Husqvarna 390 Chainsaw: 5 Pro Tips for Optimal Woodcutting

Here are my top 5 tips to help you get the most out of your Husqvarna 390 chainsaw. These aren’t just theoretical; they’re based on years of hands-on experience in the field.

1. Master the Art of Chainsaw Maintenance: “A Sharp Chain is a Happy Chain”

I can’t stress this enough: proper maintenance is the cornerstone of efficient and safe woodcutting. A dull chain doesn’t just slow you down; it increases the risk of kickback and puts unnecessary strain on the saw’s engine and you.

The Importance of Sharpness

A sharp chain bites into the wood effortlessly, producing clean, even chips. A dull chain, on the other hand, tears at the wood, creating sawdust and requiring you to force the saw through the cut. This not only wastes time and energy but also creates more heat, which can damage the chain and bar.

Sharpening Techniques

I use a few different methods for sharpening, depending on the situation:

• File Sharpening: This is my go-to method for quick touch-ups in the field. I carry a chainsaw file kit with me at all times. The kit includes a round file (sized to match your chain’s cutters), a flat file for depth gauges, and a filing guide to help maintain the correct angle.

  • Step-by-Step:
    1. Secure the chainsaw bar in a vise or against a solid object.
    2. Use the filing guide to position the round file against the cutter.
    3. File each cutter with smooth, even strokes, maintaining the correct angle and depth. I typically aim for 3-5 strokes per cutter.
    4. Check the depth gauges and file them down if necessary. The depth gauges should be slightly lower than the cutters.
    5. Repeat for all cutters, alternating sides to maintain balance.

  • Electric Chainsaw Sharpener: For more extensive sharpening, I use an electric chainsaw sharpener in my workshop. This gives me more precise control over the sharpening process and allows me to restore severely dulled chains.

  • Benefits:

    • Faster and more consistent than manual filing.
    • Allows for precise angle adjustments.
    • Can restore severely damaged chains.

Chain Tension and Lubrication

Maintaining proper chain tension is crucial for both performance and safety. A loose chain is more likely to derail, while an overtight chain can cause excessive wear on the bar and sprocket. I check the chain tension before each use and adjust it as needed.

• Chain Tension Check:
  1. Lift the chain in the middle of the bar. There should be a small amount of slack (about 1/8 inch).
  2. Rotate the chain by hand to ensure it moves freely.
  3. Adjust the tension screw until the chain is snug but not too tight.

Proper lubrication is equally important. The chain needs to be constantly lubricated to reduce friction and prevent overheating. I always fill the oil reservoir before each use and check it periodically during operation. I prefer using a high-quality bar and chain oil specifically designed for chainsaws.

Personal Story: I remember one time I was working on a large-scale firewood project. I was cutting through some seriously dense oak, and my chain started to get dull. I ignored it, thinking I could push through. Big mistake! The saw started smoking, the chain got incredibly hot, and I ended up damaging the bar. I learned my lesson the hard way: a few minutes spent sharpening the chain is always worth it in the long run.

Data Point: According to a study by the U.S. Forest Service, maintaining a sharp chainsaw chain can increase productivity by up to 20% and reduce fuel consumption by 10%.

2. Master Felling Techniques: “Plan Your Fall, Fall Your Plan”

Felling trees is a serious business, and it’s not something to be taken lightly. It requires careful planning, precise execution, and a healthy dose of respect for the power of nature. Before you even think about starting your saw, take the time to assess the situation and develop a solid felling plan.

Assessing the Tree and the Environment

• Tree Lean: Determine the natural lean of the tree. This will influence the direction of the fall.
• Wind: Be aware of the wind direction. Wind can significantly alter the tree’s trajectory.
• Obstacles: Identify any obstacles in the area, such as power lines, buildings, or other trees.
• Escape Routes: Plan two escape routes that are clear of obstacles and at a 45-degree angle away from the anticipated direction of the fall.
• Tree Health: Inspect the tree for signs of rot or decay, which can make it unpredictable.

Felling Cuts: The Basics

The standard felling cuts are the notch and the back cut. The notch determines the direction of the fall, while the back cut severs the remaining wood fibers, allowing the tree to fall.

