Jonsereds Fabrikers AB, founded in Sweden in 1832, initially focused on manufacturing equipment for the textile industry.

Their early chainsaws were known for their robust construction, powerful engines, and pioneering features like vibration dampening.

I remember my grandfather telling me stories about the early days of logging, when Jonsered chainsaws were considered the gold standard. The reliability and power of these machines made them indispensable tools for loggers working in the harsh Scandinavian forests.

Key Features of Vintage Jonsered Chainsaws

Before diving into specific models, let’s examine the key features that distinguish vintage Jonsered chainsaws from their modern counterparts.

Engine Design: Most vintage Jonsered chainsaws feature two-stroke engines, known for their high power-to-weight ratio.
Construction Materials: These chainsaws were typically built with heavy-duty materials like cast iron and steel, ensuring durability and longevity.
Vibration Dampening: Jonsered was a pioneer in vibration dampening technology, incorporating rubber mounts and other features to reduce operator fatigue.
Carburetor Design: Early models often used Tillotson or Walbro carburetors, known for their reliability and ease of adjustment.
Ignition Systems: Magneto ignition systems were common in vintage Jonsered chainsaws, providing a reliable spark for combustion.
Chain Brakes: While not all vintage models had chain brakes, those that did were often considered ahead of their time in terms of safety.

Identifying Specific Jonsered Models

Now, let’s move on to the exciting part: identifying specific vintage Jonsered chainsaw models. Here, I’ll share some expert tips based on my own experiences and research.

Step 1: Locate the Model Number

The first step in identifying a vintage Jonsered chainsaw is to locate the model number. This is typically found on a metal plate or sticker attached to the engine housing or chassis.

Common Locations: Check the side of the engine, the top of the fuel tank, or the area around the handle.
Format: Model numbers usually consist of a series of numbers and sometimes letters (e.g., Jonsered 621, Jonsered 801).
Example: On my old Jonsered 52E, the model number is stamped on a small plate near the carburetor.

Step 2: Consult Online Resources

Once you have the model number, the next step is to consult online resources. Several websites and forums specialize in vintage chainsaws, providing valuable information and images.

Chainsaw Collectors Corner: This website is a treasure trove of information, with detailed specifications and photos of various Jonsered models.
Arboristsite.com: This forum has a dedicated section for chainsaws, where you can ask questions and get help from experienced collectors.
VintageMachinery.org: While not exclusively focused on chainsaws, this website has a wealth of information on vintage machinery, including Jonsered models.

Step 3: Compare Features and Specifications

With the model number in hand, compare the features and specifications of your chainsaw to those listed in online resources.

Engine Size: Match the engine displacement (cc) to the specifications for that model.
Bar Length: Note the original bar length, as this can help narrow down the possibilities.
Cosmetic Features: Pay attention to details like the color scheme, handle design, and placement of logos.
Unique Components: Look for unique components or features that are specific to certain models.

Step 4: Examine the Carburetor and Ignition System

The carburetor and ignition system can provide valuable clues about the age and model of your Jonsered chainsaw.

Carburetor Type: Note the make and model of the carburetor (e.g., Tillotson HS series, Walbro WA series).
Ignition System: Determine whether the chainsaw has a points-based ignition system or an electronic ignition system.
Example: My Jonsered 70E has a Tillotson HS-143A carburetor, which is consistent with the specifications for that model.

Step 5: Check for Serial Numbers

Some vintage Jonsered chainsaws have serial numbers, which can provide additional information about their production date and history.

Location: Serial numbers are typically found on the engine housing or chassis, often near the model number.
Dating: While not always possible, some serial numbers can be used to estimate the production date of the chainsaw.
Records: Contacting Jonsered or a vintage chainsaw expert may help you trace the history of your chainsaw based on its serial number.
