Turntable maintenance??

I have a GyroDec and use it a couple times a week. Is there some maintenance I should be performing on the unit? I think it uses a seal bearing so I'm not sure about doing anything there. Ideas?
The GyroDec requires oil in the spindel well and is not of a sealed bearing design .........
Agree with the previous comment about the oil. The table will drag if the oil gets too low. I owned a gyrodec for several years and only once had to add oil. Once set up properly, does not require a lot of attention. Enjoy!
