As spring breathes new life into the world, it also brings its own set of challenges for professionals relying on gas-powered cut-off saws. The efficiency of these powerful tools can be significantly impacted by fuel-related issues, requiring users to be proactive in addressing and preventing problems. In this blog, we'll delve into the key fuel-related challenges faced by users of gas-powered cut-off saws during the spring season and explore valuable insights from experts at STIHL.

Ethanol Concerns

One of the primary culprits behind fuel-related issues in gas-powered cut-off saws is ethanol. As the temperatures rise in spring, ethanol-blended fuels become more prevalent. Ethanol has the tendency to absorb water, leading to phase separation and formation of a corrosive ethanol-water mixture. This mixture can wreak havoc on the engine, causing poor performance and potential damage. STIHL advises users to use fresh, high-quality gasoline with no more than 10% ethanol content. This proactive measure can significantly reduce the risk of fuel-related problems and ensure optimal performance of the cut-off saw.


Fuel Stabilization

Spring is a season of fluctuating temperatures, and fuel left in the saw's tank can be susceptible to degradation. Fuel stabilization becomes crucial to prevent varnish and gum buildup in the carburetor, which can clog fuel passages and hinder the proper functioning of the saw. STIHL recommends the use of fuel stabilizers to keep the fuel fresh during periods of inactivity. Adding a stabilizer to the fuel tank before storing the saw can extend the fuel's shelf life and contribute to a trouble-free start when the saw is needed again.

Air Filtration

The spring season often brings an abundance of pollen and debris, posing a challenge for the air filtration system of gas-powered cut-off saws. A clogged air filter can lead to reduced engine power and increased fuel consumption. Regular maintenance is key to overcoming this challenge. STIHL advises users to clean and inspect the air filter frequently, replacing it if necessary. This simple yet effective practice ensures that the saw's engine receives a clean and uninterrupted air supply, promoting optimal performance

Storage Practices

Proper storage of gas-powered cut-off saws during the spring season plays a crucial role in preventing fuel-related issues. STIHL emphasizes the importance of emptying the fuel tank and running the saw until it stalls before storing it for an extended period. This prevents stale fuel from gumming up the carburetor and fuel lines.

By following the expert advice from STIHL and adopting proactive measures such as using ethanol-free fuel, stabilizing fuel, maintaining air filtration, and practicing proper storage, professionals can confidently navigate the season's challenges and make the most of their powerful cutting tools.
