Husqvarna 390 XP Chainsaw (5 Hidden Features Pros Love)

Layering. It’s not just for staying warm in the woods; it’s the secret to success in any wood processing or firewood preparation project. Think about it: you layer your clothing to adapt to changing conditions, and you need to layer your planning, execution, and knowledge to conquer the challenges of transforming raw timber into something useful – be it lumber, firewood, or a beautiful piece of woodworking.

I’ve spent the better part of my life immersed in the world of wood. From felling trees in the crisp morning air to splitting logs under the blazing summer sun, I’ve learned that a strategic approach is just as crucial as a sharp chainsaw. And speaking of chainsaws, the Husqvarna 390 XP holds a special place in my heart. It’s a workhorse, no doubt, but it’s more than just raw power. It’s about understanding its nuances, its hidden features, and how it fits into a larger, well-orchestrated plan.

Unleashing the Potential: Project Success with the Husqvarna 390 XP

Before we even touch the chainsaw, let’s talk about the big picture. Any successful wood processing project, whether it’s clearing land, milling lumber, or simply stocking up for winter, hinges on careful planning and execution. Think of it as building a house – you wouldn’t start hammering nails without a blueprint, would you?

Planning Your Assault: Defining Project Scope and Objectives

The first step is defining the scope of your project. What are you trying to achieve? Are you clearing a small area for a garden? Felling trees for a cabin build? Or producing cords of firewood for sale?

Clarity is key: Write down your objectives. Be specific. “Cut firewood for the winter” is vague. “Produce 4 cords of seasoned oak firewood” is much better.
Assess your resources: What equipment do you have? What manpower is available? What’s your budget?
Consider the timeline: When do you need to complete the project? Factor in time for felling, bucking, splitting, stacking, and seasoning.

I remember one project where I severely underestimated the drying time for a large batch of oak. I ended up with a mountain of firewood that was still too green to burn efficiently come winter. Lesson learned: always overestimate drying time! According to the Forest Products Laboratory, hardwoods like oak can take anywhere from 6 to 12 months to properly season, sometimes longer depending on the climate.

Selecting Your Weapon: Why the Husqvarna 390 XP?

Okay, now we can talk about the chainsaw. The Husqvarna 390 XP isn’t just any chainsaw; it’s a powerhouse designed for demanding tasks. It’s got the guts to handle large trees and long days. But why this saw specifically?

Power-to-weight ratio: The 390 XP offers a fantastic balance of power and weight, making it manageable for extended use. This is crucial for reducing fatigue and preventing accidents.
Durability: These saws are built to last. With proper maintenance, a 390 XP can provide years of reliable service.

Unveiling the 5 Hidden Features Pros Love (and You Will Too)

These features are not “hidden” in the sense they are secret, but more that they are not always immediately apparent or fully appreciated by new users.

1. The Inertia-Activated Chain Brake: A Lifesaver in Disguise

This isn’t exactly “hidden,” but its importance is often overlooked. The inertia-activated chain brake is a critical safety feature that can prevent serious injuries in the event of kickback.

How it works: The brake is designed to engage automatically if the saw experiences a sudden upward or backward movement.
Why it’s important: Kickback is one of the most common causes of chainsaw accidents. The chain brake can stop the chain almost instantly, reducing the severity of the impact.
Pro Tip: Always check the chain brake before starting the saw. Make sure it engages smoothly and disengages completely.

I’ve had a few close calls over the years, and I can tell you firsthand that a properly functioning chain brake is worth its weight in gold. It’s not just a feature; it’s a peace of mind.

2. The Centrifugal Air Cleaning System: Engine Longevity

The 390 XP features Husqvarna’s centrifugal air cleaning system, which pre-cleans the intake air before it reaches the air filter. This drastically reduces the amount of dust and debris that enters the engine, extending the life of both the air filter and the engine itself.

How it works: The system uses centrifugal force to separate heavier particles from the intake air.
Why it’s important: A clean air filter allows the engine to run more efficiently and prevents premature wear.
Pro Tip: Even with the centrifugal air cleaning system, you still need to clean the air filter regularly. I recommend cleaning it after every few tanks of fuel.

This feature is especially valuable in dusty environments. I once worked on a land clearing project in the middle of summer, and without the centrifugal air cleaning system, I would have been constantly cleaning or replacing the air filter.

3. The Adjustable Oil Pump: Tailoring Lubrication to the Task

The 390 XP has an adjustable oil pump, allowing you to control the amount of oil delivered to the bar and chain. This is crucial for optimizing lubrication and preventing premature wear.

How it works: A small screw on the bottom of the saw allows you to adjust the oil flow.
Why it’s important: Too little oil can lead to overheating and damage to the bar and chain. Too much oil is wasteful and can create a mess.
Pro Tip: Adjust the oil flow based on the type of wood you’re cutting and the length of the bar. Hardwoods require more oil than softwoods.

I’ve seen firsthand the damage that can result from inadequate lubrication. A friend of mine burned out a perfectly good bar and chain because he neglected to adjust the oil pump when switching from softwood to hardwood.

4. The Magnesium Crankcase: Strength Without the Weight

The 390 XP’s crankcase is made from magnesium, which provides excellent strength and durability while keeping the weight down.

How it works: Magnesium is a lightweight metal with a high strength-to-weight ratio.
Why it’s important: A strong crankcase is essential for withstanding the stresses of demanding use. The lightweight design reduces fatigue and improves maneuverability.
Pro Tip: While magnesium is strong, it’s also susceptible to corrosion. Keep the crankcase clean and dry to prevent damage.

