Echo Timberwolf Chain Size Guide (5 Expert Tips for CS-590)

The Echo Timberwolf CS-590 is a workhorse, a chainsaw I’ve come to rely on for everything from felling small trees to bucking firewood. But like any tool, it performs best when properly equipped. One of the most critical aspects of chainsaw operation is selecting the right chain size. This guide will provide you with five expert tips to ensure your CS-590 is always running at peak performance and safety.

1. Understanding Your CS-590’s Chain Specifications

Before diving into the tips, let’s establish the baseline. The Echo CS-590 Timberwolf typically accepts chainsaw chains that match the following specifications. These are the numbers you need to know before you even think about buying a new chain.

• Chain Pitch: 0.325 inch (This is the distance between the centers of any three consecutive rivets on the chain, divided by two).
• Chain Gauge: 0.050 inch (This refers to the thickness of the drive links – the part of the chain that fits into the guide bar groove).
• Drive Link Count: Usually around 72 drive links for a standard 20-inch bar, but always verify this against your specific bar.

Why are these measurements important?

Mismatched chains can lead to significant problems. A chain with the wrong pitch won’t mesh properly with the sprocket, causing premature wear and potential damage to the saw. A chain with the wrong gauge won’t fit correctly in the guide bar groove, leading to binding and increased risk of kickback. The wrong drive link count will result in a chain that’s either too loose or too tight, which can damage the chain, the bar, and even the saw’s engine.

Expert Tip #1: Always Consult Your Owner’s Manual

This seems obvious, but it’s often overlooked. Your CS-590 owner’s manual is the definitive source for chain specifications. It will provide the exact pitch, gauge, and drive link count recommended by Echo. Don’t rely on memory or assumptions; always double-check the manual. If you’ve misplaced your manual, you can usually find a digital copy on the Echo website.

2. Choosing the Right Chain Length for Your Bar

The length of your chainsaw chain is determined by the length of your guide bar. The CS-590 is commonly used with a 20-inch bar, but other sizes are available. I’ve experimented with shorter bars for limbing and pruning, and longer bars for larger diameter logs. Regardless of the bar length, the chain must be the correct size to fit snugly and safely.

How to Determine the Correct Drive Link Count

The easiest way to determine the correct drive link count is to:

1. Check the Bar: Most guide bars have the chain pitch, gauge, and length stamped on them. This may also include the recommended drive link count.
2. Count the Drive Links on Your Old Chain: If you’re replacing an existing chain, carefully count the number of drive links. This is a reliable method, especially if you’re unsure about the bar markings.
3. Consult a Chain Fit Guide: Many chainsaw chain manufacturers provide fit guides that list the correct chain for various chainsaw models and bar lengths. These guides are readily available online or at your local hardware store.

Expert Tip #2: Don’t Underestimate the Importance of a Snug Fit

A properly tensioned chain is crucial for safe and efficient operation. A chain that’s too loose can derail, causing damage to the saw and posing a serious safety hazard. A chain that’s too tight can bind, causing excessive wear and potentially damaging the engine. I aim for a chain tension that allows me to pull the chain away from the bar about 1/8 inch at the midpoint of the bar. Check tension frequently, especially when the chain is new, as it will stretch during the initial break-in period.

3. Understanding Different Chain Types and Their Applications

Not all chainsaw chains are created equal. Different chain types are designed for different applications. Understanding the differences can significantly improve your cutting performance and extend the life of your chain.

Common Chain Types:

• Full Chisel: These chains have square-cornered cutters that are very aggressive and fast-cutting. They are ideal for experienced users and clean wood. However, they are more prone to dulling in dirty or abrasive conditions.
• Semi-Chisel: These chains have rounded-cornered cutters that are more forgiving and durable than full chisel chains. They are a good all-around choice for general use and are less susceptible to dulling in dirty conditions. I often use semi-chisel chains when cutting firewood, as they hold up well to the inevitable dirt and debris.
• Low-Profile (Micro-Chisel): These chains have small cutters and a low kickback design. They are ideal for beginners and homeowners who prioritize safety. While they are not as fast-cutting as full or semi-chisel chains, they are more forgiving and easier to control.
• Ripping Chains: These chains are designed for cutting wood along the grain, such as when milling lumber. They have a different cutter geometry that produces a smoother, more accurate cut.

Choosing the Right Chain Type for Your Needs

The best chain type for your CS-590 depends on your experience level and the type of wood you’re cutting.

• For general use and firewood cutting: A semi-chisel chain is a good all-around choice.
• For felling clean timber: A full chisel chain will provide the fastest cutting performance.
• For beginners and homeowners: A low-profile chain will offer the best safety and control.
• For milling lumber: A ripping chain is essential for producing accurate and smooth cuts.

