I am an owner of Toyota Ks901 Kr501,but I can not find kiintting machine neddles to change,no neddles enough the machine is waste.
If you look on the under side/ back of the product there should be some serial or product numbers if you type in the model make and that number I think you will find an online manual or if you go on toyotas web site and search the make of this model you definitely find an online manual at some point
I have one. I believe I paid $20 for it. It is in used condition with a little writing on the inside and cover has some damage. If you are interested email me
