The Importance of a Good Chainsaw Case
Before we even touch the bar, let’s talk about the unsung hero of chainsaw ownership: the case. A good chainsaw case isn’t just a convenient way to carry your saw; it’s an investment in its longevity and, more importantly, your safety.
I remember one time, early in my wood-cutting days, I got a little too complacent. I figured a simple cardboard box was enough to transport my saw. Big mistake. The chain oil leaked everywhere, the saw bounced around in the back of my truck, and when I finally got to the site, the chain was dull from rubbing against the box. Not only did I waste time cleaning up the mess, but I also had to spend extra time sharpening the chain before I could even start working.
That day taught me a valuable lesson: a proper chainsaw case is essential. It protects your saw from the elements, prevents accidental damage during transport, and keeps everything organized. Plus, it keeps those sharp teeth safely contained, preventing nasty accidents.
A Husqvarna chainsaw case, specifically designed for a 20-inch bar, is a great choice. These cases are typically made from durable, high-impact plastic that can withstand the rigors of the job site. They also feature custom-molded interiors to keep your saw secure and prevent it from shifting around during transport. Look for cases with integrated storage compartments for tools, extra chains, and other accessories. It makes life so much easier when everything has its place.
Pro Tip 1: Choosing the Right Chain for Your 20-Inch Bar
Okay, let’s get down to the nitty-gritty: the chain. Choosing the right chain for your 20-inch Husqvarna bar is paramount for optimal performance and safety. There are a few key factors to consider.
- Chain Pitch: This refers to the distance between the rivets on the chain. Common pitches for chainsaws include .325″, 3/8″, and .404″. Your bar will be designed for a specific pitch, so make sure you choose a chain that matches. Using the wrong pitch can damage your saw and be extremely dangerous.
- Chain Gauge: This is the thickness of the drive links that fit into the groove of the bar. Again, your bar will be designed for a specific gauge, typically .050″, .058″, or .063″. Using the wrong gauge will prevent the chain from fitting properly on the bar.
- Chain Type: There are several different types of chainsaw chains available, each designed for specific applications.
- Full Chisel Chains: These chains have square-cornered cutters that provide the fastest and most efficient cutting in clean wood. However, they are more prone to dulling quickly if they come into contact with dirt or debris.
- Semi-Chisel Chains: These chains have rounded cutters that are more durable and less prone to dulling than full chisel chains. They are a good choice for cutting dirty or abrasive wood.
- Low-Profile Chains: These chains have a smaller cutter profile that reduces the risk of kickback. They are a good choice for beginners or for cutting in tight spaces.
- Ripping Chains: These chains are specifically designed for cutting wood along the grain, such as when milling lumber.
My Recommendation: For most general-purpose cutting with a 20-inch Husqvarna bar, I recommend a semi-chisel chain with a .325″ pitch and a .050″ gauge. This combination provides a good balance of cutting speed, durability, and safety.
Data Point: According to a study by the Oregon Cutting Systems division of Blount International, semi-chisel chains can maintain their sharpness up to 20% longer than full chisel chains when cutting in abrasive conditions. This can translate to significant time savings and reduced chain replacement costs over the long run.
Pro Tip 2: Properly Mounting and Tensioning the Chain
Once you’ve chosen the right chain, it’s time to mount it on the bar. This is a critical step that can significantly impact the performance and safety of your saw.
- Clean the Bar: Before mounting the chain, make sure the bar is clean and free of debris. Use a wire brush to remove any sawdust, pitch, or dirt from the bar groove.
- Install the Chain: Place the chain over the bar, ensuring that the cutting edges of the teeth are facing in the direction of rotation. The drive links should fit snugly into the bar groove.
- Position the Bar: Place the bar onto the saw, aligning the bar studs with the corresponding holes in the bar.
- Install the Cover: Install the side cover and tighten the nuts finger-tight.
- Tension the Chain: This is where things get a little tricky. The chain tension should be tight enough to prevent it from sagging off the bar, but not so tight that it binds or restricts movement. Here’s how I do it:
- Locate the chain tensioning screw on the side of the saw.
- Use a screwdriver to turn the tensioning screw until the chain is snug against the underside of the bar.
- Lift the chain in the middle of the bar. You should be able to pull the chain out about 1/8″ to 1/4″.
- Tighten the side cover nuts securely.
- Check Tension Again: After tightening the nuts, check the chain tension again. It should still be within the specified range.

Pro Tip 3: Filing and Maintaining Your Chain
A sharp chain is a safe chain. Dull chains require more force to cut, increasing the risk of kickback and operator fatigue. Regular chain filing is essential for maintaining optimal performance and extending the life of your chain.
