CD Polisher & Extractor Equipment 5

Question 1

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

Accepted Answer

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

Answer

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

Question 2

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

Accepted Answer

Separate tanks for clean solution and recovered dirty water

Answer

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

Question 3

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

Accepted Answer

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

Answer

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

Question 4

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

Accepted Answer

Loss of suction and solution injection stops working

Answer

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

Question 5

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

Accepted Answer

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

Answer

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