Recommended lubricants


The excavator is shipped 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) in all seasons.

The use of diesel fuel with a sulphur content of less than 0.10 % (1,000 ppm) is strongly
recommended.

When diesel fuel with a high sulphur content [between 0.50 % (5,000 ppm) and 1.0 %
(10,000 ppm)] is used, the engine oil and engine oil filter must be replaced at shorter inter-
vals (roughly half as long).

Never use diesel fuel with a sulphur content exceeding 1.0 % (10,000 ppm).

Diesel fuels complying with the current EN 590 or ASTM D975 are recommended.
