Operate or tend machines to wash or clean products, such as barrels or kegs, glass items, tin plate, food, pulp, coal, plastic, or rubber , to remove impurities.

Add specified amounts of chemicals to equipment at required times to maintain solution levels and concentrations. Drain, clean, and refill machines or tanks at designated intervals, using cleaning solutions or water. Load machines with objects to be processed, then unload objects after cleaning and place them on conveyors or racks. Measure, weigh, or mix cleaning solutions, using measuring tanks, calibrated rods or suction tubes. Observe machine operations, gauges, or thermometers, and adjust controls to maintain specified conditions. Operate or tend machines to wash and remove impurities from items such as barrels or kegs, glass products, tin plate surfaces, dried fruit, pulp, animal stock, coal, manufactured articles, plastic, or rubber. Set controls to regulate temperature and length of cycles, and start conveyors, pumps, agitators, and machines. Adjust, clean, and lubricate mechanical parts of machines, using hand tools and grease guns. Draw samples for laboratory analysis, or test solutions for conformance to specifications, such as acidity or specific gravity. Examine and inspect machines to detect malfunctions. Record gauge readings, materials used, processing times, and/or test results in production logs.

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. Operation Monitoring -- Watching gauges, dials, or other indicators to make sure a machine is working properly.

Control Precision -- The ability to quickly and repeatedly adjust the controls of a machine or a vehicle to exact positions. 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). Near Vision -- The ability to see details at close range (within a few feet of the observer). Number Facility -- The ability to add, subtract, multiply, or divide quickly and correctly.

Controlling Machines and Processes -- Using either control mechanisms or direct physical activity to operate machines or processes (not including computers or vehicles). Handling and Moving Objects -- Using hands and arms in handling, installing, positioning, and moving materials, and manipulating things. 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. 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. Identifying Objects, Actions, and Events -- Identifying information by categorizing, estimating, recognizing differences or similarities, and detecting changes in circumstances or events. Repairing and Maintaining Mechanical Equipment -- Servicing, repairing, adjusting, and testing machines, devices, moving parts, and equipment that operate primarily on the basis of mechanical (not electronic) principles. Evaluating Information to Determine Compliance with Standards -- Using relevant information and individual judgment to determine whether events or processes comply with laws, regulations, or standards. Getting Information -- Observing, receiving, and otherwise obtaining information from all relevant sources.
