LV Operation Manual

DANGER

FIRE AND EXPLOSION HAZARD!

• Diesel fuel is extremely flammable and

explosive under certain conditions.

• Be sure to place the diesel fuel

container on the ground when
transferring the diesel fuel from the
pump to the container. Hold the hose
nozzle firmly against the side of the
container while filling it. This prevents
static electricity build-up which could
cause sparks and ignite fuel vapors.

• NEVER place diesel fuel or other

flammable material such as oil, hay or
dried grass close to the engine during
engine operation or shortly after shut
down.

• Failure to comply will result in death or

serious injury.

DANGER

FIRE AND EXPLOSION HAZARD!

• Diesel fuel is extremely flammable and

explosive under certain conditions.

• Before you operate the engine, check

for fuel leaks. Replace rubberized fuel
hoses every two years or every 2000
hours of engine operation, whichever
comes first, even if the engine has
been out of service. Rubberized fuel
lines tend to dry out and become
brittle after two years or 2000 hours of
engine operation, whichever comes
first.

• Failure to comply will result in death or

serious injury.

WARNING

HIGH PRESSURE HAZARD!

• Avoid skin contact with the high

pressure diesel fuel spray caused by a
fuel system leak such as a broken fuel
injection line. High pressure fuel can
penetrate your skin and result in
serious injury. If you are exposed to
high pressure fuel spray, obtain
prompt medical treatment.

• NEVER check for a fuel leak with your

hands. ALWAYS use a piece of wood
or cardboard. Have your authorized
Yanmar industrial engine dealer or
distributor repair the damage.

• Failure to comply could result in death

or serious injury.

WARNING

BURN HAZARD!

• Keep your hands and other body parts

away from hot engine surfaces such
as the muffler, exhaust pipe,
turbocharger (if equipped) and engine
block during operation and shortly
after you shut the engine down. These
surfaces are extremely hot while the
engine is operating and could
seriously burn you.

• Failure to comply could result in death

or serious injury.

WARNING

BURN HAZARD!

• If you must drain the engine oil while it

is still hot, stay clear of the hot engine
oil to avoid being scalded. Make sure
you wear eye protection.

• Failure to comply could result in death

or serious injury.

0000011en

CAUTION

• Only use diesel fuels recommended by

Yanmar for the best engine
performance, to prevent engine
damage and to comply with EPA / ARB
warranty requirements.

• Only use clean diesel fuel.

• NEVER remove inlet fuel screen from

the filler port. If removed, dirt and
debris could get into the fuel system
causing it to clog.

CAUTION

• Only use the engine oil specified.

Other engine oils may affect warranty
coverage, cause internal engine
components to seize, or shorten
engine life.

• Prevent dirt and debris from

contaminating the engine oil. Carefully
clean the oil cap / dipstick and the
surrounding area before you remove
the cap.

• NEVER mix different types of engine

oil. This may adversely affect the
lubricating properties of the engine oil.

• NEVER overfill. Overfilling may result

in white exhaust smoke, engine
overspeed or internal damage.

CAUTION

If any problem is noted during the visual
check, the necessary corrective action
should be taken before you operate the
engine.

DIESEL FUEL

Diesel Fuel Specifications

Diesel fuel should comply with the following
specifications. The table lists several worldwide
specifications for diesel fuels.

Additional Technical Fuel Requirements

• The fuel cetane number should be equal to 45

or higher.

• The sulfur content must not exceed 0.5% by

volume. Less than 0.05% is preferred.

• Bio-Diesel fuels. See Bio-Diesel Fuels on

page 29.

• NEVER mix kerosene, used engine oil, or

residual fuels with the diesel fuel.

• Water and sediment in the fuel should not

exceed 0.05% by volume.

• Keep the fuel tank and fuel-handling equipment

clean at all times.

• Poor quality fuel can reduce engine

performance and / or cause engine damage.

• Fuel additives are not recommended. Some

fuel additives may cause poor engine
performance. Consult your Yanmar
representative for more information.

• Ash content not to exceed 0.01% by volume.

• Carbon residue content not to exceed 0.35% by

volume. Less than 0.1% is preferred.

• Total aromatics content should not exceed 35%

by volume. Less than 30% is preferred.

• PAH (polycyclic aromatic hydrocarbons) content

should be below 10% by volume.

• Metal content of Na, Mg, Si, and Al should be

equal to or lower than 1 mass ppm. (Test
analysis method JPI-5S-44-95)

• Lubricity: Wear mark of WS1.4 should be Max.

Bio-Diesel Fuels

In Europe and in the United States, as well as
some other countries, non-mineral oil based fuel
resources such as RME (Rapeseed Methyl Ester)
and SOME (Soybean Methyl Ester), collectively
known as FAME (Fatty Acid Methyl Esters), are
being used as extenders for mineral oil derived
diesel fuels.

Yanmar approves the use of bio-diesel fuels that
do not exceed a blend of 5% (by volume) of
FAME with 95% (by volume) of approved mineral
oil derived diesel fuel. Such bio-diesel fuels are
known in the marketplace as B5 diesel fuels.

These B5 diesel fuels must meet certain
requirements.

1. The bio-fuels must meet the minimum

specifications for the country in which they
are used.

• In Europe, bio-diesel fuels must comply with

the European Standard EN14214.

• In the United States, bio-diesel fuels must

comply with the American Standard ASTM
D-6751.

2. Bio-fuels should be purchased only from

recognized and authorized diesel fuel
suppliers.

Precautions and concerns regarding the use
of bio-fuels:

1. Free methanol in FAME may result in

corrosion of aluminum and zinc FIE
components.

2. Free water in FAME may result in plugging of

fuel filters and increased bacterial growth.
