545 Husqvarna Chainsaw CC Upgrades (5 Pro Tips for Firewood Cutting)

Okay, let’s dive into upgrading your Husqvarna 545 chainsaw for optimal firewood cutting. I’ll share my personal experiences and insights, along with detailed instructions and professional tips to help you get the most out of your saw.

Introduction: Chainsaws, Firewood, and Furry Friends

My old Labrador, Buster, used to love sprawling out in front of the wood stove. He’d be snoring away, completely oblivious to the work that went into keeping him warm. That work, of course, was all about firewood, and for years, my trusty Husqvarna 545 has been a key part of the process. Over time, I’ve learned a few tricks to boost its performance, especially when tackling tough hardwoods. This guide is all about those upgrades and pro tips, designed to help you cut firewood more efficiently and safely. Remember, a well-maintained and properly configured chainsaw is not only safer but also more enjoyable to use. And a warm house means happy pets!

Understanding the Task at Hand: Firewood Cutting Essentials

Before we get into the nitty-gritty of upgrades, let’s make sure we’re on the same page about the basics of firewood cutting.

• Green Wood vs. Seasoned Wood: Green wood is freshly cut wood with a high moisture content (often 50% or more). It’s harder to ignite, produces more smoke, and has lower heat output. Seasoned wood, on the other hand, has been air-dried for at least six months, reducing its moisture content to 20% or less. Seasoned wood burns hotter, cleaner, and is much easier to start. The difference is crucial for efficient heating and reducing creosote buildup in your chimney.
• Cord of Wood: A cord of wood is a precisely measured stack of wood equaling 128 cubic feet. This is typically arranged as a stack 4 feet high, 4 feet wide, and 8 feet long. Understanding this measurement is important for pricing and ordering firewood.
• Face Cord (or Rick): A face cord is a stack of wood 4 feet high and 8 feet long, but the width varies depending on the length of the firewood pieces. It’s a less precise measurement than a full cord, so always clarify the length of the wood when buying a face cord.

Husqvarna 545 Chainsaw CC Upgrades: 5 Pro Tips for Firewood Cutting

The Husqvarna 545 is a fantastic saw for firewood cutting. It’s powerful enough for most hardwoods, yet still relatively lightweight and easy to handle. However, like any tool, it can be improved upon. Here are my top 5 pro tips for upgrading your 545 for optimal firewood cutting:

1. Optimizing the Chain and Bar: Choosing the Right Cutting System

The chain and bar are the heart of any chainsaw’s cutting performance. Upgrading these can significantly improve your saw’s efficiency and cutting speed.

• Chain Selection: The stock chain on the 545 is usually a good all-around chain, but for dedicated firewood cutting, I recommend exploring specialized chains.
  • Full Chisel Chains: These chains have square-cornered teeth that offer the fastest cutting speed. They’re ideal for clean wood and experienced users. However, they dull more quickly in dirty or frozen wood. I’ve used Oregon 72LPX chains with great success in clean oak and maple.
  • Semi-Chisel Chains: These chains have rounded-cornered teeth that are more durable and forgiving in dirty or frozen wood. They’re a good choice for general firewood cutting, especially if you’re dealing with wood that’s been lying on the ground. Stihl RSC chains are a reliable option.
  • Low-Kickback Chains: These chains are designed to reduce the risk of kickback, a dangerous phenomenon where the saw suddenly jumps back towards the user. While they cut slower, they’re a good choice for beginners or those who prioritize safety.
  • Chain Pitch and Gauge: Make sure the chain you choose matches the pitch and gauge of your saw. The Husqvarna 545 typically uses a .325″ pitch and .058″ gauge chain. Using the wrong pitch or gauge can damage your saw and is unsafe.
• Bar Selection: The stock bar on the 545 is usually a 16″ or 18″ bar. While these are versatile, you might consider a different length depending on the size of the wood you’re cutting.
  • Bar Length: A shorter bar (e.g., 16″) is lighter and easier to maneuver, making it ideal for smaller logs and limbing. A longer bar (e.g., 20″) allows you to cut larger logs without having to roll them. However, a longer bar also requires more power and can be more tiring to use. For most firewood cutting with the 545, I find an 18″ bar to be a good compromise.
  • Bar Type: Solid bars are more durable and less prone to bending than laminated bars. However, they’re also heavier. Laminated bars are lighter and less expensive, making them a good choice for occasional use. I personally prefer solid bars for their durability, especially when cutting hardwoods.
  • Sprocket Nose vs. Hard Nose: Sprocket nose bars have a sprocket at the tip of the bar, which reduces friction and allows the chain to run more smoothly. Hard nose bars don’t have a sprocket and are more durable, but they also generate more friction. For firewood cutting, I recommend a sprocket nose bar.
• Chain Maintenance: No matter what chain you choose, it’s essential to keep it sharp and properly lubricated. A dull chain will not only cut slower but also put more strain on your saw and increase the risk of kickback.
  • Sharpening: Learn how to sharpen your chain using a file or a chain grinder. I prefer using a file for quick touch-ups in the field, and a chain grinder for more thorough sharpening. The correct file size for a .325″ pitch chain is typically 5/32″.
  • Lubrication: Use a high-quality bar and chain oil to keep your chain lubricated. Check the oil level frequently and refill as needed. I prefer using a vegetable-based bar and chain oil, as it’s more environmentally friendly and biodegradable.

