizontally, slightly above the level of the lower notch cut. Leave the hinge intact.
• Felling Wedges: Use felling wedges to help direct the fall of the tree, especially if it’s leaning in the wrong direction. Insert the wedges into the back cut and hammer them in to lift the tree in the desired direction.
• Communication: If you’re working with a partner, establish clear communication signals before starting the felling process.
• Common Mistakes to Avoid:
  • Cutting Too Deep into the Hinge: This can cause the tree to fall unpredictably.
  • Not Using Felling Wedges: This can make it difficult to control the direction of the fall.
  • Working Alone: Always work with a partner when felling trees.
• Original Insight: I’ve found that using a “bore cut” technique for larger trees can help prevent the tree from pinching the bar during the back cut. This involves boring into the tree from the side, leaving a small amount of wood intact, and then completing the back cut.
• Measurement: The notch should be about 1/5 to 1/3 of the tree’s diameter. The hinge should be about 1/10 of the tree’s diameter.
• Wood Type Specification: The technique remains the same for different wood types, but the force required for felling wedges may vary.
• Tool List: Chainsaw, felling wedges, hammer, measuring tape.

Takeaway: Felling trees is a dangerous task. Master the proper felling cuts and always prioritize safety.

Hack #4: Optimizing Bar and Chain Maintenance for Longevity

Proper bar and chain maintenance is crucial for extending the life of your Stihl MS 361 and ensuring optimal cutting performance. I’ve seen firsthand how neglected bars and chains can lead to costly repairs and reduced efficiency.

• Chain Lubrication: Always use a high-quality bar and chain oil. Keep the oil reservoir full and check the oiler frequently to ensure it’s working properly. A dry chain will quickly overheat and wear out.
• Bar Cleaning: Regularly clean the bar groove to remove sawdust and debris. Use a bar groove cleaner or a small screwdriver. A clogged groove can prevent proper chain lubrication.
• Bar Rail Dressing: Use a bar rail dresser to remove any burrs or damage from the bar rails. This will help prevent the chain from binding and wearing unevenly.
• Chain Tension: Check the chain tension regularly, especially when the chain is new. A properly tensioned chain should have a slight amount of sag on the bottom of the bar.
• Chain Rotation: Rotate the chain on the bar periodically to ensure even wear.
• Bar Flipping: Flip the bar periodically to ensure even wear on both sides.
• Common Mistakes to Avoid:
  • Using the Wrong Oil: Automotive oil is not suitable for bar and chain lubrication.
  • Ignoring Chain Tension: A loose chain can derail and cause damage. A tight chain can overheat and break.
  • Neglecting Bar Cleaning: A clogged bar groove can lead to chain damage.
• Original Insight: I’ve found that using a wire brush to clean the bar and chain after each use helps prevent rust and corrosion, especially in humid environments.
• Equipment Maintenance Schedules: Check chain tension before each use. Clean the bar groove and oiler ports weekly. Dress the bar rails monthly.
• Tool List: Bar and chain oil, bar groove cleaner, bar rail dresser, wire brush.

Takeaway: Regular bar and chain maintenance is essential for extending the life of your Stihl MS 361 and ensuring optimal cutting performance.
