Page 26: Description Of Maintenance Activities
When changing oil, always use the same type of lubricant as that contained in the M73ES. Do not mix different types of oil, or oils from different manufacturers. Do not mix synthetic oils with mineral oils or other types of synthetic oil. -
Page 27: Lubricants
Thread Tightening torque (Nm) 9.4 Lubricants For its units, Montanari only approves CLP oils that contain ingredients according to DIN 51517-3, for increased corrosion protection, durability and reduced wear in mixed friction zones. We recommend that customers use one of the lubricants listed in the table, taking into account the viscosity grade specified on the plate. - Page 28 Synthetic oils have a wider temperature range and a higher viscosity index (i.e. a flatter viscosity-temperature gradient) compared with mineral oils. Approximate values for temperature range: • Mineral oils from about -10°C to +90°C (short term +100°C) • Polyglycol from about -20°C to +100°C (short term +110°C) Note: The maximum and minimum utilisation temperature (flash point, pour point) of certain gear lubricants may differ significantly from that of the figures shown.
