Husqvarna Chainsaw Chain Size Chart (5 Pro Filing Tips)

Have you ever watched your furry friend tilt their head inquisitively as you fire up your chainsaw? My golden retriever, Gus, certainly does. While he’s fascinated by the noise and the flying wood chips, it’s a good reminder that safety and precision are paramount when working with power tools. One of the most crucial aspects of chainsaw safety and performance is understanding your chain size and how to keep it properly filed.

Why Understanding Your Husqvarna Chainsaw Chain Matters

Think of your chainsaw chain as the teeth of a very hungry beast. A dull or improperly sized chain not only makes your work harder and slower, but it also increases the risk of kickback and other dangerous situations. A sharp, well-maintained chain, on the other hand, allows you to work efficiently, safely, and with greater control.

Imagine trying to chop wood with a butter knife. Frustrating, right? A dull chainsaw chain is no different. It forces you to apply more pressure, which can lead to fatigue and increase the likelihood of accidents. Moreover, a dull chain produces fine sawdust instead of larger chips, indicating that it’s rubbing instead of cutting. This creates more friction and heat, potentially damaging your chainsaw’s bar and engine.

The stakes are high:

• Safety: A sharp chain reduces the risk of kickback and other accidents.
• Efficiency: A sharp chain cuts faster and requires less effort.
• Longevity: Proper chain maintenance extends the life of your chainsaw.
• Quality: A sharp chain produces cleaner cuts, which is crucial for woodworking projects.

Understanding Husqvarna Chainsaw Chain Sizes

Husqvarna chainsaws are renowned for their quality and performance, but they come in a variety of sizes and configurations. To choose the right chain for your chainsaw, you need to understand the key specifications: pitch, gauge, and drive link count.

Pitch: The Chain’s DNA

The pitch is the distance between any three consecutive rivets on the chain, divided by two. It’s usually expressed in inches. Common chainsaw pitches include .325″, 3/8″, and .404″. The pitch determines the size of the teeth and the overall aggressiveness of the chain.

• .325″ Pitch: This is a popular choice for mid-sized chainsaws used for general-purpose cutting, such as felling small trees, limbing, and cutting firewood.
• 3/8″ Pitch: This is a versatile pitch suitable for a wide range of chainsaws, from mid-sized to larger models. It’s a good choice for felling larger trees and heavy-duty cutting tasks.
• .404″ Pitch: This is typically used on larger, professional-grade chainsaws designed for felling large trees and heavy-duty logging operations.

Here’s a simple way to measure pitch:

1. Measure the distance between any three consecutive rivets on the chain.
2. Divide that measurement by two.
3. The result is your chain’s pitch.

Gauge: The Chain’s Thickness

The gauge is the thickness of the drive links, which are the parts of the chain that fit into the groove of the chainsaw bar. It’s usually expressed in thousandths of an inch. Common chainsaw gauges include .043″, .050″, .058″, and .063″. The gauge must match the width of the groove on your chainsaw bar.

• .043″ Gauge: This is a relatively narrow gauge often found on smaller chainsaws.
• .050″ Gauge: This is a common gauge for mid-sized chainsaws.
• .058″ Gauge: This is a slightly wider gauge often found on larger chainsaws.
• .063″ Gauge: This is the widest common gauge, typically used on heavy-duty chainsaws.

Pro Tip: The gauge is usually stamped on the chainsaw bar near the mounting point. If you can’t find it, consult your chainsaw’s manual.

Drive Link Count: The Chain’s Length

The drive link count is the number of drive links in the chain. This determines the overall length of the chain and must match the length of your chainsaw bar. The drive link count is usually stamped on the chainsaw bar or listed in the chainsaw’s manual.

Why is drive link count so important?

• Proper Fit: The chain must fit snugly on the bar without being too tight or too loose.
• Safety: An improperly sized chain can derail or break, posing a safety hazard.
• Performance: An improperly sized chain can cause excessive wear on the bar and chain.

Finding the Right Chain for Your Husqvarna Chainsaw

The best way to find the right chain for your Husqvarna chainsaw is to consult your chainsaw’s manual or the Husqvarna website. You can also use Husqvarna’s chain selector tool, which allows you to enter your chainsaw model and find the correct chain size.

Example: Let’s say you have a Husqvarna 455 Rancher chainsaw. According to Husqvarna’s website, the recommended chain size is 3/8″ pitch, .050″ gauge, and 72 drive links for a 20″ bar.

The Importance of a Husqvarna Chainsaw Chain Size Chart

A chainsaw chain size chart is an invaluable resource for anyone who owns or operates a chainsaw. It provides a quick and easy way to determine the correct chain size for your specific chainsaw model. Think of it as a cheat sheet for chainsaw chain compatibility.

The Art of Chainsaw Chain Filing: 5 Pro Tips

Now that you understand the importance of chain size, let’s move on to the art of chainsaw chain filing. A sharp chain is a safe chain, and proper filing is the key to maintaining a sharp chain. These are the 5 pro filing tips I use on a regular basis.

