Service and maintenance8.2 Checking and changing lubricants8.2.6 Changing the oil8.2.6.1 General safety notes for changing the oilCAUTIONAn impermissible mixture of oils will lead to clouding, depositing, foam formation, changesto the viscosity or reduced protection against corrosion and wear.When changing oil of the same type, the residual volume of oil in the gearbox should bekept as low as possible. Generally speaking, a small residual volume will cause noparticular problems.Gear oils of different types and by different manufacturers must not be mixed. Have themanufacturer confirm that the new oil is compatible with the remaining volume of used oil.If changing very different types of oil or oils with very different additives, always flush outthe gearbox with the new oil. When changing from mineral oil to polyglycol oil (PG) or viceversa, it is vital to flush the gearbox twice. All traces of old oil must be completely removedfrom the gearbox.CAUTIONGear oils must never be mixed with other substances. Do not flush with paraffin or othersolvents, as traces of these substances will always be left behind inside the gearbox.NoteThe oil must be warm. If it is too cold, it will flow too sluggishly to drain properly. If necessary,run the gearbox for 15 to 30 minutes to warm it up.BA 2010Operating Instructions, 05/2011 65
