During the daily pre-operation check, a loader operator identifies a loose lug nut on one of the wheel assemblies. The loader is otherwise ready for operation and is needed for a critical job. What is the correct procedure for the operator to take?

Question: During the daily pre-operation check, a loader operator identifies a loose lug nut on one of the wheel assemblies. The loader is otherwise ready for operation and is needed for a critical job. What is the correct procedure for the operator to take?

Answer options: ✅ Tighten the loose lug nut immediately using an appropriate torque wrench and re-check all other lug nuts on that wheel.

• Apply a temporary weld to the lug nut to secure it until the end of the shift.
• Label the wheel as 'defective' and continue operating with caution.
• Inform the supervisor and wait for a mechanic to address the issue before operation.

Correct answer: Tighten the loose lug nut immediately using an appropriate torque wrench and re-check all other lug nuts on that wheel.

Explanation: Loose lug nuts are a critical safety concern that can lead to wheel detachment. The operator, if trained and equipped, should tighten it immediately to the specified torque and check others on that wheel as part of pre-operation checks. Welding is unsafe and unnecessary, operating with a known defect is dangerous, and waiting for a mechanic for a simple, immediate fix wastes time and poses a risk.
