make sure you are not connected to the power, the blades are bolted together. undo those and use macine light oil lubrication to all surfaecs of the facing baldes. bolt back together and try again, if the trimmer ddoes not run freely, you will need to strip down the motor housing. If after this moderate servicing the trimmer does not work freelyy, there is a problem from the electic motor, which could mean the gearing is siezed, which is another problem altogether!
