5. Operate the Fuel System: If the fuel system is stopped, follow the procedures to get it up and running again. This ensures a consistent fuel supply.
6. Valve Position: Change the position of valves from “stop” to the “operating” position to allow fuel flow.
7. Leakage Check: Examine the entire fuel system for any signs of leakage. If you find any leaks, take immediate corrective action to prevent fuel wastage and potential hazards.
8. Air Venting: Check the system for proper air venting. Adequate venting ensures that fuel flows smoothly without airlocks.

Preparation of Lubricating Oil System

Before starting the engine, it’s essential to ensure that the lubricating oil system is in good shape. Here’s a step-by-step guide:

1. Check Sample Date: Verify when the last oil sample for quality check was taken. Regular oil quality checks are crucial for engine health.
2. Replace Oil Filters: If the engine has been overhauled or idle for an extended period, replace the oil filters to maintain optimal oil quality.
3. Oil Sump Tank Level: Check the oil level in the sump tank. If it’s low, top it up to the required level.
4. Valve Position: Change the position of the valve to the “operational” setting. This allows the lubricating oil to flow as needed.

Pre-lubrication of the Engine

Before starting the engine, perform pre-lubrication to ensure proper oil flow and engine health:

1. Heat Oil Temperature: A heater raises the lubricating oil temperature to 40⁰C. Proper oil temperature is essential for engine performance.
2. Lubricating Oil Pump: If the lubricating oil pump was stopped, operate it to ensure oil circulation.
3. Check for Leaks: Inspect the system for any oil leaks and address them promptly to prevent wastage and maintain oil levels.
4. Oil Pressure and Condition: Monitor oil pressure and the condition of the pre-lubricating oil to ensure it meets engine requirements.

Pre-Lubrication Timing: Perform pre-lubrication at least 5 to 10 minutes before starting the engine. This is particularly important if the engine has been idle for an extended period or has undergone an overhaul.

Ensure Oil Flow: Confirm that oil flows smoothly from key points, including bearings, pump and valve operating rollers, and remove any maintenance tapes that may have been applied.

By following these steps, you’ll ensure that the lubricating oil system is ready for action, promoting the efficient and reliable operation of the engine.

Intake Air and Exhaust System Preparation

Before starting the engine, it’s vital to prepare the intake air and exhaust system. Here’s a step-by-step guide:
