Bryan, you didn't say what size hose you are using on the 735. If it's the standard 2 1/2" hose necked up to mount to the 4" 735, you are creating too much back pressure. If your dust bucket is close to the machine, you could try using it without the vac. They used to sell a bag that would connect to the 735 outlet and you didn't need a dc or vac. The blower in the 735 should blow the chips into the bucket if it is close to it. Don't have any experience doing that, but heck you could try it to see if it would work. Couldn't hurt.
