@zevo, here's the current status:
I confirmed with BendPak support that the cable retaining bolts were missing from my setup. They gave me the specs and I bought them from McMaster Carr rather than from their service line. I feel they should have comped me them but since they didn't offer I wasn't paying for that. I used a pair of c-clamps to bend the retaining clip back into spec and installed the bolt, installing a bolt on the other side was no problem.
Bendpak support also said some amount of blow-by from the piston is to be expected, and suggested connect a compressor to my air bottle, then run the lift up and down a few times to see if that would pump the fluid back to the "right" side of the piston. It did, and the hydraulics seem to work better now. Because it seems normal for fluid to be on the other side of the piston, I don't understand how the "air bottle" setup is ever supposed to work (the one that makes it so you don't need a compressor). When I bought the bottle setup I had read reviews here and elsewhere of people saying they were not worth it, and I now fully agree. Mine always leaked pretty badly before anyway, so I am going to remove it and re-route the return line to the motor. Also, I decided on my own it would be a good idea to replace the lock-release pressure valve, to be on the safe side. I think its fine but I can't be sure. I order that from Bendpak parts because I couldn't find anything I though would be a drop-in replacement somewhere else.
Lastly, I decided to have my lift bolted to the floor. Bendpak wanted way too much (I think $10/ea) for the concrete bolts, so I got the spec for those from the installation manual and ordered them from McMaster Carr as well.
I have a call in to an authorized Bendpak service company, I'm going to have them come check out the lift, adjust the cables (I know of at least one that is out of spec now) and bolt it to the floor. I'll either have them take out the air bottle or I will if I get to it by then.
I sent @jsk an PM but never heard back from him.
As it stands now, I did not feel Bendpak expressed any concern or apology over this problem. At the very least I would have appreciated comping the missing and replacement parts, and ideally they would have helped with some of the cost of a service techs visit and evaluation (though not the bolting to the floor, that's optional and my choice).
Also I'd like Bendpak to make sure never to work with the installer who installed my lift again. I bought the lift through ASE Deals, who recommended this installer and had the lift shipped to them.
So now I am (or will be soon) comfortable using my lift again, though I'm not very happy about how it was sorted out.
This is a pretty damning review. First and foremost, I am grateful that you and yours were not injured by this mis-installed lift. Very interesting that JSK never got back to you, even after requesting a PM.
