| The chain will hang out, just did bearings on the roller shaft on the door this past week on my 855, deflated the bags, cracked the door open, all the slack ran out the door bottom. We then pulled that shaft out with the door supported on a small steel stand. Put it back in and had to air the bags to get the chain tight to do anything. That was not even running it, I would guess if the op ran it with no air that slack issue would be way worse, like in the picture. | |
