Stihl brand and other weed trimmers use a two- stroke engine, meaning the engine completes one combustion cycle in a single turn of the crank shaft. I just found this information on how Stihl gets the abbreviations for their products. To help you identify model features, look for these corresponding symbols: C = Comfort feature, E = Easy2Start™, R = loop handle, and X = lightweight version.Ĭorrespondingly, what does FS stand for Stihl? One may also ask, what does the R mean on Stihl trimmers? In short, our professional trimmers don't mess around. The model and serial numbers are printed on the opposite side of the motor housing. All current serial numbers will be nine digits long and begin with the numbers 1, 2, 5, 8 or 9.Īlso, where is serial number on WORX trimmer? On professional units and brushcutters it is on the bar code label and stamped in the top of the cylinder or main crank case. On homeowner trimmers, it is located on the bar code label on the fan casing.
