I am looking for a free instruction manual for a Singer Merritt model 3145 sewing machine.

Most Singer Merritt sewing machines do not drop the feed dogs. Instead, you place a cover over the feed dogs. Here's one replacement for the cover: https://www.sewingpartsonline.com/feed-cover-plate-singer-360-sewing-machine.aspx . This fits the Merritt 2404 and Merritt 3130, among others.

Many Singer manuals are available here: https://www.singer.com/support . You need the model number to find a manual. The Merrit 2404 manual is here: http://www.singer.com.br/wp-content/uploads/2014/02/Singer-Merrit-2404.pdf .

Please add a comment with the model number of your sewing machine to find out if a different feed dog cover is needed for your Merritt. I hope this helps.

There sure is! Just go to the Singer sewing machine site, and there's a page where you can type in your model and click the button, and your machine is right there for free download.

Here you go. This manual covers several models including yours.
