Background
The Craftsman Trimmer 316.711471 is a gardening tool designed by RYOBI / Ryobi America Corp for Sears under the Craftsman Brand. The trimmer operates on a 2-cycle, 29cc, air-cooled engine which uses a 40:1 mixture of unleaded gasoline and 2-cycle oil. It is equipped with a bump head cutting head, using a 0.095-inch diameter cutting line with a length of 12 feet. The cutting path diameter is approximately 17 inches which can be used for grass cutting, light weed removal, edging, and decorative trimming around trees and fences.
To operate the trimmer, the fuel is mixed and filled into the 10.0 oz fuel tank capacity, the primer bulb is pressed 10 times, the choke is moved to full choke position, and the starter rope is pulled while holding the throttle. During operation, the bump head allows new trimming line to be released by tapping the bump knob on the ground while running at full throttle. Routine maintenance includes cleaning and oiling the air filter every 10 hours, replacing the spark plug every 25 hours, and ensuring fresh fuel use within 30 days of mixing. The product weighs between 10-11 lbs without fuel.
