The excavator is shipped filled with ESSO NUTO H46 hydraulic oil.
If bio oil is used, please contact your KUBOTA dealer.
Use only API CF or API CI-4 grade engine oil. Do not use different grades, such as CF-4,
CG-4 or CH-4.
For the drive units use gear oil SAE 90 (API, CLA/GL5) all year round.
The use of diesel fuel with a sulphur content of less than 0.10% (1,000 ppm) is strongly
recommended.
If diesel fuel with a high sulphur content is used [sulphur content from 0.50 % (5,000 ppm)
to 1.0 % (10,000 ppm)], then the engine oil and oil filter will have to be replaced at shorter
intervals (approx. half as long).
Do not use diesel fuel with a sulphur content of more than 1.0 % (10,000 ppm).
Diesel fuels in accordance with the current EN 590 or ASTM D975 are recommended.
