the oil more frequently if the engine has
to operate in demanding conditions.
Proceed as follows:
1. Place the machine on a flat surface.
2. Place a suitable container
under the drain plug.
3. Remove the top-up cap (fig. 10.H)
4. Remove the drain cap (fig. 10.I)
5. Collect the oil in a suitable vessel.
6. Screw the oil drain plug back in.
7. Clean up any spills.
8. Fill with fresh oil. For the quantity of oil to
use, see the "Technical data table".
9. After filling up the oil, start the engine
and leave it to idle for 30 seconds.
10. Check there are no oil leaks.
11. Stop the engine. Wait 30 seconds and
check the oil level again. If necessary,
also see "check/top-up" (par. 7.3.1).