The magnesium crankcase is one of the reasons why the 390 XP feels so well-balanced in your hands. It’s a testament to Husqvarna’s commitment to quality and performance.

5. The Smart Start Decompression Valve: Easy Starts Every Time

The 390 XP features a decompression valve, also known as Smart Start, which reduces the compression in the cylinder, making it easier to pull the starter cord.

How it works: The decompression valve releases some of the pressure in the cylinder, reducing the force required to turn the engine over.
Why it’s important: Makes starting the saw easier, especially in cold weather.
Pro Tip: Always use the decompression valve when starting the saw, especially when the engine is cold.

I’ve used chainsaws that were a real bear to start, especially on cold mornings. The Smart Start feature on the 390 XP is a game-changer. It saves you time, energy, and frustration.

From Forest to Firewood: Optimizing Your Workflow

Now that we’ve explored the features of the Husqvarna 390 XP, let’s talk about optimizing your workflow for maximum efficiency. Whether you’re processing lumber or preparing firewood, a well-organized workflow can save you time, energy, and money.

Felling Techniques: Precision and Safety First

Felling is the most dangerous part of any wood processing project. It’s crucial to use proper techniques and prioritize safety above all else.

Assess the tree: Look for signs of weakness, such as dead branches, cracks in the trunk, or leaning.
Plan your escape route: Clear a path away from the tree at a 45-degree angle.
Make the notch: The notch determines the direction of the fall. It should be about one-fifth of the tree’s diameter.
Make the back cut: The back cut should be slightly higher than the notch and should leave a hinge of wood to control the fall.
Use wedges: Wedges can help to prevent the tree from pinching the saw and to steer the fall.

I once saw a logger who neglected to properly assess a tree before felling it. The tree had a hidden lean, and it fell in the wrong direction, narrowly missing him. It was a stark reminder of the importance of taking the time to do things right.

Bucking and Splitting: Efficiency and Ergonomics

Once the tree is on the ground, it’s time to buck it into manageable lengths and split it for drying.

Bucking: Use a sawhorse to support the log and make accurate cuts. Consider the intended use of the wood when determining the length of the cuts.
Splitting: Use a splitting axe or a hydraulic log splitter. Choose a splitting tool that is appropriate for the size and type of wood you’re splitting.
Ergonomics: Pay attention to your posture and movements to avoid strain and injury. Take breaks as needed.

I’ve found that using a hydraulic log splitter can dramatically increase my productivity when splitting firewood. It’s an investment that pays for itself in time and energy savings. 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 50%.

Stacking and Seasoning: The Art of Drying

Proper stacking and seasoning are essential for producing high-quality firewood.

Stacking: Stack the wood in a way that allows for good air circulation. Leave gaps between the rows and stacks.
Location: Choose a sunny, well-ventilated location for your woodpile.
Covering: Cover the top of the woodpile to protect it from rain and snow.
Seasoning Time: Allow the wood to season for at least six months, preferably longer.

I’ve learned that the key to successful seasoning is patience. Don’t rush the process. Properly seasoned firewood burns hotter, cleaner, and more efficiently. I aim for moisture content below 20% before burning. A good moisture meter is an invaluable tool.

Sustainable Wood Processing: Respecting the Resource

As stewards of the land, it’s our responsibility to practice sustainable wood processing techniques. This means harvesting trees responsibly, minimizing waste, and protecting the environment.

Responsible Harvesting: Selective Cutting and Reforestation

Selective cutting: Choose trees to harvest based on their maturity, health, and location. Avoid clear-cutting large areas.
Reforestation: Plant new trees to replace those that have been harvested.
Protecting waterways: Avoid cutting trees near streams or rivers to prevent erosion and protect water quality.

I’ve seen the devastating effects of unsustainable logging practices firsthand. It’s crucial to prioritize the long-term health of the forest over short-term profits.

Minimizing Waste: Using All Parts of the Tree

Firewood: Use smaller branches and scraps for firewood.
Mulch: Chip larger branches and use them for mulch.
Sawdust: Use sawdust for composting or as animal bedding.

I try to use every part of the tree whenever possible. It’s a way of honoring the resource and reducing my environmental impact.

Tool Maintenance and Safety: A Non-Negotiable

The Husqvarna 390 XP is a powerful tool, but it’s only as good as the person using it. Proper maintenance and safety are essential for preventing accidents and ensuring the long life of your equipment.

Chainsaw Maintenance: Keeping Your Saw in Top Condition

Sharpen the chain: A sharp chain is essential for efficient cutting and safety. Sharpen the chain regularly using a file or a chain grinder.
Clean the air filter: Clean the air filter after every few tanks of fuel.
Check the bar and chain: Inspect the bar and chain for wear and damage. Replace them as needed.
Lubricate the bar and chain: Use a high-quality bar and chain oil.
Drain the fuel: Drain the fuel from the tank if you’re not going to be using the saw for an extended period.

I make it a habit to sharpen my chainsaw chain every time I refuel. It only takes a few minutes, and it makes a huge difference in performance.

Safety Gear: Protecting Yourself from Injury

Helmet: Wear a helmet with a face shield to protect your head and face from falling debris.
Eye protection: Wear safety glasses or goggles to protect your eyes from flying chips.
Hearing protection: Wear earplugs or earmuffs to protect your hearing from the noise of the chainsaw.
