A blocked air filter could result in reduced engine performance, more difficult starts, and a higher amount of fuel consumed. This guide will take you through the process step-by-step and will cover the tools required as well as maintenance schedules and the advantages of regular air filter replacements.

A proper maintenance routine can increase the lifespan that you get from your miniature excavator and help keep it running efficiently, particularly in areas that are dusty.

Why Change the Engine Air Filter Regularly?

A filter in the air plays an important part in maintaining the engine of your mini excavator operating properly and clean. If the air filter has become blocked by dust and dirt, this can lead to a variety of problems:

Lower engine power A filthy air filter blocks airflow, which can affect the performance of your engine.
hard starts When the engine isn't receiving sufficient fresh air, it may cause more difficulty in starting.
Higher fuel consumption The result of a blockage in the filter causes an engine to perform harder and consume more fuel.
Engine Damage In time, debris and dirt could get into the engine, leading to damage and wear.

To avoid problems like this It is essential to wash and replace your filter every 100 hours andchange it every 400 hours or more often in conditions that are dusty.
