6. IMPORTANT: Dirt and debris can enter the engine through a damaged filter element:

   • Do not wash paper element.

   • Do not attempt to clean paper element by tapping against another object.

   • Do not use pressurized air to clean element.

   • Replace element only if it is dirty, damaged or the seal is cracked.

   Inspect the foam precleaner (D) (If Equipped) without removing it. If the foam pre cleaner is dirty:

   1. Remove it from the filter carefully.

   2. Wash precleaner in a solution of warm water and liquid detergent.

   3. NOTE: Do not put engine oil on pre cleaner. Engine oil may wick into the paper filter element and result in poor engine performance.

      Rinse precleaner thoroughly. Squeeze out excess water in a dry cloth until pre cleaner is dry.

   4. Replace the precleaner if damaged or missing.

7. Inspect paper filter element. Replace the filter element if damaged or dirty.

8. Clean air cleaner base carefully. Prevent any dirt from falling into carburetor or air intake tube.

9. Install foam precleaner (D) mesh side up on paper filter element. Position air filter in air filter base:

   • Model Z425 install cartridge. Make sure that cartridge and seal are properly seated and sealing the carburetor air intake area.
   • Models Z435, Z625, Z445, Z465, Z625, Z645, Z655, and Z665, install also on air intake tube (E). Align air filter clamp on intake tube groove and tighten clamp by turning thumbscrew clockwise until secure.
