I am a new teg owner..

and my teg hit 30k and needs a tune-up.

what is the difference of minor tune-up @ every 7,500 miles verses major tune-up @ every 30,000 miles?

if I get the major tune-up, do I still need to do the minor tune-up every 7,500?

would the service repair manual give info on how to do all these self-services?


thanks
