General safety notes for changing the oil

NOTICE
Impermissible mixing of oils leads to damage
Impermissible mixing of oils leads to:
• Darkening
• Sediment
• Foam formation
• Change of the viscosity or reduced corrosion protection
• Wear protection.
When changing oil of the same type, the residual volume of oil in the gearbox should be
kept as low as possible. Generally speaking, a small residual volume will cause no particular
problems.
Gear oils of different types and by different manufacturers must not be mixed. Have the
manufacturer confirm that the new oil is compatible with the remaining volume of used oil.
If very different types of oil or oils with very different additives are changed, always flush
out the gearbox with the new oil. When changing from mineral oil to polyglycol oil (PG) or
vice versa, it is vital to flush the gearbox twice. All traces of old oil must be completely
removed from the gearbox.
NOTICE
Contaminations of the oil impair the lubricity
Do not mix the gearbox oil with other substances.
Do not flush with paraffin or other solvents, as traces of these substances will always remain
inside the gearbox.
