I found my display speed numbers are not going up to the maximum speed well not all the time, I find sometimes the trolley LED numbers stop around 5 and sometimes won’t go all the way up to speed 7 on the display. Please can anyone let me know what they think is wrong ?
Most likely your speed control switch is faulty. This part plugs in to the inside of the handle on the board and is easy replaced. Instructions are available for fitting a new speed dial switch on the support page.
