Before diving into the intricacies of using the Husqvarna 266, let’s get familiar with its core specifications:

• Engine Displacement: 66.7 cc (4.07 cu. in.) – This is the heart of the saw, dictating its power output. A larger displacement generally means more torque for tackling tougher wood.
• Power Output: 3.6 kW (4.8 hp) – The actual usable power delivered by the engine.
• Weight (without bar and chain): Approximately 6.1 kg (13.4 lbs) – A crucial factor for handling and fatigue during extended use.
• Recommended Bar Length: 16-24 inches – Choosing the right bar length depends on the size of the wood you’re cutting.
• Chain Pitch: .325 inch or 3/8 inch – This refers to the spacing between the chain’s drive links.
• Chain Gauge: .050 inch or .058 inch – The thickness of the drive links.
• Fuel Tank Capacity: 0.7 liters (1.48 US pints)
• Oil Tank Capacity: 0.4 liters (0.85 US pints)

These specifications tell a story. The 66.7cc engine indicates a saw designed for substantial tasks. The weight, while not the lightest, suggests a balance between power and maneuverability. I remember the first time I picked up a 266. I was surprised by the weight, but also impressed by the feeling of solidity. It felt like a tool that could handle anything I threw at it.

• Power: The 66.7cc engine provides ample power for felling trees, bucking logs, and other heavy-duty tasks.
• Availability of Parts: While the saw is no longer in production, parts are still readily available online and through many chainsaw repair shops.

I’ve seen 266s that have been passed down through generations, still running strong after years of hard work. That kind of longevity is rare in modern tools.

5 Tips for Woodworkers Using the Husqvarna 266

Now that we’ve established the basics, let’s delve into practical tips for getting the most out of your Husqvarna 266.

Tip 1: Mastering Starting and Warm-up Procedures

Starting a cold 266 can sometimes be a challenge, especially if it hasn’t been used in a while. Here’s a step-by-step guide:

1. Fuel Check: Ensure the fuel tank is filled with the correct fuel mixture (typically a 50:1 ratio of gasoline to two-stroke oil). I always use a high-quality synthetic two-stroke oil to prolong engine life.
2. Choke Engagement: Engage the choke fully. This restricts airflow, creating a richer fuel mixture for starting.
3. Decompression Valve (If Equipped): If your 266 has a decompression valve, press it to reduce compression and make pulling the starter cord easier.
4. Starting Pulls: Pull the starter cord firmly and smoothly several times until the engine sputters or tries to start.
5. Choke Adjustment: Disengage the choke to the half-choke position (if available) or fully disengage it.
6. Final Pulls: Pull the starter cord again until the engine starts and runs.
7. Warm-up: Allow the engine to warm up for a few minutes before putting it under load. This ensures proper lubrication and prevents stalling.

Troubleshooting Starting Problems:

• Flooded Engine: If the engine floods (smells strongly of gasoline), remove the spark plug and pull the starter cord several times to clear excess fuel.
• Spark Plug Issues: A fouled or worn spark plug can prevent starting. Clean or replace the spark plug as needed. The correct spark plug gap for the Husqvarna 266 is typically 0.5 mm (0.020 inches).
• Fuel Line Problems: Cracked or clogged fuel lines can restrict fuel flow. Inspect and replace fuel lines as needed.

I once spent an entire morning troubleshooting a 266 that wouldn’t start. It turned out to be a combination of a fouled spark plug and a partially clogged fuel filter. Regular maintenance can prevent these issues.

Tip 2: Chain Selection and Maintenance

The chain is the cutting heart of your chainsaw. Choosing the right chain and maintaining it properly is crucial for performance and safety.

