Husqvarna SP33G Chainsaw Chains (5 Must-Know Tips For Longevity)

My grandfather, a man whose hands were as rough as bark and whose heart was as warm as a wood stove, taught me everything I know about working with wood. From felling trees in the crisp autumn air to splitting logs under the summer sun, these were more than chores; they were lessons in patience, respect, and the enduring value of hard work. He always said, “A sharp chain is a safe chain, and a well-cared-for chain is a long-lived chain.” It’s this wisdom, passed down through generations, that I want to share with you today. We’re going to dive deep into the world of Husqvarna SP33G chainsaw chains and uncover five essential tips to maximize their lifespan. But it’s not just about the chain itself; it’s about understanding the costs involved, budgeting wisely, and ensuring that every cut you make is efficient and cost-effective.

Husqvarna SP33G Chainsaw Chains: 5 Must-Know Tips for Longevity

The Husqvarna SP33G chain is a popular choice among both hobbyists and professionals for its durability and cutting performance. However, even the best chains will wear out if not properly maintained. Understanding how to prolong the life of your SP33G chain will not only save you money in the long run but also improve your overall cutting experience. Let’s look at five key tips to achieve this, and how they tie into the broader picture of chainsaw maintenance costs.

1. Proper Sharpening is Paramount

This might seem obvious, but the importance of proper sharpening cannot be overstated. A dull chain is not only less efficient, requiring more force and fuel, but it also puts unnecessary strain on your chainsaw’s engine and bar.

Why Sharpening Matters: A sharp chain cuts cleanly, producing chips rather than sawdust. This reduces friction and heat, which are major contributors to chain wear.
The Right Tools: Investing in a quality chainsaw sharpening kit is crucial. This includes a file guide, round files (typically 5/32″ for the SP33G), a flat file for depth gauges, and a raker gauge. Expect to pay anywhere from $20 to $50 for a decent kit. I prefer the kits with guides as they really help maintain the correct angle.
The Correct Angle: The SP33G chain typically requires a 30-degree sharpening angle. Consult your chainsaw manual or the chain packaging for the exact specifications. Maintaining the correct angle ensures optimal cutting performance and prevents uneven wear on the cutters.
Depth Gauges (Rakers): Don’t forget the depth gauges! These small protrusions in front of each cutter control the amount of wood each cutter takes. As the cutters are sharpened, the depth gauges become relatively higher and need to be filed down. Use a flat file and a raker gauge to ensure they are at the correct height. Failing to adjust the rakers will result in a chain that won’t “bite” into the wood effectively.
Frequency: How often should you sharpen? As a general rule, sharpen your chain every time you refuel. This keeps the chain consistently sharp and prevents it from becoming excessively dull. If you notice the chain is producing sawdust instead of chips, or if you have to apply excessive pressure to make it cut, it’s time to sharpen.
Cost Implications: Ignoring sharpening can lead to premature chain replacement. A new SP33G chain can cost anywhere from $20 to $40, depending on the length. Sharpening regularly, on the other hand, prolongs the chain’s life and reduces the frequency of replacements. Furthermore, a dull chain consumes more fuel. I’ve seen fuel consumption increase by as much as 20% when using a dull chain. Over the course of a year, this can add up to a significant expense.
DIY vs. Professional Sharpening: You can sharpen the chain yourself, which saves money on labor costs. However, if you’re not comfortable sharpening or lack the necessary tools, consider professional sharpening services. These typically cost around $10 to $20 per chain. While it’s an added expense, a professional sharpening ensures the chain is sharpened correctly and can extend its lifespan.

2. Proper Chain Lubrication: The Lifeblood of Your Chain

Lubrication is absolutely critical for reducing friction and wear on the chain and bar. Without proper lubrication, the chain will overheat, stretch, and eventually break.

The Right Oil: Use a high-quality bar and chain oil specifically designed for chainsaws. These oils contain additives that help them cling to the chain and provide superior lubrication. I recommend using a biodegradable oil whenever possible, as it’s better for the environment.
Oil Level Checks: Regularly check the oil level in your chainsaw’s reservoir. Never run the chainsaw with an empty or low oil level. I make it a habit to refill the oil reservoir every time I refuel the gas tank.
Oil Flow Adjustment: Most chainsaws have an adjustable oiler that allows you to control the amount of oil being delivered to the chain. Adjust the oil flow according to the type of wood you’re cutting and the ambient temperature. Harder woods and higher temperatures require more oil.
Signs of Insufficient Lubrication: Watch out for signs of insufficient lubrication, such as smoke coming from the chain, discoloration of the chain or bar, or excessive heat buildup. If you notice any of these signs, stop cutting immediately and check the oil level and oiler settings.
Cleaning the Oiler: Periodically clean the oiler to ensure it’s functioning properly. Debris and sawdust can clog the oiler, restricting oil flow. I use compressed air to clean the oiler after each use.
Cost Implications: Neglecting lubrication can lead to premature wear of the chain, bar, and even the chainsaw’s engine. Replacing a worn-out bar can cost anywhere from $30 to $100, depending on the length and brand. Furthermore, a lack of lubrication can cause the chain to stretch and break, which can be dangerous. The cost of bar and chain oil can vary depending on the brand and quantity, but it’s a relatively small expense compared to the cost of replacing damaged parts. A gallon of high-quality bar and chain oil typically costs around $15 to $30.
Personal Experience: I once made the mistake of using regular motor oil as bar and chain oil. The chain quickly overheated and stretched, and the bar became discolored. I learned my lesson the hard way: always use the right oil for the job.

