TECHNICAL DATA

Recommended original and replacement bar and chain combinations

Following is a list of recommended cutting equipment for the Jonsered chain saw models 2141, 2145 and 2150. The combinations of power head, bar and chain have been investigated in accordance with the kickback and vibration requirements of ANSI B 175.1– 2000.

The guide bar nose radius is determined by either the maximum number of teeth in the nose sprocket or the corresponding maximum nose radius of a solid bar.

The following list is the chain saw manufacturers recommendations. There may be other combinations available, which will also achieve kickback reduction.

As we are listing the maximum guide bar nose radius, you may use a guide bar with smaller nose radius than in our list. For guide bars of the same length, all sprocket-nose guide bars of the same pitch and having the same number of sprocket teeth may be considered to have equivalent kickback energy. A hard nose bar having the same length and nose radius as a sprocket-nose bar may be considered to have equivalent or less kickback energy than the sprocket-nose bar.

Low kickback saw chain is a chain which has only met the kickback performance requirements of ANSI B 175.1 safety requirements for gasoline powered chain saws when tested on the representative sample of chain saws below 3.8 cu. in. specified in ANSI 175.1. We recommend that you as a replacement use the listed chains or "Low kickback saw chains" which are available at your dealer.

CS 2141 EPA II, CS 2145 EPA II, CS 2150 EPA I specifications

The Jonsered CS 2150 EPA I, CS 2145 EPA II, and CS 2141 EPA II are premium chainsaws engineered for both professional users and serious enthusiasts. These models exemplify Jonsered's commitment to power, efficiency, and user-friendly design, making them ideal for a variety of cutting tasks, from felling trees to trimming branches.

The Jonsered CS 2150 EPA I is a robust chainsaw that offers a powerful engine combined with advanced features. It boasts a 50.2 cc engine that delivers exceptional cutting performance while adhering to strict EPA emissions standards. The chainsaw is equipped with the X-Torq engine technology, which significantly reduces fuel consumption and emissions, enabling users to work longer while minimizing environmental impact. Additionally, the CS 2150 features a high chain speed of 22.3 m/s, allowing for swift and clean cuts.

The CS 2145 EPA II further enhances performance with its lightweight design, making it easy to maneuver for prolonged use without fatigue. Powered by a 45.7 cc engine, it combines efficiency with raw power, providing reliable performance for both professionals and homeowners. The inclusion of an easy-start system means that users can start the saw with minimal effort, which is especially advantageous during colder weather or when working in challenging environments. Its validated safety features, including a chain brake and low kickback bar, ensure user protection during operation.

The CS 2141 EPA II offers a perfect balance of power and manageability. With a smaller 40.9 cc engine, it is particularly suited for users looking for an efficient saw that doesn't compromise on performance. The lightweight design allows for easy handling, particularly in dense and difficult terrain. Like the other models, it utilizes the X-Torq engine technology, which ensures reduced emissions and optimal fuel efficiency.
