I realise it's a long time since you asked the question, but in case anyone else wants to know how to change the belts, use the tensioner to SLACKEN the belts right off (wind it the other way). Then (wearing protective gloves) pull the outer belt off the pulley, while gently turning the pulleys to help it. It's not easy, and you must take care not to pinch your fingers etc. Repeat the procedure with the inner pulley, and then reverse the process to put the new belts on.
Good day! I have the same mower at120, and quite often the drive belts break (works 3 hours). How many hours do your belts work? and how do you change them?
I've had the same issue, but the problem was that the pulleys were not aligned. After we align bottom pulley with top pulley, it works perfectly. It took me 6 belts to resolve this issue :/
DON'T BUY KELLFRI !!!!!! Their products are not real, rather toys like the real machines. I bought one and it worked just several hours and Kellfri wouldn't take responsibility for the warranty. And practically there is NOT any authority that take your complaint as serious. So it's easier to throw away the toy.