3. Proper Chain Tension: Finding the Sweet Spot

Maintaining the correct chain tension is essential for safe and efficient cutting. A chain that is too loose can derail from the bar, while a chain that is too tight can overheat and stretch.

Checking Tension: Check the chain tension before each use and periodically during use. The chain should be snug against the underside of the bar but should still be able to be pulled around the bar by hand.
Adjusting Tension: Most chainsaws have a tensioning screw that allows you to adjust the chain tension. Loosen the bar nuts slightly, adjust the tensioning screw until the chain is at the correct tension, and then retighten the bar nuts.
New Chains: New chains tend to stretch more than older chains. Check the tension frequently during the first few hours of use.
Temperature Considerations: Chain tension can change with temperature. The chain will expand when it gets hot and contract when it cools down. Adjust the tension accordingly.
Signs of Incorrect Tension: A chain that is too loose will sag noticeably and may derail from the bar. A chain that is too tight will be difficult to pull around the bar and may produce excessive heat and friction.
Cost Implications: Incorrect chain tension can lead to premature wear of the chain and bar. A loose chain can damage the drive sprocket, while a tight chain can cause the bar to warp. The cost of replacing a drive sprocket can range from $20 to $50, while the cost of replacing a bar can range from $30 to $100. Furthermore, a chain that is too tight can put extra strain on the chainsaw’s engine, potentially leading to more serious and costly repairs.
Tensioning Technique: I always make sure the chain is cool before adjusting the tension. A hot chain will give a false reading, and you might end up overtightening it when it cools down.

4. Choosing the Right Chain for the Job

Using the correct chain for the type of wood you’re cutting is crucial for both performance and longevity. The Husqvarna SP33G is a versatile chain, but it’s not ideal for all situations.

Wood Type: Softwoods like pine and fir are easier to cut than hardwoods like oak and maple. For hardwoods, consider using a chain with a more aggressive cutter design.
Chain Pitch and Gauge: Ensure that the chain pitch and gauge match the specifications of your chainsaw and bar. Using the wrong chain can damage the chainsaw and be dangerous. The SP33G typically comes in a .325″ pitch and .050″ gauge.
Chain Type: Different types of chains are designed for different purposes. Full chisel chains are designed for fast cutting in clean wood, while semi-chisel chains are more durable and better suited for cutting dirty or frozen wood. The SP33G is a semi-chisel chain, offering a good balance of cutting speed and durability.
Sharpening Needs: Consider the sharpening needs of different chain types. Full chisel chains require more frequent sharpening than semi-chisel chains.
Cost Implications: Using the wrong chain can lead to premature wear and reduced cutting efficiency. A chain that is not designed for the type of wood you’re cutting will dull more quickly and require more frequent sharpening. This can increase your overall operating costs. I once tried using a full chisel chain to cut some dirty, knotty firewood. The chain dulled almost immediately, and I ended up wasting a lot of time and effort.
Chain Selection Example: If you’re primarily cutting softwood for firewood, the SP33G is a good choice. However, if you’re cutting a lot of hardwood, you might consider a chain with a more aggressive cutter design, even if it requires more frequent sharpening.

5. Cleaning and Storage: Protecting Your Investment

Proper cleaning and storage are essential for preventing rust and corrosion and prolonging the life of your chainsaw chain.

Cleaning After Use: After each use, clean the chain with a brush and solvent to remove sawdust, sap, and oil. This prevents these materials from hardening and causing corrosion.
Drying: After cleaning, dry the chain thoroughly to prevent rust. I use compressed air to blow out any remaining moisture.
Oiling: Lightly oil the chain with bar and chain oil before storing it. This provides a protective layer against rust and corrosion.
Storage Location: Store the chain in a dry, protected location away from direct sunlight and extreme temperatures. I keep my chains in a toolbox lined with oil-soaked rags.
Long-Term Storage: For long-term storage, consider wrapping the chain in oil-soaked cloth or storing it in a sealed container with a desiccant to absorb moisture.
Cost Implications: Neglecting cleaning and storage can lead to rust and corrosion, which can weaken the chain and reduce its lifespan. A rusted chain is more likely to break and can also damage the bar and drive sprocket. The cost of replacing a rusted chain can range from $20 to $40, while the cost of replacing a damaged bar or drive sprocket can range from $30 to $100. Furthermore, a rusted chain is less efficient and requires more effort to cut, which can increase your overall operating costs.
Rust Prevention: I’ve found that spraying the chain with WD-40 before storing it helps to prevent rust. Just be sure to clean and oil the chain properly before using it again.
