Oil change intervals
The longest permissible time a lubrication oil
should remain in an engine is 1 year. If the follow-
ing oil change intervals are not reached over a pe-
riod of 1 year, the oil change should be performed
at least once per year, irrespective of the operating
hours reached.
API: CF, CF-4,
CG-4,CH-4 and
CI-4 = 250 operating hours
Fuels
Quality
Cetan index number: The recommended minimum
index number for the Cetan value is 45. A Cetan
index number higher than 50 should preferably be
used, especially at ambient temperatures below -
20 °C and when working at altitudes of 1500 m
and more.
Diesel fuel specifications: With respect to the per-
centage (ppm) of sulphur the fuel used in the en-
gine must comply with all relevant exhaust
emission regulations in the are of use of the en-
gine.
It is highly recommended to use a fuel with a sul-
phur content of less than 0,10 % (1000 ppm).
When using a diesel fuel with a high sulphur con-
tent of 0.50 % (5000 ppm) to 1.0 % (10.000 ppm),
the engine oil change intervals must behalved.
Do not use any fuels with a sulphur content of
more than 1,0 % (10000 ppm).
It is recommended to use diesel fuel that complies
with the specifications EN590 or ASTM D975.
Diesel fuel with the designation no. 2-D is a destil-
late fuel with low volatility, which is especially suit-
able for industrial engines and heavy-duty
commercial vehicles (SAE J313 JUN87).
Since KUBOTA diesel engines with a rated power
of less than 56 kW (75 HP) comply with the ex-
haust emission standard of EPA
*
-stage 4, the use
of low or ultra-low sulphur fuel is mandatory for
these engines, if the engines are operated within
the validity area of the EPA standard. As an alter-
native to no. 2-D you may also use diesel fuel no.
2-D S500 or S15; with ambient temperatures be-
low -10 °C the diesel fuel no. 1-D S500 or S15
should be used fir no. 1-D.
The fuel level should always be topped up in due
time so that the fuel tank is never run dry, as oth-
erwise filter and injection lines need to be bled.
Winter fuel
Fire hazard!
Diesel fuels must never be mixed with gaso-
line.
For winter operation use only winter diesel fuel, to
avoid clogging because of paraffin separation. At
very low temperatures disturbing paraffin separa-
tion can also be expected when using winter diesel
fuel.
Coolant
Always use a mixture of anti-freeze agent and
clean, dehardened water with a mixing ratio of 1:1.
Under particularly extreme temperature conditions
you should consult the service representation of
the engine manufacturer with respect to the anti-
freeze agent to be used.
There are various types of anti-freeze agents
available. For this engine you should use ethylene
glycol.
Before filling in the coolant mixed with anti-freeze
agent the radiator must be flushed with clean wa-
ter. This procedure should be repeated two to
three times to clean the inside of radiator and en-
gine block.
Mixing the anti-freeze agent: Prepare a mixture of
50 % anti-freeze agent and 50 % low mineral,
clean water. Stirr well before filling it into the radi-
ator. The method for mixing water and anti-freeze
agent depends on the brand of the anti-freeze
agent. In this respect see standard SAE J1034
and also the standard SAE J814c.
Add anti-freeze agent: If the coolant level drops
because of evaporation,only clean water is to be
used for topping up. In case of leakages you must
always fill in anti-freeze agents of the same brand
and the same mixing ratio.
