The Optimat 2550 represents an era when machines were built with substantial iron and simple, repairable mechanics. If you find a well-maintained unit with low hours and a Tersa cutterhead, it will outperform many new combination machines under $3,000.
Modern warehouses use AGVs with hydraulic lifts. These systems stop and start frequently, causing "micro-dieseling" in standard fluids. Optimat 2550 has a high auto-ignition temperature and superior air release properties, preventing foam cavitation that destroys pumps. optimat 2550
