Do not mix oils of different makes or specifications. Make sure also that the oil is highly resistant
to foaming and is EP (Extreme Pressure) rated.
If you do not have the same type of oil, completely drain the gearbox and flush it out thoroughly with the
new oil to remove all traces of the old oil and any contaminants from inside the casing before filling the
gearbox with the new oil.
Oil level can be checked by removing the oil level check plug and checking that the oil spills from the
bottom edge of the hole.
Only use recommended oils to fill and top up the gearbox.
5.9.1 Recommended / permitted lubricants
When using a lubricant other than the recommended SHELL lubricant, be sure it is a synthetic lubricant
with equivalent viscosity and composition and added with adequate anti-foaming agents.
