yes its a slipped belt or broken belt its a complete strip down of the machine you need to take off the blade from underneath then the impeller that the blade is attached to you will see screws undo the screws about 9 turn the machine upright remove the 2 screws holding the orange nose piece lift off the cover pulling it forward you will see the motor the screws you undid before will have released the motor housing lift the whole housing out, to fit new belt try putting the belt on over the two pulleys if the belt is slack undo the 4 screws holding the motor slide the motor fasten the screws up try the belt again until you get the right tension spin it by hand to make sure it it does not slip off the smooth pulley if ok reassemble 9 screws underneath first then orange nose piece last
