Question: During routine preventive maintenance, a telehandler operator discovers that the engine air filter restriction indicator on the dashboard is illuminated. What is the most appropriate action to take?

Answer options: ✅ Schedule the replacement of the engine air filter as soon as possible.

• Bypass the air filter to reduce restriction until a new one can be installed.
• Clean the existing air filter with compressed air and reinstall it.
• Ignore the indicator, as it will likely reset after some engine operation.

Correct answer: Schedule the replacement of the engine air filter as soon as possible.

Explanation: An illuminated air filter restriction indicator means the filter is clogged and needs replacement to ensure proper engine performance and prevent damage. Cleaning the filter with compressed air can damage the filter media, while bypassing it allows contaminants into the engine, both leading to severe engine wear. Ignoring the indicator will result in reduced engine efficiency and potential damage.
