The lift handles are M6. Universal pin spanners work well for the nut, though the holes are 3.5mm while most cheap universal spanners use 4mm pins. You can use those but will need to file the pins down. There are a few out there that are 3mm: http://a.co/d/7Nf7DzJ
Read there reviews as I’ve seen some where 3mm pins are claimed but the reviews say otherwise.
