Procedure
1. Allow the geared motor to run for a short time. Wear and contaminant particles are visible
in the oil shortly after shutting down.
2. Switch off the power supply to the drive unit.
3. Remove the sealing element at one of the points marked with the symbols listed above.
4. Remove some oil, using a suction pump and a flexible hose, for example.
5. Check the condition of the sealing ring on the sealing element and replace the sealing
ring if necessary.
6. Seal the gearbox with the sealing element.
7. Check the oil for abnormalities. If you detect any abnormalities, change the oil
immediately.
8. Check the oil level.

You have now checked the oil quality.
8.2.6 Changing the oil
8.2.6.1 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.
