Understanding these specifications is the first step in choosing the right chain.
Pro Tip 1: Decoding Chain Specifications
The first pro tip is to understand the three critical specifications of a chainsaw chain: pitch, gauge, and drive link count. These aren’t just numbers; they’re the key to a perfectly matched chain for your Husqvarna 450 X-Torq.
Pitch
The pitch is the distance between any three consecutive rivets on the chain, divided by two. It’s usually expressed in inches. The Husqvarna 450 X-Torq commonly uses a .325″ or 3/8″ pitch chain. Using the correct pitch ensures the chain fits properly on the sprocket and bar. Using the wrong pitch can lead to chain slippage, damage to the sprocket, and inefficient cutting.
How to Determine the Pitch:
- Check Your Saw’s Manual: This is the most reliable source.
- Measure: If the manual is unavailable, measure the distance between three rivets and divide by two.
- Consult a Dealer: Your local Husqvarna dealer can quickly identify the correct pitch.
Gauge
The gauge refers to the thickness of the drive links – the part of the chain that fits into the guide bar groove. It’s also expressed in inches or millimeters. Common gauges for the Husqvarna 450 X-Torq are .050″ (1.3 mm) and .058″ (1.5 mm). Using the correct gauge is crucial for a secure fit within the guide bar. If the gauge is too small, the chain will wobble and cut poorly. If it’s too large, it won’t fit at all.
How to Determine the Gauge:
- Check Your Saw’s Manual: Again, the manual is your best friend.
- Use a Gauge Tool: A simple gauge tool can quickly and accurately measure the gauge of your chain.
- Look for Markings: Sometimes, the gauge is stamped on the drive link itself.
Drive Link Count
The drive link count is the number of drive links on the chain. This number is specific to the bar length you’re using. A 20-inch bar will require a different drive link count than a 16-inch bar. Using the correct drive link count ensures the chain is the proper length to fit snugly around the bar and sprocket. Too few links, and the chain won’t reach. Too many, and it will be too loose and prone to derailing.
How to Determine the Drive Link Count:
- Check Your Saw’s Manual: This will provide a chart matching bar length to drive link count.
- Count the Links: If you have an old chain, you can manually count the drive links.
- Consult a Dealer: They can quickly determine the correct count based on your bar length.
Personal Experience: I once tried to save a few bucks by using a chain with the wrong drive link count. The chain kept derailing, and I wasted an entire afternoon trying to make it work. Lesson learned: always use the correct specifications!
Pro Tip 2: Matching Chain Type to Cutting Task
Not all chains are created equal. Different chain types are designed for specific cutting tasks. Using the right chain type can significantly improve your cutting efficiency and reduce wear and tear on your saw. Here are a few common types:
Full Chisel Chains
These chains have square-cornered cutters and are known for their aggressive cutting speed. They are ideal for felling clean wood and are preferred by experienced users. However, they dull quickly if they come into contact with dirt or debris.
Semi-Chisel Chains
These chains have rounded-corner cutters, making them more durable and forgiving than full chisel chains. They are a good all-around choice for cutting a variety of wood types, including dirty or knotty wood. They are also easier to sharpen than full chisel chains.
Low-Profile Chains
These chains have a smaller cutter profile, which reduces the risk of kickback. They are a good choice for beginners or anyone concerned about safety. However, they cut slower than full or semi-chisel chains.
Ripping Chains
These chains are specifically designed for cutting wood parallel to the grain, such as when milling lumber. They have a different cutter angle than cross-cutting chains and produce a smoother cut.
Data Point: A study by Oregon Products found that using a full chisel chain can increase cutting speed by up to 20% compared to a semi-chisel chain when cutting clean wood. However, the semi-chisel chain lasted twice as long when cutting dirty wood.
Choosing the Right Chain:
- For felling clean wood: Full chisel chain
- For general-purpose cutting: Semi-chisel chain
- For safety: Low-profile chain
- For milling: Ripping chain
Personal Experience: I once used a ripping chain to cut firewood. It worked, but it was incredibly slow and inefficient. I quickly switched back to a semi-chisel chain and finished the job in half the time.
