Ordered a ranger 6/500 from machine mart. Soon as plugging in the the valve blew it wouldn't turn off .so they sent another out and was on building up pressure then the tap blew off.the 3rd one they sent out was bent up on wheel frame plastic broke and wouldn't switch off .the engineer told me if I didn't mind bending the chassis back to take the cover off and adjust a screw for it to switch off but wasn't gonna do that it was mentioned to be new and in working order so asked for refund but no explanation or apology .will not be going there again. Wolverhampton especially
