Background
The Craftsman Trimmer 316.791810 is a string trimmer that uses a 31.5 cc 2-stroke gasoline engine for power. This engine operates the trimmer at a speed of 7200+ rpm, while the idle speed ranges from 2800 to 3600 rpm. The fuel tank capacity is 13 oz and uses a 40:1 gasoline/oil mix. The trimmer uses an electronic ignition system and a diaphragm carburetor. The trimmer is started using a recoil starter with an auto rewind feature.
The trimmer has a cutting width of 14 inches and uses Hassle Free III spiral line to trim grass and light weeds. The trimmer is also equipped with a Twist and Edge coupler which allows the unit to convert to an edger and an edge guide wheel that can be used as a depth guide along walls. The D-handle provides a comfortable grip and is adjustable to user preference. The maintenance of the trimmer involves cleaning and oiling the air filter every 10 hours, checking and replacing the spark plug if needed every 25 hours, and using fresh unleaded gasoline mixed with 2-cycle oil at a 40:1 ratio in the fuel tank. The idle speed can be adjusted through the air filter cover and the spark arrestor screen should be checked and cleaned to prevent clogging.