Case Study: I once used a dull chain to cut through a large pile of oak logs. The saw struggled, the chain smoked, and it took me twice as long to finish the job. After switching to a freshly sharpened chain, the difference was night and day. The saw cut through the logs effortlessly, and I finished the job in half the time. This experience taught me the importance of keeping my chain sharp.

Data and Insights: A sharp chain can reduce cutting time by up to 50% and fuel consumption by up to 20%.

2. Carburetor Adjustment: Tuning for Optimal Performance

The carburetor is responsible for mixing air and fuel in the correct proportions. A properly adjusted carburetor will ensure that your saw runs smoothly, efficiently, and with maximum power.

• Understanding Carburetor Screws: Most carburetors have three adjustment screws:
  • L (Low-Speed) Screw: Adjusts the fuel mixture at idle and low speeds.
  • H (High-Speed) Screw: Adjusts the fuel mixture at high speeds.
  • LA (Idle Adjustment) Screw: Adjusts the idle speed.
• Carburetor Adjustment Procedure:
  1. Warm Up the Saw: Start the saw and let it warm up for a few minutes.
  2. Adjust the Idle Speed: Turn the LA screw until the chain stops moving at idle.
  3. Adjust the Low-Speed Screw: Turn the L screw until the engine runs smoothly at idle and responds quickly to throttle inputs. If the engine hesitates or stumbles when you accelerate, the L screw is likely too lean (not enough fuel). If the engine smokes or runs rough at idle, the L screw is likely too rich (too much fuel).
  4. Adjust the High-Speed Screw: This is the most critical adjustment and requires a tachometer to do it properly. The Husqvarna 545 has a maximum RPM of around 9,000 RPM. Use the tachometer to measure the engine speed at full throttle and adjust the H screw until you reach the maximum RPM. If the engine speed exceeds the maximum RPM, the H screw is likely too lean, which can damage the engine. If the engine speed is below the maximum RPM, the H screw is likely too rich, which will reduce power. Important: Adjusting the H screw too lean can cause serious engine damage. If you’re not comfortable doing this yourself, take your saw to a qualified technician.
• Specialized Carburetor Tools: Tamper-proof screws are common on modern chainsaws. You’ll need a specialized tool to adjust the carburetor screws. These tools are available online and at most chainsaw dealers.

Personalized Story: I once had a chainsaw that was running poorly. It was hard to start, idled rough, and lacked power. I took it to a local mechanic who adjusted the carburetor. The difference was amazing. The saw started easily, idled smoothly, and had plenty of power. This experience taught me the importance of carburetor adjustment.

Data and Insights: A properly adjusted carburetor can improve fuel efficiency by up to 10% and increase power by up to 15%.

