CTE Preventive Maintenance Procedures 2 — Questions and Answers
Question 1: In a CTE shop setting, what is the PRIMARY purpose of a lubrication schedule for equipment?
- To reduce friction and prevent premature wear on moving parts (Correct answer)
- To clean debris from machine surfaces
- To calibrate measurement tools
- To document equipment purchase dates
Correct answer: To reduce friction and prevent premature wear on moving parts
Lubrication schedules reduce friction between moving parts, extending equipment life and preventing costly breakdowns.
Question 2: A CTE automotive teacher notices coolant levels dropping regularly without visible leaks. What preventive maintenance step should be taken first?
- Replace the entire cooling system immediately
- Perform a pressure test on the cooling system to locate slow leaks (Correct answer)
- Add more coolant and continue normal operations
- Flush the radiator and refill with fresh coolant
Correct answer: Perform a pressure test on the cooling system to locate slow leaks
A pressure test identifies slow or internal leaks that are not visible externally, allowing targeted repairs.
Question 3: Which maintenance record should a CTE teacher maintain to demonstrate compliance with OSHA equipment safety standards?
- Student attendance logs
- Equipment inspection and maintenance logs with dates and technician signatures (Correct answer)
- Budget spreadsheets for supply purchases
- Curriculum alignment documents
Correct answer: Equipment inspection and maintenance logs with dates and technician signatures
Signed, dated maintenance logs demonstrate due diligence and compliance with OSHA equipment safety requirements.
Question 4: When should drive belts on CTE shop machinery be inspected for replacement?
- Only after the belt breaks during operation
- During scheduled preventive maintenance intervals and when signs of cracking or fraying appear (Correct answer)
- Once every five years regardless of use
- Only when the machine produces unusual sounds
Correct answer: During scheduled preventive maintenance intervals and when signs of cracking or fraying appear
Drive belts should be inspected on a scheduled basis and whenever visual signs of wear like cracking or fraying are present.
Question 5: A welding instructor notices the MIG welder's wire feed is inconsistent. Which preventive maintenance action addresses this issue?
- Replace the welding wire with a thicker gauge
- Clean the wire feed rollers and liner, and check drive roll tension (Correct answer)
- Increase the voltage settings on the welder
- Replace the ground clamp cable
Correct answer: Clean the wire feed rollers and liner, and check drive roll tension
Dirty feed rollers and an obstructed liner are common causes of inconsistent wire feed in MIG welders.
Question 6: What is the safest approach when a CTE teacher discovers a small hydraulic fluid leak on a shop press during a routine inspection?
- Place a drip pan under the press and continue student use until the leak worsens
- Tag the equipment out of service, clean the leak, and repair before returning to use (Correct answer)
- Tighten all fittings while the press is under full hydraulic pressure
- Add hydraulic fluid daily to compensate for the loss
Correct answer: Tag the equipment out of service, clean the leak, and repair before returning to use
Equipment with hydraulic leaks must be taken out of service and repaired before use to prevent safety hazards and equipment damage.
Question 7: In a CTE electrical program, how often should portable power tools be inspected for cord and plug integrity?
- Annually during summer break only
- Before each use and during scheduled maintenance intervals (Correct answer)
- Only after a student reports a problem
- Every two years per manufacturer warranty cycles
Correct answer: Before each use and during scheduled maintenance intervals
Portable power tools should be visually inspected before each use and during regular maintenance to prevent electrical hazards.
