I bought a GPS520 petrol brush cutter. It worked well last Summer when I first used it, but this Spring it would not start. All of the fuel lines were perished and broken, the carburettor components were totally perished also. Pretty bad for this to happen within one year. The fuel components were clearly not E10 fuel compliant and totally unsuitable. SGS were of no help so I purchased a replacement carburettor and fuel line from my local garden equipment service centre and the motor runs well again. I would not entertain buying any other items from this Company as their quality control is abysmal. Very poor service.
