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

 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.

 DANGER

CRUSH HAZARD!

• When you need to transport an engine 

for repair, have a helper assist you to 
attach it to a hoist and load it on a 
truck.

• NEVER stand under a hoisted engine. 

If the hoist mechanism fails, the 
engine will fall on you, causing serious 
injury or death.

• 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!

• 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.

• When you remove any fuel system 

component to perform maintenance 
(such as changing the fuel filter) place 
an approved container under the 
opening to catch the fuel.

• NEVER use a shop rag to catch the 

fuel. Vapors from the rag are extremely 
flammable and explosive.

• Wipe up any spills immediately.

• Wear eye protection. The fuel system 

is under pressure and fuel could spray 
out when you remove any fuel system 
component.

• Failure to comply will 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.

 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.

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.

allow battery fluid to come in contact 
with clothing, skin or eyes. Severe 
burns could result. ALWAYS wear 
safety goggles and protective clothing 
when servicing the battery. If contact 
with the skin and / or eyes should

 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.
