A The jobs indicated by must be done after the first 50 hours of operation.
*1 Air cleaner should be cleaned more often in dusty conditions than in normal conditions.
*2 After 6 times of cleaning.
*3 Consult your local KUBOTA Dealer for this service.
*4 Replace only if necessary.
A
The items listed above (@ marked) are registered as emission related critical parts by KUBOTA in the U.S. EPA
nonroad emission regulation. As the engine owner, you are responsible for the performance of the required
maintenance on the engine according to the above instruction.
Please see the Warranty Statement in detail.
A Changing interval of engine oil
* 90 mm (3.54 in.) oil pan depth is optional.
(Standard replacement interval)
A American Petroleum Institute (API) classification: above CF-4 grade

Ambient temperature: below 35 C (95 F)
Lubricating oil
With strict emission control regulations now in effect, the CF-4 and CG-4 engine oils have been developed for use with
low sulfur fuels, for On-Highway vehicle engines. When a Non-Road engine runs on high sulfur fuel, it is advisable to
use a "CF or better" classification engine oil with a high Total Base Number (a minimum TBN of 10 is recommended).
A Lubricating oil recommended when a low-sulfur or high-sulfur fuel is employed.
: Recommendable X : Not recommendable
* TBN: Total Base Number
**Fuel
A Diesel Fuel Specification Type and Sulfur Content % (ppm) used, must be compliant with all applicable emission
regulations for the area in which the engine is operated.
A
Use of diesel fuel with sulfur content less than 0.10 % (1000 ppm) is strongly recommended.
A If high-sulfur fuel (sulfur content 0.50 % (5000 ppm) to 1.0 % (10000 ppm)) is used as a diesel fuel, change the engine
oil and oil filter at shorter intervals. (approximately half).
A DO NOT USE Fuels that have sulfur content greater than 1.0 % (10000 ppm).
A
Since KUBOTA diesel engines of less than 56 kW (75 hp) utilize EPA Tier 4 and Interim Tier 4 standards, the use of
ultra low sulfur fuel is mandatory for these engines, when operated in US EPA regulated areas. Therefore, please use
No.2-D S15 diesel fuel as an alternative to No.2-D, and use No.1-D S15 diesel fuel as an alternative to No.1-D for
ambient temperatures below -10 (14 ).
No.1-D or No.2-D, S15 : Ultra Low Sulfur Diesel (ULSD) 15 ppm or 0.0015 wt.%
A CJ-4 classification oil is intended for use in engines equipped with DPF (Diesel Particulate Filter) and is Not
Recommended for use in Kubota E3 specification engines.
