Background
The Craftsman Trimmer 316.791890 is a gas-powered string trimmer produced by Ryobi America Corp for Sears. It functions with a 31.5 cc air-cooled 2-cycle engine and utilizes MAX FIRE electronic ignition. The trimmer is designed for cutting grass and light weeds, featuring a Craftsman Convertible attachment system which allows it to be transformed for use with a variety of other attachments such as a cultivator, blade edger, blower, brush cutter, and pruner.
The trimmer operates with a 40:1 ratio of unleaded gasoline and 2-cycle oil, with a fuel tank capacity of 13 oz for extended periods of use between refueling. Starting the trimmer involves priming the fuel bulb, pulling the starter rope, and squeezing the throttle trigger, with an Incredi-Pull starter feature to reduce the effort needed to start the engine. It comes equipped with a Hassle Free III spiral line cutting head and utilizes Craftsman's XTRA QUIET spiral line in .095 and .155 inch diameters, with a 14 inch cutting path for efficient edging and trimming tasks.
