FS90 Stihl Trimmer Insights (5 Pro Tips for Wood Processing)

Let’s dive in.

Introduction: Weathering the Elements – Why Waterproofing Matters in Wood Processing

Before we even begin to discuss the pro tips for wood processing using the FS90 Stihl Trimmer, let’s talk about something crucial: the weather. That’s why understanding waterproofing options is so important. Think about it – your tools are exposed to rain, snow, and humidity, and your processed wood is vulnerable to rot and decay. Ignoring this aspect can lead to premature tool failure, wasted materials, and a lot of frustration.

I once left a brand new chainsaw sitting out in the rain overnight. The next day, the chain was already showing signs of rust, and the engine was noticeably harder to start. That was a costly lesson that drove home the importance of protecting my equipment. Similarly, I’ve seen stacks of firewood rendered useless by unchecked moisture, turning what was supposed to be a source of warmth into a pile of moldy waste.

So, what are your options for waterproofing? For your tools, consider investing in waterproof storage containers or sheds. Regularly applying a moisture-displacing lubricant can also help prevent rust and corrosion. Tarps are a good option, but make sure they’re breathable to allow for air circulation. You can also use natural waterproofing methods like applying linseed oil or beeswax to the wood surface.

Waterproofing isn’t just about protecting your investment; it’s about safety. Damp wood is harder to cut and split, increasing the risk of accidents. Rusted tools are more likely to fail, potentially causing serious injuries. By taking the time to waterproof your equipment and materials, you’re creating a safer and more efficient work environment. Now that we’ve covered the importance of waterproofing, let’s move on to the pro tips for wood processing using the FS90 Stihl Trimmer.

Wood Anatomy and Properties: Understanding Your Material

Before diving deeper into wood processing techniques, it’s crucial to understand the material itself: wood. Wood isn’t just a homogenous substance; it’s a complex, organic material with varying properties that affect how it behaves during processing, drying, and burning.

• Hardwood vs. Softwood: The terms “hardwood” and “softwood” don’t necessarily refer to the actual hardness of the wood. Hardwoods come from deciduous trees (trees that lose their leaves annually), while softwoods come from coniferous trees (trees that typically have needles and cones). Generally, hardwoods are denser and more durable than softwoods, making them suitable for furniture, flooring, and other high-wear applications. Softwoods, on the other hand, are often used for construction, paper production, and firewood.

  • Example: Oak is a hardwood known for its strength and durability, while pine is a softwood that is easy to work with and readily available.
  • Grain Structure: The grain of wood refers to the arrangement of its fibers. Straight-grained wood is easy to split and work with, while wood with knots or irregular grain can be more challenging.

  • Moisture Content: Moisture content is the amount of water present in wood, expressed as a percentage of the wood’s dry weight. Freshly cut wood can have a moisture content of over 100%, while properly seasoned firewood should have a moisture content of 20% or less.

  • Data Point: The ideal moisture content for firewood is between 15% and 20%. Wood with a moisture content above 20% will be difficult to light and will produce more smoke and less heat.

  • Density: Density is the mass per unit volume of wood. Denser woods generally burn longer and produce more heat than less dense woods.

  • Example: Osage orange is one of the densest woods in North America, making it an excellent choice for firewood.

  • Cell Structure: Wood is primarily composed of cellulose, hemicellulose, and lignin. The arrangement of these components creates the cell structure of the wood, which influences its strength, flexibility, and resistance to decay.

Logging Tool Selection and Maintenance Best Practices

Choosing the right logging tools is essential for safety, efficiency, and the quality of your wood processing projects. But merely owning the tools isn’t enough; proper maintenance is equally important to ensure they function correctly and last for years.

• Chainsaws: Chainsaws are indispensable for felling trees, limbing branches, and bucking logs. When selecting a chainsaw, consider the size of the trees you’ll be cutting, the frequency of use, and your budget.

  • Comparison: Electric chainsaws are quieter and require less maintenance than gas-powered chainsaws, but they are typically less powerful and have a limited runtime. Gas-powered chainsaws are more powerful and portable, but they require more maintenance and produce emissions.
  • Axes and Splitting Mauls: Axes are used for felling small trees and limbing branches, while splitting mauls are designed for splitting logs. Choose an axe or maul with a weight and handle length that is comfortable for you to use.
  • Wedges: Wedges are used to prevent a tree from pinching the chainsaw bar during felling and to split stubborn logs. Steel wedges are more durable than plastic wedges, but they can damage a chainsaw chain if struck accidentally.
  • Cant Hooks and Log Lifters: Cant hooks are used to roll logs, while log lifters are used to lift logs. These tools can help you move heavy logs safely and efficiently.

  • Personal Protective Equipment (PPE): PPE is essential for protecting yourself from injury while logging. This includes a helmet, eye protection, hearing protection, gloves, chainsaw chaps, and steel-toed boots.

  • Statistics: According to the CDC, approximately 30,000 people are treated in emergency rooms each year for chainsaw-related injuries. Wearing appropriate PPE can significantly reduce the risk of injury.

Maintenance Best Practices:

• Chainsaw Chain Sharpening: A sharp chainsaw chain is essential for safe and efficient cutting. Sharpen your chain regularly using a file or a chainsaw sharpener.
• Chainsaw Bar Maintenance: Keep your chainsaw bar clean and lubricated. Check the bar for wear and damage regularly.
• Tool Cleaning: Clean your tools after each use to remove dirt, sap, and other debris.
• Tool Storage: Store your tools in a dry and secure location to prevent rust and damage.
• Regular Inspection: Inspect your tools regularly for wear, damage, and loose parts. Repair or replace any damaged tools immediately.

Firewood Seasoning Techniques and Safety Considerations

Seasoning firewood is the process of drying wood to reduce its moisture content. Properly seasoned firewood burns hotter, cleaner, and more efficiently than green wood.

• Why Season Firewood? Green wood contains a high amount of moisture, which must be evaporated before the wood can burn efficiently. Burning green wood produces more smoke, creosote, and less heat than burning seasoned wood.

  • Data Point: Burning green wood can reduce the heating value by as much as 50% compared to burning seasoned wood.
  • Seasoning Time: The amount of time it takes to season firewood depends on the type of wood, the climate, and the seasoning method. Generally, hardwoods take longer to season than softwoods. In dry climates, firewood can be seasoned in as little as six months, while in humid climates, it may take a year or more.

  • Seasoning Methods: The most common method of seasoning firewood is air-drying. This involves stacking the wood in a way that allows for good air circulation. Other seasoning methods include kiln-drying and solar-drying.

  • Comparison: Kiln-drying is the fastest method of seasoning firewood, but it is also the most expensive. Air-drying is the most common and cost-effective method, but it takes longer.

  • Stacking Techniques: Proper stacking is essential for efficient seasoning. Stack the wood in a single row, with the bark side up. Leave space between the rows to allow for air circulation. Elevate the wood off the ground using pallets or cinder blocks.
  • Covering Firewood: Covering firewood can help to protect it from rain and snow, but it can also trap moisture and slow down the seasoning process. If you choose to cover your firewood, make sure to leave the sides open to allow for air circulation.

Safety Considerations:

• Stack Stability: Stack firewood in a stable manner to prevent it from collapsing.
• Pest Control: Inspect firewood for insects and pests before bringing it indoors.
• Carbon Monoxide: Ensure that your wood-burning stove or fireplace is properly vented to prevent carbon monoxide poisoning.
• Fire Safety: Keep a fire extinguisher nearby and never leave a fire unattended.
