Think they are about 400kg all up so you may not get it down to 200Kg

I know it’s a old thread but other members are maybe looking for this information. I agree with David. I took out the levelling bboltsout of the Feet & used castors that had a M12 bolt on & just put them in the levelling foot. I had to move my 330IS up a 4″ step in to my workshop I got it to the step with a pallet truck then remembered i had some 100mm castors, they are actually still on the lathe it makes it easy to move & with the brakes on it dosent move when using it,  I sold a TS10.20 to get this 330IS & the 330is is alot larger in all ways H/W/L and it weighed 390KG .The TS10.20 was easy to move in comparison even up the step on a pallet with a pallet truck,  I just put the forks in half way with 3Tonne skates on the other end but the 330IS was alot heavier & longer so would not go up, so I got the light (tailstock end up the step & put castors on the heavy end then jacked it up & pulled it in the door then put on the other 2 castors. I tryed this with a hardinge chucker on its base & @800kg it made it easy to move but you have to get castors that are over rated for your weight . I used 700kg castors for the Boxford & 1000kg one’s for the hardinge