Tools You’ll Need:
- Chain Filing Kit: This should include a round file, a flat file, a depth gauge tool, and a filing guide.
- Vise: A vise is helpful for holding the chain securely while you’re filing.
The Filing Process:
- Secure the Chain: Place the chain in a vise or use a chain filing tool to hold it securely.
- File the Cutters: Use the round file to sharpen the cutters. Follow the angle and depth guidelines provided by the filing guide. Each cutter should be filed to the same length and angle.
- File the Depth Gauges: Use the flat file and depth gauge tool to adjust the depth gauges. The depth gauges should be slightly lower than the cutters. This helps prevent the chain from grabbing or kicking back.
Frequency: I typically file my chain after every few tanks of fuel, or whenever I notice that it’s becoming dull. It’s better to file frequently and lightly than to wait until the chain is completely dull and requires significant filing.
Unique Insight: One trick I learned from an old logger is to use a permanent marker to mark the first cutter you file. This helps you keep track of which cutters you’ve already sharpened and ensures that you don’t miss any.
Data Point: According to a study by Stihl, a well-maintained chain can cut up to 20% faster than a dull chain. This can translate to significant time savings and increased productivity.
Pro Tip 4: Understanding Bar and Chain Lubrication
Proper lubrication is crucial for extending the life of your bar and chain. Without adequate lubrication, the bar and chain will overheat, causing premature wear and potential failure.
Types of Chain Oil:
- Petroleum-Based Chain Oil: This is the most common type of chain oil. It’s readily available and relatively inexpensive. However, it’s not biodegradable and can be harmful to the environment.
- Vegetable-Based Chain Oil: This type of chain oil is biodegradable and environmentally friendly. It’s a good choice for users who are concerned about the environmental impact of their activities.
- Synthetic Chain Oil: This type of chain oil offers superior performance and protection compared to petroleum-based and vegetable-based oils. It’s more expensive, but it can be worth the investment for users who demand the best possible performance.
My Recommendation: I personally prefer to use a high-quality vegetable-based chain oil. It’s environmentally friendly and provides excellent lubrication.
Lubrication System:
Most chainsaws have an automatic oiler that dispenses oil onto the bar and chain. It’s important to ensure that the oiler is functioning properly and that the oil reservoir is always full.
Checking the Oiler:
- Start the saw and hold it over a clean surface.
- Observe the bar and chain. You should see a steady stream of oil being dispensed onto the chain.
- If you don’t see any oil, check the oil reservoir and make sure it’s full.
- If the reservoir is full and the oiler is still not working, you may need to clean or repair the oiler.
Unique Insight: A little trick I use is to slightly over-oil the chain, especially when cutting hardwoods. This helps to keep the bar and chain cool and prevents premature wear.
Data Point: According to a study by Husqvarna, proper lubrication can extend the life of your bar and chain by up to 50%.
Pro Tip 5: Safe Cutting Techniques and Practices
No matter how well you maintain your chainsaw, it’s only as safe as the person using it. Safe cutting techniques and practices are essential for preventing accidents and injuries.
Personal Protective Equipment (PPE):
- Helmet: Protects your head from falling debris.
- Eye Protection: Protects your eyes from sawdust and flying debris.
- Hearing Protection: Protects your ears from the loud noise of the chainsaw.
- Gloves: Protect your hands from cuts and abrasions.
- Chainsaw Chaps: Protect your legs from chainsaw cuts.
- Steel-Toed Boots: Protect your feet from falling logs and chainsaw cuts.
Cutting Techniques:
- Proper Stance: Stand with your feet shoulder-width apart and your weight evenly distributed. Keep your back straight and your knees slightly bent.
- Grip: Grip the chainsaw firmly with both hands. Keep your thumbs wrapped around the handles.
- Cutting Position: Position yourself so that you are cutting to the side of your body, not directly in front of you.
- Kickback Awareness: Be aware of the risk of kickback, which can occur when the tip of the bar comes into contact with an object. Avoid cutting with the tip of the bar.
- Clearance: Make sure you have a clear escape path in case of an emergency.
Safe Practices:
- Never cut above shoulder height.
- Never cut with one hand.
- Never cut in wet or slippery conditions.
- Never cut under the influence of drugs or alcohol.
- Always inspect the area before cutting to identify any potential hazards.
- Always be aware of your surroundings.
Real Example: I once witnessed a near-fatal accident when a fellow woodcutter violated several of these safety rules. He was cutting above shoulder height, with one hand, in wet conditions. The chainsaw kicked back, and he lost control of it. The chain came dangerously close to his face, and he was lucky to escape with only minor injuries. This incident served as a stark reminder of the importance of following safe cutting techniques and practices.
