Background
The Craftsman Trimmer 316.711370 is a gas-powered string trimmer produced by Sears Brands. It utilizes a 25cc 2-cycle air-cooled engine and is fitted with a starting system that is designed to make pull starts less strenuous.
This trimmer operates with a specific idle and operating RPM, uses a Champion RDJ7J equivalent spark plug, and requires a fuel/oil ratio of 40:1. It has a fuel tank capacity of 10 oz and weighs between 10 and 11 lbs without fuel. The trimmer mechanism is a bump head, which allows for the release of the line without the need to stop the engine. It uses a line with a diameter of 0.095 inches and has a cutting path diameter of 17 inches. The trimmer is started by adding a fuel mixture, pressing the primer bulb, adjusting the choke, and pulling the starter rope. It is stopped by releasing the throttle trigger and switching the on/off switch to the off position. Maintenance involves cleaning and re-oiling the air filter, checking or replacing the spark plug, using fresh unleaded gasoline with a 2-cycle oil mix, and replacing the trimmer line as needed.