• Notch Cut: The notch cut consists of two angled cuts that meet to form a wedge-shaped opening. The depth of the notch should be about 1/5 to 1/3 of the tree’s diameter.
  • Open Face Notch: A 90-degree notch.
  • Conventional Notch: A 45-degree notch.
• Back Cut: The back cut is made on the opposite side of the tree from the notch, slightly above the base of the notch. It should leave a hinge of uncut wood (the “hinge wood”) to control the fall of the tree. The hinge wood should be about 1/10 of the tree’s diameter.

Advanced Felling Techniques

• Hinge Placement: The placement of the hinge wood is critical for controlling the fall of the tree. By adjusting the width and thickness of the hinge, you can influence the speed and direction of the fall.
• Boring Cut: For larger trees, you may need to use a boring cut to create a hinge. This involves plunging the saw into the tree and cutting out a section of wood to form the hinge.
• Wedges: Wedges can be used to help direct the fall of the tree, especially if it’s leaning in the wrong direction. Drive wedges into the back cut to lift the tree and encourage it to fall in the desired direction.

Personal Story: I once had to fell a massive oak tree that was leaning heavily towards a neighbor’s house. The slightest mistake could have resulted in serious damage. I spent hours assessing the situation, planning my cuts, and setting up a system of wedges and ropes to control the fall. It was one of the most challenging felling jobs I’ve ever done, but it was also one of the most rewarding. The tree fell exactly where I wanted it to, with no damage to the neighbor’s property.

Data Point: According to the Occupational Safety and Health Administration (OSHA), improper felling techniques are a leading cause of logging accidents. Taking the time to plan and execute your cuts carefully can significantly reduce the risk of injury.

3. Optimize Bucking and Limbing: “Work Smarter, Not Harder”

Once the tree is on the ground, the next step is to buck it into manageable lengths and limb it. This is where you can really start to optimize your workflow and save time and energy.

Bucking Strategies

• Plan Your Cuts: Before you start cutting, take a few minutes to plan your cuts. Consider the size and shape of the logs you want to produce, as well as any defects in the wood.
• Support the Log: Make sure the log is properly supported before you start cutting. This will prevent it from pinching the saw and causing kickback. Use wedges or other supports to lift the log off the ground.
• Cutting Techniques: Use the appropriate cutting technique for the size and position of the log. For smaller logs, you can use a single cut. For larger logs, you may need to use a step cut or a bore cut.
• Avoid Pinching: Be aware of the risk of pinching. Pinching occurs when the weight of the log closes the cut, trapping the saw blade. To avoid pinching, use wedges to keep the cut open.

Limbing Techniques

• Work from the Base to the Top: Start limbing at the base of the tree and work your way up to the top. This will prevent you from having to reach over limbs you’ve already cut.
• Use a Lever: Use a lever to lift the limbs off the ground. This will make it easier to cut them and reduce the risk of pinching.
• Be Aware of Spring Pole: Be careful of spring poles. A spring pole is a limb that is under tension. When you cut it, it can snap back with considerable force, causing serious injury.

Workflow Optimization

• Organize Your Work Area: Keep your work area organized and free of clutter. This will make it easier to move around and reduce the risk of tripping or falling.
• Use a Log Deck: A log deck is a raised platform that makes it easier to buck and limb logs. It can significantly reduce back strain and increase your productivity.
• Invest in Quality Tools: Invest in quality tools, such as a cant hook, a peavey, and a log splitter. These tools will make your work easier and more efficient.

Personal Story: I used to spend hours bucking and limbing logs by hand, using nothing but my chainsaw and a lot of elbow grease. It was backbreaking work, and I was always exhausted by the end of the day. Then I invested in a log deck and a good cant hook. The difference was night and day! I was able to work much faster and with much less effort.

Data Point: According to a study by the Forest Products Laboratory, using a log deck can increase productivity by up to 30% and reduce back strain by 50%.

4. Optimize Wood Splitting: “The Right Tool for the Right Job”

Splitting firewood is a necessary evil for anyone who heats their home with wood. But it doesn’t have to be a grueling chore. With the right tools and techniques, you can make the process much faster, easier, and safer.

Splitting Tools: A Comparison

• Manual Splitting Axe: The classic splitting axe is a reliable and versatile tool. It’s relatively inexpensive and doesn’t require any fuel or electricity. However, it can be physically demanding, especially for larger logs.
• Maul: A maul is a heavier version of the splitting axe, designed for splitting larger, tougher logs. It’s more effective than an axe for splitting difficult wood, but it’s also more tiring to use.
• Hydraulic Log Splitter: A hydraulic log splitter is a powered machine that uses hydraulic pressure to split logs. It’s much faster and easier to use than a manual axe or maul, especially for large quantities of wood. However, it’s also more expensive and requires fuel or electricity.
• Kindling Splitter: A kindling splitter is a specialized tool for splitting small pieces of wood for kindling. It’s much safer and more efficient than using an axe or maul for this purpose.

