Help. My machine is loose on the carriage.

[loraquilts]

Yesterday when trying to show someone my Ultimate I, I was trying to show her how easy it was to make beautiful feathers.  Unfortunately, I was not able to make nice looking feathers because when stitching on a slight diagonal, the machine would "chunk" as if it were going up a stair step.  Sorry, I don't really know how to describe it any better.  

After she left, I started looking for obstructions, loose thread in the wheels, etc. etc.  What I discovered is that the machine head, which is connected to the carriage at the rear wheels and midway over the center wheels, is loose over the center wheels.  How can I fix this?  Do I have to remove the machine head from the frame (please, please, please say no ; )?  What type of adjustment do I have to make to secure the machine head to the carriage again?  Does anyone know whether the screws that hold in this area are flat, phillip, or allen?  

I don't want to bugger this up, so any kind words of help and encouragement will be greatly appreciated.  Thanks so much!

Lora, sorry no one has answered yet.  I don't know how to fix this, but I suggest sending an e-mail to service.

 

Good luck!

Are you talking about the aluminum axle being loose on the bottom of the head?  From memory they are held on with two Phillips screws each and I think you can access them by laying on your back under the machine.
