HiProform 535 - about 6 years old.Belt goes fine until I step on to walk. Then it may go for 30 seconds or so before coming to a halt. Sometimes it will just stop straightaway. Won't start from a standstill if I stand on it.Over the last 2 years I have the problem I have replaced the rear roller and the motor+controller and the upper control panel.When it comes to a halt there is nothing moving - i.e. the motor is not carrying on and slipping on the drive belt or front roller. There is an electronic straining noise as though it's trying to go but can't. I did the test of marking with nail polish and there is no slippage.The belt is greased with silicon grease and at the right tension. I know this because a) I get the correct displacement if I lift it at the sides and b) with less tension the belt just slips.Any thoughts?ThanksMike
Detailed in the description of the question
Your walking deck is worn out and it is causing too much friction on the belt. Replacing the walking deck should take care of the problem.
Thanks for your reply.How does a walking deck wear out? Surely it's just a board, isn't it?Sorry to be a bit thick.Mike
it has a special coating on the board and it wears off.
HiThanks again.It is walking platform related but with the belt as well.Apparently I should not have used silicon-based grease (and certainly not as much as I did) - I had been advised to use silicon-based grease.What happens is that the belt is placing material on the walking platform as its being used. As a consequence it ultimately sticks whenever there is any weight on it.I am going to accept your answer but I just thought I would pass back some feedback. It's not obvious whether I can do that once I have clicked Accept Answer.Anyway, thanks again for your help.
Thanks for the info.
