An operator performing a pre-shift inspection notices that the hydraulic oil level in the sight glass is below the 'add' mark. The loader is parked on level ground, and the engine has been off for an hour. What is the most appropriate action?

Question: An operator performing a pre-shift inspection notices that the hydraulic oil level in the sight glass is below the 'add' mark. The loader is parked on level ground, and the engine has been off for an hour. What is the most appropriate action?

Answer options: ✅ Add hydraulic fluid until it reaches the 'full' mark and document the addition.

• Operate the loader for a short period to allow the fluid to warm up, then re-check the level.
• Notify the supervisor immediately as this indicates a serious hydraulic system leak.
• Continue operations and monitor the hydraulic pressure gauge for abnormalities.

Correct answer: Add hydraulic fluid until it reaches the 'full' mark and document the addition.

Explanation: If the hydraulic oil level is below the 'add' mark when cold and on level ground, it indicates a low fluid level that needs replenishment. Documenting the addition helps track fluid consumption and potential leaks. Operating the machine before topping off could cause damage.
