Types of Chainsaw Chains: 5 Key Tips for Arborists

1. Understanding Chain Anatomy: The Foundation of Your Choice

Before we delve into specific chain types, it’s essential to understand the basic anatomy of a chainsaw chain. This knowledge forms the bedrock of making informed decisions.

Cutters: These are the teeth that actually do the cutting. They come in various shapes and sizes, each designed for different types of wood and cutting conditions.
Tie Straps: These connect the cutters and drive links, providing structural integrity to the chain.
Drive Links: These fit into the guide bar groove and are driven by the chainsaw’s sprocket, propelling the chain around the bar.
Depth Gauges (Rakers): These control the depth of each cut, preventing the cutters from digging in too aggressively.

Over the years, I’ve noticed that many arborists overlook the importance of depth gauge maintenance. A properly set depth gauge ensures smooth, efficient cutting and reduces the risk of kickback. I make it a habit to check and adjust my depth gauges every time I sharpen my chain. I use a depth gauge tool and flat file to get the correct height.

Data Point: According to a study by Oregon Products, proper depth gauge maintenance can improve cutting efficiency by up to 20% and reduce the risk of kickback by 30%.

2. Identifying the Right Chain Type for the Job: A Practical Guide

Choosing the correct chain type is paramount for efficiency and safety. Here are some common types and their ideal applications:

Full Chisel Chains: These chains have square-cornered cutters that provide the fastest and most efficient cutting in clean, softwood. However, they are more prone to kickback and dull quickly in dirty or hardwood.
- Ideal For: Felling clean softwood trees, limbing in controlled environments.
Semi-Chisel Chains: These chains have rounded-corner cutters that are more forgiving in dirty or hardwood. They are more durable than full chisel chains but cut slightly slower.
- Ideal For: General purpose cutting, felling hardwood trees, working in dirty or abrasive conditions.
Low-Profile Chains (Micro-Chisel): These chains have smaller cutters and a shallower cutting angle, making them safer and easier to control. They are ideal for beginners and those who prioritize safety over speed.
- Ideal For: Light pruning, small tree removal, novice users.
Skip Chains: These chains have fewer cutters, which reduces the load on the chainsaw and allows for longer bars. They are often used for milling or cutting large diameter logs.
- Ideal For: Milling, cutting large diameter logs, chainsaws with limited power.
Carving Chains: These specialty chains feature a narrow profile and specialized cutters designed for intricate carving work.
- Ideal For: Wood carving, creating detailed sculptures.
Ripping Chains: These chains are designed to cut with the grain of the wood, rather than across it. They have a different cutter angle and are used in chainsaw mills to make lumber.
- Ideal For: Milling logs into lumber.

Personal Story: I once worked on a project where we were felling a large number of oak trees in a particularly dirty environment. Initially, we used full chisel chains, but they were dulling incredibly fast, and we were spending more time sharpening than cutting. Switching to semi-chisel chains made a world of difference. Our production increased, and we spent less time on maintenance.

Expert Quote: “Choosing the right chain type is like choosing the right tool for any job. It can make the difference between a successful outcome and a frustrating experience.” – Mark Johnson, Certified Arborist

3. Understanding Chain Pitch and Gauge: Ensuring Compatibility

Chain pitch and gauge are critical specifications that determine compatibility with your chainsaw and guide bar.

Pitch: The distance between three consecutive rivets on the chain, divided by two. Common pitches are 0.325″, 3/8″, and 0.404″.
Gauge: The thickness of the drive links, which must match the groove width of the guide bar. Common gauges are 0.050″, 0.058″, and 0.063″.

Using the wrong pitch or gauge can damage your chainsaw and guide bar, and it can also be dangerous. Always consult your chainsaw’s manual or the guide bar for the correct specifications.

Actionable Tip: Before purchasing a new chain, double-check the pitch and gauge stamped on your guide bar. This will ensure compatibility and prevent costly mistakes.

4. Sharpening Techniques: Maintaining Peak Performance

A sharp chain is a safe chain. A dull chain forces you to apply more pressure, increasing the risk of kickback and fatigue. Regular sharpening is essential for maintaining peak performance and extending the life of your chain.

Tools: You’ll need a round file, a file guide, a flat file, and a depth gauge tool.
Technique: Use the round file to sharpen each cutter, following the original angle and depth. Use the file guide to maintain consistency. Use the flat file to adjust the depth gauges.
Frequency: Sharpen your chain every time you refuel, or more often if you notice it’s cutting slowly or producing fine sawdust instead of chips.

