Echo Chainsaw 20 Inch Bar Guide (5 Expert Tips for Heavy Cutting)

Safety First: Your Gateway to Mastering the Echo Chainsaw and Heavy Cutting

Before we even think about firing up that Echo chainsaw, let’s talk safety. I can’t stress this enough: wood processing, especially with a powerful tool like a chainsaw, demands respect and unwavering focus. The global logging and firewood industry, valued at billions, unfortunately also sees its share of accidents. Statistics show that improper chainsaw use is a leading cause of injury in both professional and amateur settings. We’re talking cuts, lacerations, and even more severe incidents. I want to make sure you’re not a statistic.

I remember early in my wood-cutting days, feeling invincible after a few successful cuts. That’s when complacency creeps in. One slip, one moment of distraction, and you’re facing a serious injury. I learned that lesson the hard way with a nasty gash on my leg from a kickback. Thankfully, I was wearing proper protective gear.

So, let’s gear up – both mentally and physically. This isn’t just a suggestion; it’s the price of admission to this rewarding but potentially dangerous craft.

2024 data from the International Society of Arboriculture highlights that consistent PPE use reduces chainsaw-related injuries by over 80%. Let’s make sure you’re part of that 80%.

Mastering Heavy Cutting with Your Echo Chainsaw: 5 Expert Tips

This guide focuses on maximizing the potential of your 20-inch bar Echo chainsaw for heavy cutting. We’ll delve into techniques that will help you tackle demanding tasks safely and efficiently, whether you’re felling trees, bucking large logs, or preparing firewood for those long winter nights.

Tip #1: The Right Chain Makes All the Difference

The chain is the unsung hero of your chainsaw. It’s the part that actually does the cutting, and choosing the right one can drastically improve performance and safety. I see so many people stick with the factory chain, never realizing the potential they’re missing.

Think of it like tires on your car. You wouldn’t use the same tires for off-roading as you would for highway driving, would you? Chainsaws are the same.

• Types of Chains:

  • Full Chisel: These chains have square-cornered teeth and offer the fastest cutting speed, but they are more prone to kickback and require more skill to use. They’re ideal for experienced users and clean wood.
  • Semi-Chisel: These chains have rounded corners on the teeth, making them more forgiving and less prone to kickback. They’re a good all-around choice for both clean and dirty wood.
  • Low-Profile (Safety) Chains: These chains are designed with features that reduce the risk of kickback. They’re a good choice for beginners or those who prioritize safety.
  • Ripping Chains: These are specifically designed for cutting wood lengthwise (with the grain), like milling lumber. The teeth are angled differently to produce a smoother cut.

• Chain Pitch and Gauge:

  • Pitch: The pitch is the distance between three consecutive rivets on the chain, divided by two. Common pitches include 3/8″ and .325″. You need to match the pitch to your chainsaw’s drive sprocket and bar.
  • Gauge: The gauge is the thickness of the drive links that fit into the groove of the guide bar. Common gauges include .050″ and .058″. Again, you need to match the gauge to your chainsaw and bar.

• My Recommendation: For general heavy cutting with an Echo chainsaw, I recommend a semi-chisel chain with a pitch and gauge that matches your saw. It offers a good balance of cutting speed, durability, and safety. If you’re primarily cutting clean wood and have experience, a full chisel chain can boost your productivity.

• Data Point: Studies have shown that using the correct chain type can increase cutting efficiency by up to 30%. That’s a significant time and energy saver!

• Actionable Tip: Check your chainsaw’s manual to determine the correct pitch and gauge for your saw. Don’t just guess! Then, consider the type of wood you’ll be cutting and choose the appropriate chain type. Always keep a spare chain on hand. I’ve been caught out in the woods with a dull or broken chain more times than I care to admit.

• Personal Story: I once tried to save a few bucks by using a cheap, no-name chain. Big mistake! It dulled quickly, stretched excessively, and eventually broke, sending the chain whipping around. Luckily, I wasn’t injured, but it was a valuable lesson in investing in quality.

Tip #2: Mastering Felling Techniques for Large Trees

Felling a large tree is a serious undertaking that requires careful planning and execution. It’s not something to be taken lightly. I’ve seen too many people attempt it without proper knowledge and end up in dangerous situations.

• Assessing the Tree and Surroundings:

  • Lean: Determine the tree’s natural lean. This will influence the direction it will fall.
  • Wind: Pay attention to the wind direction. Even a slight breeze can affect the fall.
  • Obstacles: Identify any obstacles in the tree’s path, such as other trees, power lines, or buildings.
  • Escape Route: Plan a clear escape route at a 45-degree angle away from the anticipated direction of the fall.

• The Notch (or Face Cut):

  • Purpose: The notch determines the direction of the fall.
  • Types: The most common type is the open-face notch, which provides a wider opening for the tree to fall into.
  • Procedure:
    1. Make the upper cut of the notch at a 45-degree angle, penetrating about 1/5 to 1/3 of the tree’s diameter.
    2. Make the lower cut horizontally, meeting the upper cut to create a wedge-shaped notch.
    3. Remove the wedge.

