To check the hydraulic fluid level on an LS Tractor MT122:

1. Stop the engine.
2. Place all transmission gears in neutral.
3. Lower all implements to the ground.
4. Clean around the oil filling port to prevent contamination.
5. Open the cap of the oil filling port.
6. Use the oil gauge: turn it counter-clockwise and pull it up.
7. Check if the oil level is between the MAX and MIN marks on the gauge.
8. If needed, add new oil and wait 5–10 minutes.
9. Recheck the oil level.

Use the correct oil specification as listed in section 5-3 or the last page of the manual.
