Feed materials into or remove materials from machines or equipment that is automatic or tended by other workers.

Add chemicals, solutions, or ingredients to machines or equipment as required by the manufacturing process. Load materials and products into machines and equipment, or onto conveyors, using hand tools and moving devices. Push dual control buttons and move controls in order to start, stop, or adjust machinery and equipment. Remove materials and products from machines and equipment, and place them in boxes, trucks or conveyors, using hand tools and moving devices. Shovel or scoop materials into containers, machines, or equipment for processing, storage, or transport. Transfer materials and products to and from machinery and equipment, using industrial trucks or hand trucks. Clean and maintain machinery, equipment, and work areas to ensure proper functioning and safe working conditions. Fasten, package, or stack materials and products, using hand tools and fastening equipment. Identify and mark materials, products, and samples, following instructions. Inspect materials and products for defects, and to ensure conformance to specifications. Open and close gates of belt and pneumatic conveyors on machines that are fed directly from preceding machines. Record production and operational data, such as amount of materials processed. Weigh or measure materials or products to ensure conformance to specifications.

Production and Processing -- Knowledge of raw materials, production processes, quality control, costs, and other techniques for maximizing the effective manufacture and distribution of goods.

Operation and Control -- Controlling operations of equipment or systems. Equipment Maintenance -- Performing routine maintenance on equipment and determining when and what kind of maintenance is needed.

Manual Dexterity -- The ability to quickly move your hand, your hand together with your arm, or your two hands to grasp, manipulate, or assemble objects. Trunk Strength -- The ability to use your abdominal and lower back muscles to support part of the body repeatedly or continuously over time without 'giving out' or fatiguing. Static Strength -- The ability to exert maximum muscle force to lift, push, pull, or carry objects. Extent Flexibility -- The ability to bend, stretch, twist, or reach with your body, arms, and/or legs. Control Precision -- The ability to quickly and repeatedly adjust the controls of a machine or a vehicle to exact positions. Multilimb Coordination -- The ability to coordinate two or more limbs (for example, two arms, two legs, or one leg and one arm) while sitting, standing, or lying down. It does not involve performing the activities while the whole body is in motion. Category Flexibility -- The ability to generate or use different sets of rules for combining or grouping things in different ways. Information Ordering -- The ability to arrange things or actions in a certain order or pattern according to a specific rule or set of rules (e.g., patterns of numbers, letters, words, pictures, mathematical operations). Problem Sensitivity -- The ability to tell when something is wrong or is likely to go wrong. It does not involve solving the problem, only recognizing there is a problem. Dynamic Strength -- The ability to exert muscle force repeatedly or continuously over time. This involves muscular endurance and resistance to muscle fatigue.

Handling and Moving Objects -- Using hands and arms in handling, installing, positioning, and moving materials, and manipulating things. Performing General Physical Activities -- Performing physical activities that require considerable use of your arms and legs and moving your whole body, such as climbing, lifting, balancing, walking, stooping, and handling of materials. Inspecting Equipment, Structures, or Material -- Inspecting equipment, structures, or materials to identify the cause of errors or other problems or defects. Monitor Processes, Materials, or Surroundings -- Monitoring and reviewing information from materials, events, or the environment, to detect or assess problems. Controlling Machines and Processes -- Using either control mechanisms or direct physical activity to operate machines or processes (not including computers or vehicles).
