Appreciate your inquiry atpchas. you sent 3 versions of parts list due to closely related saws but they all duplicate the error being discussed. Specifically looking at "036 IPL PDF" 2mb, on page 12 item #31, switch shaft. Shown as being part # 1125 182 0901, but I know from previous tortuous and expensive trial and error this does not work. Original shaft said 1121 182 0900 on it and when got a necessarily used one of those was saved.
As can see no asterisk after this switch shaft.
Also the contact spring. This parts list does show a present #29 and asterisked previous #30 choice but the other 2 parts list only show present spring and I know that spring to be different. So in this case two of the parts lists would lead one astray.
