ENGINE OPERATION

LV Operation Manual

DANGER

FIRE AND EXPLOSION HAZARD!

• Only use the key switch to start the

engine.

• NEVER jump start the engine. Sparks

caused by jumping the battery to the
starter terminals may cause a fire or
explosion.

• 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.

• NEVER remove the fuel cap with the

engine running.

• 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.

• Only fill the fuel tank with diesel fuel.

Filling the fuel tank with gasoline may
result in a fire.

• NEVER refuel with the engine running.

• Wipe up all spills immediately.

• Keep sparks, open flames or any other

form of ignition (match, cigarette,
static electric source) away when
fueling / refueling.

• NEVER overfill the fuel tank.

• Fill the fuel tank and store fuel in a

well-ventilated area only.

• 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.

• 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

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

SEVER HAZARD!

• Keep hands and other body parts

away from moving / rotating parts
such as the cooling fan / flywheel.

• Wear tight fitting clothing and keep

your hair short or tie it back while the
engine is running.

• Remove all jewelry before you operate

or service the machine.

• NEVER start the engine in gear.

Sudden movement of the engine
and / or machine could cause death or
serious personal injury.

• NEVER operate the engine without the

guards in place.

• Before you start the engine make sure

that all bystanders are clear of the
area.

• Keep children and pets away while the

engine is operating.

• Check before starting the engine that

any tools or shop rags used during
maintenance have been removed from
the area.

• Failure to comply could result in death

or serious injury.

WARNING

EXHAUST HAZARD!

• NEVER operate the engine in an

enclosed area such as a garage,
tunnel, underground room, manhole or
ship’s hold without proper ventilation.

• NEVER block windows, vents, or other

means of ventilation if the engine is
operating in an enclosed area. All
internal combustion engines create
carbon monoxide gas during
operation. Accumulation of this gas
within an enclosure could cause
illness or even death.

• Make sure that all connections are

tightened to specifications after repair
is made to the exhaust system.

• Failure to comply could result in death

or serious injury.

0000003en

WARNING

ALCOHOL AND DRUG HAZARD!

• NEVER operate the engine while you

are under the influence of alcohol or
drugs.

• NEVER operate the engine when you

are feeling ill.

• Failure to comply could result in death

or serious injury.

WARNING

EXPOSURE HAZARD!

• Wear personal protective equipment

such as gloves, work shoes, eye and
hearing protection as required by the
task at hand.

• NEVER wear jewelry, unbuttoned

cuffs, ties or loose fitting clothing
when you are working near
moving / rotating parts such as the
cooling fan, flywheel or PTO shaft.

• ALWAYS tie long hair back when you

are working near moving / rotating
parts such as a cooling fan, flywheel,
or PTO shaft.

• NEVER operate the engine while

wearing a headset to listen to music or
radio because it will be difficult to hear
the warning signals.

• Failure to comply could result in death

or serious injury.

0000005en

CAUTION

NEVER use an engine starting aid such
as ether. Engine damage will result.

0000009en

CAUTION

For maximum engine life, Yanmar

recommends that when shutting the
engine down, you allow the engine to
idle, without load, for 5 minutes. This
will allow the engine components that
operate at high temperatures, such as
the turbocharger (if equipped) and
exhaust system, to cool slightly before
the engine itself is shut down.

0000008en

CAUTION

Make sure the engine is installed on a
level surface. If a continuously running
engine is installed at an angle greater
than 20° (in any direction) or if an engine
runs for short periods of time (less than
3 minutes) at an angle greater than 25°
in any direction, engine oil may enter the
combustion chamber causing exessive
engine speed and generate white
smoke. This may cause serious engine
damage.

0000010enTNE

CAUTION

New Engine Break In:

• On the initial engine start-up, allow the

engine to idle for approximately 15
minutes while you check for proper
engine oil pressure, diesel fuel leaks,
engine oil leaks, coolant leaks, and for
proper operation of the indicators
and / or gauges.

• During the first hour of operation, vary

the engine speed and the load on the
engine. Short periods of maximum
engine speed and load are desirable.
Avoid prolonged operation at
minimum or maximum engine speeds
and loads for the next 4 to 5 hours.

• During the break-in period, carefully

observe the engine oil pressure and
engine temperature.

• During the break-in period, check the

engine oil and coolant levels
frequently.

0000011en

CAUTION

NEVER hold the key in the START
position for longer than 15 seconds or
the starter motor will overheat.
