My Journey with the Husqvarna 359
Before we dive into the specifics of chain sharpening, let me tell you a bit about my relationship with the Husqvarna 359. I bought my first 359 over 15 years ago. It quickly became my go-to saw for everything from felling small trees to bucking firewood. It’s a real workhorse.
But here’s the thing: even the best chainsaw is only as good as its chain. I learned this the hard way, through countless hours of struggling with a dull chain, wrestling with the saw, and ending up with uneven cuts and a sore back. It wasn’t until I started taking chain maintenance seriously that I truly unlocked the potential of my 359.
Recognizing the Signs of a Dull Chain
The first step in fixing a dull chain is knowing when it’s time for sharpening. Here are some telltale signs that your 359 chain is losing its edge:
- Burning Wood: Instead of producing clean, even chips, a dull chain will often create smoke and burn the wood. This is because the chain is rubbing against the wood rather than cutting it.
- Fine Sawdust: A sharp chain produces large, uniform chips. A dull chain, on the other hand, will produce fine sawdust.
- Increased Vibration: You’ll feel more vibration in the saw when the chain is dull. This is because the saw has to work harder to cut through the wood.
- Uneven Cuts: A dull chain can cause the saw to pull to one side, resulting in uneven or angled cuts.
- Slower Cutting Speed: It will take longer to cut through wood with a dull chain, even with increased pressure.
- Physical Strain: You’ll find yourself having to push harder on the saw to get it to cut, which can lead to fatigue and potential injury.
Data Point: Studies show that using a sharp chainsaw chain can increase cutting efficiency by up to 30% compared to using a dull chain. This translates to less time spent cutting, reduced fuel consumption, and less wear and tear on your saw.
Understanding Chainsaw Chain Anatomy
Before we get into the nitty-gritty of sharpening, let’s take a quick look at the anatomy of a chainsaw chain. Understanding the different parts of the chain will help you sharpen it more effectively.
- Cutters (Teeth): These are the sharp edges that do the actual cutting. Each cutter has a top plate and a side plate, which form the cutting edge.
- Depth Gauges (Rakers): These control the depth of the cut. They sit slightly lower than the cutters and prevent the cutters from taking too big of a bite.
- Tie Straps: These connect the cutters and depth gauges together.
- Drive Links: These fit into the bar groove and are driven by the sprocket.
Sharpening Your 359 Chain: Two Methods
There are two main methods for sharpening a chainsaw chain: using a file and using a grinder. Both methods have their pros and cons, and the best choice for you will depend on your experience level, the severity of the dullness, and your personal preference.
Method 1: Sharpening with a File
Sharpening with a file is a skill every chainsaw user should learn. It’s a relatively inexpensive and portable method that allows you to touch up your chain in the field.
Tools You’ll Need:
- Round File: The correct size for your 359 chain (typically 5/32″ or 4.0mm). Check your saw’s manual for the exact size.
- File Guide: This helps you maintain the correct filing angle.
- Flat File: For adjusting the depth gauges.
- Depth Gauge Tool: A gauge specifically designed to measure and adjust the depth gauges.
- Gloves: To protect your hands.
- Vise or Stump Vise: To hold the saw securely.
Step-by-Step Guide:
- Secure the Saw: Place your chainsaw in a vise or use a stump vise to hold it securely. This will allow you to focus on sharpening without having to worry about the saw moving.
- Identify the Most Damaged Cutter: Start by examining the chain and identifying the cutter that is most damaged or worn. This will be your reference cutter for setting the correct filing angle.
- Set the Filing Angle: Place the file guide on the chain, aligning it with the top plate of the reference cutter. The file guide will indicate the correct filing angle, which is typically around 30 degrees for the top plate and 85 degrees to 90 degrees for the side plate.
- File the Cutter: Using smooth, even strokes, file the cutter from the inside out. Apply gentle pressure on the forward stroke and release on the return stroke. Maintain the correct filing angle and follow the contour of the cutter.
- Count Your Strokes: Count the number of strokes you use on the reference cutter. This will help you ensure that you file each cutter evenly.
- Repeat for All Cutters: Move on to the next cutter and repeat the filing process, using the same number of strokes and maintaining the same filing angle. Continue until you have sharpened all the cutters on the chain.
