Background and Identification
The Echo Brushcutter (model SRM-2620U) is a gasoline-powered brush cutter and trimmer. The brushcutter can be converted to a brush saw blade using the optional conversion kit.
The cutter includes a 20.6 fluid ounce fuel tank and a bellows-style fuel transfer system for easier engine restarts. It features a 25.4 cc two-stroke engine manufactured from magnesium that produces 1.35 horsepower. Without gasoline and oil, the cutter weighs 13.3 pounds. The attached U-handle folds to be parallel against the cutter’s body for more convenient transport and storage. The U-style handle also includes a throttle lever and tool-less adjustment. The cutter also includes an additional shield for blade use, though the blade is not generally included with purchase. The Speed-Feed 400 cutting head is designed to reload quickly and without any disassembly.
Echo recommends using a 50:1 ratio of fuel to oil mix for two-stroke cycle engines. Echo also recommends only using gasoline with a minimum octane rating of 89 or higher (mid-grade to premium). A 50:1 ratio is equal to 1 US gallon of gasoline and 2.6 fluid ounces of two-stroke engine oil.
The SRM-2620U model is “CARB compliant,” meaning that the chainsaw meets the California Air Resources Board’s rules and regulations for air pollution.
The Echo Brushcutter (model SRM-2620U) can be identified by the name “ECHO” in capital letters on the orange-colored plastic engine covering.
