Chainsaw 550 XP: Ultimate Wood Processing Guide (5 Pro Tips)

As someone deeply involved in wood processing for over two decades, I’ve witnessed firsthand the evolution of tools and techniques. From felling towering trees in the Pacific Northwest forests to meticulously preparing firewood for harsh winters in Scandinavia, the core principles remain the same: safety, efficiency, and respect for the resource. In this guide, I will share my insights on how to maximize the potential of the Husqvarna 550 XP chainsaw for various wood processing tasks, while emphasizing sustainable practices that ensure forests thrive for generations to come.

Sustainability is not just a buzzword; it’s a fundamental principle that should guide every step of wood processing. It means harvesting responsibly, minimizing waste, and ensuring the long-term health of our forests. It’s about understanding the ecological impact of our actions and making choices that benefit both present and future generations. Using the right tools, like the Husqvarna 550 XP, efficiently contributes to this by minimizing fuel consumption and maximizing wood yield.

Understanding Key Concepts

Before we dive into the pro tips, let’s clarify some key terms:

Green Wood vs. Seasoned Wood: Green wood is freshly cut wood with a high moisture content (often above 30%). It’s heavier, harder to split, and prone to warping and cracking as it dries. Seasoned wood, on the other hand, has been air-dried for several months or even years, reducing its moisture content to around 20% or less. Seasoned wood burns more efficiently and is less likely to produce creosote buildup in chimneys.
Bucking: Cutting a felled tree into manageable lengths, typically for firewood, lumber, or transportation.
Felling: The act of cutting down a tree.
Limbing: Removing branches from a felled tree.
Kerf: The width of the cut made by a saw blade or chain.
Bar Oil: A specialized oil used to lubricate the chainsaw bar and chain, reducing friction and wear.
Two-Stroke Engine: An internal combustion engine that completes a power cycle with two strokes of the piston. Chainsaws typically use two-stroke engines, requiring a mixture of gasoline and oil.
Chaps: Protective leg coverings worn by chainsaw operators to prevent injury in case of accidental contact with the chain.
Personal Protective Equipment (PPE): Gear worn to protect against hazards, including a helmet, eye protection, hearing protection, gloves, and chainsaw chaps.

Pro Tip #1: Mastering Safe and Efficient Felling Techniques with the 550 XP

Felling is arguably the most dangerous aspect of wood processing, and it’s crucial to approach it with meticulous planning and the right technique. The Husqvarna 550 XP, with its power and maneuverability, is well-suited for felling trees of moderate size (up to around 20 inches in diameter, depending on the wood type). However, power alone isn’t enough; technique is paramount.

Step-by-Step Guide to Felling:

Risk Assessment: Before even starting the saw, conduct a thorough risk assessment. Look for:
- Lean of the Tree: Which direction is the tree naturally leaning? This will influence its fall.
- Wind Conditions: Wind can drastically alter the tree’s trajectory. Never fell trees in high winds.
- Obstacles: Power lines, buildings, roads, and other trees can pose significant hazards.
- Escape Routes: Plan two clear escape routes at a 45-degree angle away from the anticipated fall direction.
- Dead or Broken Limbs (Widow Makers): These can fall unexpectedly.
Clear the Area: Remove any brush, debris, or obstructions around the base of the tree.
The Notch (or Face Cut): This controls the direction of the fall.
- Conventional Notch: Cut a notch on the side of the tree facing the desired fall direction. The notch should be about 1/3 of the tree’s diameter. The top cut of the notch should be at a 45-degree angle, meeting the horizontal cut.
- Open Face Notch: Similar to the conventional notch but with a wider angle, allowing for a wider range of fall directions. I often use this technique when dealing with trees that have a slight lean in an undesirable direction.
- Humboldt Notch: Less common but useful for very large trees. The top cut is horizontal, and the bottom cut is angled upwards.
The Back Cut: This severs the remaining wood fibers, allowing the tree to fall.
- The back cut should be made slightly above the bottom of the notch, leaving a hinge of uncut wood.
- Hinge Wood: This is crucial for controlling the fall. It acts as a rudder, guiding the tree in the desired direction. The hinge should be uniform in thickness and about 80% of the tree’s diameter.
Felling Lever or Wedges: For larger trees or trees with a strong lean, use a felling lever or wedges to help push the tree over. Insert the wedge into the back cut and use a hammer or another wedge to drive it in.
The Fall: As the tree begins to fall, shout a warning (“Timber!”) and retreat quickly along your pre-planned escape routes.
Limbing and Bucking: Once the tree is on the ground, carefully limb it, working from the base towards the top. Then, buck the tree into desired lengths.