3. Air Filter Upgrades: Breathing Easier for More Power

A clean air filter is essential for optimal engine performance. A dirty air filter restricts airflow, which reduces power and fuel efficiency.

• Air Filter Types:
  • Foam Filters: These filters are inexpensive and easy to clean. However, they don’t filter as well as other types of filters.
  • Felt Filters: These filters offer better filtration than foam filters but are more difficult to clean.
  • Nylon Mesh Filters: These filters are durable and easy to clean. They offer good filtration for general use.
  • HD Air Filters: Some aftermarket companies offer high-density air filters that provide superior filtration. These filters are ideal for dusty conditions.
• Air Filter Maintenance:
  • Cleaning: Clean your air filter regularly, especially when working in dusty conditions. Use compressed air to blow out the dirt and debris. You can also wash foam and nylon mesh filters with soap and water.
  • Replacement: Replace your air filter when it becomes damaged or excessively dirty. A clogged air filter starves the engine of air, causing it to run rich and lose power.
• Air Filter Modifications: Some users modify their air filters to improve airflow. This can be done by drilling holes in the filter housing or by removing the filter screen. However, these modifications can also allow more dirt and debris to enter the engine, which can cause damage. I don’t recommend these modifications unless you’re experienced and know what you’re doing.

Original Insights: In my experience, regularly cleaning the air filter is more important than upgrading to a fancy filter. A clean stock filter will perform better than a dirty high-performance filter.

Concrete Examples: I once spent an afternoon cutting firewood in a very dusty area. By the end of the day, my air filter was completely clogged. The saw was running poorly, and I had to stop frequently to clean the filter. This experience taught me the importance of checking and cleaning my air filter regularly, especially in dusty conditions.

Benefits and Strategic Advantages: A clean air filter ensures optimal airflow to the engine, resulting in increased power, improved fuel efficiency, and reduced engine wear.

4. Exhaust Modifications: Opening Up the Flow

Modifying the exhaust system can improve the engine’s breathing and increase power. However, these modifications can also increase noise levels and may void your warranty.

• Muffler Modification: The stock muffler on the Husqvarna 545 is designed to reduce noise levels. However, it can also restrict exhaust flow. Modifying the muffler can improve exhaust flow and increase power.
  • Drilling Holes: One common modification is to drill additional holes in the muffler. This increases exhaust flow but also increases noise levels.
  • Removing Baffles: Another modification is to remove the baffles inside the muffler. This further increases exhaust flow but also significantly increases noise levels.
• Aftermarket Mufflers: Some companies offer aftermarket mufflers that are designed to improve exhaust flow and increase power. These mufflers are typically louder than the stock muffler but may offer better performance.
• Considerations:
  • Noise Levels: Be aware that modifying the exhaust system will increase noise levels. This may be a concern if you live in a residential area or work near other people.
  • Warranty: Modifying the exhaust system may void your warranty.
  • Safety: Always wear ear protection when operating a chainsaw, especially with a modified exhaust system.

Measurements and Tool Specifications: When drilling holes in the muffler, start with small holes (e.g., 1/8″) and gradually increase the size until you achieve the desired performance. Use a drill bit designed for metal.

Case Study: I once modified the muffler on my Husqvarna 545 by drilling a few additional holes. The saw definitely had more power, but it was also noticeably louder. I eventually switched back to the stock muffler because I was concerned about the noise levels.

Strategic Insights: Exhaust modifications can improve power, but they also come with drawbacks. Consider the noise levels and warranty implications before making any modifications.

5. Ergonomics and Handling: Making Firewood Cutting Easier on Your Body

Firewood cutting can be physically demanding. Improving the ergonomics and handling of your chainsaw can reduce fatigue and improve safety.