Pro Tip 3: Bar Length Considerations
The bar length you choose will directly impact the chain size you need. The Husqvarna 450 X-Torq can accommodate bar lengths ranging from 13 inches to 20 inches. Selecting the right bar length depends on the size of the trees you’ll be cutting and your personal preference.
Shorter Bars (13-16 inches)
- Pros: Lighter, more maneuverable, easier to control.
- Cons: Limited cutting capacity, not suitable for large trees.
- Ideal for: Pruning, limbing, cutting small firewood.
Longer Bars (18-20 inches)
- Pros: Greater cutting capacity, can fell larger trees.
- Cons: Heavier, less maneuverable, requires more experience.
- Ideal for: Felling medium-sized trees, cutting large firewood.
Matching Bar Length to Chain:
The longer the bar, the more drive links your chain will need. Consult your saw’s manual or a dealer to determine the correct drive link count for your chosen bar length.
Case Study: A local arborist I know uses a 16-inch bar on his Husqvarna 450 X-Torq for most of his pruning and limbing work. He finds it to be the perfect balance of power and maneuverability. However, when he needs to fell larger trees, he switches to an 18-inch bar.
Personal Experience: I started with a 16-inch bar on my Husqvarna 450 X-Torq. As I gained experience and started felling larger trees, I upgraded to an 18-inch bar. The extra reach made a significant difference.
Pro Tip 4: Chain Maintenance: Sharpening and Lubrication
Even the best chain will perform poorly if it’s not properly maintained. Regular sharpening and lubrication are essential for keeping your chain cutting efficiently and extending its lifespan.
Sharpening
A dull chain is not only inefficient but also dangerous. It requires more force to cut, increasing the risk of kickback. Sharpen your chain regularly, ideally after every few hours of use.
Tools for Sharpening:
- Round File and Guide: This is the most common method for sharpening chainsaw chains. Use a file that matches the pitch of your chain.
- Electric Chain Sharpener: This is a faster and more precise method for sharpening chains.
- Bar-Mounted Sharpener: This is a convenient option for sharpening chains in the field.
Sharpening Technique:
- Secure the Chain: Use a vise or a bar-mounted sharpener to hold the chain securely.
- Maintain the Correct Angle: Use a file guide to maintain the correct angle for the cutters.
- Sharpen Each Cutter Evenly: Make sure to sharpen each cutter to the same length and angle.
Data Point: A sharp chain can reduce cutting time by up to 50% compared to a dull chain. It also reduces the amount of force required to cut, which can help prevent fatigue and injury.
Lubrication
Chainsaw chains require constant lubrication to reduce friction and prevent overheating. Use a high-quality bar and chain oil specifically designed for chainsaws.
Lubrication Technique:
- Check the Oil Level: Check the oil level frequently and refill as needed.
- Adjust the Oil Flow: Adjust the oil flow to match the cutting conditions. More oil is needed for cutting hardwoods or in hot weather.
- Clean the Oil Ports: Keep the oil ports on the bar and saw clean to ensure proper lubrication.
Personal Experience: I once neglected to lubricate my chain properly, and it overheated and broke. It was a costly mistake that could have been avoided with a little bit of maintenance.

- Never Cut Alone: Always have someone nearby in case of an emergency.
Understanding Kickback
Kickback is a sudden, uncontrolled movement of the chainsaw bar that can cause serious injury. It occurs when the tip of the bar comes into contact with an object, or when the chain is pinched in the cut.
Preventing Kickback:
- Use a Low-Kickback Chain: Low-kickback chains have a smaller cutter profile and are less likely to kick back.
- Maintain a Sharp Chain: A sharp chain is less likely to pinch in the cut.
- Use Proper Cutting Techniques: Avoid cutting with the tip of the bar.
- Be Aware of Your Surroundings: Be aware of objects that could cause kickback.
Statistics: According to the Consumer Product Safety Commission, chainsaws cause over 30,000 injuries each year in the United States. Many of these injuries are caused by kickback.
Personal Experience: I once experienced a kickback while cutting firewood. Luckily, I was wearing all of my PPE and was able to avoid serious injury. It was a scary experience that reinforced the importance of safety.
