10 MAINTENANCE
ENGLISH
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.
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).
ALubricating oil recommended when a low-sulfur or high-sulfur fuel is employed.
{ : Recommendable : 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°C (14°F).
No.1-D or No.2-D, S15 : Ultra Low Sulfur Diesel (ULSD) 15 ppm or 0.0015 wt.%
A If the engine is to be operated within the European Union on diesel or non-road gas-oil, a fuel with sulfur content
not greater than 10 mg/kg (20 mg/kg at point of final distribution), a cetane number not less than 45 and a fatty acid
methyl ester (FAME) content not greater than 7 % volume per volume (v/v) shall be used.
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.
A Oil used in the engine should have API classification and Proper SAE Engine Oil according to the ambient
temperatures as shown below:
A Use of the following oil not only disallows the engine from performing well in low temperatures until it warms up
sufficiently but may also lead to excessive engine wear or engine seizure.
• Oil with a viscosity higher than 10W-30
• Oil not recommended by KUBOTA
