Question 1: What is the primary purpose of regular equipment maintenance?
- To ensure safe and reliable operation while extending equipment lifespan (Correct answer)
- To create work for maintenance staff
- To comply with warranty requirements only
- To reduce equipment utilization rates
Correct answer: To ensure safe and reliable operation while extending equipment lifespan
Regular maintenance prevents breakdowns, ensures safety, and extends the useful life of equipment.
Question 2: What should be done before operating any unfamiliar equipment?
- Read the operators manual and receive proper training (Correct answer)
- Try it out and learn by trial and error
- Ask a colleague for a brief verbal overview
