If it’s a 215 there is a tensioning bolt in the bottom end of the track.
Put the lift in slack chain, then release the top chain fixings and the wind through about a foot of chain below the carriage (or physically ease the carriage down a little) this will give you some free chain to work with.
Remove the bottom end cap and there will be a 5mm allen bolt holding the chain fixing in place, undo it and ease out the bottom chain bracket.
On the bottom is a 13mm nut on a threaded bar which adjusts the chain tension, or, if required, links can be removed as the final link is a joiner.
Just don’t tension the old thing too highly as all you will do is increase roller wear, aim to have the chain forming a slight bow when the lift is at top limit and for the chain to be just clear of touching track at all times during travel.
If it’s a 205 the the spring in the bottom track fixing will have broken – try fitting the footrest holdup spring from a 250 or 260 as a fix on one of these.
