Abstract: A pneumatic tool with an air blow device. The pneumatic tool, a dual action (DA) sander, includes a nozzle and air blow valve. Compressed air is provided via a DA supply line and an air blow supply line to independently power the DA sander and the air blow device, respectively. The DA sander has an actuator for activating a tool piece including a mounting disc and sandpaper. The air blow device is activated by depressing an actuating button on the air blow valve to open the air blow valve. Layout of the tool piece and the air blow device provide for independent operation of the tool piece and the air blow device.

Abstract: A method and apparatus are provided for viewing an object (such as a coating overspray accumulation) disposed in a difficult to view area (such as the underside of a lower trough or weir of a cleaning apparatus) and for measuring a distance between first and second points on the object. The apparatus includes a laser, a mirror and a measuring instrument. The mirror reflects a laser beam generated by the laser such that the laser beam is divided into first and second portions that are disposed at a right angle to each other. The laser is moved along a measurement path to a first measurement position that places the second portion of the laser beam at the first point on the object. The laser is then moved along the measurement path to a second measurement position that places the second portion of the laser beam at the second point on the object.
