🔍 Key Concepts

• Machine safety procedures before adjusting equipment • Function of the lathe spindle and what changing spindle speed affects • Difference between stopping rotation vs. changing feeds or clutches

💭 Think About

• Ask yourself: which action makes it impossible for the cutting tool or chuck to be moving while you adjust speeds? • Which levers or controls are related to feed direction or engagement rather than actually stopping motion? • On a real lathe in a shop, what is the very first safety step your instructor would insist on before touching speed controls?

✅ Before You Answer

• Verify which choice positively ensures no rotation of the work or chuck during the speed change • Identify which options deal with feed mechanisms (not speed) and eliminate them • Confirm which control your training materials list as the primary lockout or safe condition before changing spindle speed
