b. clean and lubricate the equipment (when applicable)
c. inspect the equipment for wear and damage
d. both b and c

1. a customer is experiencing vibrations when braking. technician a says they should use the brake lathe to address the issue. technician b says to use the wheel balancer. who is correct?

a. technician a only
b. technician b only
c. both technician a and b
d. neither technician a or b

Explanation:

1. Without specific classroom - taught knowledge, it's hard to answer about the air - compressor step. But generally, draining moisture and turning off the power might be steps.
2. The primary function of a hydraulic press in a shop is to apply high force for tasks like bending, pressing, or forming metal parts.
3. To store a shop creeper safely, it should be placed in a designated area, preferably upright or flat to avoid tripping hazards.
4. Jack stands are used when lifting a car with a jack to provide a stable support in case the jack fails.
5. One main reason a vehicle may fall off a hoist is improper positioning or malfunction of the hoist's locking mechanism.
6. The purpose of a brake lathe is to machine the brake rotors or drums to restore a smooth, flat surface for proper braking performance.
7. A customer might require a wheel balancer if they experience vibrations while driving, which could be due to unbalanced wheels.
8. Using a floor jack without jack stands is considered too dangerous as the jack can slip or fail. So d. Neither a nor b (since both floor jack and drive - on ramps need proper support and precautions).
9. Technicians' responsibilities regarding shop equipment include cleaning, lubricating (when applicable), and inspecting for wear and damage. So d. Both B and C.
10. If a customer is experiencing vibrations when braking, both using a brake lathe (if the rotors are warped) and a wheel balancer (if the wheels are unbalanced) could be appropriate. So c. Both technician A and B.

Answer:

1. Answer depends on classroom - taught knowledge.
2. To apply high force for metal - working tasks.
3. Place in a designated area, preferably upright or flat.
4. To provide stable support in case the jack fails.
5. Improper positioning or hoist locking mechanism malfunction.
6. To machine brake rotors or drums for proper braking.
7. Experiencing vibrations while driving.
8. d. Neither a nor b
9. d. Both B and C
10. c. Both technician A and B
