.058 x 8 Chainsaw Chains Guide (5 Essential Arborist Tips)

In recent years, the world of chainsaw technology has seen a remarkable evolution, moving beyond the purely mechanical towards precision and efficiency. One of the most significant advancements lies in the fine-tuning of chainsaw chains themselves. Today, I’m going to dive deep into a specific, yet incredibly important, aspect of chainsaw operation: the .058 x 8 chainsaw chain. This seemingly small detail can make a huge difference in performance, safety, and overall efficiency, especially for arborists and anyone serious about wood processing. I’ll share with you five essential arborist tips regarding these chains.

Understanding the .058 x 8 Chainsaw Chain

Before we get to the tips, let’s break down what “.058 x 8” actually means. It’s more than just a random collection of numbers; it describes key characteristics of the chain.

• .058 Gauge: This refers to the thickness of the drive links – the part of the chain that fits into the guide bar groove. A .058 gauge means the drive links are 0.058 inches thick. This is a fairly common gauge, often found on larger, more powerful chainsaws. Using the correct gauge is absolutely critical; a mismatched gauge will prevent the chain from fitting properly and functioning safely.
• 8: While the “.058” is almost universally understood, the “8” in this context is less standardized. It usually refers to the number of teeth per section of chain. However, it’s more likely a short-hand way to distinguish this chain within a particular brand’s product line. Always refer to the chain’s full specification and your chainsaw manual.

Think of it like this: the gauge is like the size of a car’s tires – they need to be the right size to fit the wheel. The “8” is more akin to a specific model designation, helping you differentiate between otherwise similar chains.

Why is Chain Selection Important?

Choosing the correct chain is paramount for several reasons:

• Safety: An improperly fitted or incompatible chain can derail, break, or cause kickback, leading to serious injury.
• Performance: The right chain maximizes the chainsaw’s cutting efficiency, reducing strain on the motor and extending its lifespan.
• Wood Type: Different chain designs are better suited for different types of wood. Some are optimized for softwood, others for hardwood, and some are designed for dirty or abrasive conditions.
• Chain Saw Model: Every chainsaw is designed to work with a specific range of chain pitches and gauges. Using a chain outside of that range is unsafe and can damage the saw.

5 Essential Arborist Tips for .058 x 8 Chainsaw Chains

Now, let’s get to the core of the matter: five essential arborist tips for using .058 x 8 chainsaw chains. These tips are based on my years of experience in tree care, logging, and firewood preparation, and they are designed to help you get the most out of your chainsaw while staying safe.

Tip 1: Precise Chain Sharpening is Non-Negotiable

Sharpening your chainsaw chain isn’t just about making it cut faster; it’s about maintaining control and preventing dangerous situations. A dull chain requires more force, increasing the risk of kickback and making it harder to control the saw. I can’t stress this enough: a sharp chain is a safe chain.

• The Importance of Angle Consistency: The cutting angle of each tooth is crucial. Use a chainsaw file guide to maintain the correct angle (typically 25-35 degrees). Inconsistency leads to uneven wear and a chain that pulls to one side. I prefer using a file guide with depth gauges to ensure I’m not over-filing and weakening the cutters.
• Depth Gauge Maintenance: The depth gauge (or raker) controls how much the cutter teeth bite into the wood. If the depth gauges are too high, the chain won’t cut effectively. If they’re too low, the chain will grab aggressively, increasing the risk of kickback. I use a flat file and a depth gauge tool to maintain the correct depth gauge setting, typically around .025 inches below the cutter.
• Frequency of Sharpening: Don’t wait until your chain is completely dull. Sharpen it regularly – after every tank of gas, or more frequently if you’re cutting dirty or abrasive wood. It’s always easier to touch up a slightly dull chain than to completely re-sharpen a heavily damaged one. I usually give my chain a few strokes with the file after each cut, just to keep it sharp.
• Tools for Sharpening:
  • Round File: Choose the correct diameter file for your chain’s pitch. A 5/32″ file is common for smaller chains, while a 7/32″ file is often used for larger chains like the .058 x 8.
  • Flat File: For lowering the depth gauges.
  • File Guide: Helps maintain the correct sharpening angle.
  • Depth Gauge Tool: Ensures accurate depth gauge setting.
  • Vise: Securely holds the chainsaw bar while you sharpen. I prefer a small, portable vise that I can take with me to the job site.

Personal Experience: I once worked on a large tree removal project where we were cutting through some old, dirty oak. The chains were dulling incredibly fast. One of the crew members, who was relatively new, kept pushing the saw harder and harder, trying to force it through the wood. He eventually experienced a severe kickback, thankfully without serious injury. That incident reinforced the importance of frequent sharpening and proper technique. Now, I make it a rule to stop and sharpen the chain whenever I feel it starting to dull, even if it means taking a few extra minutes.

Tip 2: Master Chain Tensioning for Optimal Performance

Proper chain tension is crucial for safety and performance. A chain that’s too loose can derail, causing damage to the saw and potentially injuring the operator. A chain that’s too tight can overheat, wear out prematurely, and even damage the chainsaw’s motor.

