Takeaways

• 😀 Ensure that all team members are informed about the work and safety procedures before starting the maintenance task.
• 😀 Always confirm that safety protocols, such as logout and lockout, are properly implemented to isolate hazardous energy in the unit.
• 😀 Prepare the necessary tools and equipment before starting the service, including checking that the safety equipment is ready.
• 😀 Conduct thorough checks on battery areas, ensuring the vent blocks are clean, battery levels are standard, and connections are free of corrosion.
• 😀 When replacing filters, ensure proper sealing with oil and tightening using the correct tools, then check for leaks.
• 😀 Inspect all unit parts such as the Thailand Jin filter and alternators for any dirt or damage, and clean or replace as necessary.
• 😀 Regularly monitor the oil levels in the engine, ensuring it’s filled to the correct levels, using the specified oil grade (15W-40).
• 😀 During inspections, clean and replace air filters, ensuring they meet the maintenance threshold of five cleanings before replacement.
• 😀 Always ensure the cooling system and connections are properly inspected for leaks or wear, with particular attention to seals and gaskets.
• 😀 For final drive checks, monitor the condition of the tracks and perform measurements using either manual or ultrasonic tools to ensure proper functionality.

Q & A

What is the first step in preparing for the maintenance process?

The first step is ensuring that the work permit (Jesa) has been created and socialized with the team. It is also important to make sure the logout and tag-out procedures are correctly applied to isolate any hazardous energy in the unit.

What tools are necessary for the maintenance work described in the video?

The required tools include a toolbox, safety equipment, special tools for checking undercarriage parts, and a few specific tools such as the V2U and an ultrasonic tool for measurements.

How should the battery vent block be checked during the maintenance?

The battery vent block should be checked to ensure it is clean and free from obstructions. The electrolyte level should be at standard levels, and the fairing should be in good condition, without any rust.

What is the procedure for replacing a filter during the maintenance process?

After removing the old filter, the area should be cleaned to remove any dirt or debris. Before installing the new filter, apply oil to the gasket to ensure a proper seal. Tighten the filter with your hand, and then give it an additional 3/4 turn with a tool.

What should be done when inspecting the engine oil level during maintenance?

When checking the engine oil, ensure the level is between the 'Low' and 'High' marks. After replacing the oil, make sure the refill amount is correct, which is approximately 24 liters, and use the recommended oil type, which is ESSAY 15W 40.

How should the water separator be cleaned?

The water separator should be cleaned by first removing the cover. If the cover is dirty, it should be washed and dried before being reinstalled.

What is the procedure for checking the air intake system?

Inspect the intake system, including the turbo and connections, for any issues. Check the condition of the cooling system and verify that all connections are secure.

What is the importance of checking the air cleaner during the maintenance process?

The air cleaner should be checked regularly and cleaned up to five times. After the fifth cleaning, the inner and outer air cleaner elements must be replaced.

How should the final drive system be inspected during maintenance?

The final drive system should be checked to ensure the track's condition is correct. If the level is low, it should be topped up, and the system should be inspected for any abnormal wear or damage.

What safety precautions should be taken when performing maintenance tasks with potential hazards?

When performing tasks that involve internal pressure, like loosening bolts or checking track tension, it is critical to avoid loosening more than one turn to release pressure. Keep a safe distance from any areas that could eject fluids or debris, and always wear proper protective equipment.
