Common Maintenance Practices for the Kobelco SK-200LC-2
Regular maintenance is essential to keep the Kobelco SK-200LC-2 running smoothly and efficiently. Failure to follow maintenance guidelines can lead to costly repairs and reduced machine longevity. Below are some key maintenance practices to consider:
- Engine Oil and Filter Replacement:
The engine oil should be replaced regularly according to the manufacturer’s recommendations. Changing the oil and oil filters at the prescribed intervals helps to prevent engine wear and maintain optimal performance. Always use the recommended oil type to avoid damage to the engine.
- Hydraulic Fluid and Filter Changes:
The hydraulic system plays a crucial role in the machine’s performance, so it’s essential to maintain clean hydraulic fluid and regularly change the hydraulic filters. Contaminants in the hydraulic system can cause poor performance and premature wear. The manual will provide guidelines on the correct fluid type and the frequency of changes.
- Inspect and Maintain Tracks:
The undercarriage is one of the most critical components of the excavator. Regularly inspecting the tracks, rollers, and sprockets will help identify wear and damage. Track adjustments should be made periodically to ensure proper tension, as loose or overly tight tracks can cause excessive wear and reduce machine stability.
- Coolant System Maintenance:
Regularly check the coolant levels and condition to prevent engine overheating. The cooling system should be flushed and refilled at recommended intervals to maintain the engine at optimal operating temperatures.
- Air Filter Inspection:
The air filter plays a crucial role in preventing dirt and debris from entering the engine. It should be inspected and cleaned or replaced regularly to ensure the engine receives clean air, preventing potential damage and maintaining fuel efficiency.

Low Hydraulic Power
If you notice sluggish operation or a lack of hydraulic power in the excavator, there may be several underlying causes:
- Hydraulic Fluid Low or Contaminated: Low or contaminated fluid can reduce the hydraulic pressure, resulting in weak performance. Check the fluid level and condition regularly.
- Damaged Hydraulic Pump or Valve Block: If the hydraulic pump is damaged or malfunctioning, it may not produce the necessary pressure. Inspect the pump and valve block for leaks or signs of wear and replace any damaged components.
- Clogged Filters: A clogged hydraulic filter can restrict fluid flow, reducing the system’s efficiency. Always replace filters at the recommended intervals.
If the engine stalls or runs roughly, consider the following checks:
- Fuel System Issues: Dirty or clogged fuel injectors or a blocked fuel filter can lead to poor engine performance. Inspect and clean the fuel system components as needed.
- Air Intake Blockages: A blocked air intake or dirty air filter can cause the engine to stall. Check and clean or replace the air filter to ensure proper airflow.
- Low or Dirty Oil: Low or dirty engine oil can lead to stalling and rough running. Regular oil changes are essential to prevent these issues.
Electrical failures can lead to various operational issues. Some common problems include:
- Dead Battery: A weak or dead battery may prevent the engine from starting. Check the battery voltage and replace it if necessary.
- Fuses and Relays: If certain electrical systems are malfunctioning, it’s worth inspecting fuses and relays. Replace any blown fuses and test the relays to ensure proper operation.
To get the most out of your Kobelco SK-200LC-2, following a few simple yet effective practices can help extend the machine’s lifespan:
