Before you even think about touching your chainsaw, it’s crucial to prepare properly. This isn’t just about gathering tools; it’s about ensuring safety and efficiency. A well-prepared Husqvarna chainsaw maintenance routine includes having the right parts and accessories ready.
What You’ll Need for the Job
Gathering all your supplies before starting makes the Husqvarna chainsaw chain replacement smooth and fuss-free.
- New Husqvarna Chainsaw Chain: This is the most important part! Ensure it’s the correct one for your specific Husqvarna chainsaw model.
- Husqvarna Chainsaw Bar: While you’re replacing the chain, it’s a good time to inspect your bar. Sometimes, a worn bar necessitates a chain replacement.
- Bar Nut Wrench or Screwdriver: This tool is specific to your Husqvarna chainsaw model. It’s often a combination tool that fits the bar nuts and sometimes the spark plug.
- Gloves: Protect your hands from sharp chain teeth and grease.
- Safety Glasses: Essential for protecting your eyes from flying debris or metal shavings.
- Cleaning Rag: To clean up sawdust and oil.
- Owner’s Manual: Always consult your Husqvarna chainsaw’s owner’s manual for model-specific instructions and specifications.
Selecting the Correct Chainsaw Chain Husqvarna
Choosing the right Husqvarna chainsaw parts chain is paramount for optimal performance and safety. Using the wrong chain can damage your saw, lead to poor cutting, and be a safety hazard.
Identifying Your Saw’s Chain Specifications
Your Husqvarna chainsaw will have specific chain requirements. You can find this information in a few places:
- Owner’s Manual: This is your primary resource for chain specifications.
- On the Bar: The bar itself often has the pitch and gauge stamped on it.
- On the Old Chain: The drive link of your old chain might have numbers indicating its specifications.
The key specifications to look for are:
- Pitch: This refers to the distance between the drive links. It’s measured from the center of one rivet to the center of the next, then divided by two. Common pitches are .325″, 3/8″, and .404″.
- Gauge: This is the thickness of the drive link that fits into the bar groove. Common gauges are .050″ (1.3mm) and .058″ (1.5mm).
- Number of Drive Links: This is the count of the drive links on your chain. This number must match your new chain exactly.
Why the Correct Chain Matters
- Performance: The correct chain cuts efficiently and smoothly.
- Durability: Using the right pitch and gauge prevents excessive wear on the bar, sprocket, and chain itself.
- Safety: An incorrect chain can jump off the bar, leading to serious injury. It can also cause the saw to bind or kickback more aggressively.
The Process: Step-by-Step Husqvarna Chainsaw Chain Installation
Now that you’re prepared, let’s dive into the actual process of how to change a chainsaw chain Husqvarna. This is a core part of Husqvarna chainsaw maintenance.
Step 1: Disengaging the Chain Brake and Ensuring Safety
- Engage the Chain Brake: Before you begin, always engage the chain brake. This prevents accidental chain movement.
- Turn Off the Chainsaw: Ensure the engine is completely off and cool.
- Wear Gloves and Safety Glasses: Protect yourself from sharp edges and debris.
Step 2: Loosening the Bar Nuts
Your Husqvarna chainsaw has nuts that hold the guide bar in place. These typically require a specific wrench or screwdriver.
- Locate the Bar Nuts: These are usually two or three nuts on the side of the chainsaw where the bar meets the body.
- Loosen the Nuts: Use your wrench to loosen these nuts. You don’t need to remove them completely at this stage, just loosen them enough to allow the bar to move.
Step 3: Adjusting Chain Tension (If Applicable)
Some Husqvarna models have a tool-less chain tensioning system. Others use a screw located on the side of the engine or near the bar.
- Tool-less Tensioner: If your saw has a knob or lever, you’ll usually loosen the bar nuts and then turn the tensioning knob to slacken the chain.
