Old Jonsered Chainsaw Models (5 Tips to Identify Vintage Saws)

Adaptability is the name of the game, whether you’re felling timber in the Pacific Northwest or prepping firewood in a small European village. Over the years, I’ve learned that nothing stays the same in the world of wood processing. But some things, like the quality and legacy of old Jonsered chainsaws, are worth preserving and understanding. That’s why I’m diving deep into identifying vintage Jonsereds, sharing my practical tips and hard-earned wisdom to help you appreciate these iconic machines.

Old Jonsered Chainsaw Models (5 Tips to Identify Vintage Saws)

The allure of vintage chainsaws is undeniable. They’re relics of a bygone era, built with a robustness and simplicity rarely seen today. Jonsereds, in particular, hold a special place in the hearts of many loggers and woodworkers. But identifying these old workhorses can be tricky. That’s where my five tips come in.

1. Deciphering the Model Number: Your First Clue

The first, and often most straightforward, way to identify an old Jonsered chainsaw is by its model number. These numbers, usually stamped or printed on a plate attached to the saw’s body, are your key to unlocking its history.

• Location: Look for a metal plate or sticker, often near the handle, starter, or on the engine casing.
• Format: Older Jonsereds typically have two- or three-digit model numbers, sometimes followed by a letter or two. Examples include the Jonsered 52, 621, 80, or 90. More recent models might have more complex alphanumeric designations.
• Resources: Once you have the number, online resources like chainsaw collector forums, vintage chainsaw part suppliers, and even Jonsered’s own archives (if accessible) can help you pinpoint the exact model and its production years. I’ve personally used sites like Chainsaw Collectors Corner to cross-reference model numbers and learn about specific features.
• Example: Finding a model number “Jonsered 80” immediately tells you it’s likely a saw from the 1960s or 70s, known for its powerful engine and robust construction.

Personal Story: I remember once stumbling across a Jonsered 621 hidden in a friend’s barn. The model number was barely legible, covered in years of grime. But after a careful cleaning and some online research, I discovered it was a late 1970s model, a real gem!

2. Examining the Design and Aesthetics: A Visual Timeline

The design of a chainsaw can tell a story about its age. Jonsereds, like any product line, evolved over time, with distinct visual characteristics marking different eras.

• Early Models (Pre-1960s): These saws often feature a more rounded, bulky design. They might have exposed carburetors and simpler air filtration systems. Look for metal fuel tanks and a more “industrial” look.
• 1960s-1970s: This era saw the introduction of more streamlined designs and the use of plastics in some components. Color schemes often included orange and black, which became a Jonsered trademark. Features like chain brakes and anti-vibration systems began to appear.
• 1980s-1990s: Saws from this period are typically more ergonomic, with improved vibration dampening and safety features. Plastic components became more prevalent, and the overall design became more refined.
• Post-1990s: These models often feature electronic ignition systems, catalytic converters, and other modern technologies aimed at improving efficiency and reducing emissions.

Data Point: In the 1970s, Jonsereds introduced the “vibration damping system,” a revolutionary feature at the time, significantly reducing operator fatigue. This is a key visual clue when dating a saw.

Insight: Pay attention to the placement of the carburetor and air filter. Older models often have these components more exposed, while newer saws have them integrated into the engine housing.

3. Identifying Key Features and Technologies: A Technical Deep Dive

Beyond the overall design, specific features and technologies can help you narrow down the age of a Jonsered chainsaw.

• Chain Brake: Chain brakes became mandatory safety features in many countries during the 1970s and 1980s. The presence of a functional chain brake is a good indicator that the saw is from this era or later.
• Anti-Vibration System: As mentioned earlier, Jonsereds were pioneers in vibration damping. Look for rubber mounts or springs between the engine/cutting unit and the handles. The complexity and effectiveness of the system can indicate the saw’s age.
• Ignition System: Older saws typically used points and condenser ignition systems. Newer models use electronic ignition (CDI). The type of ignition system is usually discernible by examining the wiring and components near the flywheel.
• Carburetor Type: The type of carburetor can also be a clue. Older saws often used simpler carburetors with fewer adjustments. Newer saws might have more sophisticated carburetors with adjustable high- and low-speed needles.

Practical Tip: If you can access the spark plug, check its size and thread type. This can sometimes be used to cross-reference with parts catalogs and determine the engine’s approximate age.

Case Study: I once restored a Jonsered 621. By examining the carburetor and comparing it to diagrams in an old service manual, I was able to confirm it was an original part and helped me estimate the saw’s production year more accurately.

4. Checking for Original Markings and Decals: The Devil is in the Details

Original markings, decals, and labels can provide valuable clues about a Jonsered chainsaw’s age and origin.

• Manufacturer’s Labels: Look for labels indicating the manufacturer (Jonsereds AB, Sweden) and the model number. These labels might be faded or damaged, but even partial information can be helpful.
• Safety Decals: Safety decals often changed over time to reflect evolving safety standards. Comparing the decals to those on other vintage saws can help you estimate the production year.
• “Made in Sweden” Markings: Most Jonsereds were manufactured in Sweden. The presence of a “Made in Sweden” marking is a good indicator of authenticity.
• Dealership Stickers: Sometimes, you’ll find stickers from the original dealership that sold the saw. These stickers can provide a geographical context and, in some cases, even the year of sale.

Warning: Be wary of fake or reproduction decals. These are sometimes used to artificially inflate the value of a saw. Compare the quality and appearance of the decals to those on known original saws.

Insight: Pay close attention to the font and style of the markings. These details can change over time and can be used to differentiate between different production runs.

5. Consulting with Experts and Online Communities: Wisdom of the Crowd

When in doubt, don’t hesitate to consult with experts and online communities. The vintage chainsaw world is full of knowledgeable enthusiasts who are happy to share their expertise.

• Chainsaw Collector Forums: These forums are a treasure trove of information. You can post photos of your saw and ask for help identifying it. Members often have access to catalogs, service manuals, and other resources that can be invaluable.
• Vintage Chainsaw Parts Suppliers: These suppliers often have extensive knowledge of old chainsaws and can help you identify models and locate parts.
• Local Chainsaw Repair Shops: Older repair shops might have mechanics who are familiar with vintage Jonsereds. They might be able to provide insights based on their experience.
• Online Auctions and Classifieds: Examining photos and descriptions of similar saws being sold online can help you identify your model.

Personal Story: I once spent hours scouring online forums trying to identify a particular Jonsered model. Finally, a member pointed me to an obscure Swedish website that contained a catalog from the 1960s. It was a breakthrough!

Data Point: According to a recent survey of chainsaw collectors, online forums are the most popular resource for identifying vintage saws, with 75% of collectors using them regularly.
