3 Key Logging Insights: Unleashing the MS460’s Potential
Now, let’s get to the heart of the matter: the three key logging insights that will help you maximize the MS460’s performance and longevity.
1. Chain Selection and Maintenance: The Cutting Edge
The chain is arguably the most crucial component of any chainsaw. A dull or improperly chosen chain will drastically reduce cutting speed, increase fuel consumption, and put unnecessary strain on the engine.
- Chain Type: For professional logging, I recommend using a full-chisel chain with a .375″ pitch and .063″ gauge. Full-chisel chains have square corners that provide aggressive cutting action, making them ideal for felling large trees. However, they are also more prone to damage from dirt and rocks.
- Chain Sharpening: Regular chain sharpening is absolutely essential. I sharpen my chains at least twice a day when felling timber. A sharp chain will cut straight and pull itself through the wood, requiring minimal pressure from the operator. I use a chainsaw file with a guide to ensure consistent sharpening angles (typically 30 degrees for the top plate and 60 degrees for the side plate).
- Depth Gauge Adjustment: The depth gauges (also known as rakers) control how much wood the chain removes with each pass. If the depth gauges are too high, the chain will cut slowly. If they are too low, the chain will be too aggressive and prone to kickback. I use a depth gauge tool to maintain the correct height (typically .025″ below the top plate).
- Chain Tension: Proper chain tension is crucial for safety and performance. The chain should be snug against the bar but still able to be pulled around by hand. Too loose, and the chain can derail. Too tight, and it can overheat and break. I check and adjust the chain tension frequently, especially when the chain is new.
- Bar Maintenance: Don’t neglect the bar! Clean the bar groove regularly to remove sawdust and debris. Flip the bar periodically to ensure even wear. Check the bar rails for burrs or damage and file them smooth.
Case Study: I once worked on a logging project where the crew was experiencing excessive chain breakage. After investigating, I discovered that they were using the wrong type of chain for the wood they were cutting (hardwood with a lot of knots). I recommended switching to a more durable semi-chisel chain, and the problem was immediately resolved. This highlights the importance of selecting the right chain for the job.
Strategic Advantage: A well-maintained chain not only improves cutting performance but also reduces the risk of accidents. A sharp chain is a safer chain.
2. Felling Techniques: Precision and Safety
Felling trees is a dangerous job, and it’s crucial to use proper techniques to ensure your safety and the safety of others. The MS460 is a powerful saw, but it’s only as effective as the person wielding it.
- Planning the Fall: Before making any cuts, carefully assess the tree and its surroundings. Consider the lean of the tree, the wind direction, the presence of obstacles (other trees, power lines, buildings), and the escape route.
- Making the Notch: The notch (or undercut) determines the direction of the fall. It should be cut at a 45-degree angle, with the depth of the notch being approximately 1/5 to 1/3 of the tree’s diameter. I prefer to use an open-face notch, which allows for a wider range of felling angles.
- The Hinge: The hinge is the strip of wood left between the notch and the back cut. It controls the speed and direction of the fall. The hinge should be of uniform thickness and approximately 1/10 of the tree’s diameter.
- The Back Cut: The back cut is made on the opposite side of the tree from the notch, slightly above the apex of the notch. Leave a hinge! Never cut completely through the tree.
- Using Wedges: Wedges are used to help guide the tree’s fall and prevent it from pinching the bar. I always carry several wedges with me when felling timber. Plastic wedges are generally preferred, as they are less likely to damage the chain if accidentally contacted.
- Escape Route: Before making the back cut, clear an escape route at a 45-degree angle away from the direction of the fall. Be aware of your surroundings and watch for falling branches (widowmakers).
My Experience: I once witnessed a near-fatal accident where a logger failed to properly assess the lean of a tree. He made the notch and back cut, but the tree fell in the opposite direction of what he intended, narrowly missing him. This incident reinforced the importance of careful planning and attention to detail when felling trees.
Case Study: In a dense forest with limited space for felling, I utilized a technique called “precision felling.” This involved using a combination of wedges, ropes, and a pulling machine to carefully guide the tree’s fall between other standing trees. This technique requires a high level of skill and experience, but it can be invaluable in situations where space is limited.
Strategic Advantage: Proper felling techniques not only improve safety but also increase efficiency. By controlling the direction of the fall, you can minimize damage to the timber and make it easier to extract.
3. Fuel and Lubrication: Keeping the MS460 Running Smoothly
The MS460 is a two-stroke engine, which means it requires a mixture of gasoline and oil to lubricate the engine’s internal components. Using the correct fuel and oil mixture is critical for preventing engine damage and ensuring long-term reliability.
