Hello,Are you belt driven or direct drive? Either way, check all the parts that connect. My presses are direct drive, and if there’s so much as a piece of masking tape on the flywheel, it’ll throw off the whole operation and it won’t spin. There’s also a chance that the brushes on the motor are worn and aren’t touching the copper wheel inside the motor (I know, my layman’s terms are atrocious). These aren’t actually brushes, per se, but a solid chunk that is held in place and must connect to the copper wheel on the inside. Sometimes when they’re worn you can adjust whatever mechanism is holding them in place to lower them a bit. I used to have this problem a lot, and I recall a bit of sparking when adjusting the brushes, but they’ve been good to go for some time now. Take a look and see if you have these in the motor (sometimes you have to lift up a cap, but they’re generally towards the outside edge). Motors need oil, too, so make sure you’re on top of that. Oh, and both of mine have an arm that comes up and out and is directly connected to my speed control. Because it’s just out in the open, it can get banged into by an errant knee (ouch), and then it completely throws off the speed control so that even when you’ve turned it up, it’s not enough. Kind of a Duh! moment, but it just happened to us last week after having an open house… someone must have bumped it out of place. In that case, you just have to move it by hand to a different position and readjust your speed control Motors are also motors, so if you can’t figure it out, you can probably find a small shop to take it to or that might come by to check it out.Hope that helps!Jen
