6JH Series Operation Manual
SAFETY PRECAUTIONS
General Information
There is no substitute for common sense
and careful practices. Improper practices
or carelessness can cause burns, cuts,
mutilation, asphyxiation, other bodily injury
or death. This information contains general
safety precautions and guidelines that
must be followed to reduce risk to personal
safety. Special safety precautions are
listed in specific procedures. Read and
understand all of the safety precautions
before operation or performing repairs or
maintenance.
Before You Operate
DANGER
The safety messages that follow have
DANGER level hazards.
NEVER permit anyone to
install or operate the engine
without proper training.
Read and understand this
Operation Manual before you operate or
service the engine to ensure that you
follow safe operating practices and
maintenance procedures.
• Safety signs and labels are additional
reminders for safe operating and
maintenance techniques.
•See your authorized Yanmar Marine
dealer or distributor for additional
training.
During Operation and
Maintenance
WARNING
The safety messages that follow have
WARNING level hazards.
Explosion Hazard
While the engine is running
or the battery is charging,
hydrogen gas is being
produced and can be easily
ignited. Keep the area
around the battery
well-ventilated and keep sparks, open
flames and any other form of ignition
out of the area.
Fire and Explosion Hazard
Diesel fuel is flammable and explosive
under certain conditions.
NEVER use a shop rag to catch the fuel.
Wipe up all spills immediately.
NEVER refuel with the engine running.
Fire Hazard
Undersized wiring systems
can cause an electrical fire.
Store any containers containing fuel or
other flammable products in a
well-ventilated area, away from any
combustibles or source of ignition.
Store any equipment in a designated
area away from moving parts.
NEVER use the engine compartment for
storage.

SAFETY
JH Series Operation Manual 7
12/05
WARNING
Sever Hazard
Rotating parts can cause
severe injury or death.
NEVER wear jewelry,
unbuttoned cuffs, ties or
loose-fitting clothing and
ALWAYS tie long hair back when
working near moving / rotating parts
such as the flywheel or PTO shaft. Keep
hands, feet and tools away from all
moving parts.
Alcohol and Drug Hazard
NEVER operate the engine
while under the influence of
alcohol or drugs, or when
feeling ill.
Exposure Hazard
ALWAYS wear personal
protective equipment
including appropriate
clothing, gloves, work
shoes, and eye and hearing protection
as required by the task at hand.
Sudden Movement Hazard
NEVER operate the engine while
wearing a headset to listen to music or
radio because it will be difficult to hear
the warning signals.
Burn Hazard
Some of the engine
surfaces become very hot
during operation and
shortly after shutdown.
Keep hands and other body
parts away from hot engine surfaces.
Exhaust Hazard
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 and special precautions are
required to avoid carbon monoxide
poisoning.

SAFETY
8JH Series Operation Manual
CAUTION
The safety messages that follow have
CAUTION level hazards.
Poor Lighting Hazard
Ensure that the work area is adequately
illuminated. ALWAYS install wire cages
on portable safety lamps.
To o l H a z a rd
ALWAYS use tools appropriate for the
task at hand and use the correct size
tool for loosening or tightening
machine parts.
Flying Object Hazard
ALWAYS wear eye protection when
servicing the engine or when using
compressed air or high-pressure water.
Dust, flying debris, compressed air,
pressurized water or steam may injure
your eyes.
Coolant Hazard
Wear eye protection and
rubber gloves when you
handle engine coolant. If
contact with the eyes or skin should
occur, flush eyes and wash immediately
with clean water.
NOTICE
The safety messages that follow have
NOTICE level hazards.
It is important to perform daily checks as
listed in the Operation Manual. Periodic
maintenance prevents unexpected
downtime, reduces the number of
accidents due to poor engine performance
and helps extend the life of the engine.
See your authorized Yanmar Marine dealer
or distributor if you need to operate the
engine at high altitudes. At high altitudes
the engine will lose power, run rough and
produce exhaust gases that exceed the
design specifications.
ALWAYS be environmentally
responsible.
Follow the guidelines of the
EPA or other governmental
agencies for the proper disposal of
hazardous materials such as engine oil,
diesel fuel and engine coolant. Consult the
local authorities or reclamation facility.
NEVER dispose of hazardous materials by
dumping them into a sewer, on the ground,
or into ground water or waterways.
If a Yanmar Marine Engine is installed at
an angle that exceeds the specifications
stated in the Yanmar Marine Installation
Manuals, engine oil may enter the
combustion chamber causing excessive
engine speed, white exhaust smoke and
serious engine damage. This applies to
engines that run continuously or those that
run for short periods of time.

SAFETY
JH Series Operation Manual 9
12/05
NOTICE
If you have an installation with two or three
engines and only one engine is operating,
the water pickup (thru-hull) of the
non-running engine(s) should be closed.
This will prevent water from being forced
past the seawater pump and eventually
finding its way into the engine. The result
of water entering the engine could cause
seizure or other serious problems.
If you have an installation with two or three
engines, and only one engine is operating,
please note that if the propeller shaft
thru-hull (stuffing box) is lubricated by
engine water pressure and the engines are
interconnected, care must be taken that
water from the running engine does not
enter the exhaust of the non-running
engine(s). This water could cause seizure
of the non-running engine(s). See your
authorized Yanmar Marine dealer or
distributor for a complete explanation of
this condition.
If you have an installation with two or three
engines, and only one engine is operating,
it is important to limit the amount of throttle
applied to the running engine. If you
observe black smoke or movement of the
throttle does not increase engine speed,
you are overloading the engine that is
running. Immediately throttle back to
approximately 2/3 throttle or to a setting
where the engine performs normally.
Failure to do so may cause the running
engine to overheat or cause excess carbon
buildup which may shorten the engine’s
life.
NEVER turn off the battery switch (if
equipped) or short the battery cables
during operation. Damage to the electrical
system will result.