• The Hinge:

  • Purpose: The hinge controls the fall and prevents the tree from kicking back.
  • Location: The hinge is the uncut wood between the notch and the back cut.
  • Thickness: The hinge should be about 1/10 of the tree’s diameter. Too thin, and the tree may kick back. Too thick, and the tree may not fall cleanly.

• The Back Cut:

  • Purpose: The back cut severs the tree, allowing it to fall.
  • Procedure: Make the back cut horizontally, slightly above the bottom of the notch, leaving the hinge intact.
  • Wedges: Insert felling wedges into the back cut to help push the tree over in the desired direction and prevent the saw from getting pinched.

• Calling “Timber!”: Before the tree begins to fall, shout “Timber!” loudly to warn anyone in the area.

• Data Point: A study by the U.S. Forest Service found that proper felling techniques reduce the risk of accidents by up to 50%.

• Actionable Tip: Practice felling smaller trees before attempting to fell a large one. Consider taking a professional chainsaw safety course. I did, and it was the best investment I ever made in my wood-cutting hobby. Don’t ever underestimate the power of nature, or your chainsaw.

• Personal Story: I once witnessed a near-disaster when a neighbor tried to fell a large oak tree without a proper notch. The tree twisted unexpectedly and nearly landed on his house. It was a close call that could have been avoided with proper planning and technique.

Tip #3: Bucking Large Logs Efficiently and Safely

Bucking is the process of cutting felled trees into smaller, more manageable logs. This is where a 20-inch bar Echo chainsaw really shines.

• Planning Your Cuts:

  • Log Length: Determine the desired length of your logs. Common lengths for firewood are 16 inches, but you may need longer lengths for other purposes.
  • Log Diameter: Consider the diameter of the log. Larger logs may require special techniques.
  • Support: Ensure the log is properly supported to prevent it from pinching the saw.

• Bucking Techniques:

  • Log on the Ground: If the log is lying on the ground, make the first cut about halfway through from the top. Then, roll the log over and finish the cut from the bottom. This prevents the saw from getting pinched.
  • Log Supported at Both Ends: If the log is supported at both ends, make the first cut about halfway through from the bottom. Then, finish the cut from the top.
  • Log Supported at One End: If the log is supported at one end, make the first cut about halfway through from the top. Then, finish the cut from the bottom.
  • Using Bucking Stands: A bucking stand is a metal frame that holds logs securely while you cut them. This is a safer and more efficient way to buck logs.

• Avoiding Pinching:

  • Wedges: Use wedges to keep the cut open and prevent the saw from getting pinched.
  • Relief Cuts: Make relief cuts on the opposite side of the log to relieve tension and prevent pinching.

• Data Point: Using a bucking stand can increase bucking efficiency by up to 40% and reduce the risk of back injuries.

• Actionable Tip: Always keep your chain sharp. A dull chain is more likely to pinch and requires more force to cut, increasing the risk of accidents. I sharpen my chain every time I refuel my saw. It’s a quick and easy way to maintain performance and safety.

• Personal Story: I used to struggle with bucking large logs on the ground. I was constantly getting my saw pinched, and it was exhausting. Then, I invested in a bucking stand. It was a game-changer! It made bucking much easier, faster, and safer.

Tip #4: Splitting Large Logs: Choosing the Right Tools and Techniques

Once you’ve bucked your logs, the next step is splitting them. This can be a challenging task, especially with large logs. Choosing the right tools and techniques is crucial.

• Tool Selection:

  • Splitting Axe: A splitting axe is a heavy axe with a wide head designed for splitting wood. It’s a good choice for smaller logs and those that split easily.
  • Splitting Maul: A splitting maul is a heavier version of the splitting axe, with a heavier head and a longer handle. It’s a good choice for larger logs and those that are more difficult to split.
  • Wedges: Wedges are metal or plastic tools that are driven into cracks in the wood to split it. They’re useful for splitting very large or knotty logs.
  • Sledgehammer: A sledgehammer is used to drive wedges into the wood.
  • Log Splitter: A log splitter is a hydraulic machine that splits logs with a powerful ram. It’s the most efficient and safest way to split large logs.

• Splitting Techniques:

  • Aim for Cracks: Look for existing cracks in the wood and aim for those.
  • Hit the Center: Aim for the center of the log.
  • Use a Wedge: If the log is difficult to split, drive a wedge into a crack and then hit the wedge with a sledgehammer.
  • Rotate the Log: If the log doesn’t split on the first hit, rotate it and try again.

• Safety Precautions:

  • Wear Safety Glasses: Protect your eyes from flying chips of wood.
  • Wear Gloves: Protect your hands from blisters and splinters.
  • Maintain a Safe Distance: Keep bystanders at a safe distance.
  • Use Proper Footwear: Wear sturdy boots with good traction.

• Data Point: A log splitter can split up to 10 times more wood than a splitting axe in the same amount of time.