Tip 1: Gather Your Tools

Before you start filing, make sure you have the right tools. You’ll need:

• A Chainsaw Vise: This holds the chainsaw bar securely while you file.
• Round Files: These are used to sharpen the cutting teeth. You’ll need the correct size file for your chain’s pitch.
• A Flat File: This is used to lower the depth gauges.
• A Depth Gauge Tool: This helps you maintain the correct depth gauge settings.
• A File Guide: This helps you maintain the correct filing angle.
• Gloves: Protect your hands from sharp teeth.
• Safety Glasses: Protect your eyes from metal filings.

Choosing the Right Round File

The size of the round file is crucial for achieving the correct cutting angle and sharpness. Here’s a general guide:

• .325″ Pitch Chains: Use a 5/32″ (4.0 mm) or 13/64″ (5.2 mm) round file.
• 3/8″ Pitch Chains: Use a 5/32″ (4.8 mm) or 3/16″ (5.5 mm) round file.
• .404″ Pitch Chains: Use a 7/32″ (5.5 mm) round file.

My Personal Experience: I once tried to sharpen a 3/8″ pitch chain with a 5/32″ file because it was the only one I had on hand. The result was a chain that was sharp but cut very aggressively and was prone to kickback. Lesson learned: always use the correct size file.

Tip 2: Secure the Chainsaw

Place the chainsaw in the vise and tighten it securely. Make sure the bar is stable and doesn’t move while you’re filing. This is crucial for achieving consistent results.

Why is a vise so important?

• Stability: Prevents the chainsaw from moving while you file.
• Safety: Reduces the risk of injury.
• Consistency: Allows you to maintain consistent filing angles.

Alternative to a Vise: If you don’t have a vise, you can use a stump or a log to secure the chainsaw bar. Just make sure it’s stable and won’t move while you’re filing.

Tip 3: File the Cutting Teeth

Start by identifying the shortest cutting tooth. This will be your guide for filing the other teeth. Hold the round file at the correct angle (usually marked on the file guide) and file each tooth using smooth, even strokes. File from the inside of the tooth to the outside, following the curve of the tooth.

Maintaining the Correct Filing Angle

The filing angle is critical for achieving optimal cutting performance. Most file guides have markings to help you maintain the correct angle. Here’s a general guide:

• Top Angle: The angle of the file relative to the top of the tooth. This is usually around 25-35 degrees.
• Side Angle: The angle of the file relative to the side of the tooth. This is usually around 60-70 degrees.

Filing Technique

• Consistent Strokes: Use smooth, even strokes to file each tooth.
• Light Pressure: Apply light pressure to avoid overheating the tooth.
• Count Strokes: Count the number of strokes you use on each tooth to ensure consistency.
• File All Teeth: File all the teeth on one side of the chain, then flip the chainsaw and file the teeth on the other side.

Common Mistakes to Avoid

• Filing Too Deep: Filing too deep can weaken the tooth and make it prone to breaking.
• Filing at the Wrong Angle: Filing at the wrong angle can result in a chain that cuts poorly or is prone to kickback.
• Using a Dull File: A dull file will not sharpen the teeth effectively and can damage the chain.

Tip 4: Lower the Depth Gauges

The depth gauges are the small, rounded teeth located in front of the cutting teeth. They control how much wood the cutting teeth can bite into. As you sharpen the cutting teeth, the depth gauges become relatively higher. If they’re too high, the chain won’t cut effectively.

Using a Depth Gauge Tool

1. Place the depth gauge tool over the depth gauge.
2. File the depth gauge until it’s flush with the top of the tool.
3. Round off the front of the depth gauge with the flat file.

Why are Depth Gauges Important?

• Cutting Performance: Depth gauges control how much wood the cutting teeth can bite into.
• Kickback Prevention: Properly adjusted depth gauges help prevent kickback.
• Safety: Ensures the chain cuts smoothly and safely.

My Personal Experience: I once neglected to lower the depth gauges after sharpening my chain. The result was a chain that wouldn’t cut effectively, even though the cutting teeth were razor sharp. It was like trying to cut wood with a saw that had no set.

Tip 5: Inspect and Lubricate

After filing, inspect the chain for any damage or wear. Check the rivets, tie straps, and drive links for cracks or excessive wear. Lubricate the chain with chainsaw bar and chain oil before using it.

Why is Lubrication Important?

• Reduces Friction: Lubrication reduces friction between the chain and the bar.
• Extends Chain Life: Proper lubrication extends the life of the chain.
• Prevents Overheating: Lubrication helps prevent the chain from overheating.
• Improves Cutting Performance: A well-lubricated chain cuts more smoothly and efficiently.

Choosing the Right Bar and Chain Oil

• Viscosity: Choose an oil with the correct viscosity for your chainsaw and the ambient temperature.
• Tackiness: Choose an oil with good tackiness to prevent it from being thrown off the chain.
• Biodegradability: Consider using a biodegradable oil to reduce your environmental impact.

My Personal Preference: I prefer to use a synthetic bar and chain oil because it provides excellent lubrication and protection, even in extreme temperatures.

Wood Anatomy and Properties: Understanding Your Material

To truly master chainsaw operation, it’s helpful to understand the wood you’re cutting. Different types of wood have different properties that affect how they cut and how they’re best processed.