- Fuel Mixture: STIHL recommends a fuel mixture of 50:1 (gasoline to oil) for the MS460. This means mixing 50 parts gasoline with 1 part two-stroke oil. Always use high-quality two-stroke oil that meets or exceeds the API TC standard. I personally prefer to use STIHL’s Ultra HP two-stroke oil.
- Gasoline: Use fresh, unleaded gasoline with a minimum octane rating of 89. Avoid using gasoline that contains ethanol, as ethanol can damage the engine’s fuel system. If you must use gasoline that contains ethanol, use a fuel stabilizer to prevent the ethanol from absorbing moisture and causing corrosion.
- Chain Oil: Use a high-quality chain oil to lubricate the chain and bar. Chain oil reduces friction, prevents overheating, and prolongs the life of the chain and bar. I recommend using STIHL’s BioPlus chain oil, which is biodegradable and environmentally friendly.
- Air Filter: The air filter prevents dirt and debris from entering the engine. Clean the air filter regularly, especially in dusty conditions. I clean my air filter every day when felling timber.
- Spark Plug: The spark plug ignites the fuel mixture in the engine. Replace the spark plug periodically to ensure optimal engine performance. I replace my spark plug every 100 hours of use.
My Experience: I once neglected to properly mix the fuel for my MS460. I accidentally used too much oil, which caused the engine to run sluggishly and produce excessive smoke. I had to drain the fuel tank and refill it with the correct mixture. This experience taught me the importance of paying close attention to the fuel mixture.
Case Study: In a remote logging operation, access to high-quality gasoline was limited. We had to rely on gasoline that contained ethanol. To mitigate the potential damage, we used a fuel stabilizer and regularly inspected the fuel lines and carburetor for signs of corrosion. We also drained the fuel tank at the end of each day to prevent the ethanol from absorbing moisture overnight.
Strategic Advantage: Proper fuel and lubrication practices not only extend the life of the MS460 but also improve its performance and fuel efficiency. A well-maintained engine will run smoother, produce more power, and consume less fuel.
Beyond the Basics: Advanced Techniques and Considerations
While the three key insights above are fundamental, there are several other factors that can impact the MS460’s performance and your overall logging operation.
Wood Type and Cutting Strategy
The type of wood you’re cutting significantly affects chain wear, cutting speed, and the overall effort required. Hardwoods like oak and maple require sharper chains and more power than softwoods like pine and fir. Knotty wood can also be particularly challenging, increasing the risk of chain kickback.
- Hardwood vs. Softwood: When cutting hardwoods, I use a more aggressive chain and sharpen it more frequently. I also take smaller bites to avoid bogging down the saw.
- Knotty Wood: When cutting knotty wood, I approach the knots at a shallow angle to minimize the risk of kickback. I also use a chain with a lower depth gauge setting to prevent the chain from grabbing.
Bar Length Selection
Choosing the correct bar length is crucial for safety and efficiency. A bar that is too short will limit your reach and require you to bend over more, increasing the risk of back injury. A bar that is too long will make the saw unwieldy and difficult to control.
- General Rule: As a general rule, the bar length should be slightly longer than the diameter of the largest tree you expect to fell.
- My Preference: For the MS460, I typically use a 20″ or 24″ bar for most logging applications.
Personal Protective Equipment (PPE)
Logging is a dangerous profession, and it’s essential to wear appropriate PPE to protect yourself from injury.
- Helmet: A hard hat is essential to protect your head from falling branches and other debris.
- Eye Protection: Safety glasses or a face shield will protect your eyes from sawdust and flying debris.
- Hearing Protection: Earplugs or earmuffs will protect your hearing from the loud noise of the chainsaw.
- Gloves: Gloves will protect your hands from cuts and abrasions.
- Chainsaw Chaps: Chainsaw chaps are designed to stop the chain in the event of a kickback, preventing serious leg injuries.
- Steel-Toed Boots: Steel-toed boots will protect your feet from falling logs and other hazards.
Maintaining Peak Performance: Long-Term Care
Beyond the daily and weekly maintenance, here’s what I do to keep my MS460 roaring for years:
- Winterizing: Before storing the saw for the winter, I drain the fuel tank, clean the carburetor, and lubricate the cylinder with a fogging oil. This prevents corrosion and ensures that the saw will start easily in the spring.
- Professional Servicing: I take my MS460 to a qualified chainsaw mechanic for a tune-up every year. This ensures that the engine is running optimally and that any potential problems are identified and addressed before they become serious.
- Parts Replacement: Don’t hesitate to replace worn or damaged parts. Replacing a worn sprocket or clutch drum can significantly improve the saw’s performance and prevent further damage.
