Just brought a Gerni 2750 vax from Ebay. Very powerful twin motors etc supplied with 50mm hose.
Went to use on my own house today on lower level gutters and its so powerful its sucking everything up and in 20 minutes it got blocked 3 times ! That was just using the hose. I even turned one motor off to reduce power
Any advice what I should or shouldnt be doing ?
Thanks
