Husqvarna 435 Chainsaw Chain Size: 5 Expert Tips for Precision

The Husqvarna 435 is a popular saw, known for its reliability and versatility. But to truly unlock its potential, you need to understand its chain requirements. I’ve seen too many folks struggle with the wrong chain, leading to poor cuts, kickback hazards, and unnecessary wear and tear on their equipment. So, let’s get this right.

1. Understanding the Stock Chain Specifications

The Husqvarna 435 typically comes equipped with a chain that is specifically designed to optimize its performance. Knowing these specifications is the first step to ensuring you’re using the right chain.

• Pitch: The pitch of a chain is the distance between any three consecutive rivets divided by two. The Husqvarna 435 generally uses a .325″ pitch chain. This is a common pitch for saws in this class, offering a good balance between cutting speed and durability. I’ve found this pitch to be particularly effective for hardwoods like oak and maple.
• Gauge: The gauge is the thickness of the drive links that fit into the guide bar groove. The Husqvarna 435 typically requires a .050″ gauge chain. Using the wrong gauge can lead to the chain not fitting properly on the bar, causing it to bind or fall off.
• Drive Links: The number of drive links determines the length of the chain. For a standard 16″ bar on the Husqvarna 435, you’ll usually need 66 drive links. Always double-check this number before purchasing a new chain. Count them if you have to! I once ordered a chain online without verifying the drive links and ended up with a chain that was too short. Lesson learned.

Takeaway: Know your numbers! Pitch (.325″), gauge (.050″), and drive links (typically 66 for a 16″ bar) are crucial for chain selection.

2. Identifying Your Specific Bar Length

While the Husqvarna 435 often comes with a 16″ bar, it can also accommodate other sizes, such as 14″ or even 18″. The bar length directly affects the number of drive links required.

• Measuring Your Bar: The bar length is usually stamped on the guide bar itself. Look near the base of the bar where it mounts to the saw. If you can’t find it, measure the usable cutting length of the bar, from the tip to where it meets the saw body.

• Matching Bar Length to Drive Links: Here’s a general guideline for Husqvarna 435:

  • 14″ bar: approximately 60 drive links
  • 16″ bar: approximately 66 drive links
  • 18″ bar: approximately 72 drive links

  These are approximate values. Always verify the correct number of drive links with your bar manufacturer or a knowledgeable dealer. I’ve seen variations depending on the bar type and chain manufacturer.

• Why This Matters: Using a chain with the wrong number of drive links is a safety hazard. A chain that’s too short won’t fit, and a chain that’s too long will be loose and prone to derailment.

Takeaway: Always match the number of drive links to your specific bar length. Don’t guess; verify.

3. Choosing the Right Chain Type for Your Needs

Chains aren’t one-size-fits-all. Different chain types are designed for different cutting tasks and wood types. Understanding these differences can significantly improve your cutting efficiency and the lifespan of your chain.

• Full Chisel Chains: These chains have square-cornered cutters that provide the fastest and most efficient cutting. They are ideal for clean wood and experienced users. However, they dull quickly if they come into contact with dirt or debris. I primarily use full chisel chains when felling trees in clean environments.
• Semi-Chisel Chains: These chains have rounded cutters that are more forgiving and durable than full chisel chains. They are a good all-around choice for general use, including cutting dirty or knotty wood. I often switch to a semi-chisel chain when processing firewood, as it’s more resistant to dulling from occasional contact with the ground.
• Low-Kickback Chains: These chains are designed with safety in mind. They feature guard links that reduce the risk of kickback, a dangerous phenomenon where the saw suddenly jumps back towards the operator. These chains are a good choice for beginners or anyone who prioritizes safety. While they cut slightly slower than full or semi-chisel chains, the added safety is well worth it.
• Ripping Chains: These chains are specifically designed for cutting wood along the grain, such as when milling lumber. They have a different cutter angle than standard chains, which allows them to cut more efficiently in this direction. I’ve used ripping chains with my Husqvarna 435 and an Alaskan mill attachment to create lumber from fallen trees.

Personal Story: I remember one time I was helping a friend clear some storm-damaged trees. He was using a full chisel chain to cut through some dirty, knotty wood, and he was constantly having to stop and sharpen the chain. I suggested he switch to a semi-chisel chain, and the difference was night and day. He was able to cut through the wood much faster and with less effort, and the chain stayed sharp much longer.

Takeaway: Choose the chain type that best suits your cutting needs and experience level. Full chisel for speed and clean wood, semi-chisel for general use and durability, low-kickback for safety, and ripping chains for milling.

4. Mastering Chain Maintenance and Sharpening

Even the best chain will perform poorly if it’s not properly maintained. Regular sharpening and maintenance are essential for safety, efficiency, and extending the life of your chain.

• Sharpening Frequency: How often you need to sharpen your chain depends on the type of wood you’re cutting and how often you use the saw. As a general rule, sharpen your chain whenever it starts to cut slower, produces fine sawdust instead of chips, or pulls to one side. I typically sharpen my chains after every few tanks of fuel, or more often if I’m cutting dirty or hard wood.

