Hi Peter, ive got the same one too. As Joe said, enginewise same as a mower. Just check the bearing in the front housing behind the blade is not sloppy because it will eventually flog out the housing and check the belt is not too loose, you cant actually tighten the belt as it has a preloaded spring applying the tension but make sure the belt is not stretched and loose as it will slip a lot if the blade gets onto some light resistance(theyre designed to slip[ so you dont bend stuff),
Good luck with it!
