plug.
- Remove drain plug (2) and its washer.
- Allow oil to drain completely.
- Wait for dripping to stop.
- Clean and reinstall drain plug (2) and its
washer. Replace if necessary.
- Pour the correct oil quantity and quality through the
opening of the filler plug (1).
- Check Gyrodine gearbox level:
• The "MAX" level corresponds to the mark on the
dipstick plug.
• The "MIN" level corresponds to the end of the
dipstick plug.
- Clean and reinstall dipstick plug (1). Replace it if

Before draining oil, operate the machine for a
few minutes so that the oil warms up.
The Gyrodine gearbox is lubricated with 5.5 L (1.42 US gal) of SHELL SPIRAX extreme-pressure gear
oil with SAE 80W90 viscosity grade API and GL5.
When draining and refilling, it is recommended to use either a mineral base oil with viscosity grade
SAE 80W90 and API grade GL5, or a synthetic base oil, type PAO (Poly-Alpha-Olefins) with a viscosity
grade equivalent to SAE 80W90.
