Husqvarna 545 Chain Size Guide: 7 Expert Tips for Precision

Choosing the correct chain for your Husqvarna 545 chainsaw is crucial for optimal performance and safety. I’ve seen firsthand how the wrong chain can lead to inefficiencies, increased wear and tear on your saw, and even dangerous kickback situations. This guide will walk you through everything you need to know, from understanding chain specifications to selecting the best chain for your specific needs.

Understanding Chain Specifications

Before you can choose the right chain, you need to understand the terminology and specifications involved. This isn’t just about memorizing numbers; it’s about understanding how each aspect of the chain affects its performance.

• Pitch: The pitch is the distance between any three consecutive rivets divided by two. It’s usually expressed in inches (e.g., .325″, 3/8″). I’ve found that using the correct pitch is essential for smooth operation and prevents premature wear on the drive sprocket and bar.
• Gauge: The gauge is the thickness of the drive links, which fit into the groove of the guide bar. Common gauges include .050″, .058″, and .063″. Using the correct gauge ensures that the chain fits snugly in the bar groove, preventing excessive movement and potential derailment.
• Drive Link Count: This is the total number of drive links in the chain. The drive link count depends on the bar length. I always double-check the drive link count before purchasing a new chain to ensure a proper fit.
• Chain Type: Chains come in various types, including full chisel, semi-chisel, and low-kickback. Full chisel chains are sharpest and cut fastest but are more prone to kickback. Semi-chisel chains offer a good balance of cutting speed and safety. Low-kickback chains are designed for beginners and prioritize safety over speed.

Takeaway: Understanding these specifications is the first step towards selecting the right chain. Always refer to your Husqvarna 545’s manual for the recommended pitch, gauge, and drive link count.

Determining the Correct Chain Size for Your Husqvarna 545

The Husqvarna 545 is a versatile saw that can accommodate different bar lengths, each requiring a specific chain size. I’ve used this saw for everything from felling small trees to limbing larger ones, and the chain size always plays a critical role.

• Standard Bar Lengths: The Husqvarna 545 typically uses bar lengths ranging from 13 inches to 20 inches. The most common sizes are 16 and 18 inches.
• Pitch and Gauge Recommendation: The Husqvarna 545 usually uses a .325″ pitch and a .050″ or .058″ gauge chain. Always verify this information with your saw’s manual or the bar itself.
• Drive Link Count Chart:

Note: This chart is a general guideline. Always confirm the correct drive link count for your specific bar.

Takeaway: Use the chart as a starting point, but always double-check your bar length and the recommended drive link count before purchasing a new chain. I’ve learned this the hard way – a chain that’s even a few links off can be a real headache.

Choosing the Right Chain Type for Your Needs

The type of chain you choose depends on the type of wood you’re cutting and your level of experience. I’ve found that selecting the correct chain type significantly improves cutting efficiency and safety.

• Full Chisel Chains: These chains have square-cornered cutters that slice through wood quickly and efficiently. They are ideal for experienced users cutting clean, softwoods. However, they are more prone to kickback and require careful handling.
• Semi-Chisel Chains: These chains have rounded-corner cutters that are more forgiving and less prone to kickback. They are a good choice for general-purpose cutting and for users with less experience. I often recommend these to beginners.
• Low-Kickback Chains: These chains have special features that reduce the risk of kickback. They are designed for safety and are a good choice for beginners or for cutting in situations where kickback is a concern.
• Ripping Chains: These chains are designed for cutting wood along the grain, such as when milling lumber. They have a different cutter geometry than cross-cutting chains and provide a smoother, more efficient cut when ripping.

Takeaway: Consider the type of wood you’ll be cutting and your experience level when choosing a chain type. For general-purpose cutting, I usually recommend a semi-chisel chain.

Expert Tip #1: Measuring Your Existing Chain

If you’re unsure about the correct chain size for your Husqvarna 545, you can measure your existing chain to determine its specifications. I’ve used this method countless times, especially when dealing with older saws or bars where the markings have worn off.

• Measuring Pitch: Use a ruler or caliper to measure the distance between any three consecutive rivets. Divide this distance by two to determine the pitch.
• Measuring Gauge: Use a caliper to measure the thickness of the drive links.
• Counting Drive Links: Count the total number of drive links in the chain.

Takeaway: Measuring your existing chain is a reliable way to determine the correct specifications for a replacement. This is especially useful if you’re unsure about the original chain size.

Expert Tip #2: Checking Your Guide Bar

The guide bar plays a crucial role in chain performance. A worn or damaged bar can cause the chain to bind, cut unevenly, or even derail. I always inspect my guide bar before installing a new chain.

