NSC Maintenance & Inspection Procedures 2 — Questions and Answers
Question 1: When should the hydraulic fluid level on a forklift be checked?
- Only after a hydraulic leak is noticed
- Before each shift as part of the pre-shift inspection (Correct answer)
- Every 250 hours of operation only
- After every 10 loads lifted
Correct answer: Before each shift as part of the pre-shift inspection
Hydraulic fluid level must be checked before each shift during the pre-shift inspection to ensure safe lifting operation.
Question 2: A forklift operator notices the mast chains are dry and show visible rust. What is the correct action?
- Continue operating until the next scheduled service
- Apply chain lubricant immediately and tag the unit for maintenance (Correct answer)
- Operate at reduced speeds only
- Report the issue at the end of the week
Correct answer: Apply chain lubricant immediately and tag the unit for maintenance
Rusty, dry mast chains are a safety hazard and must be lubricated and the unit flagged for maintenance before continued use.
Question 3: Which component should be inspected for cracks, bends, or excessive wear during a forklift pre-shift check?
- The seat belt buckle only
- The forks (Correct answer)
- The backup alarm cover
- The operator's manual holder
Correct answer: The forks
Forks must be inspected for cracks, bends, and wear because damaged forks can fail under load and cause serious injuries.
Question 4: What does a red tag placed on a forklift indicate?
- The forklift is fueled and ready for use
- The forklift is out of service and must not be operated (Correct answer)
- The forklift requires an oil change within 50 hours
- The forklift is assigned to a specific operator
Correct answer: The forklift is out of service and must not be operated
A red tag is used to indicate that equipment is out of service and must not be operated until repaired and cleared.
Question 5: During inspection, the operator finds that the forklift's overhead guard has a cracked weld. What should happen next?
- Operate carefully at low speeds and report it at shift end
- Remove the overhead guard and continue working
- Remove the forklift from service immediately and report the damage (Correct answer)
- Weld the crack personally if tools are available
Correct answer: Remove the forklift from service immediately and report the damage
A cracked overhead guard compromises operator protection from falling objects and requires immediate removal from service.
Question 6: How often should forklift tires be inspected for cuts, chunking, or pressure issues?
- Once a month
- Only when a flat tire is suspected
- Before each shift (Correct answer)
- Every 500 hours of operation
Correct answer: Before each shift
Tire condition should be checked before every shift because tire failure can cause loss of stability and tip-overs.
Question 7: Which of the following is a sign that a forklift's brake system needs maintenance?
- The brakes engage smoothly and stop the truck within normal distance
- The forklift pulls to one side or requires excessive pedal pressure to stop (Correct answer)
- The brake warning light is green
- The brakes squeak only when reversing
Correct answer: The forklift pulls to one side or requires excessive pedal pressure to stop
Pulling to one side or requiring excessive pedal pressure indicates uneven brake wear or a hydraulic issue requiring immediate maintenance.
