Just bought a Majik with Karousel bearing which the previous owner had set up 12 months ago, could I ask how do you check that there is sufficient oil in the bearing and if there isn’t enough how much would you insert into the bearing to ensure ample is inside, the tissue paper around the base trick doesn’t correct due to the large nut on the top. I looked at the bearing after transporting it with the sub platter supported but would like to ensure there is enough in. Thanks
