5. Fuel, Lubricant & Coolant

5.1 Fuel

(1) Fuel Selection

The following specific characteristics are required for the

diesel fuel.

1. Must be free from minute dust particles.
2. Must have adequate viscosity.
3. Must have high cetane value.
4. Must have high fluidity at low temperature.
5. Must have low sulfur content.
6. Must have little residual carbon.

Diesel fuels

(2) Fuel Requirements

CAUTION:

The fuel injection pump, injector or

other parts of the fuel system and the engine can
be damaged if you use any fuel or fuel additive
other than those specifically recommended by
Shibaura. Such damage is not Shibaura's responsi-
bility, and is not covered by the Warranty. To help
avoid fuel system or engine damage, please be
aware of the following:
Some service stations mix used engine oil with
diesel fuel. Some manufacturers of large diesel
engines allow this; however, for your diesel
engine, do not use diesel fuel which has been con-
taminated with engine oil. Besides causing engine
damage, such fuel can also affect emission control.
Before using any diesel fuel, check with the ser-
vice station operator to see if the fuel has been
mixed with engine oil.
Do not use any fuel additive (other than as recom-
mended under "Biocide" in this section). At the
time this manual was printed, no other fuel addi-
tive was recommended. (See your authorized
dealer to find out if this has changed.)

Your engine is designed to use either Number 1-D or

Number 2-D diesel fuel. However, for better fuel economy,
use Number 2-D diesel fuel whenever possible. At tempera-
tures less than -7°C, (20°F), Number 2-D fuel may pose oper-
ating problems (see "Cold Weather Operation" which
follows). At colder temperatures, use Number 1-D fuel (if
available) or use a "winterized" Number 2-D (a blend of

Number 1-D and Number 2-D). This blended fuel is usually
called Number 2-D also, but can be used in colder tempera-
tures than Number 2-D fuel which has not been "winterized".
Check with the service station operator to be sure you get the
properly blended fuel.

Note that diesel fuel may foam during a fill-up. This can

cause the automatic pump nozzle to shut off even though your
tank is not full.

CAUTION:

Do not use home heating oil or gaso-

line in your diesel engine; either may cause engine
damage.

(3) Handling of the Fuel

Fuel containing dust particles or water will cause engine

failure. Therefore, the following notice must be observed.

1. Prevent dust particles or water from entering when filling

the fuel tank.
When fueling is done from an oil drum directly, keep the
drum stationary for a period of time to allow the sediment
to go to the bottom of the drum.

2. Always fully fill the fuel tank. Drain the sedimented par-

ticles in the fuel tank frequently by opening the tank
drain and draining the fuel into approved fuel containers.

(4) Water in Fuel

During refueling, it is possible for water (and other con-

taminants) to be pumped into your fuel tank along with the
diesel fuel. This can happen if a service station does not regu-
larly inspect and clean its fuel tanks, or if a service station
receives contaminated fuel from its supplier(s).

To protect your engine from contaminated fuel, there is a

fuel filter system on the engine or equipment which allows
you to drain excess water.

WARNING:

The water/diesel fuel mixture is

flammable, and could be hot. To help avoid per-
sonal injury and/or property damage, do not touch
the fuel coming from the drain valve, and do not
expose the fuel to open flames or sparks.
Be sure you do not overfill the container. Heat
(such as from the engine) can cause the fuel to
expand. If the container is too full, fuel could be
forced out of the container. This could lead to a
fire and the risk of personal injury and/or vehicle
or equipment damage.

(5) Biocides

In warm or humid weather, fungus and/or bacteria may

form in diesel fuel if there is water in the fuel.

CAUTION:

Fungus or bacteria can cause fuel sys-

tem damage by plugging the fuel lines, fuel filters
or injector. They can also cause fuel system corro-
sion.