• Inspect for Wear: Check the bar rails for wear and tear. If the rails are uneven or have burrs, the bar needs to be dressed or replaced.
• Check the Groove: Make sure the bar groove is clean and free of debris. A clogged groove can prevent the chain from running smoothly.
• Lubrication: Ensure the bar is properly lubricated. Insufficient lubrication can cause excessive wear and tear on both the bar and the chain.

Takeaway: A well-maintained guide bar is essential for optimal chain performance and safety. Regularly inspect and maintain your bar to prolong its life and ensure smooth cutting.

Expert Tip #3: Sharpening Your Chain

A sharp chain is a safe chain. A dull chain requires more force to cut, increasing the risk of kickback and operator fatigue. I make it a habit to sharpen my chain regularly.

• Tools for Sharpening: You can sharpen your chain using a file, a grinder, or a specialized chainsaw sharpener. I prefer using a file for quick touch-ups in the field and a grinder for more thorough sharpenings.
• Sharpening Angle: Use the correct sharpening angle for your chain type. The recommended angle is usually printed on the chain packaging or in your saw’s manual.
• Maintaining Uniformity: Maintain a consistent angle and depth when sharpening each cutter. This will ensure that the chain cuts evenly and smoothly.

Takeaway: Regular chain sharpening is crucial for safety and efficiency. Learn how to sharpen your chain properly and make it a part of your routine maintenance.

Expert Tip #4: Chain Tensioning

Proper chain tension is essential for safe and efficient cutting. A chain that is too loose can derail, while a chain that is too tight can bind and cause excessive wear. I always check the chain tension before each use.

• Checking Tension: The chain should be snug against the bar but still able to be pulled around by hand. When you pull the chain away from the bar in the middle, you should be able to see approximately 1/8″ to 1/4″ of the drive links.
• Adjusting Tension: Use the chain tensioning screw to adjust the tension. Tighten the screw to increase tension and loosen it to decrease tension.
• Tensioning Hot Chains: When tensioning a hot chain, allow for some slack, as the chain will tighten as it cools.

Takeaway: Proper chain tension is crucial for safety and efficiency. Check and adjust the tension regularly, especially when using a new chain.

Expert Tip #5: Lubrication

Proper lubrication is essential for extending the life of your chain and bar. Insufficient lubrication can cause excessive wear and tear, leading to premature failure. I always use a high-quality bar and chain oil.

• Using the Right Oil: Use a bar and chain oil specifically designed for chainsaws. Avoid using motor oil or other lubricants, as they may not provide adequate lubrication.
• Checking the Oil Level: Check the oil level regularly and refill as needed. I usually check it every time I refuel the saw.
• Adjusting the Oil Flow: Some chainsaws allow you to adjust the oil flow. Increase the oil flow for harder woods or longer cuts.

Takeaway: Proper lubrication is crucial for extending the life of your chain and bar. Use a high-quality bar and chain oil and check the oil level regularly.

Case Study: Optimizing Chain Selection for a Logging Project

I once worked on a logging project where we were felling a large number of mature oak trees. Initially, we were using a standard semi-chisel chain, but we quickly realized that it wasn’t efficient enough for the dense hardwood.

• Problem: The semi-chisel chains were dulling quickly and requiring frequent sharpening. This slowed down our progress and increased our operating costs.
• Solution: We switched to a full chisel chain specifically designed for hardwood. This significantly improved our cutting speed and reduced the frequency of sharpening.
• Results: We were able to fell the trees much faster and more efficiently, saving time and money. The full chisel chain also provided a cleaner cut, which improved the quality of the lumber.

Takeaway: This case study highlights the importance of selecting the right chain type for the specific wood you’re cutting. Experiment with different chain types to find the best option for your needs.

Real-World Example: Firewood Preparation

When I prepare firewood, I often switch between different chains depending on the type of wood I’m cutting.

• Softwoods (Pine, Fir): For softwoods, I typically use a semi-chisel chain. These chains are sharp enough to cut through softwoods quickly and efficiently, and they are less prone to kickback than full chisel chains.
• Hardwoods (Oak, Maple): For hardwoods, I use a full chisel chain. These chains are designed for cutting dense wood and provide a cleaner, faster cut.
• Dirty Wood: If the wood is dirty or has been lying on the ground, I use an old chain that I don’t mind dulling. Cutting dirty wood can quickly dull a chain, so it’s best to use an expendable chain for this task.

Takeaway: Consider the type and condition of the wood you’re cutting when selecting a chain for firewood preparation. Having a variety of chains on hand can help you optimize your cutting efficiency.
