I will recomend Read your instructions or user manual, section unfold or assembly the treadmill.

If you do not have the owner or user manual, go to the web page. www.proform. com then customer service, and then parts & manual, give your model, serial number, and download free, and ready.

However you must take carefully and pacience with this. sincerely.

Please read you user manual, and read the section how unfold the equipment.

You may have damaged the treadmill when folding it up. If the incline was not lowered to its minimum position, the frame can be damaged.
To lower the treadmill, all you do is release the latch and lower the deck of the treadmill to the floor.
There are many Proform machines known as "785" including a number of elliptical trainers. An actual model number would make diagnosis much easier...

The pin should come out easily. If not, see the manual you can get at www.iconservice.com or maybe Treadmill Parts

Ijust purchased a used treadmill. how do I unfold it?

there is a clip latch that u need to move to pull the treadmill back down, its on the left side on top

From the owners manual:

HOW TO LOWER THE TREADMILL FOR USE

1. Hold the upper end of the treadmill with your right hand.
Pull the latch knob to the left and hold it. It may be necessary
to push the frame forward as you pull the knob to
the left. Pivot the frame downward and release the latch
knob.

2. Hold the metal frame firmly with both hands and lower
it to the floor. CAUTION: Do not grip only the plastic
foot rails or drop the frame to the floor. Bend your legs
and keep your back straight.
