guys
just had to move my machines and therefore had to dump the coolant.
the coolant was starting to get a bit funky in the lathe a few weeks before the move but just waited till we moved before i dumped it.
now that we have moved i have cleaned up the chip tray and coolant tank and need to add new coolant.
should i be doing something about cleaning the rest of the machine out so that any old coolant in the lines or wherever it might be doesn't contaminate the new coolant?
i use a castrol coolant if that helps.
if i do have to give the lines and internals a clean up what is usually the best way to do this.
just don't want 100 litres of new coolant going off in record time.
