• Torque, Max: 2.6 Nm at 6600 rpm – Torque is the twisting force the engine applies to the chain. Higher torque means the chainsaw can maintain its cutting speed even when encountering resistance.
• Fuel Tank Volume: 0.52 l (17.6 fl oz) – A decent-sized fuel tank allows for extended cutting sessions without frequent refueling.
• Oil Tank Volume: 0.27 l (9.1 fl oz) – Proper chain lubrication is crucial for smooth cutting and extending the life of the chain and bar.
• Recommended Bar Length: 13″-20″ – Choosing the right bar length depends on the size of the wood you’re cutting. A longer bar is useful for felling large trees, while a shorter bar is more maneuverable for limbing and bucking. I generally find a 16″ bar to be the sweet spot for all-around use.
• Chain Pitch: .325″ – The chain pitch is the distance between the drive links on the chain. A .325″ pitch chain is a good compromise between cutting speed and durability.
• Chain Gauge: .050″ – The chain gauge is the thickness of the drive links. A .050″ gauge chain is a common and reliable choice.
• Weight (excl. cutting equipment): 4.9 kg (10.8 lbs) – Weight is a critical factor, especially when working for extended periods. The 545 is relatively lightweight for its power, reducing fatigue.
• Sound Pressure Level at Operator’s Ear: 106 dB(A) – Chainsaws are noisy machines. Always wear hearing protection!
• Sound Power Level, Guaranteed (LWA): 116 dB(A) – This is the overall noise level emitted by the chainsaw.
• Vibration Level (ahv, eq) Front Handle: 3.1 m/s² – Vibration can lead to fatigue and long-term health problems. The 545 features anti-vibration technology to minimize these effects.
• Vibration Level (ahv, eq) Rear Handle: 4.9 m/s² – The rear handle typically experiences higher vibration levels due to its proximity to the engine.

The Heart of the Matter: Engine Technology and Performance

The Husqvarna 545 isn’t just about raw power; it’s about smart power. Husqvarna’s X-Torq engine technology plays a significant role in its performance. X-Torq engines are designed to:

• Reduce Fuel Consumption: By optimizing combustion, X-Torq engines can reduce fuel consumption by up to 20% compared to traditional two-stroke engines. This saves you money and reduces your environmental impact.

The Husqvarna 545 is a versatile chainsaw, but its performance can vary depending on the type of wood you’re cutting. Understanding the properties of different wood species is crucial for selecting the right cutting techniques and chain types.

• Softwoods: Pine, fir, spruce, cedar – Softwoods are generally easier to cut than hardwoods due to their lower density. The 545 can handle softwoods with ease, making it ideal for tasks like felling and limbing.
• Hardwoods: Oak, maple, birch, ash – Hardwoods are denser and more resistant to cutting. While the 545 can handle hardwoods, it may require more effort and a sharper chain.
• Exotic Hardwoods: Ipe, teak, mahogany – These woods are extremely dense and can be challenging to cut with any chainsaw. The 545 may struggle with very hard exotic woods, and specialized chains and techniques may be required.

Here’s a table showing the density of various wood species (in kg/m³):

As you can see, the density of wood can vary significantly. When cutting denser woods, it’s important to:

• Use a sharp chain: A dull chain will struggle to cut through hardwoods, leading to increased effort and potential kickback.
• Maintain a steady cutting speed: Don’t force the chainsaw. Let the chain do the work.
• Lubricate the chain frequently: Hardwoods can generate more friction, so proper lubrication is essential.

Pro Tip #1: Mastering Chain Selection and Maintenance

The chain is arguably the most important part of your chainsaw. A well-maintained, properly selected chain can make all the difference in cutting performance and safety.

• Chain Types: There are various types of chainsaw chains, each designed for specific applications.
  • Full Chisel: These chains have square-cornered cutters that provide the fastest cutting speed but are more prone to dulling in dirty conditions.
  • Semi-Chisel: These chains have rounded-corner cutters that are more durable and less prone to dulling than full chisel chains. They’re a good all-around choice for general wood processing.
  • Low-Profile: These chains have smaller cutters and are designed for safety. They’re less aggressive than full or semi-chisel chains but are less likely to kick back.
• Sharpening: A dull chain is not only inefficient but also dangerous. Learn how to sharpen your chain properly using a file and guide. I recommend sharpening your chain every time you refuel.
• Tensioning: Proper chain tension is crucial for safe and efficient cutting. A chain that’s too loose can derail, while a chain that’s too tight can overheat and break. Check the chain tension regularly and adjust as needed.
• Lubrication: Use a high-quality bar and chain oil to keep the chain properly lubricated. Proper lubrication reduces friction, extends the life of the chain and bar, and prevents overheating. I prefer using a bio-degradable chain oil to minimize my environmental impact.

I’ve seen countless accidents caused by dull or improperly maintained chains. Take the time to learn how to sharpen and maintain your chain, and you’ll be rewarded with better performance and increased safety.

