1. Wash the foam element in liquid soap and warm water, and rinse it thoroughly.

2. Dry the element by squeezing it in a clean cloth.

3. Saturate the element in engine oil.

4. Squeeze the element in a clean, absorbent cloth to remove the excess oil.

Important: Replace the foam element if it is torn or worn.

Paper Element

1. Lightly tap the paper element on a flat surface to remove dust and dirt.

2. Inspect the element for tears, an oily film, and damage to the rubber seal.

Important: Never clean the paper element with pressurized air or liquids such as solvents, gasoline, or kerosene. Replace the paper element if it is damaged or cannot be cleaned thoroughly.

Installing the Foam and Paper Elements

Important: To prevent engine damage, always operate the engine with the complete foam and paper air cleaner assembly installed.

1. Install the foam element with the mesh side up.

Note: Ensure that the rubber seal is flat against the air cleaner base.

2. Position the paper element on the foam element in the air cleaner base.

Checking the Engine Oil Level

Service Interval: Before each use or daily

1. Park the machine on a level surface.

2. Disengage the blades (PTO).

3. Set the parking brake.

4. Stop the engine and wait for all moving parts to stop.

5. Remove the ignition key.

6. Open the hood.

7. Clean around the dipstick (Figure 25 ) so that dirt

cannot fall into the filler hole and damage the engine.

12. Stop the engine and wait for 30 seconds.

13. Check the oil level again and add oil if necessary.

Important: Do not overfill the crankcase with engine oil and run the engine; engine damage may result.

Changing the Engine Oil

Service Interval: After the first 5 hours

Every 50 hours (Change the engine oil more frequently when operating the machine in extremely dusty or sandy conditions.)

1. Start the engine and let it run for 5 minutes.

Note: This warms the oil so that it drains better.

2. Park the machine so that the drain side is slightly lower than the other side to ensure that the oil drains completely.

3. Disengage the blades (PTO).

4. Set the parking brake.

5. Stop the engine and wait for all moving parts to stop.

6. Remove the ignition key.

7. Open the hood.

8. Place a pan below the oil drain plug.

Full mark on the dipstick.

11. Start the engine and let it idle for 30 seconds.

10. When oil has drained completely, insert the drain plug and tighten it securely.

Note: Note: Recycle the used engine oil properly.

11. Clean around the dipstick and unscrew the cap

(Figure 25).

12. Slowly pour approximately 80% of the engine oil

into the filler tube (Figure 25). Refer to Servicing

the Engine Oil.

13. Check the engine oil level; refer to Checking the