• Actionable Tip: If you’re splitting a lot of wood, consider renting or buying a log splitter. It will save you time, energy, and reduce the risk of injury. I resisted getting one for years, thinking I could handle it all with an axe. Now, I wouldn’t be without it.

• Personal Story: I once spent an entire weekend trying to split a giant oak log with a splitting axe. I was exhausted, sore, and only managed to split a fraction of the log. The next day, I rented a log splitter and finished the job in a couple of hours. It was a painful but valuable lesson in the importance of using the right tools.

Beyond the Basics: Advanced Techniques and Considerations

Now that we’ve covered the essential tips for heavy cutting with your Echo chainsaw, let’s delve into some advanced techniques and considerations that can further enhance your skills and efficiency.

Understanding Wood Species and Their Properties

Not all wood is created equal. Different wood species have different properties that affect their suitability for various purposes, including firewood, lumber, and construction. Understanding these properties can help you make informed decisions about which wood to use for your projects.

• Hardwoods vs. Softwoods:

  • Hardwoods: Generally denser and heavier than softwoods. They burn longer and produce more heat, making them ideal for firewood. Examples include oak, maple, beech, and ash.
  • Softwoods: Generally less dense and lighter than hardwoods. They burn quickly and produce less heat. Examples include pine, fir, spruce, and cedar.

• Density: Density is a measure of the mass per unit volume of wood. Denser woods are stronger and more durable.

• Moisture Content: Moisture content is the amount of water in the wood, expressed as a percentage of the wood’s dry weight. Green wood has a high moisture content and is difficult to burn. Seasoned wood has a low moisture content and burns easily.

• Heat Value: Heat value is the amount of heat produced when wood is burned. Hardwoods generally have a higher heat value than softwoods.

• Splitting Characteristics: Some woods split easily, while others are more difficult to split. Straight-grained woods tend to split more easily than knotty woods.

• Examples:

  • Oak: A dense hardwood with a high heat value. It’s excellent for firewood but can be difficult to split.
  • Maple: A dense hardwood with a good heat value. It splits easily and is a good all-around choice for firewood.
  • Pine: A softwood with a low heat value. It burns quickly and is best used for kindling.

• Data Point: Oak has a heat value of approximately 28 million BTU per cord, while pine has a heat value of approximately 16 million BTU per cord.

• Actionable Tip: Learn to identify different wood species in your area. This will help you choose the best wood for your projects. I carry a small wood identification guide with me when I’m out in the woods.

Optimizing Firewood Seasoning for Maximum Heat Output

Seasoning firewood is the process of drying it to reduce its moisture content. This is essential for maximizing heat output and reducing smoke.

• Why Season Firewood?

  • Increased Heat Output: Dry wood burns hotter and more efficiently than green wood.
  • Reduced Smoke: Dry wood produces less smoke, which is better for your health and the environment.
  • Easier to Light: Dry wood is easier to light than green wood.
  • Reduced Creosote Buildup: Dry wood produces less creosote, which can build up in your chimney and create a fire hazard.

• Seasoning Methods:

  • Air Drying: The most common method of seasoning firewood is air drying. This involves stacking the wood in a well-ventilated area and allowing it to dry naturally.
  • Kiln Drying: Kiln drying is a faster method of seasoning firewood. It involves placing the wood in a kiln and heating it to remove moisture.

• Air Drying Best Practices:

  • Stacking: Stack the wood in a single row, with gaps between the logs to allow for air circulation.
  • Elevation: Elevate the wood off the ground to prevent moisture from wicking up from the soil.
  • Sunlight: Expose the wood to sunlight to speed up the drying process.
  • Ventilation: Choose a location with good ventilation.
  • Covering: Cover the top of the woodpile to protect it from rain and snow.

• Moisture Content Targets:

  • Ideal Moisture Content: The ideal moisture content for firewood is 20% or less.
  • Testing Moisture Content: You can test the moisture content of firewood with a moisture meter.

• Seasoning Time:

  • Hardwoods: Hardwoods typically take 6-12 months to season.
  • Softwoods: Softwoods typically take 3-6 months to season.

• Data Point: Seasoned firewood can produce up to 50% more heat than green firewood.

• Actionable Tip: Start seasoning your firewood well in advance of the heating season. I start cutting and stacking my firewood in the spring so it has plenty of time to dry before winter.

• Case Study: I conducted a small experiment where I seasoned two piles of oak firewood. One pile was stacked in a sunny, well-ventilated location, and the other was stacked in a shady, poorly ventilated location. After one year, the wood in the sunny location had a moisture content of 15%, while the wood in the shady location had a moisture content of 25%. This demonstrates the importance of proper stacking and ventilation.

Troubleshooting Common Problems

Even with the best preparation and techniques, you may encounter problems while cutting wood. Here are some common problems and how to troubleshoot them:

• Chainsaw Won’t Start:

  • Possible Causes: Empty fuel tank, flooded engine, fouled spark plug, clogged air filter.
