Echo 590 Chain Size Guide: 5 Tips for Optimal Woodcutting

I understand the frustration of dealing with a chainsaw that isn’t cutting properly. Whether it’s a chain that binds, a bar that overheats, or simply inefficient cutting, these problems can be avoided with the right knowledge. This guide will provide you with the knowledge you need.

Understanding Chain Size and Its Importance

Before diving into the specifics of the Echo 590, let’s cover the fundamentals of chainsaw chain size. This isn’t just about matching numbers; it’s about ensuring safety, efficiency, and prolonging the life of your chainsaw.

Key Components of a Chainsaw Chain

A chainsaw chain is more than just a loop of metal. It’s a complex piece of engineering comprised of several critical components:

• Cutters: These are the teeth that do the actual cutting. They come in various designs, such as chisel, semi-chisel, and chipper, each suited for different types of wood and cutting conditions.
• Drive Links: These links fit into the groove of the guide bar and are propelled by the chainsaw’s drive sprocket. The number of drive links determines the chain’s overall length.
• Tie Straps: These connect the cutters and drive links, providing structural integrity to the chain.
• Rivet Holes: These are the holes that connect each of the links in the chain together.
• Depth Gauges (Rakers): These control the amount of wood each cutter takes with each pass. Proper depth gauge filing is crucial for efficient cutting.

Chain Pitch, Gauge, and Drive Link Count

These three measurements are the cornerstones of chain size. Getting them right is non-negotiable.

• Pitch: This refers to the distance between three consecutive rivets on the chain, divided by two. Common pitches include 0.325″, 3/8″ (0.375″), and 0.404″. The Echo 590 typically uses a 0.325″ or 3/8″ pitch chain, depending on the specific bar installed.
• Gauge: This is the thickness of the drive links, measured where they fit into the guide bar groove. Common gauges include 0.050″, 0.058″, and 0.063″. The Echo 590 usually uses a 0.050″ or 0.058″ gauge chain.
• Drive Link Count: This is the total number of drive links in the chain. This number is crucial for ensuring the chain fits properly on your specific bar length.

Why are these measurements so important?

Mismatched chain size can lead to several problems:

• Chain Slippage: A chain that’s too loose can slip off the guide bar, posing a safety hazard.
• Chain Binding: A chain that’s too tight can bind in the cut, stalling the saw and potentially damaging the engine.
• Premature Wear: Using the wrong chain can accelerate wear on the chain, bar, and sprocket.
• Inefficient Cutting: An incorrectly sized or type of chain will not cut efficiently, wasting time and fuel.

Understanding Wood Types and Chain Selection

Different wood species have varying densities and hardness levels, which directly impact chain performance.

• Softwoods (Pine, Fir, Spruce): These are easier to cut and generally require less aggressive chain types. Chains with chisel cutters work well for softwoods.
• Hardwoods (Oak, Maple, Hickory): These are denser and require more aggressive chain types. Chains with semi-chisel or chisel cutters with hardened chrome plating are better suited for hardwoods.

My Experience:

I once tried using a standard chisel chain on a seasoned oak log. The chain dulled quickly, and the saw struggled to maintain its speed. Switching to a semi-chisel chain with a hardened surface made a world of difference, allowing for smoother and more efficient cutting.

Data on Wood Density

As you can see, Hickory is more than five times as dense as Balsa, highlighting the importance of choosing the right chain for the job. Using the wrong chain can significantly decrease your cutting efficiency and increase the risk of damage to your saw.

Tip 1: Determining the Correct Chain Size for Your Echo 590

Finding the right chain for your Echo 590 isn’t a guessing game. Here’s how to ensure you get the perfect fit.

Checking Your Chainsaw’s Manual

Your Echo 590’s owner’s manual is your best friend. It contains crucial information, including the recommended chain pitch, gauge, and drive link count for the specific bar length installed on your saw. Always refer to the manual first.

Why is this important?

Manufacturers specify chain sizes based on the saw’s engine power, bar length, and safety considerations. Deviating from these recommendations can compromise performance and safety.

Locating Information on the Guide Bar

The guide bar itself often contains stamped information about the recommended chain size. Look for markings that indicate the pitch and gauge. The drive link count may not be explicitly stated, but knowing the pitch and gauge allows you to determine the correct number of drive links.

Example:

A guide bar might be stamped with “3/8 .050”. This indicates a 3/8″ pitch and a 0.050″ gauge.

Counting Drive Links on Your Old Chain

If you’re replacing an existing chain, the easiest way to determine the correct drive link count is to count the drive links on the old chain. Lay the chain flat and carefully count each drive link.

Pro Tip:

Use a marker to make a starting point to avoid losing track.

Using an Online Chain Selector Tool

Many chainsaw chain manufacturers offer online chain selector tools. These tools allow you to input your chainsaw’s make and model, and they will provide you with a list of compatible chains.

Example:

Oregon Products offers a chain selector tool on their website. Simply enter “Echo 590,” and it will display the recommended chain options.

