Requires oil change after 8 hrs run time and full tune up every 200hrs of run time with oil change and spark plug. Also system does 7 min self check every week have to add that time into total run time.
Oil change after 8 hours run time is a rather misleading statement. Where are you getting your number from?
Oil change, filter replace after 200 hours run time or 2 years whichever comes first.
Fires up and runs for 7 min once a week is roughly 6 hours per year so not exactly adding a lot of hours to the engine.