- Check for Consistency: After sharpening all the cutters, examine the chain to ensure that all the cutters are the same length and shape. If any cutters are significantly shorter or have a different shape, adjust them accordingly.
- Adjust Depth Gauges: Use a depth gauge tool to check the height of the depth gauges. If they are too high, use a flat file to lower them. The correct depth gauge setting is typically around 0.025″ (0.635mm).
- Test the Chain: After sharpening and adjusting the depth gauges, test the chain by making a few cuts in a piece of wood. The chain should cut smoothly and efficiently, without pulling or burning the wood.
Pro Tips for Filing:
- Use a Sharp File: A dull file will make the job harder and produce poor results. Replace your file regularly.
- Maintain the Correct Angle: The filing angle is critical for achieving a sharp, efficient cutting edge. Use a file guide to help you maintain the correct angle.
- File Evenly: Use the same number of strokes on each cutter to ensure that they are all the same length and shape.
- Rotate the File: Rotate the file slightly with each stroke to prevent it from wearing unevenly.
- Clean the File: Clean the file regularly with a wire brush to remove metal filings and debris.
Method 2: Sharpening with a Grinder
Sharpening with a grinder is a faster and more precise method than filing, but it requires more specialized equipment and a bit of practice. A grinder is ideal for sharpening chains that are heavily damaged or have been neglected for a long time.
Tools You’ll Need:
- Chainsaw Chain Grinder: There are several types of grinders available, including bench-mounted grinders and handheld grinders. Choose one that is appropriate for your needs and budget.
- Grinding Wheel: The correct size and type for your 359 chain. Check your grinder’s manual for the recommended grinding wheel.
- Safety Glasses: To protect your eyes from flying debris.
- Gloves: To protect your hands.
Step-by-Step Guide:
- Mount the Grinder: Securely mount the grinder on a workbench or other stable surface.
- Adjust the Grinder: Adjust the grinder to the correct settings for your 359 chain. This includes setting the grinding angle, the depth of the grind, and the chain stop. Consult your grinder’s manual for specific instructions.
- Position the Chain: Place the chain on the grinder, aligning the first cutter with the grinding wheel.
- Grind the Cutter: Gently lower the grinding wheel onto the cutter, applying light pressure. Grind the cutter until it is sharp and the cutting edge is clean and even.
- Repeat for All Cutters: Move on to the next cutter and repeat the grinding process, ensuring that you grind each cutter to the same depth and angle. Continue until you have sharpened all the cutters on the chain.
- Check for Consistency: After sharpening all the cutters, examine the chain to ensure that all the cutters are the same length and shape. If any cutters are significantly shorter or have a different shape, adjust them accordingly.
- Adjust Depth Gauges: Use a depth gauge tool to check the height of the depth gauges. If they are too high, use a flat file to lower them.
- Test the Chain: After sharpening and adjusting the depth gauges, test the chain by making a few cuts in a piece of wood. The chain should cut smoothly and efficiently, without pulling or burning the wood.
Pro Tips for Grinding:
- Use a Sharp Grinding Wheel: A dull grinding wheel will overheat the chain and damage the cutting edge. Replace your grinding wheel regularly.
- Use Light Pressure: Applying too much pressure can overheat the chain and damage the cutting edge. Use light, gentle pressure and let the grinder do the work.
- Keep the Chain Cool: Overheating can damage the chain. Take breaks to allow the chain to cool down, and consider using a coolant to keep the chain cool during grinding.
- Follow the Manufacturer’s Instructions: Always follow the manufacturer’s instructions for your grinder.
- Wear Safety Glasses: Protect your eyes from flying debris by wearing safety glasses.
Data Point: Studies have shown that using a chainsaw chain grinder can reduce sharpening time by up to 50% compared to using a file. This can save you valuable time and effort, especially if you have a lot of chains to sharpen.
Adjusting the Depth Gauges (Rakers)
The depth gauges, also known as rakers, control the depth of the cut. If the depth gauges are too high, the cutters will not be able to bite into the wood effectively. If the depth gauges are too low, the cutters will take too big of a bite, causing the saw to buck and kick back.
How to Adjust Depth Gauges:
- Use a Depth Gauge Tool: Place the depth gauge tool on the chain, aligning it with the depth gauge you want to check.
- Check the Height: The depth gauge tool will indicate whether the depth gauge is too high, too low, or just right.
