AG Mechanics CDE Practice Exam

The recommended cleaning interval for a single element air cleaner for small engines is every:

1. 10 hours of operation

2. 15 hours of operation

3. 20 hours of operation

4. 25 hours of operation

The correct answer is: 10 hours of operation

The correct answer is A, 10 hours of operation. It is recommended to clean a single element air cleaner for small engines every 10 hours of operation to ensure that the engine receives a consistent flow of clean air. Regular cleaning helps prevent dirt and debris from clogging the filter, which can negatively impact engine performance. The other options (B, C, and D) suggest longer intervals between cleanings, which may result in a buildup of contaminants that could decrease the efficiency of the air filter and, consequently, the engine's performance.
