1. Make certain the power supply is plugged in to the wall outlet securely and that the wall outlet has power. Check that the foot switch and clip cord connections are secure.
2. Broken wires in the clip cord due to wear can cause a loss of power to the machine. The components inside footswitch can also fail with time, bothe are difficult to identify where the failure might be. It would be wise to have both an additional clipcord and footswitch on hand to determine which item may have failed. It also gets you back making money while ordering a replacement for the failed component.
3. Do a visual inspection of the machine checking for any bare wire touching the frame, this causes a short. If you find a bare wire touching the frame remove the clip cord from the machine and either insulate the bare wire using a small piece of electrical tape (temporary fix only). Replace the component as soon as possible.
4. Check the contact post to ensure that there is no obstruction between the end of the post and the spring. You may need to file the end of the contact post that touches the spring to ensure a clean contact area. (File contact post daily as a preventative measure.)
