Recommended Maintenance for Engine Air Filter: To ensure optimal performance, it is advisable to clean or replace your engine air filter approximately every 50 operating hours. In dry and dusty environments, more frequent attention is recommended. The instructional video and guidelines provided below offer a comprehensive walkthrough to assist you in either cleaning or replacing your air filter.

Step 1: Begin by placing your Ultima zero-turn mower on a level and even surface. Ensure that the engine is turned off and has cooled down. Safely remove the ignition key, disconnect the spark plug ignition wire, and engage the parking brake. These precautions prevent accidental starting and potential harm to you and those nearby.

Step 2: Thoroughly clean the engine to remove any accumulated dirt and debris. This step helps maintain a clean workspace during the maintenance process.

Step 3: Release the lock handles securing the air filter cover in place.

Step 4: Carefully remove the air filter from its housing.

Step 5: Examine the air filter for any signs of damage or tears, especially using a flashlight to assess the paper element filter. Gently tap the paper element filter to dislodge dust and debris. In cases of heavy dirt accumulation or damage, it’s advisable to replace the air filter with a new one.

Step 6: Thoroughly wash the foam pre filter using mild detergent and warm water. Allow the foam pre filter to air-dry completely. Note: Please avoid using gasoline or low flash-point solvents for cleaning the air filter components.

Step 7: Once the foam pre filter is completely dry, carefully place it back onto the air filter.

Step 8: Gently place the air filter back into its housing, ensuring a secure fit.

Step 9: Reposition the air filter cover and lock handles to securely fasten it in place.

Step 10: Securely reconnect the spark plug ignition wires.

By following these steps, you can effectively maintain your Ultima zero-turn mower’s engine air filter, ensuring its longevity and peak performance. For model-specific nuances, always refer to your operator’s manual.
