A rattling noise in the drive shaft pipe of an Echo PAS-225, when the engine is working but the string head is not spinning, could be caused by the inner drive shaft not engaging properly with the square upper drive shaft socket. This may happen if the attachment is not fitted correctly into the coupler or if the inner drive shaft is damaged or disconnected.