- Screw Tensioner: If there’s a screw, use your screwdriver to turn it counter-clockwise to loosen the chain. The purpose here is to create enough slack so you can easily remove the old chain and install the new one.
Step 4: Removing the Old Chain and Guide Bar
With the bar nuts loosened and the chain tension released, you can now slide the guide bar forward.
- Slide the Guide Bar: Gently push the guide bar towards the front of the chainsaw. This will give you enough slack to pull the old chain off.
- Remove the Old Chain: Carefully lift the old chain off the guide bar and away from the sprocket. Be mindful of the sharp teeth.
- Remove the Guide Bar: Once the chain is off, you can usually lift the guide bar completely away from the saw.
Step 5: Cleaning the Guide Bar and Sprocket
This is a critical step in Husqvarna chainsaw maintenance. A clean bar and sprocket ensure a smooth operation for the new chain.
- Inspect the Guide Bar: Check the groove for sawdust, debris, or packed-in grime. Use a rag to clean it out. Also, check for wear. If the edges of the bar groove are sharp or the bar rail is damaged, it might be time to replace the guide bar as well.
- Clean the Sprocket: The sprocket is the toothed wheel that drives the chain. Remove any debris or packed sawdust from around the sprocket.
Step 6: Installing the New Husqvarna Chainsaw Chain
This is where the Husqvarna chainsaw chain installation really begins.
- Position the Guide Bar: Place the guide bar back onto the chainsaw studs. Ensure the oiler hole in the bar aligns with the oiler feed on the saw.
- Place the New Chain: Drape the new Husqvarna chainsaw chain around the guide bar and into the bar groove. Crucially, pay attention to the direction of the cutting teeth. The “teeth” of the chain should all be pointing forward, away from the handles and towards the tip of the bar. Most chains have an arrow indicating the correct direction of rotation.
- Engage the Sprocket: Carefully fit the drive links of the new chain onto the engine’s drive sprocket. This might require a bit of wiggling and rotating the sprocket by hand.
Step 7: Adjusting Chain Tension (Initial Set)
Once the chain is on the bar and engaging the sprocket, you need to set the initial tension.
- Move the Guide Bar: Pull the guide bar forward, towards the front of the saw, to take up the slack.
- Tighten the Bar Nuts: Hand-tighten the bar nuts to hold the bar in place.
Step 8: Setting the Correct Husqvarna Chainsaw Chain Tension
Proper Husqvarna chainsaw chain tension is vital for safe and efficient cutting. Too loose, and the chain can derail. Too tight, and it can cause excessive wear and strain on the saw.
How to Achieve Correct Tension
- Check the Chain: With the bar nuts still slightly loose, use your gloved hand to pull the chain around the bar. It should move freely by hand, but there should be a slight drag.
- Tensioning Mechanism:
- Tool-less Tensioner: Locate the tensioning knob on your saw. Turn it clockwise to tighten the chain. You want the chain to be snug against the top of the bar but still allow you to move it by hand.
- Screw Tensioner: Use your screwdriver. Turn the tensioning screw clockwise to tighten the chain. Again, aim for a snug fit that you can still move by hand.
- The “Pull Test”: The classic test is to pull the chain down from the top of the bar. You should be able to pull it down slightly, but the drive links should still be seated in the bar groove, and the chain shouldn’t be sagging loosely. When you let go, the chain should stay in place.
- Tighten the Bar Nuts: Once you’ve achieved the correct tension, firmly tighten the bar nuts using your wrench. Re-check the chain tension after tightening the nuts, as they can sometimes shift the bar slightly.
Step 9: Final Check and Test Run
- Spin the Chain by Hand: With the brake off, spin the chain by hand again to ensure it moves freely and smoothly without any binding.
- Start the Saw: Start your Husqvarna chainsaw and let it idle for a few seconds.
- Engage the Chain Brake: Engage the chain brake.
- Check Chain Movement at Idle: The chain should not move on its own at idle. If it does, the chain is too tight.
