That info is in your owners manual, which you can DL from

Oil changes should be every 50 hours or annually, whichever comes first.
You need NMMA type FC-W, SAE 10w-30. It holds about 1L. DO NOT overfill. The oil level on the dipstick should be at or a little below the full mark; not even a drop above. When refilling, it will take significant time for the oil to read on the stick, so again, don't overfill.
