hi adam so you ve had the same problem as me with your chain keep coming off....its really started to annoy me now!

came off 3 times today...phoned PF up and asked could i adjust the tension(which you do by loosening the 4 nuts on the motor)if this doesnt work then its going back...

how much give have you got on the chain?too tight and it doesnt run smoothly,too loose and it comes off....

also the reel makes a knocking noise after every revolution whether im reeling in or pulling hose off ,pure freedom says this is normal,some reels do it and some dont,they said they dont know the reason why.the spindle seems slightly warped to me as the inlet side with the rotary joint is a bit uneven when turning(its the same on my cox reel so this is normal i think)....
im sick to death of faffing about with it now....TBH i wish id gone for the grippatank geared reel instead........
