WALMART MAINTENANCE Equipment Troubleshooting 5 — Questions and Answers
Question 1: A forklift's load backrest extension is cracked. The correct action before returning the unit to service is:
- Replace the backrest extension before use (Correct answer)
- Weld the crack and inspect weld quality
- Tape the crack and monitor it
- Reduce load size to compensate
Correct answer: Replace the backrest extension before use
A cracked load backrest extension must be replaced; structural cracks compromise the safety function of the component.
Question 2: An HVAC unit in the store makes a loud banging noise only at startup. After the first few seconds, it runs quietly. This pattern suggests:
- Loose or failed motor mount allowing startup torque shock (Correct answer)
- Refrigerant overcharge
- Dirty air filters
- Faulty thermostat setpoint
Correct answer: Loose or failed motor mount allowing startup torque shock
A loose or broken motor mount allows the motor to shift violently during startup torque, then settles during steady-state operation.
Question 3: A battery-operated floor sweeper has reduced runtime per charge compared to when it was new. The maintenance technician should:
- Test battery capacity and replace worn battery cells or pack (Correct answer)
- Run the sweeper at lower speed only
- Recharge more frequently without investigating
- Replace the main brush motor
Correct answer: Test battery capacity and replace worn battery cells or pack
Reduced runtime is the primary symptom of battery capacity degradation; testing and replacing the battery pack restores normal operation.
Question 4: A dock seal or dock shelter is torn and allows outside air and rain into the facility. The immediate safety concern is:
- Slippery wet floor creating slip and fall hazard (Correct answer)
- Damage to the dock leveler
- Loss of wi-fi signal near the dock
- Increased forklift fuel consumption
Correct answer: Slippery wet floor creating slip and fall hazard
Water intrusion from a damaged dock seal creates wet floor conditions that are a direct slip-and-fall hazard for associates.
Question 5: A propane forklift starts but runs roughly and lacks power. The LPG tank gauge reads full. What should be inspected?
- Vaporizer/regulator and fuel filter for ice or restriction (Correct answer)
- Tire tread depth
- Mast chain elongation
- Seat belt latch
Correct answer: Vaporizer/regulator and fuel filter for ice or restriction
A full tank with poor engine performance points to a restricted vaporizer, iced regulator, or clogged fuel filter preventing proper fuel delivery.
Question 6: After a power outage, a refrigerated meat case restarts but displays a high-temperature alarm. The correct first response is:
- Monitor and log the temperature, and notify the department manager while the case pulls down (Correct answer)
- Discard all product immediately
- Disable the alarm sensor
- Move product to a warmer display
Correct answer: Monitor and log the temperature, and notify the department manager while the case pulls down
After a power outage a case needs time to pull down to set point; monitor and log temperatures while following store food safety protocols.
Question 7: A manual hand truck has a bent axle causing one wheel to wobble during use. The safest action is:
- Remove from service and tag out until the axle is replaced (Correct answer)
- Use the hand truck only for light loads
- Bend the axle back with a pipe and continue use
- Duct-tape the wheel and report it at end of shift
Correct answer: Remove from service and tag out until the axle is replaced
A bent axle creates an unpredictable wheel failure risk; the hand truck must be tagged out and repaired before returning to service.
