Why Change the Engine Air Filter Regularly?
The air filter plays a crucial role in keeping your mini excavator’s engine clean and functioning properly. If the air filter is clogged with dust and debris, it can cause several issues:
- Reduced Engine Power: A dirty air filter restricts airflow, which affects engine performance.
- Hard Starts: If the engine isn't getting enough clean air, it can make starting more difficult.
- Increased Fuel Consumption: A clogged filter forces the engine to work harder, consuming more fuel.
- Potential Engine Damage: Over time, dirt and debris can enter the engine, causing wear and tear.
To prevent these issues, it’s essential to clean your air filter every 100 hours of operation and replace it every 400 hours, or more frequently in dusty conditions.
What Tools and Materials Do You Need?
Before getting started, make sure you have the following:
- A New Air Filter: You can contact AHM customer service to purchase from us separately.
- Basic Tools: No special tools are needed for this job; you may only need your hands to turn or push locks, depending on your mini excavator model.