• Chain Pitch and Gauge: Ensure the chain you select matches the sprocket and bar specifications of your Husqvarna 266. As mentioned earlier, the 266 typically uses a .325 inch or 3/8 inch pitch chain with a .050 inch or .058 inch gauge.
• Chain Type: Different chain types are designed for different purposes.
  • Full Chisel: Aggressive cutting, best for clean wood.
  • Semi-Chisel: More forgiving, better for dirty or frozen wood.
  • Low-Kickback: Designed to reduce the risk of kickback, ideal for beginners.
• Chain Sharpening: A sharp chain is essential for safe and efficient cutting. Learn to sharpen your chain using a file and guide or a chain grinder. I prefer using a file and guide because it allows me to maintain the correct cutting angles and depth gauges.
  • Filing Angle: The correct filing angle for most chainsaw chains is around 30 degrees.
  • Depth Gauge Setting: The depth gauges should be filed down slightly lower than the cutting teeth to allow them to bite into the wood. The recommended depth gauge setting for the Husqvarna 266 is typically 0.635 mm (0.025 inches).
• Chain Tension: Proper chain tension is crucial for safety and performance. The chain should be snug against the bar but still able to be pulled around by hand. Adjust the tension as needed, especially when the chain is new and stretches.
• Chain Lubrication: Always ensure the chain is properly lubricated with bar and chain oil. A lack of lubrication can cause excessive wear and tear on the chain and bar. I prefer using a high-quality bar and chain oil with tackifiers to help it adhere to the chain.

I once ruined a perfectly good chainsaw bar by neglecting to lubricate the chain properly. The friction generated by the dry chain overheated the bar, causing it to warp. It was a costly lesson in the importance of lubrication.

Tip 3: Safe Felling Techniques

Felling trees is one of the most dangerous tasks you can perform with a chainsaw. Proper technique and safety precautions are essential.

1. Risk Assessment: Before felling any tree, carefully assess the surrounding area for potential hazards, such as power lines, buildings, and people.
2. Escape Routes: Plan two escape routes at a 45-degree angle away from the anticipated direction of the fall.
3. Tree Lean: Determine the tree’s natural lean. This will influence the direction of the fall.
4. Notch Cut: Cut a notch on the side of the tree facing the desired direction of fall. The notch should be about 1/5 to 1/3 of the tree’s diameter.
   • Upper Cut: Make the upper cut of the notch first, at a 45-degree angle.
   • Lower Cut: Make the lower cut of the notch horizontally, meeting the upper cut to remove the wedge of wood.
5. Hinge Wood: Leave a hinge of uncut wood between the notch and the back cut. The hinge controls the direction of the fall. The hinge should be about 1/10 of the tree’s diameter.
6. Back Cut: Make the back cut horizontally, slightly above the level of the notch. Leave the hinge wood intact.
7. Felling Wedges: If necessary, use felling wedges to help push the tree over in the desired direction. Drive the wedges into the back cut.
8. Retreat: Once the tree starts to fall, retreat quickly along your escape route.
9. Observe: Watch the tree fall and be aware of any branches or debris that may be dislodged.

Safety Gear: Always wear appropriate safety gear when felling trees, including:

• Helmet: To protect your head from falling branches.
• Eye Protection: To protect your eyes from flying debris.
• Hearing Protection: To protect your ears from the chainsaw’s noise.
• Chainsaw Chaps: To protect your legs from accidental cuts.
• Steel-Toed Boots: To protect your feet from falling logs.
• Gloves: To improve grip and protect your hands.

I once witnessed a near-fatal accident when a tree fell unexpectedly and struck a worker who wasn’t paying attention. It reinforced the importance of constant vigilance and adherence to safety protocols.

Tip 4: Bucking and Limbing Techniques

Once the tree is on the ground, you’ll need to buck it into manageable lengths and remove the branches (limbing).

• Bucking: Bucking is the process of cutting a felled tree into shorter logs.
  • Support: Ensure the log is properly supported to prevent it from pinching the chainsaw bar. Use log jacks or other supports if necessary.
  • Cutting Techniques: Use appropriate cutting techniques to avoid pinching, such as:
    • Overbucking: Cutting from the top down.
    • Underbucking: Cutting from the bottom up.
    • Boring Cut: Inserting the tip of the bar into the log to relieve tension.
• Limbing: Limbing is the process of removing branches from a felled tree.
  • Stance: Maintain a stable stance and keep both feet firmly planted on the ground.
  • Cutting Direction: Cut branches from the bottom up to avoid being struck by falling limbs.
  • Tension: Be aware of branches that are under tension and could spring back when cut.

Wood Types and Their Properties:

Understanding the properties of different wood types is crucial for both felling and bucking.

• Hardwoods: (Oak, Maple, Ash) Generally denser and harder to cut, but provide more heat when burned as firewood.
• Softwoods: (Pine, Fir, Spruce) Easier to cut, but burn faster and produce less heat.
• Green Wood vs. Seasoned Wood:
  • Green Wood: Freshly cut wood with a high moisture content. It’s heavier and harder to split.
  • Seasoned Wood: Wood that has been allowed to dry, reducing its moisture content. It’s lighter, easier to split, and burns more efficiently.