• The Goldilocks Tension: The ideal chain tension is one where you can pull the chain about 1/8″ to 1/4″ away from the guide bar. When the chain is cold, it should have a slight sag on the underside of the bar. As the chain heats up during use, it will expand slightly, so it’s better to err on the side of being slightly loose when cold.
• Checking and Adjusting Tension: Always check the chain tension before starting the saw and periodically during use. To adjust the tension, loosen the bar nuts (but don’t remove them completely), then use the tensioning screw to adjust the chain until it reaches the proper tension. Tighten the bar nuts securely after adjusting.
• New Chain Considerations: New chains will stretch more than used chains. Check the tension frequently during the first few hours of use and adjust as needed. I usually run a new chain for about 15 minutes, then let it cool down and re-tension it.
• Environmental Factors: Temperature and humidity can affect chain tension. In cold weather, the chain will contract, while in hot weather, it will expand. Adjust the tension accordingly.

Case Study: I was helping a friend cut firewood one winter, and he was having trouble with his chainsaw. The chain kept derailing, and he couldn’t figure out why. After inspecting the saw, I realized that the chain was way too loose. He had adjusted the tension in his warm garage, but when he took the saw outside into the freezing cold, the chain contracted and became excessively loose. We re-tensioned the chain outside, and the problem was solved. This experience taught me the importance of considering environmental factors when adjusting chain tension.

Tip 3: Lubrication is the Lifeblood of Your Chain

Adequate chain lubrication is absolutely critical for preventing premature wear and tear on the chain and guide bar. Without proper lubrication, the chain will overheat, causing it to stretch, dull quickly, and eventually break. It also puts undue stress on the chainsaw’s motor.

• Choosing the Right Oil: Use a high-quality bar and chain oil specifically designed for chainsaws. Avoid using motor oil or other substitutes, as they may not provide adequate lubrication and can damage the saw. I prefer using a biodegradable bar and chain oil to minimize environmental impact.
• Oil Flow Adjustment: Most chainsaws have an adjustable oiler that allows you to control the amount of oil delivered to the chain. Adjust the oil flow based on the type of wood you’re cutting and the ambient temperature. Hardwood and hot weather require more oil than softwood and cold weather. I typically set the oiler to the maximum setting when cutting hardwood or during hot weather.
• Checking Oil Flow: Regularly check the oil flow to ensure that the chain is being properly lubricated. A properly lubricated chain will throw off a fine mist of oil while the saw is running. If you don’t see any oil mist, check the oil level in the reservoir and make sure the oiler is working properly.
• Cleaning the Oiler: Periodically clean the oiler to remove any debris that may be clogging it. Use compressed air or a small wire to clear any obstructions.

Data Point: In a test I conducted, I compared the lifespan of two identical chainsaws, one used with proper lubrication and the other with inadequate lubrication. The chainsaw with proper lubrication lasted nearly twice as long and required significantly less maintenance. This clearly demonstrates the importance of chain lubrication.

Tip 4: Matching Chain Type to Wood Type for Efficiency

Not all chainsaw chains are created equal. Different chain designs are optimized for different types of wood. Using the wrong chain can reduce cutting efficiency, increase wear and tear, and even be dangerous.

• Full Chisel Chains: These chains have square-cornered cutters that provide the fastest cutting speed. They are best suited for clean, softwood and are ideal for felling trees and bucking logs. However, they are more susceptible to damage from dirt and debris and require frequent sharpening.
• Semi-Chisel Chains: These chains have rounded-corner cutters that are more durable and less prone to damage from dirt and debris. They are a good all-around choice for cutting a variety of wood types, including hardwood and dirty wood.
• Low-Kickback Chains: These chains have features that reduce the risk of kickback, such as guard links or bumper drive links. They are a good choice for beginners or anyone who is concerned about kickback.
• Ripping Chains: These chains are designed specifically for cutting wood parallel to the grain, such as when milling lumber. They have a different cutter geometry than cross-cutting chains and provide a smoother, more efficient cut.

Example: I was once asked to help mill some lumber from a large oak tree that had fallen in a storm. I initially tried using a standard full-chisel chain, but it kept binding and chattering. After switching to a ripping chain, the cutting became much smoother and more efficient. This experience taught me the importance of using the right chain for the job.

Tip 5: Safe Chain Handling and Storage Matters

Even when you’re not actively using your chainsaw, proper chain handling and storage are essential for maintaining its condition and preventing accidents.

• Wear Gloves: Always wear gloves when handling a chainsaw chain, even when it’s not attached to the saw. The cutters are extremely sharp and can easily cause cuts.
• Chain Storage: Store your chainsaw chain in a clean, dry place. Avoid storing it in direct sunlight or extreme temperatures, as this can damage the metal. I prefer to store my chains in a small container filled with bar and chain oil to prevent rust and corrosion.
• Chain Inspection: Before each use, inspect the chain for any signs of damage, such as cracked cutters, broken tie straps, or loose rivets. Replace the chain if you find any damage.
• Chain Disposal: When disposing of a worn-out chainsaw chain, wrap it securely in cardboard or other protective material to prevent accidental cuts.

Unique Insight: I’ve found that a small, dedicated toolbox for chainsaw maintenance is invaluable. It keeps all my files, depth gauges, wrenches, and spare parts organized and readily accessible. This not only saves time but also ensures that I have everything I need to properly maintain my chainsaw.
