Watched this and another video before assembling my new Sole F85. My unit didn't come with a safety pin at the base of the left arm. After assembly, when I turned on the power, nothing came on. I could see the power was connected because the red light lit up. The console remained black and the start key didn't respond. The safety key was in place. So.....I checked all plugs to make sure they were correctly connected and not pinched. Still no power. Really disappointed for the cost of this treadmill. Will call technical service when they open on Monday. Would not recommend at this point.
