Changing to larger needle Juki DDL 8700
Yes, you have to re-time the hook when going up to a size 18 needle from the standard size 14 needle. No need to worry though, we show you exactly how to do it. The converse is also true, that if you are going down more than 3 sizes from the standard 14, that you will have to re-time the hook. You can use the method shown here to go in either direction.