Pro Tip #2: Optimizing Cutting Techniques for Efficiency

Knowing how to cut wood efficiently can save you time, energy, and wear and tear on your chainsaw. Here are some techniques I’ve found particularly useful:

• Felling: Felling is the process of cutting down a tree. It’s a complex and potentially dangerous task that requires careful planning and execution.
  • Assess the tree: Before felling a tree, assess its size, lean, and any potential hazards, such as dead branches or power lines.
  • Plan your escape route: Always have a clear escape route planned in case the tree falls in an unexpected direction.
  • Make the notch: The notch is a wedge-shaped cut that determines the direction of the fall. It should be about 1/3 of the tree’s diameter.
  • Make the back cut: The back cut is made on the opposite side of the tree from the notch. Leave a hinge of wood between the back cut and the notch to control the fall.
  • Use wedges: If the tree is leaning in the wrong direction, use felling wedges to help guide its fall.
• Limbing: Limbing is the process of removing branches from a felled tree.
  • Work from the base to the top: Start by removing the branches closest to the base of the tree and work your way towards the top.
  • Use a sweeping motion: Use a sweeping motion to cut the branches, keeping the chainsaw moving smoothly.
  • Be aware of kickback: Limbing can be particularly prone to kickback, so be extra careful.
• Bucking: Bucking is the process of cutting a felled tree into smaller, more manageable lengths.
  • Support the log: Make sure the log is properly supported to prevent it from pinching the chain.
  • Use the right cutting technique: Depending on the size and position of the log, you may need to use different cutting techniques, such as overbucking, underbucking, or bore cutting.
  • Be aware of tension: Logs can be under tension, which can cause them to split or move unexpectedly when cut. Be prepared for this and take appropriate precautions.

I once saw a logger get seriously injured because he didn’t properly assess the lean of a tree before felling it. The tree fell in the wrong direction and pinned him against another tree. Fortunately, he survived, but it was a close call. Always take the time to plan your cuts carefully and be aware of your surroundings.

Pro Tip #3: Mastering the Bore Cut

The bore cut is an advanced technique that allows you to cut through a log without cutting all the way through from the top or bottom. It’s particularly useful for relieving tension in logs and preventing pinching.

Here’s how to perform a bore cut:

1. Position yourself safely: Stand to the side of the log, with your feet firmly planted.
2. Start the chainsaw: Make sure the chain is properly lubricated and the engine is running smoothly.
3. Plunge the bar into the log: With the tip of the bar, carefully plunge into the log at a slight angle. Use the lower part of the bar to initiate the cut and avoid kickback.
4. Pivot the bar: Once the bar is fully inserted into the log, pivot it to create a horizontal cut.
5. Complete the cut: Continue pivoting the bar until you’ve cut through the desired section of the log.
6. Remove the bar: Carefully remove the bar from the log, avoiding any sudden movements.

The bore cut takes practice, but it’s a valuable skill to have in your arsenal. It can help you avoid pinching, control the direction of the cut, and prevent the log from splitting.

Pro Tip #4: Fine-Tuning the Husqvarna 545 for Milling

While the Husqvarna 545 isn’t a dedicated milling chainsaw, it can be used for small-scale milling projects with some modifications and careful technique.

• Choose the Right Bar and Chain: Opt for a longer bar (18-20″) with a ripping chain specifically designed for milling. Ripping chains have a different grind angle that allows them to cut parallel to the wood grain more efficiently.
• Use a Chainsaw Mill Attachment: A chainsaw mill attachment provides a stable platform for guiding the chainsaw along the log, ensuring accurate and consistent cuts.
• Adjust Carburetor Settings (If Necessary): Milling requires the chainsaw to run at a sustained high RPM. You may need to adjust the carburetor settings to ensure the engine is getting enough fuel and air. Consult your owner’s manual for instructions.
• Take Your Time: Milling is a slow and deliberate process. Don’t rush it. Take your time to ensure accurate cuts and avoid overheating the chainsaw.
• Keep the Chain Sharp: A sharp chain is essential for efficient milling. Sharpen the chain frequently, as milling can quickly dull the cutters.
• Consider an Auxiliary Oiler: Milling puts extra strain on the bar and chain lubrication system. An auxiliary oiler can help ensure adequate lubrication and prevent premature wear.

Milling with the Husqvarna 545 is best suited for smaller logs and occasional projects. For larger-scale milling, a more powerful chainsaw specifically designed for milling is recommended.

Pro Tip #5: Prioritizing Safety Above All Else

Chainsaws are powerful tools that can cause serious injury if not used properly. Safety should always be your top priority.

• Wear Proper Safety Gear: Always wear a helmet with a face shield, hearing protection, gloves, chaps, and sturdy boots when operating a chainsaw.
• Read the Owner’s Manual: Familiarize yourself with the chainsaw’s operating instructions and safety precautions.
• Maintain a Safe Working Distance: Keep bystanders at least two tree lengths away from the cutting area.
• Be Aware of Kickback: Kickback is a sudden and violent reaction that can occur when the chain catches on an object. Be aware of the potential for kickback and take steps to avoid it.
• Never Cut Above Shoulder Height: Cutting above shoulder height is dangerous and can lead to loss of control.
• Never Operate a Chainsaw When Fatigued or Under the Influence: Chainsaws require focus and concentration. Never operate a chainsaw when you’re tired, distracted, or under the influence of drugs or alcohol.
• Inspect Your Chainsaw Regularly: Before each use, inspect your chainsaw for any signs of damage or wear. Make sure the chain is sharp, the bar is properly lubricated, and all safety features are functioning correctly.
• Take a Chainsaw Safety Course: Consider taking a chainsaw safety course to learn proper operating techniques and safety procedures.

I’ve seen too many accidents caused by complacency and disregard for safety. Always take the time to assess the risks and take appropriate precautions. Your safety is worth more than any amount of wood.
