Sample Maintenance Skills Assessment Test Questions and Answers
Below are some typical questions you might encounter in a maintenance skills assessment test, along with detailed answers to help you prepare effectively.
Electrical Maintenance Questions
- Question: What is the purpose of a circuit breaker, and how does it differ from a fuse?
- Answer: A circuit breaker is a safety device designed to automatically disconnect electrical power during overloads or short circuits, preventing damage and fires. Unlike a fuse, which contains a metal strip that melts when excessive current flows, a circuit breaker can be reset after tripping without needing replacement, making it more convenient and reusable.
- Question: Describe the steps to safely troubleshoot an electrical motor that is not starting.
- Answer:
- Ensure the power supply is turned off and lockout/tagout procedures are followed.
- Visually inspect for obvious issues such as damaged wiring, burnt components, or loose connections.
- Check the motor starter and overload relay for proper operation.
- Test the supply voltage with a multimeter to confirm power is reaching the motor.
- Inspect the motor windings for continuity and insulation resistance.
- If necessary, replace faulty components and restore power to verify operation.
Mechanical Maintenance Questions
- Question: How do you perform a belt alignment check on a conveyor system?
- Answer:
- Turn off the conveyor and lockout/tagout the power source.
- Visually inspect the belt and pulleys for misalignment.
- Use a straightedge or laser alignment tool to check the belt’s alignment with pulleys.
- Adjust pulley positions or belt tension as needed to ensure the belt runs centrally without wobbling.
- Recheck the alignment after adjustments and restart the system to observe proper operation.
- Question: What are common signs indicating that a bearing needs replacement?
- Answer: Signs include unusual noise such as grinding or squealing, excessive vibration, overheating, visible wear or corrosion, and increased operational temperature. Regular inspections can help identify these issues early to prevent equipment failure.
Preventive and Predictive Maintenance Questions
- Question: What is the primary purpose of vibration analysis in predictive maintenance?
- Answer: Vibration analysis helps detect early signs of equipment imbalance, misalignment, bearing failures, or gear defects. By monitoring vibration patterns, maintenance teams can schedule repairs before catastrophic failures occur, reducing downtime and repair costs.
- Question: List three key components of a preventive maintenance program.
- Answer:
- Regular inspection and cleaning of equipment.
- Lubrication of moving parts at scheduled intervals.
- Replacement of worn components based on manufacturer recommendations or condition monitoring data.
Safety and Compliance Questions
- Question: Explain the lockout/tagout procedure and its importance.
- Answer: Lockout/tagout (LOTO) involves isolating energy sources and applying locks or tags to prevent accidental energization during maintenance or repair work. It ensures personnel safety by eliminating the risk of electrical, hydraulic, or pneumatic hazards, and is a critical part of safety compliance standards.
- Question: What PPE should be worn when performing electrical maintenance?
- Answer: PPE includes insulated gloves, safety glasses or face shields, flame-resistant clothing, and insulated tools. Proper PPE minimizes the risk of electrical shock, arc flash, and other injuries.
