BChecking fuel level and refueling
Fuel is flammable and can be dangerous. You should
handle fuel with care.
To avoid personal injury or death:
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 Do not fail to stop the engine before
refueling. Keep the engine 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 battery or when refueling.
A Check the fuel systems at a well
ventilated and wide place.
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 Cetane Number : The minimum recommended Fuel
Cetane Number is 45. A cetane number greater than
50 is preferred, especially for ambient temperatures
below -20
(-4
) or elevations above 1500 m (5000
ft).
A Diesel Fuel Specification Type and Sulfur Content %
(ppm) used, must be compliant with all applicable
emissions regulations for the area in which the engine
is operated.
A DO NOT USE Fuels that have sulfur content greater
than 0.0015 % (15 ppm).
A Diesel fuels specified to EN 590 or ASTM D975 are
recommended.
A No.2-D is a distillate fuel of lower volatility for engines
in industrial and heavy mobile service.
(SAE J313 JUN87)
A These engines utilize 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
(14
).
A When using biodiesel fuel, replace the fuel filter
cartridge, fuel hoses and clamp bands with new ones
at half intervals.
1) SAE : Society of Automotive Engineers
2) EN : European Norm
3) ASTM : American Society of Testing and Materials
4) US EPA : United States Environmental Protection
Agency
5) No.1-D or No.2-D, S15 : Ultra Low Sulfur Diesel
(ULSD) 15 ppm or 0.0015 wt.%
A Be sure to use a strainer when filling the fuel tank, or
dirt or sand in the fuel may cause trouble.
A Do not run the fuel tank level too low or completely out
of fuel. You may experience improper engine running
and/or a DTC (Diagnostic Trouble Code) error code
may be recorded in the Engine Control. Additionally,
fuel system bleeding may be necessary if air enters
the fuel system.
A Fuel must be controlled carefully to prevent the
additives being mixed into fuel such as fuel tank anti-
oxidants, water remover, antifreeze and so on.
Otherwise, the fuel filter may become clogged, the fuel
lubrication part in the injector may not slide properly,
and the engine may be adversely affected, resulting in
a malfunction.
BChecking coolant level
Coolant will last for one day's work if filled all the way up
before operation start. Make it a rule to check the coolant
level before every operation.
BBiodiesel fuel (BDF)
When using biodiesel fuel, make sure that it meets the
latest regional standards. See the table below.

make BDF

C Precautions in handling Biodiesel fuels
1. Keep the fuel tank full whenever possible to prevent
water vapor from accumulating inside the fuel tank.
Tighten up the fuel tank filler cap to avoid the entry of
moisture.
2. Routinely check the oil level before the operation. Also
strictly follow the specified oil change intervals.
3. Biodiesel fuels (BDF) during the supply process or in
the machine easily deteriorate due to oxygen, water,
heat and other foreign substances. With this in mind,
take the following precautions.
A Do not leave those fuels in the fuel tank or a
metallic drum longer than 3 months.
A Before storing the machine for a prolonged period,
change such fuel for a conventional type of diesel
fuel and operate the machine for 30 minutes or
longer to clean up the fuel system.
