• Read technical manuals to understand equipment and controls
• Disassemble machinery and equipment when there is a problem
• Repair or replace broken or malfunctioning components
• Perform tests and run initial batches to make sure that the machine is running smoothly
• Detect minor problems by performing basic diagnostic tests
• Test malfunctioning machinery to determine whether major repairs are needed
• Adjust and calibrate equipment and machinery to optimal specifications