Data Point: According to the U.S. Consumer Product Safety Commission, there are approximately 30,000 chainsaw-related injuries each year in the United States. Most of these injuries are preventable with proper training and safety precautions.
Beyond the Basics: Wood Species and Their Impact on Chain Wear
Now, let’s delve a bit deeper into the world of wood processing. The type of wood you’re cutting has a significant impact on chain wear and overall cutting efficiency.
Hardwoods vs. Softwoods:
- Hardwoods: These woods are denser and more difficult to cut than softwoods. They tend to dull chains more quickly and require more power to cut. Examples include oak, maple, hickory, and ash.
- Softwoods: These woods are less dense and easier to cut than hardwoods. They are less likely to dull chains and require less power to cut. Examples include pine, fir, spruce, and cedar.
Wood Grain:
The direction of the wood grain also affects cutting efficiency. Cutting with the grain is easier than cutting against the grain. When milling lumber, it’s important to use a ripping chain that is specifically designed for cutting along the grain.
Moisture Content:
The moisture content of the wood can also affect cutting efficiency. Wet wood is more difficult to cut than dry wood. It’s also more likely to clog the chain and bar with sawdust.
Specific Wood Species Considerations:
- Oak: Oak is a very hard and abrasive wood that can quickly dull chains. It’s important to use a durable chain and to file it frequently.
- Maple: Maple is another hard wood that can be challenging to cut. It’s important to use a sharp chain and to maintain proper chain tension.
- Pine: Pine is a relatively soft wood that is easy to cut. However, it can be resinous, which can clog the chain and bar.
- Cedar: Cedar is a soft wood that is easy to cut. It’s also naturally rot-resistant, making it a good choice for outdoor projects.
Case Study: I once worked on a project where I had to mill a large quantity of oak lumber. I quickly learned that my standard chainsaw chain was not up to the task. It was dulling after only a few cuts. I switched to a more durable chain and started filing it more frequently. This significantly improved my cutting efficiency and reduced the amount of time I spent sharpening.
Data Point: A study by the Forest Products Laboratory found that cutting oak can increase chain wear by up to 50% compared to cutting pine.
Optimizing Your Firewood Preparation Process
So, you’ve got your chainsaw humming, your bar properly set up, and you’re ready to tackle that pile of logs. But the job isn’t done yet. Firewood preparation is an art in itself.
The Importance of Seasoning:
Seasoning is the process of drying firewood to reduce its moisture content. Green wood can have a moisture content of up to 50%, while seasoned wood should have a moisture content of 20% or less. Seasoned wood burns hotter, cleaner, and more efficiently than green wood.
Seasoning Time:
The amount of time it takes to season firewood depends on the type of wood, the climate, and the storage conditions. As a general rule, hardwoods should be seasoned for at least six months, while softwoods can be seasoned in as little as three months.
Storage:
Firewood should be stored in a dry, well-ventilated area. Stack the wood in rows, with gaps between the rows to allow for air circulation. Cover the top of the stack to protect it from rain and snow.
Splitting:
Splitting firewood reduces its size, making it easier to handle and store. It also exposes more surface area to the air, which helps it to dry more quickly.
Tools for Splitting:
- Splitting Axe: A splitting axe is a heavy axe with a wide head that is designed for splitting wood.
- Splitting Maul: A splitting maul is similar to a splitting axe, but it has a heavier head and a longer handle.
- Hydraulic Log Splitter: A hydraulic log splitter is a machine that uses hydraulic pressure to split wood.
My Method: I prefer to use a splitting maul for most of my firewood splitting. It’s a good workout, and it’s more efficient than a splitting axe for larger logs. For particularly tough logs, I use a hydraulic log splitter.
Unique Insight: One trick I learned is to split the wood while it’s still slightly green. Green wood is easier to split than dry wood.
Data Point: According to the U.S. Department of Energy, seasoned firewood can produce up to 25% more heat than green firewood.
Remember, safety is paramount. Always wear your PPE, follow safe cutting techniques, and never take shortcuts. And don’t be afraid to experiment and find what works best for you.
As you stand back and admire your neatly stacked woodpile, you’ll feel a sense of accomplishment that’s hard to match. You’ve transformed raw timber into a source of warmth, comfort, and joy. And that, my friends, is a truly rewarding experience. Now, go forth and conquer those logs! And remember, a good Husqvarna chainsaw case is your saw’s best friend – treat it well!