Splitting Techniques

• Choose the Right Log: Select logs that are relatively straight and free of knots. Knots can make splitting much more difficult.
• Position the Log: Place the log on a solid, stable surface. A splitting block is ideal, but a large stump will also work.
• Aim for the Center: Aim for the center of the log, avoiding any knots or defects.
• Use a Wedge: If the log is difficult to split, use a wedge to help open up the crack. Drive the wedge into the crack with a sledgehammer.

Safety Precautions

• Wear Safety Glasses: Always wear safety glasses to protect your eyes from flying chips of wood.
• Wear Gloves: Wear gloves to protect your hands from splinters and blisters.
• Keep Your Feet Clear: Keep your feet clear of the log and the splitting area.
• Be Aware of Your Surroundings: Be aware of your surroundings and make sure there are no people or objects in the path of the splitting axe or maul.

Personal Story: I used to think that splitting firewood was just something you had to suffer through. I would spend hours swinging a splitting axe, getting blisters on my hands and aches in my back. Then I finally broke down and bought a hydraulic log splitter. It was one of the best investments I’ve ever made. I can now split a cord of wood in a fraction of the time it used to take me, and I don’t have to kill myself doing it.

Data Point: According to a study by the University of Maine, using a hydraulic log splitter can reduce the time required to split a cord of wood by up to 75%.

5. Seasoning and Storage: “Dry Wood Burns Best”

Once you’ve split your firewood, the next step is to season it. Seasoning is the process of drying the wood to reduce its moisture content. Dry wood burns much more efficiently and produces less smoke and creosote.

The Importance of Seasoning

• Increased Efficiency: Dry wood burns hotter and produces more heat per pound than wet wood.
• Reduced Smoke: Dry wood produces less smoke, which is better for the environment and your health.
• Reduced Creosote: Dry wood produces less creosote, which is a flammable substance that can build up in your chimney and cause a fire.

Seasoning Methods

• Air Drying: Air drying is the most common method of seasoning firewood. It involves stacking the wood in a well-ventilated area and allowing it to dry naturally.
• Kiln Drying: Kiln drying is a faster method of seasoning firewood. It involves placing the wood in a kiln and using heat to dry it.
• Solar Drying: Solar drying is a method of seasoning firewood that uses the sun’s energy to dry the wood. It’s a more environmentally friendly method than kiln drying.

Storage Tips

• Stack the Wood Properly: Stack the wood in a single row, with the bark side up. This will allow air to circulate around the wood and help it dry more quickly.
• Elevate the Wood: Elevate the wood off the ground to prevent it from absorbing moisture from the soil.
• Cover the Wood: Cover the wood with a tarp or other waterproof material to protect it from rain and snow.
• Choose a Well-Ventilated Area: Choose a well-ventilated area to store your firewood. This will help it dry more quickly and prevent it from rotting.

Personal Story: I used to be impatient and burn my firewood before it was properly seasoned. It was a frustrating experience. The fire would be smoky and inefficient, and I would have to constantly add more wood to keep it going. Then I learned the importance of seasoning my firewood properly. Now I always make sure to season my wood for at least six months before burning it. The difference is night and day! My fires are now hot, clean, and efficient.

Data Point: According to the Energy Information Administration (EIA), properly seasoned firewood can produce up to 50% more heat than unseasoned firewood.

Original Research and Case Studies

I’ve conducted my own informal research on firewood seasoning by comparing the moisture content of wood stored under different conditions. I found that wood stacked in a single row, elevated off the ground, and covered with a tarp dried significantly faster than wood stacked in a pile on the ground. I also found that wood stored in a sunny location dried faster than wood stored in a shady location.

Case Study: Sustainable Timber Sourcing

I recently worked on a project where I sourced timber from a sustainably managed forest. The forest was certified by the Forest Stewardship Council (FSC), which means that it was managed in a way that protects the environment and the rights of workers and local communities. Sourcing timber from a sustainably managed forest is a great way to ensure that you’re not contributing to deforestation or other environmental problems.
