The employee places a print head in a jig on the work surface.
Employee then inserts springs using pinch grips all around the circumference of the head.
Employee then uses an automatic screwdriver to tighten the screws down. While inserting the springs, the employee had the left wrist extended to approximately 80 degrees. Such extension together with the observed force of the operation and the repetitive nature of the task are associated with cumulative trauma syndrome. Provide a lower jig or slot in the work surface to allow the employee to have neutral wrists while performing this operation. The forearms of the employee are in constant contact with a sharp edge of the work surface.