Consulting with a Chainsaw Professional

If you’re unsure about the correct chain size, don’t hesitate to consult with a chainsaw professional at your local hardware store or outdoor power equipment dealer. They can help you identify the right chain based on your saw and your cutting needs.

My Experience:

I once purchased a used Echo 590 that had a non-original guide bar installed. The markings on the bar were unclear, and I wasn’t sure which chain to use. I took the saw to a local dealer, and they quickly identified the correct chain size based on the bar and sprocket configuration.

Tip 2: Choosing the Right Chain Type for Your Needs

Not all chainsaw chains are created equal. Different chain types are designed for specific applications and wood types.

Chisel Chains

Chisel chains have square-cornered cutters that are very aggressive and efficient in clean wood. They are ideal for felling trees and cutting softwoods. However, they dull quickly if they come into contact with dirt or debris.

Pros:

• Fast cutting speed
• Efficient in clean wood

Cons:

• Dulls quickly
• Not suitable for dirty or abrasive conditions

Semi-Chisel Chains

Semi-chisel chains have rounded cutters that are more durable and forgiving than chisel chains. They are a good all-around choice for cutting a variety of wood types, including hardwoods and dirty wood.

Pros:

• More durable than chisel chains
• Suitable for a variety of wood types

Cons:

• Slower cutting speed than chisel chains

Chipper Chains

Chipper chains have rounded cutters that are very durable and resistant to dulling. They are ideal for cutting dirty wood, frozen wood, and hardwoods. However, they have the slowest cutting speed of the three chain types.

Pros:

• Very durable
• Resistant to dulling
• Suitable for dirty or frozen wood

Cons:

• Slowest cutting speed

Low-Kickback Chains

Low-kickback chains are designed with features that reduce the risk of kickback, a dangerous phenomenon that can occur when the tip of the guide bar contacts a solid object. These chains are a good choice for inexperienced chainsaw users or those who are working in tight spaces.

Features that reduce kickback:

• Bumper Drive Links: These links help prevent the chain from grabbing and kicking back.
• Depth Gauge Design: The depth gauges are designed to limit the amount of wood the cutters can take, reducing the force of kickback.

My Experience:

When I first started using a chainsaw, my grandfather insisted that I use a low-kickback chain. He emphasized that safety should always be the top priority, especially for beginners. While low-kickback chains may cut slightly slower, the added safety is well worth the trade-off.

Hardened Chains

Chains with hardened chrome plating or other specialized coatings are more resistant to wear and dulling, especially when cutting hardwoods or abrasive materials. These chains are a good investment for those who frequently cut tough wood.

Benefits of hardened chains:

• Longer lifespan
• Improved cutting performance in hardwoods
• Increased resistance to dulling

Tip 3: Maintaining Your Chainsaw Chain for Optimal Performance

A well-maintained chain is essential for safe and efficient woodcutting. Regular maintenance includes sharpening, tensioning, and lubrication.

A dull chain is not only inefficient but also dangerous. It requires more force to cut, increasing the risk of kickback and operator fatigue. Sharpen your chain regularly to maintain optimal cutting performance.

When to sharpen:

• When the chain is no longer cutting smoothly
• When the chain is producing sawdust instead of chips
• When the chain is pulling to one side

How to sharpen:

• Using a File and Guide: This is the most common method for sharpening chainsaw chains. A file and guide allow you to sharpen each cutter to the correct angle and depth.
• Using a Chainsaw Sharpener: These electric or manual sharpeners make it easier to sharpen chains quickly and accurately.

My Experience:

I learned to sharpen my chainsaw chain using a file and guide. It took some practice to get the hang of it, but it’s a valuable skill that has saved me a lot of time and money. My grandfather always said, “A sharp chain is a safe chain.”

Tensioning Your Chainsaw Chain

Proper chain tension is crucial for safe and efficient cutting. A chain that’s too loose can slip off the guide bar, while a chain that’s too tight can bind and overheat.

How to tension:

1. Loosen the bar nuts that secure the guide bar to the chainsaw.
2. Use the chain tensioning screw to adjust the chain tension.
3. The chain should be snug against the guide bar but still able to be pulled around by hand.
4. Tighten the bar nuts securely.

When to tension:

• Before each use
• After cutting for an extended period

Lubricating Your Chainsaw Chain

Chainsaw chains require constant lubrication to reduce friction and prevent overheating. Use a high-quality chainsaw bar and chain oil to keep your chain running smoothly.

How to lubricate:

• Fill the oil reservoir before each use.
• Check the oil level frequently during use.
• Adjust the oiler output if necessary.

My Experience:

I once neglected to check the oil level on my chainsaw, and the chain overheated and seized up. This caused significant damage to the chain and guide bar. I learned my lesson the hard way: always keep your chain properly lubricated.

Cleaning Your Chainsaw Chain

Regularly clean your chainsaw chain to remove sawdust, pitch, and other debris. This will help prevent wear and tear and maintain optimal cutting performance.

How to clean:

• Use a wire brush to remove debris from the chain.
