545123817 specifications

The Poulan 545123817 is a robust chainsaw designed for both professional and residential use, offering a blend of power, efficiency, and ergonomics. This model is particularly noted for its reliability, making it a popular choice among homeowners and arborists alike.

One of the standout features of the Poulan 545123817 is its 50cc engine, which provides ample power for cutting through various types of wood. This capability allows users to tackle everything from small branches to larger trees, enhancing its versatility on the job. The engine is optimized for fuel efficiency, ensuring that users can work for extended periods without the need for frequent refueling.

The chainsaw utilizes a 20-inch Oregon bar and chain, providing the reach necessary for larger cutting tasks while maintaining a manageable weight. The Oregon technology ensures the chain maintains its sharpness longer, reducing the downtime spent on blade maintenance. Additionally, the design includes automatic bar and chain oil lubrication, which minimizes friction and wear, contributing to the longevity of the tool.

Ergonomics play a crucial role in the usability of the Poulan 545123817. The chainsaw features an anti-vibration system that absorbs shocks and vibrations during operation, which significantly reduces user fatigue over long cutting sessions. The front and rear handles are designed for comfort, with a grip that enhances control and maneuverability.

Safety is paramount in any chainsaw, and the Poulan 545123817 incorporates several important safety features. It includes a chain brake that automatically engages in the event of kickback, helping to prevent accidents. The chainsaw also has a low kickback chain, which reduces the force that can cause the chainsaw to jerk away from the user unexpectedly.

Another noteworthy aspect of the 545123817 is its ease of use. The chainsaw is equipped with an easy-start system that reduces the effort required to start the engine, making it more accessible to users of varying skill levels. Moreover, the model features tool-less air filter and spark plug access, which simplifies maintenance tasks, allowing users to keep the tool in top condition with minimal hassle.

In conclusion, the Poulan 545123817 is a powerful and efficient chainsaw that combines advanced technologies with practical features. Its well-balanced design, safety mechanisms, and user-friendly operation make it an excellent choice for anyone looking to accomplish cutting tasks with ease. Whether for professional landscaping or simple home projects, this chainsaw provides reliable performance that can handle a variety of challenges.
