Spaces and adjusts mill rolls and fits shims on shafts according to specifications, using gauges, rules, and handtools. Sets trigger mechanism which actuates cut-off die to specified length by setting and tightening setscrews. Feeds end of coil onto guide table and actuates shear to square end of coil. Actuates controls on panel to thread lead end of coil through mill. Inspects first piece for variation from rolling or length specifications and makes necessary adjustments to mill. Starts mill for automatic operation and controls speed from control panel. Adjusts valves to control flow of coolant on metal and observes operation of lubrication system.
