It looks to me like the Stiga isn't sold in the USA. Maybe if you go to a Stiga parts dealer he will have a service manual he can sell you. When I get a peace of equment in my shop I am not familiar with and can't find a manual on line I tell the customer that a repair manual will be on his bill. It will be a very usefull tool to have with your Stiga if you plan on your own repairs in the future.
