Read the first 7 Polisher & Extractor Equipment flashcards as text

  1. What is the correct way to clean a foam polishing pad between correction stages on the same vehicle?

    Answer: Use a pad cleaning brush or foam pad cleaner with the machine spinning at low speed

    Using a pad cleaning brush or dedicated cleaner while the machine spins removes compound residue without damaging foam cell structure.

  2. An extractor's 'two-tank system' design refers to which configuration?

    Answer: Separate tanks for clean solution and recovered dirty water

    Two-tank systems keep clean solution separate from dirty recovered water, preventing redepositing of soil onto surfaces.

  3. What is the purpose of the 'speed dial' or 'variable speed control' on a professional polisher?

    Answer: To adjust RPM/OPM for different products, pad types, and paint conditions

    Variable speed allows the detailer to match machine speed to the aggressiveness needed for the product, pad, and paint condition.

  4. Which symptom indicates that an extractor's recovery tank is full and requires emptying?

    Answer: Loss of suction and solution injection stops working

    A full recovery tank triggers a float shutoff valve that cuts suction to prevent overflow, causing noticeable loss of vacuum power.

  5. When polishing a vehicle's roof panel, what ergonomic consideration is most important for operator safety?

    Answer: Keep elbows bent and use body weight from the side rather than directly overhead

    Bending elbows and using lateral body weight reduces shoulder strain and prevents fatigue-related mistakes on large flat panels.

  6. What does OPM measure on a dual-action polisher, and how does it differ from RPM?

    Answer: Orbits per minute measures the orbital movement speed, while RPM measures plate rotation speed

    OPM (orbits per minute) measures how fast the backing plate travels its eccentric orbital path, while RPM refers to any spinning rotation on the axis.

  7. Which extractor dwell time practice improves cleaning results on heavily soiled automotive carpet?

    Answer: Allow cleaning solution to dwell 1–3 minutes before extracting to break down soil

    A 1–3 minute dwell time allows enzymatic or surfactant chemistry in the solution to fully penetrate and dissolve embedded soils.
