SME 30/2 Controller

Thanks everyone for your input. I am looking forward to listening to 30/2. The guidance you’ve all given me has helped ease my mind. I will use the existing controller as it seems buying a newer version yields few improvements. 
 Looks like all the tools etc are in the tonearm box. I will use the spare o-ring to get my measurements. The o-rings are offered in many materials, any input as to which is proper? 
 Thanks,

@hifipf … good chat! Red, I would do red o-rings. Would be kinda cool!

So, I discovered a little bit of the hydraulic fluid at base of the pillar.  Is this a big issue and if so serviceable?
 No reply from SME.  I have now sent 4 inquires.  I have never had this poor of service from a company so, I’m at a loss of words. 
 

The sub chassis was not locked down in transport but the it was lowered all the way down. As a result hydraulic fluid present. Everything else is fine. Bearing dead quite with  stethoscope and motor no issues.
 Any guidance on fluid leak? Cleaned everything up and so far nothing more has has appeared. Is this a serious issue and what would be involved if needed attention?
Thanks  

Update on fluid leak. After studying and thinking long and hard,I think I know what happened. When sub chassis was raised to its limits and released quickly a little bit of oil due to the sudden pressure of the quick release was forced out. After 2 days no fluid present and the hydraulic feel of all 4 posts seems fine. 
 Since it was such a small amount of fluid it seems fine. I will assume at this point with no additional appearance of fluid all is well.

 Thanks everyone for your input. It really guided me through the process.
