New Cobra Class 4

Recommended Posts

Never had a machine before, just hand stitched so i decided to try a machine. I do mostly biker bags, belts, tank panels etc. Got the machine Fri night and set it up, very intimidating to a newbie, so i spent the weekend getting aquainted with it, not touching it much except to polish it a little. Today i figured i'd give it a try, only after talking to Steve first. The thread was already threaded, no spool of thread attached though as there was enough from the factory test to give it a try as per Steve, i practiced some stitches and even practiced back stitching some to lock it in. Really felt good about it. So i dethreaded what was left in the machine, left the bobbin thread alone as there was plenty there, and i threaded the top thread as per dvd instructions and looks good so as i was watching the dvd to sew it only sewed in reverse and punched holes in the leather, the handle was not in reverse. HELP!!!!!!!!. Waiting on a call from Steve now.(feeling sorry for him with me as a newbie for a customer)

Pull the stitch length lever all the way down to put it into forward motion. Turn the limiter nut away from the lever to allow it to go down all the way. Pull the thread out of the needle and up through the take-up lever. Pull the hand-wheel towards you from the top (Counterclockwise) and watch the feed dog. It should move to the front with the needle and inside foot, then rise slightly above the throat plate, then move backwards, then drop down and begin this cycle again.

If the motion is correct with the lever way down, move it all the way up and repeat the process. Now, the feed dog should start at the back, lift, move forward, drop and move back for the next stitch. If this happens, the machine is operating normally.

Rethread the top thread through the take-up lever, then down through the formed loop, through the hole above the needle, then through the needle's eye, from left to right. Insert a piece of leather. Lower the feet if they were lifted up, until they make contact with the leather. Rotate the wheel towards you again and see if she sews at all.

Report back. Time to eat dinner. BRB...

Thank you very much for the reply Wiz. Well i did what you said and with only turning the hand wheel counterclockwise it works fine but as soon as i hit the motor throttle it goes the opposite way, or in reverse. Really stumped. Still waiting on Steve to call btw.

The motor is probably gotten reversed someway or the other. I do it to students once or twice to keep their attention. HTH Ken

Ha, i did figure that out though, very educating and making me more intament with it. Must have pressed the arrow on the motor lcd screen too many times. So now it is going in the right direction it only punches holes and does nothing with the thread, doing it exactly as dvd shows??? What did i get myself into!!!:,) ThankS and you sound like a good teacher

look the motor over close some motors have a switch to reverse the rotation. If you fine one flip it the other way and try it.

PS I'm to slow glad you got it fixed

If you have it turning the right way, then you must have it threaded incorrectly, assuming it was sewing fine before you rethreaded it. I would suggest you follow the book and check your threading. Wiz can probably thread one blindfolded after being turned around several times. Be sure your thread is being threaded from left to right through the needle. I don't have a video for mine but have learned to thread from scratch. Unless you changed something other than threading it, it almost has to be the threading. Make sure it is turning the right way. Flywheel turning toward you when the stitch length lever is down. HTH Ken

oK,I GOT IT!! Forgot to rethread through the take up lever. Working like it should, now to start wasting alot of leather for this uphill learning curve. Thanks all for the help and being a total newbie to a machine i hope to entertain all of you machine pros with mucho more stupid questions. At least i am moving foreward because the reverse motor thing seems funny to me now and would laugh too to see that post. I think i might like this forum. Thks again.

that demonstrates how to thread a similar sewing machine with a different brand name. The threading path is identical for your machine.

just a small tip. When I change the thread on my Cobra, I cut the thread behind the tension disk and knot the new thread at the cut. Using the presser foot lever in the up position, the knot will easily pass through all the tensions and the take up arm. Then all you have to do is come down and thread the needle.

I do this on every one of my sewing machines. It is a real headache saver.

Hi franko:

At least you didn't put your servo motor into reverse on accident like I did once. lol I was befuddled for a long time until David at Cobra sent me a PDF on how to fix that. ;)

Take your time, you'll get this sewing thing down in no time at all.

Finally getting into my new Class 4, pics of practice stitches attached. Not so fearfull of the machine as i am getting aquanted with it, and loving the learning curve. The wrist band is the 1st finished practice piece and now onto fork bags and saddle bags. A little more practice for the back loch stitching but will conquer :dance:
