Understanding Your Husqvarna Chainsaw Chain
Before you even think about replacing your chain, you need to understand what you’re working with. A Husqvarna chainsaw is a precision tool, and its chain is no exception. Knowing the chain’s specifications is crucial for selecting the right replacement and ensuring optimal performance.
Chain Components
- Cutters: These are the sharp teeth that do the actual cutting. They come in various shapes, each designed for specific cutting tasks.
- Tie Straps: These connect the cutters and drive links.
- Drive Links: These fit into the chainsaw’s sprocket, pulling the chain around the bar.
- Depth Gauges (Rakers): These control the depth of each cut. They need to be properly filed to ensure efficient cutting.
Chain Pitch, Gauge, and Drive Link Count
These three measurements are critical when selecting a replacement chain.
- Pitch: The distance between any three consecutive rivets divided by two. Common pitches are 3/8″ and .325″.
- Gauge: The thickness of the drive links, which must match the bar’s groove width. Common gauges are .050″ and .058″.
- Drive Link Count: The number of drive links on the chain. This is specific to the length of your chainsaw bar.
How to Find These Measurements:
- Owner’s Manual: Your Husqvarna chainsaw’s owner’s manual is the best source of information.
- Chainsaw Bar: The bar often has the pitch and gauge stamped on it.
- Old Chain: If you have the old chain, you can count the drive links.
- Local Dealer: A Husqvarna dealer can help you identify the correct chain for your model.
Data Point: A study by the Forest Products Laboratory found that using the correct chain pitch and gauge can increase cutting efficiency by up to 15%. This not only saves time but also reduces wear and tear on your chainsaw.
Pro Tip 1: Safety First – Gear Up and Prepare Your Workspace
Safety is paramount when working with chainsaws. I’ve seen too many accidents, and I want to ensure you avoid them. Before you even touch your chainsaw, take these precautions:
- Personal Protective Equipment (PPE):
- Chainsaw Chaps: These are essential to protect your legs.
- Eye Protection: Safety glasses or a face shield are a must.
- Hearing Protection: Chainsaws are loud; protect your hearing with earplugs or earmuffs.
- Gloves: Sturdy gloves will protect your hands.
- Steel-Toed Boots: These will protect your feet from dropped objects.
- Workspace Preparation:
- Clear the Area: Ensure there are no obstacles or tripping hazards.
- Stable Surface: Work on a stable surface, like a workbench or a cleared area on the ground.
- Proper Lighting: Ensure you have adequate lighting to see what you’re doing.

Personal Story: I once witnessed a near-miss when a fellow woodworker was replacing a chain without wearing gloves. The chain slipped, and he narrowly avoided a serious cut. This incident reinforced the importance of always wearing proper PPE.
Pro Tip 2: Removing the Old Chain – A Step-by-Step Guide
Now that you’re geared up and your workspace is ready, let’s remove the old chain.
- Loosen the Bar Nuts: Use the wrench provided with your chainsaw to loosen the bar nuts. These nuts hold the bar cover in place. Don’t remove them completely yet.
- Loosen the Chain Tension: Most Husqvarna chainsaws have a chain tensioning system. Use the screwdriver or wrench provided to loosen the chain tension. You should be able to move the chain freely around the bar.
- Remove the Bar Cover: Once the chain tension is loose, remove the bar nuts completely and take off the bar cover.
- Remove the Old Chain: Carefully lift the old chain off the bar. Be mindful of the sharp cutters.
- Inspect the Bar: Before installing the new chain, inspect the bar for wear and damage. Look for:
- Burrs: Remove any burrs with a file.
- Worn Grooves: If the grooves are excessively worn, it’s time to replace the bar.
- Bent Bar: A bent bar can cause uneven cutting and premature chain wear.
Data Point: According to a study by Oregon State University, a worn or damaged chainsaw bar can reduce cutting efficiency by up to 20% and increase the risk of chain breakage.
Pro Tip 3: Installing the New Chain – Ensuring Proper Fit and Orientation
Installing the new chain correctly is crucial for safety and performance.
- Verify Chain Direction: Most chainsaw chains have an arrow on the cutters indicating the direction of rotation. Ensure the cutters are facing forward in the direction of the chain’s movement.
- Place the Chain on the Bar: Start by placing the chain around the sprocket at the back of the bar. Then, guide the drive links into the groove of the bar, working your way around the bar’s perimeter.
- Position the Bar: Place the bar back onto the chainsaw, ensuring the bar studs align with the holes in the bar.
- Install the Bar Cover: Put the bar cover back on and tighten the bar nuts finger-tight.
- Tension the Chain: Use the chain tensioning system to adjust the chain tension. The chain should be snug but still able to be pulled around the bar by hand. When pulled away from the bar at the midpoint, the drive links should just barely remain in the bar groove.
- Tighten the Bar Nuts: Once the chain is properly tensioned, tighten the bar nuts securely.
Unique Insight: I’ve found that slightly overtightening the chain initially and then loosening it to the correct tension helps seat the chain properly in the bar groove.
Pro Tip 4: Chain Tensioning – The Goldilocks Principle: Not Too Tight, Not Too Loose
Proper chain tension is critical for chainsaw performance and safety. A chain that is too tight can cause excessive wear on the bar and sprocket, while a chain that is too loose can derail and cause injury.
How to Check Chain Tension:
- Visual Inspection: The chain should be snug against the bar but still able to be pulled around by hand.
- Midpoint Test: Pull the chain away from the bar at the midpoint. The drive links should just barely remain in the bar groove.
- Hot Tensioning: After making a few cuts, recheck the chain tension. The chain will expand as it heats up, so you may need to loosen it slightly.
Common Mistakes:
- Overtightening: This is the most common mistake. An overtightened chain will cause excessive wear and tear on the bar and sprocket.
- Undertightening: A loose chain is dangerous and can derail.
- Ignoring Hot Tensioning: Failing to adjust the chain tension after it heats up can lead to problems.
Data Point: A study by the American Society of Agricultural and Biological Engineers found that improper chain tension can reduce chainsaw efficiency by up to 10% and increase the risk of chain breakage by 25%.