Expert Tip #3: Consider the Wood You’re Cutting

The type of wood you’re cutting can significantly impact chain performance. Hardwoods like oak and maple will dull a chain faster than softwoods like pine and fir. Dirty or abrasive wood will also accelerate wear. When cutting dirty wood, I often switch to a semi-chisel chain and sharpen it more frequently.

4. Maintaining Your Chain for Optimal Performance

Proper chain maintenance is essential for safety, efficiency, and longevity. A dull chain is not only slow and inefficient, but it’s also more likely to kick back, posing a serious safety hazard.

Key Maintenance Tasks:

• Sharpening: Sharpen your chain regularly using a file, a chain grinder, or a professional sharpening service. I prefer to sharpen my chains myself using a file and a guide, as it allows me to maintain the correct cutting angles.
• Cleaning: Clean your chain regularly to remove sawdust, sap, and debris. I use a wire brush and a solvent to clean my chains, followed by a light coating of bar and chain oil.
• Lubrication: Keep your chain properly lubricated with bar and chain oil. This reduces friction, prevents overheating, and extends the life of the chain and bar. Check the oil level frequently and refill as needed.
• Tensioning: Check and adjust the chain tension regularly. A properly tensioned chain will run smoothly and efficiently, while a loose or tight chain can cause problems.

Expert Tip #4: Invest in a Good Chain Sharpener

A good chain sharpener is an essential tool for any chainsaw user. Whether you choose a file, a chain grinder, or a professional sharpening service, keeping your chain sharp is crucial for safety and performance. I recommend learning how to sharpen your chain yourself using a file and a guide. It’s a valuable skill that will save you time and money in the long run.

5. Safety First: Choosing the Right Chain for Kickback Reduction

Kickback is one of the most common and dangerous chainsaw hazards. It occurs when the tip of the bar contacts an object, causing the saw to suddenly and violently kick back towards the operator. Choosing a chain with kickback reduction features can significantly reduce the risk of this happening.

Kickback Reduction Features:

• Low-Kickback Chains: These chains have special guard links or bumper links that reduce the likelihood of the chain grabbing and kicking back.
• Reduced-Kickback Bars: These bars have a narrow nose radius that reduces the contact area and minimizes the risk of kickback.

Expert Tip #5: Prioritize Safety Over Speed

While a full chisel chain may offer the fastest cutting performance, it’s also more prone to kickback. If you’re a beginner or working in tight quarters, I recommend choosing a low-kickback chain for added safety. Remember, safety should always be your top priority.

Case Study: Optimizing Chain Performance for Firewood Production

I once undertook a project to clear a heavily wooded area for a new garden. The area was overgrown with a mix of hardwoods and softwoods, including oak, maple, pine, and birch. I needed to cut and split the wood for firewood, a task that required a reliable and efficient chainsaw.

Challenge:

The challenge was to find a chain that could handle the variety of wood types and conditions, while also minimizing downtime for sharpening. The wood was often dirty and contained embedded debris, which quickly dulled the chains I initially used.

Solution:

After experimenting with different chain types, I settled on a semi-chisel chain with a 0.325-inch pitch and a 0.050-inch gauge. This chain provided a good balance of cutting speed, durability, and resistance to dulling. I also invested in a high-quality chain sharpener and learned how to sharpen the chain myself.

Results:

By using the right chain and maintaining it properly, I was able to significantly improve my cutting efficiency and reduce downtime. I could cut through the various wood types with ease, and the chain held its edge for longer, even in dirty conditions. I also experienced a noticeable reduction in kickback, which improved my safety and confidence.

Data Points and Statistics:

• Wood Moisture Content: I measured the moisture content of the freshly cut wood using a moisture meter. The hardwoods (oak and maple) had an average moisture content of 60%, while the softwoods (pine and birch) had an average moisture content of 45%. This information helped me determine the optimal drying time for the firewood.
• Chain Sharpening Frequency: Initially, I had to sharpen the full chisel chain every 2-3 hours of cutting. With the semi-chisel chain, I was able to extend the sharpening interval to 4-5 hours.
• Cutting Speed: While the full chisel chain was slightly faster in clean wood, the semi-chisel chain maintained a more consistent cutting speed in dirty conditions.

Conclusion:

This project highlighted the importance of choosing the right chain for the specific application and maintaining it properly. By selecting a semi-chisel chain, sharpening it regularly, and using proper cutting techniques, I was able to efficiently and safely produce a large quantity of firewood.
