Background
The Craftsman 3-inch Belt Sander, model number 315.11720, is a handheld electric sander that is capable of sanding various materials including wood, metal, and plastics. The product, manufactured by Diehl Mfg Co for Sears under the Craftsman brand, is equipped with a 3-inch wide sanding belt powered by a 1/3 HP motor. It operates on a standard 120V AC current and weighs 5 lbs. It also features an auxiliary front handle for two-handed operation, belt tracking adjustment, and an on/off trigger switch.
The design of the sander allows for balanced handling, either with one or two hands, depending on the user's preference. The auxiliary front handle adds an extra dimension of control, enabling the user to keep the sanding surface flat against the workpiece. The sander has adjustable belt tracking, which can be set by turning a screw on the side of the sander while it is running. This helps keep the sanding belt centered and running smoothly. The sander also has a double insulation feature, which means that all exposed metal parts are isolated from internal components, eliminating the need for an external ground connection.
