B Fuel
Fuel is flammable and can be dangerous. You should
handle fuel with care.
CAUTION
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 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.
C 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.
No.2-D is a distillate fuel oil of lower volatility for engines
in industrial and heavy mobile service.
(SAE J313 JUN87)
Grade of Diesel Fuel Oil According to ASTM D975
The cetane number is required not to be less than 45.
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.
