Don't seem to be getting full foot lift on a Consew 206RB-5

I recently bought a lightly-used Consew 206RB-5 with a servo motor for my leatherworking. Once I installed a speed reducer, it's a great machine, and sews beautifully. 

My issue is that even though the machine is advertised all over the place as having 3/8" capacity and a 9/16" max foot clearance, the presser foot won't lift more than around 3/8", even when using the knee lifter. It's definitely not lifting more than 1/2" because I have a 1/2" thick piece of oak that doesn't even come close to fitting under the foot at maximum lift.

Is Is there a way to adjust the foot lift height, could it be the thickness of the presser foot set I've got on there, is the machine maybe misadjusted, etc.? I'm not planning to sew more than the rated capacity, but I want to make sure the machine is working as designed.

The previous owner may have adjusted it down (less travel) if not needed to go that high.  Got the manual?  Those are decent little machines, and you CAN adjust the foot height up/down.

Should have checked the manual closer.  Let me see if that will solve the problem when I get home. Thanks, JLS

Knee lifter may be adjusted incorrectly; it could be so that the end point adjustment is engaging before the foot reaches maximum foot lift of 9/16"  It also could be that the knee lifter may be misaligned and not coming in contact correctly with the bell crank.  The best way to check is to manually push the lifting lever rod as far as it will go, then engage the knee lifter; if the lifter drops before it hits the knee lifter, you have to adjust for this.