- Disengage Brake and Test: Disengage the chain brake and briefly engage the throttle. Observe the chain. It should spin smoothly. Let it run for a few seconds, then disengage the throttle.
- Check Tension Again: After running for a short period, turn the saw off, let it cool slightly, and re-check the chain tension. It’s common for a new chain to stretch a bit after its initial run, so a slight adjustment might be necessary.
Maintaining Your Husqvarna Chainsaw Chain and Bar
Proper Husqvarna chainsaw maintenance extends the life of your chain and bar and ensures your saw performs at its best.
How to Keep Your Chain Sharp
A sharp chain cuts faster, uses less fuel, and reduces operator fatigue.
- Sharpening Tools: You’ll need a round file of the correct diameter for your chain’s pitch and a file guide. A flat file is also useful for bench sharpening or re-profiling.
- Sharpening Frequency: Sharpen your chain every time you refuel your saw, or whenever you notice a decrease in cutting performance.
- Sharpening Technique:
- Engage the Chain Brake: Always engage the brake when sharpening.
- Secure the Bar: Ensure the bar is stable.
- Identify the Start Point: Find the shortest cutter to use as a reference.
- File Angle: Use the file guide and hold the file at the correct angle (usually indicated in your manual or on the file guide).
- Filing Strokes: File from the inside of the cutter to the outside, using firm, consistent strokes. Typically, 8-10 strokes per cutter is sufficient.
- Maintain Evenness: Try to make each stroke consistent in pressure and angle. Count your strokes to ensure all cutters are sharpened to the same length.
- Depth Gauges: Check the depth gauges (the small “hump” in front of each cutter). If they are too high, they can prevent the cutter from biting properly. Use a flat file to gently lower them to the level of the depth gauge guide on your file guide or bar. Be careful not to over-file.
Lubrication is Key
Proper lubrication prevents premature wear and overheating.
- Bar and Chain Oil: Always use a good quality bar and chain oil. Never use regular motor oil, as it won’t adhere properly and can clog the oiler.
- Fill the Reservoir: Ensure the oil reservoir is full before starting work.
- Check Oiler Function: Periodically check that the oiler is working by holding the running saw (at a safe distance and angle) against a piece of light-colored wood or cardboard. You should see a fine spray of oil. If not, the oiler may be clogged.
Storing Your Chainsaw
Proper storage prevents damage and makes future Husqvarna chainsaw chain replacement easier.
- Cleanliness: Clean off any sawdust and debris before storing.
- Chain Protection: Apply a light coat of oil to the chain and bar to prevent rust. You can also use a chain guard.
- Dry Location: Store your chainsaw in a dry, protected environment.
Troubleshooting Common Husqvarna Chainsaw Chain Issues
Even with careful maintenance, you might encounter problems. Here are a few common issues and how to address them.
Chain Not Cutting Straight
- Cause: Unevenly sharpened cutters or a damaged guide bar.
- Solution: Sharpen all cutters consistently. Inspect the guide bar for wear or damage; replace if necessary.
Chain Slips Off the Bar
- Cause: Chain is too loose, or the bar groove is worn.
- Solution: Increase chain tension following the correct Husqvarna chainsaw chain tensioning procedure. Inspect the bar groove; if it’s wider than the drive links, replace the bar.
Saw Binds or Cuts Slowly
- Cause: Dull chain, chain tension is too tight, or insufficient lubrication.
- Solution: Sharpen the chain. Check and adjust chain tension. Ensure the bar and chain are adequately lubricated.
Chain Doesn’t Move When Throttle is Engaged
- Cause: The chain is too tight, causing excessive friction on the sprocket, or there’s an issue with the clutch or sprocket.
- Solution: Loosen the chain tension. If the problem persists, it might indicate a more serious mechanical issue requiring professional attention.
Frequently Asked Questions About Husqvarna Chainsaw Chain Replacement
Here are answers to some common questions regarding Husqvarna chainsaw chain replacement.
