I read it as I go & keep it handy. Also, I take the classes - but I think they are more beneficial after you've used the machine awhile, not when it's brand new. It's important to be able to utilize all of the new features of your machine.

I read the manual cover to cover, view the CD, and then go to web sites.

If my new machine is the same manufacturer as the old one, I just scan the manual. I always look over the index carefully then I get started sewing. Whenever I have a problem, I look up the directions, put a sticky on that page, and move forward. So far so good. No problems with this system for me.

By nature I just jump in, but I don't have a computerised machine. If I had a sewing machine that had cost me hundreds (or thousands!) of pounds I suspect I would be rather more cautious (overwhelmed?!) and hug my manual.

But with my current machine I fiddle first, and then refer to the manual if I can't figure it out after a while.

I just jump in and look something up if I need to

Manuals are a must to read with the newer and more complex/expensive machines....that's where a little knowledge can be dangerous! For the last three machines, I have used tabs for quick reference. Well worth it.

OMG! Definitely read that manual....the $$$$$ of these machines and the highly sophisticated computerization of them is enough to scare one into grabbing that little book and read......more than once, I found! .....and still keep that "book" close by with my notes added. But, I love to read...have been known to read bottle/can labels...shhh!

Yes, I read the manual...and even on my older machines, I go back for reviews...makes a big difference!

Since only one of my machines came with a manual (and that one was just like the one I learned to sew on) no I don't read the manual first.
However I do like to know what model machine it is so if I have issues I can look online and find out if I'm using the right bobbin, have it threaded correctly, etc.

I just found a "new" one today for $3.99 at a nearby Goodwill. It is from the mid 60s. Needs a bit of cleaning up and a bobbin cover and bobbin.