I once tried to buck a large oak log that was improperly supported. The log pinched the bar, causing the chainsaw to kick back violently. Fortunately, I was wearing proper safety gear and wasn’t injured, but it was a close call.

Tip 5: Maintaining Your Husqvarna 266

Regular maintenance is key to keeping your Husqvarna 266 running smoothly and reliably.

• Air Filter: Clean or replace the air filter regularly to ensure proper airflow to the engine. A dirty air filter can reduce power and cause the engine to overheat. I typically clean the air filter after every 5-10 hours of use.
• Spark Plug: Inspect and clean or replace the spark plug as needed. A fouled or worn spark plug can cause starting problems and reduce engine performance. The correct spark plug gap for the Husqvarna 266 is typically 0.5 mm (0.020 inches).
• Fuel Filter: Replace the fuel filter annually or more frequently if you notice fuel flow problems. A clogged fuel filter can restrict fuel flow and cause the engine to stall.
• Bar and Chain Oil: Use a high-quality bar and chain oil with tackifiers to help it adhere to the chain. Check the oil level frequently and refill as needed.
• Bar Maintenance: Clean the bar groove regularly to remove sawdust and debris. Check the bar rails for wear and dress them with a file if necessary.
• Sprocket: Inspect the sprocket for wear and replace it as needed. A worn sprocket can damage the chain.
• Carburetor Adjustment: If the engine is running poorly, you may need to adjust the carburetor. Consult the owner’s manual for instructions. I recommend taking it to a qualified technician if you’re not comfortable doing it yourself.
• Storage: When storing your chainsaw for an extended period, drain the fuel tank and run the engine until it stalls to prevent fuel from gumming up the carburetor. Store the chainsaw in a dry place.

Cost Considerations:

• Fuel and Oil: Factor in the cost of fuel and bar and chain oil when budgeting for chainsaw use.
• Maintenance Parts: Budget for replacement parts such as air filters, spark plugs, fuel filters, and chains.
• Repair Costs: Be prepared for potential repair costs, especially if you’re using an older chainsaw.

I’ve learned that preventative maintenance is far cheaper than major repairs. Taking the time to clean and inspect my chainsaw after each use has saved me a lot of money and downtime over the years.

Case Studies in Firewood Preparation

Let’s look at some real-world examples of how these techniques can be applied in firewood preparation.

Case Study 1: Efficiently Splitting Hardwood

Scenario: A homeowner needs to split a large quantity of oak firewood.

Challenge: Oak is a dense hardwood that can be difficult to split by hand.

Solution: Use a hydraulic log splitter.

• Log Splitter Selection: Choose a log splitter with sufficient tonnage for the size and type of wood being split. A 20-ton or greater splitter is recommended for oak.
• Technique: Position the log on the splitter and engage the hydraulic ram. Split the log in half, then repeat the process until the desired size is achieved.
• Safety: Always wear eye protection and gloves when operating a log splitter. Keep hands and feet clear of the splitting area.

Benefits: A hydraulic log splitter significantly reduces the effort and time required to split hardwood.

Case Study 2: Stacking Firewood for Optimal Drying

Scenario: A homeowner wants to season firewood quickly and efficiently.

Challenge: Firewood needs to be stacked in a way that promotes airflow and prevents moisture buildup.

Solution: Use a proper stacking technique.

• Location: Choose a sunny, well-ventilated location for stacking firewood.
• Base: Create a base of gravel or pallets to keep the firewood off the ground.
• Stacking Method: Stack the firewood in rows, leaving gaps between the rows for airflow. Consider using a “holzhaufen” (round stack) for stability and aesthetics.
• Covering: Cover the top of the stack with a tarp to protect it from rain and snow, but leave the sides open for ventilation.

Drying Times:

• Softwoods: Typically season in 6-12 months.
• Hardwoods: Typically season in 12-24 months.

Moisture Content Targets:

• Optimal Moisture Content for Burning: 15-20%

Benefits: Proper stacking promotes faster drying and reduces the risk of mold and rot. Seasoned firewood burns more efficiently and produces less smoke.

I experimented with different firewood stacking methods over the years. I found that the holzhaufen method, while time-consuming to build, provided excellent stability and airflow.