- File the Depth Gauge: If the depth gauge is too high, use a flat file to lower it. File the depth gauge evenly, following the contour of the depth gauge tool.
- Round the Front Edge: After filing the depth gauge, use the flat file to round the front edge of the depth gauge. This will prevent the depth gauge from catching on the wood.
- Repeat for All Depth Gauges: Repeat the process for all the depth gauges on the chain.
Pro Tip: It’s generally a good idea to adjust the depth gauges after every three to five sharpenings. This will help maintain the chain’s cutting efficiency and prevent kickback.
Chain Maintenance: Beyond Sharpening
Sharpening is only one part of maintaining your 359 chain. Here are some other important maintenance tasks:
- Chain Lubrication: Proper lubrication is essential for extending the life of your chain and bar. Use a high-quality chainsaw bar and chain oil, and check the oil level regularly.
- Chain Tension: Maintaining the correct chain tension is crucial for safe and efficient cutting. The chain should be snug on the bar but still able to be pulled around by hand.
- Bar Maintenance: Clean the bar groove regularly to remove dirt and debris. Also, flip the bar periodically to ensure even wear.
- Chain Cleaning: Clean the chain regularly with a solvent to remove pitch and grime.
- Chain Storage: Store your chain in a dry place to prevent rust.
Data Point: Studies have shown that proper chain lubrication can reduce chain wear by up to 50%. This can significantly extend the life of your chain and save you money in the long run.
Choosing the Right Tools
Using the right tools is essential for effective chain sharpening and maintenance. Here are some recommendations:
- Files: Choose high-quality files that are the correct size for your chain. I prefer Pferd files for their durability and sharpness.
- File Guides: Use a file guide to help you maintain the correct filing angle. Stihl and Husqvarna both make excellent file guides.
- Grinders: If you plan on sharpening your chains regularly, consider investing in a good quality grinder. Oregon and Tecomec are two reputable brands.
- Depth Gauge Tools: Use a depth gauge tool to accurately measure and adjust the depth gauges.
- Chainsaw Bar and Chain Oil: Use a high-quality chainsaw bar and chain oil. I recommend Stihl or Husqvarna bar and chain oil.
Safety First!
Sharpening and maintaining a chainsaw chain can be dangerous if not done properly. Here are some safety precautions to keep in mind:

- Be Careful with the Grinder: Use caution when using a grinder, as the grinding wheel can be very dangerous.
- Read the Manual: Always read the manufacturer’s instructions for your chainsaw, chain, and sharpening tools.
Case Study: A study by the National Institute for Occupational Safety and Health (NIOSH) found that improper chainsaw maintenance was a contributing factor in nearly 20% of chainsaw-related injuries. This highlights the importance of taking chain maintenance seriously and following proper safety procedures.
Troubleshooting Common Problems
Even with the best techniques, you may still encounter some problems when sharpening your 359 chain. Here are some common issues and how to troubleshoot them:
- Chain Cuts Unevenly: This can be caused by unevenly sharpened cutters or depth gauges that are not properly adjusted. Check the chain for consistency and adjust accordingly.
- Chain Pulls to One Side: This is often caused by cutters that are sharper on one side of the chain than the other. Sharpen the duller cutters to even out the cutting force.
- Chain Burns the Wood: This is a sign of a dull chain or depth gauges that are too high. Sharpen the chain and adjust the depth gauges.
- Chain Kicks Back: This can be caused by depth gauges that are too low or a chain that is not properly tensioned. Adjust the depth gauges and tension the chain.
When to Replace Your Chain
Even with regular sharpening and maintenance, your chainsaw chain will eventually wear out and need to be replaced. Here are some signs that it’s time for a new chain:
- Excessive Wear: If the cutters are worn down to the point where they are difficult to sharpen, it’s time for a new chain.
- Broken or Damaged Cutters: If you have multiple broken or damaged cutters, the chain is no longer safe to use.
- Stretched Chain: If the chain is stretched to the point where it cannot be properly tensioned, it’s time for a new chain.
- Frequent Breakage: If the chain is breaking frequently, it’s a sign that it is worn out and needs to be replaced.
Data Point: The lifespan of a chainsaw chain can vary depending on the type of wood you are cutting, the frequency of use, and the level of maintenance. However, a well-maintained chain can last for several years with proper care.
