Fendt 724 Vario Gen6 service schedule

1. Run a stationary DPF regeneration from the terminal first, as the dealer schedule says, and let it finish.
2. Park on level ground, lower the linkage, loader and any implement to the ground, stop the engine, take the key out and chock the wheels.
3. Let it stand a few minutes. Hot oil burns, and the exhaust and DPF are very hot after a regeneration. Wear gloves.
4. Remove the sump drain plug and let the oil drain fully.
5. Remove the oil filter, check the old seal came off, and wipe the filter head clean.
6. Oil the new filter seal and fit it hand-tight.
7. Fit a new gasket to the drain plug, refit it and fill with 10W-40 to the full mark.
8. Run the engine for a minute, check for leaks, stop it and recheck the level.

Tools: Drain tray (25 L), Filter wrench, Spanner for sump plug, Funnel, Rags, Gloves
