The Indomitable Husqvarna 266: 5 Key Features Every Logger Knows

The Husqvarna 266 isn’t the newest model on the market, but it’s a legend for a reason. Its rugged design and powerful engine make it a favorite for those who need a reliable saw that can take a beating. Let’s delve into the key features that make it a standout.

1. The Heart of the Beast: Engine Power and Performance

At the core of any chainsaw is its engine, and the Husqvarna 266 boasts a robust 61.5cc two-stroke engine. This isn’t just a number; it translates to real-world cutting power.

• Displacement: 61.5 cc (3.75 cu. in.)
• Power Output: Around 3.6 hp (2.7 kW) – This is crucial because it determines how easily the saw can handle different wood types and diameters.
• Maximum Engine Speed: Approximately 12,500 RPM. While you won’t run it at this speed constantly, it indicates the engine’s potential for quick acceleration and efficient cutting.

My Experience: I recall a project where we were clearing a patch of land overgrown with seasoned oak, some logs reaching diameters of 24 inches. Newer, less powerful saws struggled, but the 266 chewed through them with relative ease. This is where the engine displacement and power output truly shine. It allows for consistent performance even when bucking large-diameter, dense hardwoods.

Technical Insight: The two-stroke engine design means you need to mix oil with the gasoline. A typical ratio is 50:1 (gasoline to oil), but always consult the manufacturer’s manual for the specific recommendation. Using the wrong ratio can lead to engine damage. I’ve seen firsthand what happens when someone uses too little oil – seized pistons and a very unhappy chainsaw.

Data Point: A study by the Swedish University of Agricultural Sciences (SLU) on chainsaw performance showed that chainsaws with engine displacements between 60cc and 70cc are generally optimal for felling trees up to 20 inches in diameter. The 266 fits perfectly into this sweet spot.

2. Bar and Chain: The Cutting Edge

The bar and chain are the direct interface with the wood, and the Husqvarna 266 is versatile in its compatibility.

• Bar Length: Typically ranges from 16 to 24 inches. This is where personal preference and the type of work come into play.
  • 16-18 inches: Ideal for limbing and smaller trees.
  • 20-24 inches: Better for felling larger trees and bucking bigger logs.
• Chain Pitch: Usually .325″ or 3/8″. The pitch refers to the distance between the rivets on the chain.
  • .325″: Offers a good balance of speed and smoothness.
  • 3/8″: More aggressive and better suited for larger wood and tougher conditions.
• Chain Gauge: Typically .050″ or .058″. This refers to the thickness of the drive links that fit into the bar groove.

My Experience: I prefer a 20-inch bar with a 3/8″ pitch chain for most of my work. It’s a good compromise between maneuverability and cutting capacity. I once tried using a longer bar (24 inches) on smaller trees, and it felt unwieldy and inefficient. Choosing the right bar length for the job is crucial.

Technical Insight: Chain sharpness is paramount. A dull chain not only makes cutting harder but also increases the risk of kickback. Invest in a good chainsaw file and learn how to sharpen your chain properly. I recommend filing after every tank of gas to maintain optimal cutting performance.

Data Point: Oregon, a leading manufacturer of chainsaw chains, recommends sharpening chains when they lose their ability to pull themselves into the wood. A sharp chain should produce consistent chips, while a dull chain will produce sawdust.

Practical Applications and Considerations

Now that we’ve covered the key features, let’s look at some practical applications and considerations for using the Husqvarna 266.

Wood Selection Criteria

Choosing the right wood is crucial for various applications, from firewood to construction.

• Hardwoods vs. Softwoods: Hardwoods (oak, maple, ash) are denser and burn longer, making them ideal for firewood. Softwoods (pine, fir, spruce) are easier to cut and ignite, but burn faster.
• Moisture Content: For firewood, the moisture content should be below 20%. Wet wood is difficult to ignite, produces less heat, and creates more smoke.
• Log Dimensions: Consider the size and shape of the logs. Straight, uniform logs are easier to process.

My Experience: I always prefer hardwoods for firewood. They provide more heat and last longer in the stove. I use a moisture meter to ensure the wood is properly seasoned before burning it. I’ve learned the hard way that burning wet wood is a waste of time and energy.

Technical Insight: Wood moisture content can be measured using a moisture meter. These devices use electrical resistance to determine the moisture content of the wood. A reading below 20% indicates that the wood is dry enough to burn.

Data Point: The US Department of Energy recommends that firewood be seasoned for at least six months to reduce the moisture content below 20%. Seasoning involves splitting the wood and stacking it in a well-ventilated area.

Tool Calibration Standards

Maintaining proper tool calibration is essential for safety and efficiency.

• Chain Tension: The chain should be properly tensioned to prevent derailment and kickback.
• Carburetor Adjustment: The carburetor should be adjusted to ensure proper fuel-air mixture.
• Spark Plug Gap: The spark plug gap should be set to the manufacturer’s specifications.

My Experience: I always check the chain tension before each use. A loose chain can derail and cause serious injury. I also make sure the carburetor is properly adjusted to ensure the engine runs smoothly.

Technical Insight: Chain tension can be adjusted by loosening the bar nuts and turning the tensioning screw. The chain should be snug against the bar but still able to be pulled around by hand. The carburetor can be adjusted by turning the high and low speed adjustment screws. Consult the manufacturer’s manual for the specific adjustment procedure.

Data Point: The Husqvarna 266 service manual recommends that the chain tension be checked after every 15 minutes of use. The carburetor should be adjusted by a qualified technician.

My Experience: I never operate a chainsaw without wearing all of the required safety equipment. I’ve seen firsthand the devastating consequences of not wearing proper PPE.

Technical Insight: Chainsaw chaps are designed to stop the chain instantly if it comes into contact with the leg. They are made of multiple layers of ballistic nylon that clog the chain and prevent it from cutting through the fabric.

Data Point: A study by the Consumer Product Safety Commission (CPSC) found that chainsaw chaps can reduce the risk of leg injuries by up to 90%.

Case Study: Firewood Production Project

I once undertook a project to produce firewood for a local community center. The project involved felling trees, bucking logs, splitting wood, and stacking it for seasoning.

• Tree Selection: We selected trees that were dead, dying, or diseased. This helped to improve the health of the forest and provided a valuable resource for the community.
• Felling: We used the Husqvarna 266 to fell the trees. We followed proper felling techniques to ensure the trees fell in a safe direction.
• Bucking: We bucked the logs into firewood lengths (typically 16 inches). We used a chainsaw to cut the logs to length.
• Splitting: We split the wood using a hydraulic log splitter. This made the process much faster and easier than splitting the wood by hand.
• Stacking: We stacked the wood in a well-ventilated area to allow it to season properly.

Technical Details:

• Wood Type: Predominantly oak and maple.
• Moisture Content: Initial moisture content ranged from 30% to 40%. After six months of seasoning, the moisture content dropped below 20%.
• Production Volume: We produced approximately 10 cords of firewood.
• Timeframe: The project took approximately three months to complete.

Lessons Learned:

• Proper planning and organization are essential for a successful firewood production project.
• Using the right tools and equipment can significantly improve efficiency.
