Read the manual, do a search. There's plenty of answers to this question on here. It's very simple, drain the crank case (oil plug in middle), drain the oil bottle, replace the filter, add 2000ml of oil and check the dipstick. I'd run it for a minute, let it sit for 3 minutes, then check the oil level.