• Handle Modifications:
  • Grips: Consider replacing the stock grips with aftermarket grips that are more comfortable and provide better grip.
  • Handle Wraps: Handle wraps can also improve grip and reduce vibration.
• Suspension Systems: Some aftermarket companies offer suspension systems that reduce vibration and improve comfort.
• Weight Reduction:
  • Lightweight Bar: Replacing the stock bar with a lightweight bar can reduce the overall weight of the saw.
  • Magnesium Components: Some aftermarket companies offer magnesium components that are lighter than the stock components.
• Proper Technique:
  • Stance: Maintain a stable stance with your feet shoulder-width apart.
  • Grip: Grip the saw firmly with both hands.
  • Body Position: Keep your body balanced and avoid reaching or overextending.
• Personalized Experience: One of the best investments I made was in a good pair of chainsaw chaps. They’ve saved me from potential injury more than once. Always prioritize safety gear!

Technical Details: Lightweight bars can reduce the weight of the saw by up to 1 pound.

Challenges Faced: Many DIYers struggle with fatigue when cutting firewood. Improving ergonomics and handling can significantly reduce fatigue and improve safety.

Practical Next Steps: Start by evaluating the ergonomics of your chainsaw. Are the grips comfortable? Is the saw well-balanced? Make small changes to improve comfort and handling.

Additional Pro Tips for Firewood Cutting

Beyond the 5 key upgrades, here are some additional tips I’ve learned over the years:

• Felling Techniques: Learn proper felling techniques to safely and efficiently fell trees. This includes understanding tree lean, wind direction, and escape routes. Always clear a path around the tree before felling it.
• Bucking Techniques: Bucking is the process of cutting a felled tree into manageable lengths. Use proper bucking techniques to avoid pinching the saw and to make splitting easier.
• Splitting Techniques: Splitting firewood can be done by hand with an axe or with a log splitter. A hydraulic log splitter is much faster and easier than splitting by hand, especially for large logs.
• Wood Stacking: Stack your firewood neatly and allow it to air dry for at least six months before burning it. Proper stacking allows for good airflow, which speeds up the drying process.
• Wood Selection: Choose the right type of wood for your needs. Hardwoods like oak and maple burn longer and produce more heat than softwoods like pine and fir.
• Safety Gear: Always wear appropriate safety gear when cutting firewood, including a helmet, eye protection, ear protection, chainsaw chaps, and gloves.
• Saw Maintenance: Regularly maintain your chainsaw by cleaning the air filter, sharpening the chain, and checking the spark plug.
• Fuel and Oil: Use the correct fuel and oil mixture for your chainsaw. Using the wrong mixture can damage the engine. Husqvarna 545 typically requires a 50:1 fuel to oil ratio.
• Storage: Store your chainsaw in a clean, dry place when not in use. Drain the fuel tank before storing the saw for extended periods.

Debarking Logs: While not always necessary for firewood, debarking logs before splitting can speed up the drying process and reduce insect infestation. A drawknife or debarking spud can be used for this purpose.

Drying Methods: Air drying is the most common method for seasoning firewood. However, you can also use a kiln to dry firewood more quickly. Kiln-dried firewood typically has a moisture content of 10-15%.

Firewood Stacking Case Study: I had a neighbor who always complained about his firewood not burning well. I noticed he was stacking it in a tight pile against his house, with no airflow. I suggested he restack it in a loose pile with space between the rows, and he was amazed at the difference in how well it burned the following year.

Costs and Material Specs: The cost of firewood can vary widely depending on the location and the type of wood. A cord of seasoned hardwood can cost anywhere from $200 to $400.

Timing Estimates: Air drying firewood typically takes 6-12 months, depending on the climate and the type of wood.

Skill Levels Required: Some firewood cutting tasks, such as felling trees, require advanced skills and experience. If you’re not comfortable with these tasks, hire a professional.

Global Considerations: The challenges faced by DIYers and small-scale logging businesses vary depending on the region. In some areas, access to equipment and resources may be limited. In other areas, regulations may be strict.

Implementation Guidance: Start with the basics: choose the right chain and bar, adjust the carburetor, and clean the air filter. Then, gradually implement the other tips as needed.

Benefits and Strategic Advantages: By following these tips, you can cut firewood more efficiently, safely, and enjoyably. You’ll also save money on fuel and reduce wear and tear on your chainsaw.
