MS361 Chainsaw Tips: 5 Pro Hacks for Efficient Wood Cutting

The Stihl MS361 is a mid-range professional chainsaw that’s earned its stripes in forests and wood yards worldwide. It’s known for its power, reliability, and relatively light weight, making it a favorite for both seasoned professionals and serious homeowners. But even with a top-notch saw like the MS361, optimizing your technique can dramatically improve your efficiency and extend the life of your equipment. These hacks aren’t just about cutting faster; they’re about cutting smarter.

1. Master the Art of Chain Sharpening: Keeping Your Teeth Keen

You know that feeling when you’re trying to cut a tomato with a dull knife? It’s frustrating, inefficient, and potentially dangerous. The same principle applies to your chainsaw. A dull chain forces you to work harder, puts unnecessary strain on the saw, and increases the risk of kickback. I can’t stress this enough: a sharp chain is the single most important factor in efficient wood cutting.

• The Downside of Dull: A dull chain produces sawdust instead of chips, requires more force to cut, overheats the bar and chain, and can lead to dangerous kickback.

• The Upside of Sharp: A sharp chain effortlessly pulls itself through the wood, produces clean chips, reduces strain on the saw, and minimizes the risk of kickback.

• Sharpening Frequency: How often should you sharpen? It depends on the type of wood you’re cutting and how often you’re using the saw. As a general rule, sharpen your chain every time you refuel. If you hit dirt, rocks, or metal, sharpen immediately. You’ll know your chain is dull when you have to apply excessive pressure to make it cut, or if it’s producing fine sawdust instead of chips.

• Sharpening Tools: There are several ways to sharpen a chainsaw chain:

  • Hand Filing: This is the most common method for field sharpening. It requires a round file, a flat file, and a depth gauge tool. It takes practice to master, but it’s a skill worth learning.
  • Electric Chain Sharpeners: These are great for sharpening multiple chains quickly and accurately. They’re more expensive than hand files, but they can save you a lot of time and effort.
  • Professional Sharpening: If you’re not comfortable sharpening your own chain, you can take it to a professional. This is a good option for heavily damaged chains or for ensuring a precise sharpening.

• Sharpening Technique: The key to hand filing is to maintain the correct angle and depth. Use a file guide to ensure consistent sharpening. File each tooth evenly, removing only enough material to restore the cutting edge. Don’t forget to lower the depth gauges after sharpening. Overly high depth gauges will cause the chain to skip and chatter.

  • Data Point: Studies have shown that a properly sharpened chain can increase cutting speed by up to 50% compared to a dull chain.
  • Example: I once spent an entire day struggling to fell a medium-sized oak tree with a dull chain. After finally sharpening the chain, I was able to fell a similar-sized tree in less than half the time.

• Choosing the Right File: Selecting the correct file size is crucial for effective sharpening. The file size depends on the chain pitch, the distance between the rivets on the chain. Your MS361 manual will specify the correct file size for your chain. Using the wrong size file can damage the cutting teeth.

2. Bar and Chain Maintenance: The Foundation of Efficient Cutting

Your chainsaw bar and chain work together as a team. Neglecting one will negatively impact the performance of the other. Proper maintenance will not only extend the life of your bar and chain but also improve your cutting efficiency and safety.

• Bar Maintenance:

  • Cleaning: Regularly clean the bar groove with a screwdriver or bar groove cleaner. Debris buildup in the groove can prevent the chain from running smoothly.
  • Filing: Check the bar rails for burrs and damage. Use a flat file to remove any burrs and restore the rails to a smooth, square profile.
  • Lubrication: Ensure the bar oiler is functioning properly. The chain should be constantly lubricated while cutting. Insufficient lubrication will cause the chain to overheat and wear out prematurely.
  • Flipping: Flip the bar regularly to ensure even wear on both sides. This will help prevent the bar from bending or warping.

• Chain Maintenance:

  • Tensioning: Maintain proper chain tension. A loose chain can derail and cause serious injury. A chain that’s too tight can overheat and damage the bar and sprocket. You should be able to pull the chain away from the bar about 1/8 inch.
  • Lubrication: Use a high-quality bar and chain oil. Avoid using motor oil, as it’s not designed for the high speeds and temperatures of a chainsaw chain.
  • Inspection: Regularly inspect the chain for damage, such as cracked or broken teeth. Replace the chain if it’s severely worn or damaged.

• Choosing the Right Bar and Chain: The bar and chain you select should be appropriate for the type of wood you’re cutting. For hardwoods, you’ll need a more aggressive chain with larger cutters. For softwoods, you can use a less aggressive chain. The bar length should also be appropriate for the size of the trees you’re felling. Using too short a bar can be dangerous, as it can force you to overreach.

  • Data Point: A well-maintained bar and chain can last up to twice as long as a neglected one.
  • Case Study: I once worked on a logging crew where one of the loggers consistently neglected his bar and chain maintenance. He had to replace his bar and chain every few months, while the rest of us were able to get a year or more out of our equipment.

• Understanding Bar Oil: Bar oil isn’t just any lubricant. It’s specifically formulated to cling to the chain at high speeds and temperatures, preventing excessive wear and tear. Using the wrong oil can lead to premature chain failure and damage to the bar.

3. Cutting Techniques: Precision and Safety First

Knowing how to properly operate your MS361 is just as important as having a sharp chain and a well-maintained bar. Proper cutting techniques will not only improve your efficiency but also significantly reduce the risk of accidents.