Personal Experience: I used to dread sharpening my chains, but I realized that investing in a good quality file guide made a huge difference. It helped me maintain consistent angles and depths, resulting in a sharper, more efficient chain. Now, I actually enjoy the process!

Step-by-Step Instructions:

Secure the chainsaw in a vise.
Select the correct size round file for your chain pitch.
Place the file guide on the chain, aligning it with the cutter.
File each cutter, using smooth, consistent strokes.
Maintain the original angle and depth of the cutter.
Check the depth gauges and adjust them as needed using the flat file and depth gauge tool.
Repeat for all cutters on the chain.

Addressing Challenges: One common challenge is maintaining a consistent angle while sharpening. Using a file guide can help, but it also takes practice. Don’t be afraid to experiment and find what works best for you.

Data Point: According to a study by Stihl, a properly sharpened chain can increase cutting speed by up to 50% and reduce fuel consumption by 20%.

5. Chain Maintenance: Extending the Life of Your Investment

Proper chain maintenance is crucial for extending the life of your chain and preventing costly repairs.

Actionable Tip: Create a chain maintenance checklist and follow it religiously. This will help you stay on top of your maintenance and prevent costly problems down the road.

Advanced Considerations for Arborists

Optimizing Chain Selection Based on Tree Species and Condition

Beyond the basic types of chains, arborists should consider the specific properties of the wood they are cutting. Different tree species have varying densities, grain patterns, and resin content, which can significantly impact chain performance.

Hardwoods (Oak, Maple, Hickory): These dense woods require durable chains with aggressive cutting angles. Semi-chisel or even specialized hardwood chains are recommended. Ensure your chainsaw has sufficient power to handle the increased cutting resistance.
Softwoods (Pine, Fir, Spruce): Softwoods are generally easier to cut, making full chisel chains a viable option for faster cutting speeds. However, be mindful of resin buildup, which can dull the chain quickly.
Dead or Decaying Wood: This type of wood is often abrasive and can contain hidden debris like nails or rocks. Use a more durable chain like a semi-chisel and be prepared to sharpen it frequently. Consider using a metal detector to identify any hidden metal objects.
Frozen Wood: Cutting frozen wood can be extremely challenging. Use a chain specifically designed for frozen conditions, which typically features a harder steel and a more aggressive cutting angle.

Personal Insight: I once attempted to fell a large, dead oak tree with a full chisel chain. The chain dulled almost immediately due to the abrasive nature of the decaying wood. After switching to a semi-chisel chain, the cutting process became significantly more efficient, and the chain held its edge much longer.

Workflow Optimization for Chain Management

Efficient chain management can significantly reduce downtime and improve productivity. Consider implementing the following strategies:

Chain Rotation: Have multiple chains on hand and rotate them regularly. This allows you to sharpen one chain while using another, minimizing downtime.
Designated Chain Storage: Store chains in a designated area, protected from dirt, moisture, and damage. Use chain cases or bags to keep them organized and prevent tangling.
Sharpening Station: Set up a dedicated sharpening station with all the necessary tools and equipment. This will make the sharpening process more efficient and enjoyable.
Chain Tracking: Keep track of the usage and sharpening history of each chain. This will help you identify chains that are nearing the end of their lifespan and need to be replaced.

Data-Backed Content: A study by the Forest Resources Association found that implementing a chain rotation and maintenance program can reduce chain-related downtime by up to 25%.

Sustainable Timber Selection and its Impact on Chain Wear

As arborists, we have a responsibility to promote sustainable forestry practices. Choosing sustainably sourced timber not only benefits the environment but can also impact chain wear.

Source Certification: Look for timber that is certified by organizations like the Forest Stewardship Council (FSC). This ensures that the timber has been harvested responsibly and sustainably.
Wood Density: Consider the density of the wood when selecting timber. Denser woods require more durable chains and more frequent sharpening.
Wood Condition: Avoid using timber that is damaged, diseased, or contains hidden debris. This can significantly increase chain wear and the risk of accidents.

Original Research: In my own experience, using sustainably sourced timber from well-managed forests has resulted in less chain wear compared to timber from unknown sources. This is likely due to the better quality control and the absence of hidden debris in sustainably sourced timber.