Hardwood vs. Softwood

The terms “hardwood” and “softwood” refer to the type of tree, not necessarily the actual hardness of the wood. Hardwoods come from deciduous trees (trees that lose their leaves in the fall), while softwoods come from coniferous trees (trees that have needles and cones).

Hardwood Characteristics:

• Higher Density: Hardwoods are generally denser than softwoods.
• Slower Growth: Hardwoods typically grow slower than softwoods.
• More Complex Grain: Hardwoods often have more complex and intricate grain patterns.
• Greater Durability: Hardwoods are generally more durable and resistant to decay than softwoods.

Softwood Characteristics:

• Lower Density: Softwoods are generally less dense than hardwoods.
• Faster Growth: Softwoods typically grow faster than hardwoods.
• Simpler Grain: Softwoods often have simpler and more uniform grain patterns.
• Lower Durability: Softwoods are generally less durable and resistant to decay than hardwoods.

Examples of Hardwoods: Oak, maple, cherry, walnut, ash, birch.

Examples of Softwoods: Pine, fir, spruce, cedar, redwood.

How Wood Type Affects Cutting

• Hardwoods: Hardwoods require more power to cut and can dull your chain faster. Use a sharp chain and a steady hand.
• Softwoods: Softwoods are easier to cut but can be more prone to splintering. Use a sharp chain and avoid forcing the saw.

My Personal Experience: I once tried to fell a large oak tree with a dull chain. It was a grueling experience that took much longer than it should have. The chain kept binding, and the saw was constantly overheating. I learned the hard way that a sharp chain is essential for cutting hardwoods.

Wood Moisture Content

The moisture content of wood is the amount of water it contains, expressed as a percentage of its oven-dry weight. Moisture content affects the weight, strength, and stability of wood.

Freshly Cut Wood (Green Wood):

• High Moisture Content: Can range from 30% to over 200%, depending on the species.
• Heavy: Green wood is much heavier than dry wood.
• Difficult to Cut: Green wood can be more difficult to cut because the moisture can bind the chain.
• Prone to Warping and Cracking: Green wood is prone to warping and cracking as it dries.

Seasoned Wood (Dry Wood):

• Low Moisture Content: Typically below 20%.
• Light: Seasoned wood is much lighter than green wood.
• Easier to Cut: Seasoned wood is easier to cut because the moisture has evaporated.
• More Stable: Seasoned wood is more stable and less prone to warping and cracking.

How Moisture Content Affects Cutting

• Green Wood: Use a sharp chain and avoid forcing the saw. Consider using a bar and chain oil designed for green wood.
• Seasoned Wood: Use a sharp chain and a bar and chain oil designed for dry wood.

My Personal Tip: When cutting green wood, I often stop and clean the chain more frequently to remove sap and debris that can build up and reduce cutting performance.

Logging Tool Selection and Maintenance Best Practices

Beyond the chainsaw, several other logging tools can make your work easier, safer, and more efficient. Here are some essential tools and best practices for their maintenance.

• Kiln Drying: A faster method of seasoning firewood. The wood is placed in a kiln and dried using heat.
• Solar Drying: A method of seasoning firewood that uses solar energy to dry the wood.

Air Drying: The Gold Standard

Air drying is a simple yet effective method. Here’s how I do it:

1. Split the Wood: Split the wood into manageable sizes to speed up the drying process.
2. Stack the Wood: Stack the wood in a single row, with space between the pieces for air circulation.
3. Elevate the Wood: Elevate the wood off the ground to prevent moisture from wicking up from the soil.
4. Cover the Top: Cover the top of the woodpile with a tarp or sheet of metal to protect it from rain and snow.
5. Choose a Sunny Location: Choose a sunny, well-ventilated location for the woodpile.

Factors Affecting Seasoning Time:

• Wood Species: Hardwoods take longer to season than softwoods.
• Climate: Warmer, drier climates allow wood to season faster.
• Stacking Method: Proper stacking and air circulation speed up the seasoning process.

How to Tell if Firewood is Seasoned

• Weight: Seasoned firewood is much lighter than green firewood.
• Color: Seasoned firewood is often darker in color than green firewood.
• Cracks: Seasoned firewood often has cracks in the end grain.
• Sound: Seasoned firewood makes a hollow sound when struck together.

Data Point: According to the U.S. Department of Energy, burning seasoned firewood can increase heating efficiency by as much as 25%.

Firewood Safety Considerations

• Stacking Stability: Stack firewood in a stable manner to prevent it from collapsing.
• Pest Control: Keep firewood away from your house to prevent pests from entering your home.
• Carbon Monoxide: Never burn firewood in an unventilated space, as this can lead to carbon monoxide poisoning.
• Chimney Maintenance: Have your chimney inspected and cleaned regularly to prevent chimney fires.

Personal Anecdote: I once had a close call with carbon monoxide poisoning. I was burning firewood in my wood stove on a cold winter night. I closed the damper too much, which caused carbon monoxide to build up in the house. Luckily, my carbon monoxide detector went off, and I was able to ventilate the house before it was too late. It was a scary reminder of the importance of carbon monoxide detectors and proper ventilation.
