Michelle on-route service.

I own Michelle Gyro SE turntable with Incognito RB300 arm.
This is so-far the turntable that I've been using quite a while and plan to use it even much more.
I wonder how often I should refill the oil in plater spindel?
Should I clean or re-grease suspention?
I also would like to know if I have to do anything with arm in that sence.
