I am renting the above and have just assembled the trolley.however,the bits I have left over are plentiful and there are no instructions on where to put them all.have an 8mm hose (100m) and loads of connectors.I've tried to google it and no luck.

any help would be appreciated.
just starting out as you've probably guessed.
also,when I get to practice on it,can I use ordinary tap water,then pump purified through to clean it when I do paid work ?
