CTE Preventive Maintenance Procedures 3 — Questions and Answers
Question 1: Which factor most directly determines the frequency of preventive maintenance for CTE shop equipment?
- The age of the building housing the equipment
- Manufacturer recommendations combined with actual hours of use (Correct answer)
- The number of students enrolled in the program
- The cost of the equipment when purchased
Correct answer: Manufacturer recommendations combined with actual hours of use
Manufacturer maintenance schedules combined with actual usage hours provide the most accurate basis for maintenance frequency.
Question 2: A CTE woodworking teacher wants to ensure table saw blades remain in optimal condition. Which practice best achieves this?
- Sharpening blades only when they completely stop cutting
- Regularly cleaning resin buildup and inspecting for missing or damaged teeth (Correct answer)
- Replacing blades every month regardless of condition
- Using the highest feed rate to minimize blade contact time
Correct answer: Regularly cleaning resin buildup and inspecting for missing or damaged teeth
Cleaning resin buildup and inspecting blade teeth maintains cutting efficiency and prevents dangerous blade failure.
Question 3: When documenting preventive maintenance in a CTE program, which information is LEAST important to record?
- Date the maintenance was performed
- Name of the person performing the maintenance
- The original purchase price of the equipment (Correct answer)
- Parts replaced or adjustments made
Correct answer: The original purchase price of the equipment
Purchase price is a financial record, not a maintenance record, and is not relevant to tracking equipment service history.
Question 4: A CTE HVAC instructor is teaching students about filter maintenance in air handling units. What is the correct rationale for regular filter replacement?
- To reduce electricity costs by increasing airflow resistance
- To prevent restricted airflow that overworks the blower motor and reduces air quality (Correct answer)
- To comply with fire codes that require monthly filter changes
- To collect condensation from the evaporator coil
Correct answer: To prevent restricted airflow that overworks the blower motor and reduces air quality
Clogged filters restrict airflow, causing the blower motor to work harder, reducing efficiency, and degrading indoor air quality.
Question 5: In a CTE manufacturing lab, a student reports that a lathe makes a grinding noise when starting. What should the teacher do first?
- Demonstrate proper ear protection and continue the lesson
- Immediately shut down the lathe and tag it out of service for inspection (Correct answer)
- Increase lubrication and see if the noise resolves
- Reduce the lathe speed and monitor for changes
Correct answer: Immediately shut down the lathe and tag it out of service for inspection
Grinding noises indicate potential bearing or gear failure; the equipment must be taken out of service for inspection before use continues.
Question 6: Which type of preventive maintenance task is considered a 'Level 1' or operator-level task in most CTE shop settings?
- Replacing electric motor bearings
- Rewiring control panels
- Cleaning, lubricating, and visually inspecting equipment before use (Correct answer)
- Overhauling gearboxes and transmission systems
Correct answer: Cleaning, lubricating, and visually inspecting equipment before use
Operator-level maintenance includes cleaning, basic lubrication, and visual inspection — tasks that can be performed by trained users.
Question 7: A CTE teacher is building a preventive maintenance program from scratch. What should be the FIRST step?
- Purchase all replacement parts in advance
- Create an equipment inventory with manufacturer maintenance specifications (Correct answer)
- Train students to perform all maintenance tasks
- Hire a full-time maintenance technician
Correct answer: Create an equipment inventory with manufacturer maintenance specifications
An accurate equipment inventory paired with manufacturer specs forms the foundation of any effective preventive maintenance program.