• Sharpening Tools: You can sharpen your chain with a variety of tools, including:

  • Round File and Guide: This is the most common and affordable method. Use a round file of the correct diameter for your chain’s pitch (typically 5/32″ for a .325″ pitch chain). A filing guide helps you maintain the correct angle and depth.
  • Electric Chain Sharpener: These sharpeners are faster and more precise than hand filing, but they are also more expensive.
  • Bar-Mounted Sharpener: These sharpeners attach directly to the saw bar and allow you to sharpen the chain without removing it. They are convenient for quick touch-ups in the field.

• Sharpening Technique: The key to sharpening a chain is to maintain the correct angle and depth on each cutter. Use consistent strokes and follow the manufacturer’s instructions for your sharpening tool. I always start by sharpening the shortest cutter, then use that as a guide for sharpening the rest of the cutters.

• Depth Gauge Maintenance: The depth gauges (also called rakers) are the small metal tabs in front of each cutter. They control how much wood the cutter takes with each pass. As you sharpen the cutters, the depth gauges will become relatively higher. You need to file them down occasionally to maintain the correct depth gauge setting. Use a flat file and a depth gauge tool to ensure you’re filing them to the correct height.
• Chain Cleaning and Lubrication: Keep your chain clean and well-lubricated. Use bar and chain oil specifically designed for chainsaws. Clean the chain regularly with a brush and solvent to remove dirt and debris.

Case Study: I once worked on a logging project where the crew was experiencing unusually high chain wear. After investigating, I discovered that they were not properly maintaining the depth gauges. As a result, the cutters were taking too big of a bite, which was causing excessive strain on the chain. By properly filing the depth gauges, we were able to significantly reduce chain wear and improve cutting efficiency.

Takeaway: Regular sharpening and maintenance are essential for chain performance and longevity. Learn to sharpen your chain properly and maintain the depth gauges. Keep the chain clean and well-lubricated.

5. Safety First: Kickback Prevention and Safe Cutting Practices

Chainsaws are powerful tools, but they can also be dangerous. Kickback is one of the most common causes of chainsaw injuries. Understanding how to prevent kickback and practicing safe cutting techniques are essential for protecting yourself and others.

• Understanding Kickback: Kickback occurs when the upper tip of the chainsaw bar contacts an object, causing the saw to suddenly jump back towards the operator. This can happen in a fraction of a second and can result in serious injury.

• Kickback Prevention Tips:

  • Use a low-kickback chain: These chains have guard links that reduce the risk of kickback.
  • Maintain proper chain tension: A loose chain is more likely to kick back.
  • Avoid pinching the bar: Pinching occurs when the wood closes in on the bar, trapping the chain. This can cause the saw to kick back. Use wedges to keep the cut open.
  • Be aware of the tip of the bar: Avoid using the tip of the bar to make cuts.
  • Hold the saw firmly with both hands: This will give you better control of the saw and help you resist kickback.
  • Stand to the side of the cut: This will help you avoid being hit by the saw if it kicks back.
  • Keep your chain sharp: A dull chain is more likely to kick back.
  • Never cut above shoulder height: This puts you in a vulnerable position and increases the risk of kickback.

• Safe Cutting Practices:

  • Wear appropriate safety gear: This includes a helmet, eye protection, hearing protection, gloves, chaps, and boots.
  • Inspect the saw before each use: Check the chain tension, oil level, and all safety features.
  • Start the saw on the ground: Never drop-start a chainsaw.
  • Clear the work area of obstacles: Remove any branches, rocks, or other objects that could trip you or interfere with your cutting.
  • Plan your cuts: Think about where the wood will fall and make sure there is a clear escape route.
  • Use proper felling techniques: If you are felling trees, use proper felling techniques to control the direction of the fall.
  • Never cut alone: Always have someone nearby in case of an emergency.
  • Take breaks: Chainsawing can be physically demanding. Take frequent breaks to avoid fatigue.

Personal Story: I once witnessed a near-fatal chainsaw accident when a fellow logger was felling a tree. He didn’t properly assess the lean of the tree, and when he made the back cut, the tree kicked back and struck him in the head. He was wearing a helmet, which undoubtedly saved his life, but he still suffered a serious concussion. This incident reinforced the importance of always following safe cutting practices.

Takeaway: Safety is paramount. Understand the risks of chainsaw use, practice kickback prevention techniques, and always wear appropriate safety gear. Never compromise on safety.

Bonus Tip: Chain Tensioning for Optimal Performance

Proper chain tension is critical for safe and efficient cutting. 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, causing premature wear and tear.

• Checking Chain Tension: To check the chain tension, pull the chain away from the bar in the middle of the bar’s underside. You should be able to pull the chain out about 1/8″ to 1/4″. If you can pull it out further, the chain is too loose. If you can’t pull it out at all, the chain is too tight.
• Adjusting Chain Tension: Most chainsaws have a tensioning screw located on the side of the saw near the bar. To adjust the tension, loosen the bar nuts slightly, then turn the tensioning screw until the chain is at the correct tension. Tighten the bar nuts securely after adjusting the tension.

• Tensioning Considerations:

  • New Chains: New chains tend to stretch slightly during the first few uses. Check the tension frequently during the break-in period and adjust as needed.
  • Temperature: Chain tension can change with temperature. Check the tension before each use, especially in cold weather.
  • Wood Type: Hardwoods require slightly tighter chain tension than softwoods.

Takeaway: Regularly check and adjust your chain tension to ensure optimal performance and safety.
