FUEL
Fuel is flammable and can be dangerous. You should
handle fuel with care.
To avoid personal injury:
A
DO NOT mix gasoline or alcohol with
diesel fuel. This mixture can cause
an explosion.
A
Be careful not to spill fuel during
refueling. If fuel should spill, wipe it
off at once, or it may cause a fire.
A
Stop the engine before refueling.
Keep the machine away from the fire.
A
Be sure to stop the engine while
refueling or bleeding and when
cleaning or changing fuel filter or fuel
pipes. DO NOT smoke when working
around the machine or when
refueling.
A
Check the above fuel systems in a
well ventilated and open place.
A
When fuel and lubricant are spilled,
refuel after the machine cooled
down.
B
Fuel Level Check and Refueling
1. Check to see that the fuel level is above the lower limit
of the fuel level gauge.
2. If the fuel is too low, add fuel to the upper limit. Do not
overfill.
A
No.2-D is a distillate fuel oil of lower volatility for
engines in industrial and heavy mobile service.
(SAE J313 JUN87)
A
Diesel fuels specified to EN 590 or ASTM D975 are
recommended.
A
Cetane Rating : The minimum recommended Fuel
Cetane Rating is 45. A cetane rating greater than 50
is preferred, especially for ambient temperatures
below - 20 C (-4 F) or elevations above 1500 m.
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
Be sure to use a strainer when filling the fuel tank, or
dirt or sand in the fuel may cause trouble in the fuel
injection pump.
A
Always use diesel fuel. You are required not to use
alternative fuel, because its quality is unknown and
affect the generator performance. Kerosene, which is
very low in cetane rating, adversely affects the engine.
Diesel fuel differs in grades depending on the
temperature.
A
Be careful not to let the fuel tank become empty, or air
can enter the fuel system, necessitating bleeding
before next engine start.