• Stance and Grip: Maintain a stable stance with your feet shoulder-width apart. Grip the saw firmly with both hands. Keep your thumbs wrapped around the handles.
• Starting the Saw: Always start the saw on the ground. Ensure the chain brake is engaged. Use your foot to secure the saw while pulling the starter cord.

• Felling Techniques:

  • Directional Felling: Plan your fell carefully. Identify the lean of the tree and any obstacles in its path. Use a felling wedge to control the direction of the fall.
  • Notches: Cut a notch on the side of the tree in the direction you want it to fall. The notch should be about one-third of the tree’s diameter.
  • Back Cut: Make a back cut on the opposite side of the tree, slightly above the notch. Leave a hinge of wood to control the fall.
  • Avoiding Pinching: Be aware of the potential for the bar to become pinched in the cut. Use wedges or a felling lever to prevent pinching.

• Limbing Techniques:

  • Working from the Ground: Whenever possible, limb trees from the ground. This is the safest way to limb.
  • Cutting on the Compression Side: When limbing, cut on the compression side of the limb first. This will prevent the bark from tearing.
  • Avoiding Kickback: Be aware of the potential for kickback when limbing. Use the bottom of the bar to cut, and avoid plunging the tip of the bar into the wood.

• Bucking Techniques:

  • Supporting the Log: Support the log to prevent it from pinching the bar. Use wedges or other logs to support the log.
  • Cutting from the Top or Bottom: Determine whether to cut from the top or bottom of the log based on the tension in the wood. If the log is under tension, cut from the top. If the log is under compression, cut from the bottom.

• The Importance of a Clean Work Area: Before you even start your saw, clear the area around the tree. Remove any brush, rocks, or debris that could trip you up or get in the way. A clear work area is a safe work area.

  • Data Point: Studies have shown that proper cutting techniques can reduce the risk of chainsaw accidents by up to 50%.
  • Real-World Example: I once witnessed a logger who was seriously injured because he failed to properly plan his fell. The tree fell in an unexpected direction and struck him.

• Understanding Wood Tension: Wood under tension can snap violently when cut, potentially causing injury. Learn to identify signs of tension, such as bent limbs or leaning trees, and adjust your cutting technique accordingly.

4. Fuel and Oil Management: Keeping Your Saw Running Smoothly

Your MS361 is a precision machine, and it requires the right fuel and oil to run properly. Using the wrong fuel or oil can damage the engine and reduce its performance.

• Fuel:

  • Fuel Type: Use a high-quality, unleaded gasoline with a minimum octane rating of 89.
  • Fuel Mix: Mix the gasoline with a high-quality two-cycle oil at the ratio specified in your owner’s manual (typically 50:1).
  • Fresh Fuel: Use fresh fuel. Gasoline can degrade over time, especially if it’s stored in a hot or humid environment.
  • Fuel Stabilizer: Add a fuel stabilizer to the fuel if you’re not going to use it within a few weeks.

• Oil:

  • Oil Type: Use a high-quality two-cycle oil specifically designed for chainsaws.
  • Oil Ratio: Mix the oil with the gasoline at the ratio specified in your owner’s manual.
  • Bar and Chain Oil: Use a high-quality bar and chain oil to lubricate the bar and chain.

• Proper Storage: Store your fuel and oil in approved containers. Keep the containers away from heat and open flames.

  • Data Point: Using the wrong fuel or oil can reduce the lifespan of your chainsaw engine by up to 50%.
  • Personal Story: I once ruined a chainsaw engine by using a cheap, low-quality two-cycle oil. The engine seized up after only a few hours of use.

• Ethanol’s Impact: Be mindful of ethanol content in gasoline. Ethanol can damage the fuel lines and seals in your chainsaw. If possible, use ethanol-free gasoline or add a fuel stabilizer that’s designed to protect against ethanol damage.

5. Safety Gear: Protecting Yourself from Harm

Chainsaw work is inherently dangerous. It’s crucial to wear the proper safety gear to protect yourself from injury. No matter how experienced you are, accidents can happen.

• Personal Protective Equipment (PPE):

  • Helmet: Wear a helmet with a face shield to protect your head and face from falling debris and kickback.
  • Eye Protection: Wear safety glasses or goggles to protect your eyes from sawdust and flying debris.
  • Hearing Protection: Wear earplugs or earmuffs to protect your hearing from the loud noise of the chainsaw.
  • Gloves: Wear heavy-duty gloves to protect your hands from cuts and abrasions.
  • Chainsaw Chaps: Wear chainsaw chaps to protect your legs from accidental cuts.
  • Steel-Toed Boots: Wear steel-toed boots to protect your feet from falling logs and sharp objects.

• First Aid Kit: Keep a well-stocked first aid kit on hand in case of an accident.

• Emergency Plan: Have an emergency plan in place in case of an accident. Know how to contact emergency services.

  • Data Point: Wearing the proper safety gear can reduce the risk of chainsaw injuries by up to 90%.
  • Critical Insight: Chainsaw chaps are not optional. They’re designed to stop the chain instantly if it comes into contact with your leg, preventing serious injury.

• The Importance of Training: Even with the best safety gear, proper training is essential. Consider taking a chainsaw safety course to learn safe operating procedures and emergency response techniques.

• Beyond the Basics: Don’t forget about less obvious safety considerations, such as staying hydrated and taking breaks to avoid fatigue. Fatigue can impair your judgment and increase the risk of accidents.
