Fendt 900 Vario S4 service schedule

1. Park on level ground, lower the linkage and any implement, stop the engine, take the key out and chock the wheels.
2. Do a stationary regeneration of the particulate filter first (the dealer says it must be done before changing the oil), then let the engine cool a little. Let it stand a few minutes. Hot oil burns, and the exhaust is very hot after a regeneration. Wear gloves.
3. Remove the sump drain plug and let the oil drain fully.
4. Remove the old oil filter and clean the filter seat. Wipe a little clean oil on the new seal and fit it as the filter says.
5. Fit the drain plug with a new gasket and tighten it to the torque in your handbook.
6. Fill with the oil, run the engine for a minute, stop, wait a few minutes and check the dipstick. Top up to the mark, not above.
7. Check for leaks at the filter and plug. Reset the service reminder on the terminal if your tractor has one.