Husqvarna 550 XP Specific Considerations:

Chain Sharpness: A sharp chain is essential for safe and efficient felling. Sharpen your chain regularly, ideally after every tank of fuel. I personally use a Husqvarna file kit with the correct file size for my chain.
Bar Length: The 550 XP can accommodate bars of various lengths. Choose a bar length that is appropriate for the size of the trees you are felling. A 16-inch or 18-inch bar is generally sufficient for most tasks.
RPM Control: The 550 XP’s AutoTune feature automatically adjusts the engine’s settings for optimal performance. However, it’s still important to control the RPMs manually. Use high RPMs for felling and limbing, but reduce the RPMs when idling or moving between cuts.

Personal Experience:

I once had to fell a large oak tree that was leaning precariously towards a neighbor’s house. The wind was also gusting unpredictably, making the situation even more challenging. I spent nearly an hour assessing the risks, planning my cuts, and setting up my escape routes. I used a combination of a conventional notch, a felling lever, and extreme caution to bring the tree down safely and precisely. This experience reinforced the importance of meticulous planning and respecting the power of nature.

Case Study:

Relevant Statistics:

According to the Occupational Safety and Health Administration (OSHA), tree felling is one of the most dangerous occupations in the United States. The fatality rate for logging workers is significantly higher than the national average for all industries. Proper training and adherence to safety protocols are crucial for reducing the risk of accidents.

Pro Tip #2: Optimizing Limbing and Bucking for Maximum Wood Yield

Once the tree is on the ground, the next step is to limb it and buck it into manageable lengths. This is where the Husqvarna 550 XP truly shines, offering a balance of power, maneuverability, and fuel efficiency. The goal here is to maximize wood yield while minimizing waste and physical strain.

Step-by-Step Guide to Limbing and Bucking:

Limbing:
- Work from the Base to the Top: This allows you to work in a safe and controlled manner.
- Use Proper Body Positioning: Avoid overreaching or twisting your body. Position yourself so that you can make clean, controlled cuts.
- Be Aware of Spring Poles: These are branches that are bent under tension. Cut them carefully to avoid being struck by the released energy. I typically make several small cuts on the tension side before completely severing the branch.
- Maintain Chain Sharpness: A dull chain will make limbing more difficult and increase the risk of kickback.
Bucking:
- Plan Your Cuts: Before making any cuts, assess the log for knots, cracks, or other defects. Plan your cuts to minimize waste and maximize the value of the wood.
- Support the Log: Ensure that the log is properly supported to prevent pinching the saw. Use branches or other logs to create a stable base.
- Cutting Techniques:
  - Overbucking: Cutting from the top down. Use this technique when the log is supported on both ends.
  - Underbucking: Cutting from the bottom up. Use this technique when the log is supported in the middle.
  - Boring Cut: Using the tip of the bar to make a plunge cut. This technique is useful for relieving tension in the log before making the final cut. Use extreme caution when performing a boring cut, as it increases the risk of kickback.
- Consistent Lengths: If you are preparing firewood, cut the logs into consistent lengths to make stacking and burning easier. I typically cut my firewood to 16-inch lengths, but this will vary depending on the size of your stove or fireplace.

Husqvarna 550 XP Specific Considerations:

Lightweight Design: The 550 XP’s lightweight design makes it easier to maneuver when limbing and bucking.
X-Torq Engine: The X-Torq engine provides excellent fuel efficiency, allowing you to work longer without refueling.

Pro Tip #5: Mastering Safe Firewood Stacking and Drying Techniques

Proper firewood stacking and drying are essential for producing high-quality firewood that burns efficiently and cleanly. Improper stacking can lead to rot, decay, and insect infestations. Improper drying can result in firewood that is difficult to ignite, produces excessive smoke, and has a low heat output.

Step-by-Step Guide to Firewood Stacking and Drying:

Choose a Location: Select a location that is sunny, well-ventilated, and elevated off the ground. Avoid stacking firewood directly on the ground, as this will promote rot and decay.
Build a Foundation: Create a foundation for your firewood stack using pallets, cinder blocks, or other materials. This will help to keep the firewood dry and prevent it from rotting.
Stack the Firewood: Stack the firewood in a way that allows for good air circulation. There are several different stacking methods you can use, including:
- Traditional Row Stacking: Stacking the firewood in rows, with each row leaning slightly inwards.
- Circular Stacking: Stacking the firewood in a circle, with the pieces leaning inwards towards the center. This method is particularly effective for drying firewood quickly.
- Holz Hausen: A traditional German method of stacking firewood in a circular shape with a central chimney for ventilation. This method is known for its efficiency in drying firewood.
Cover the Firewood: Cover the top of the firewood stack with a tarp or other waterproof material to protect it from rain and snow. Leave the sides of the stack open to allow for air circulation.
Drying Time: Allow the firewood to dry for at least six months, and preferably longer. The drying time will vary depending on the wood species, the climate, and the stacking method.
