Push the corresponding white knob across slowly and pull the thread that appears on the other side slowly until the shorter end appears, and the needle is threaded.Blue plastic rectangle with two insert tubes and two white push tabs, a leaflet of multilingual instructions and a needle'INFILA' in gold writing on the front 'INFILA A60 Automatico Automatic needle threader' in blue on the backassistive devices, ditta fenzo martinelli
