Problem Installing Drive Belt on Delta DP350
Be prepared for sticker shock on maintenance. The belt is not a standard "V" belt and a replacement one is $40.
I was not pleased when trying to replace the belt. Like you said, there are no instructions in the manual, and it is not a simple job. The pulleys are made from cheap casting metal and one of my pulley halves cracked and came off from one of my attempts.
The secret is to not remove the rear pulley with the spring, but the front one. Then when you go to put the belt back on, put it around the rear pulley first and pull hard on the belt so that the spring in the rear opens up and the belt comes forward. Then you can easily reseat the front pulley half with the belt in place.
The variable pulley over the motor has come apart.
There is supposed to be a snap-ring with covering a cap with a spring that compresses the pulley and holds it together. Maybe one of those pieces has broken or is worn out. Most online repair parts places have an exploded diagram of all the parts and where they go so you can identify a replacement.
How do you ajust the high and low speed on the
not sure if you have a dial on that press to adjust the speed. if it is a dial on the machine make sure you adjust it while it is running.... but it looks like it is belt driven and there will be a series of pullies under the top cover for adjusting the speed.

Check for power at the on switch. The switch on this machine should be electrical so yes it could go out. If it is not the electrical type then I would check to make sure that the internal switch did not brake or go bad.
