1. For your safety

1.1 WARNING

SYMB

OLS

Most

operation, maintenance and inspection problems arise due

to

users' failure

to

comply

with

the

rules and precaut1ons

for

safe operation described in this operation

manual. Often, users

do

not

understand

or

recognize the signs

of

approaching problems.

Improper handling can cause burns and other injuries and can result in death.

Be

sure

to

read this operation manual carefully before operating

the

engine and observe

all

of

the instructions and precautions described in this manual.

Below follow the warning signs used in this manual. Pay special attention

to

parts

containing these

words

and signs.

A DANGER DANGER indicates an imminently hazardous

situation which,

if

not

avoided, WILL result in death

or

serious injury.

A WARNING WARNING indicates a potentially hazardous situa-

tion which,

if

not

avoided, COULD result

in

death

or

serious injury.

A CAUTION CAUTION indicates a potentially hazardous situa-

tion which,

if

not

avoided,

may

result in

minor

or

moderate injury.

' This sign is also

be

safety

A DANGER

A WARNING

A CAUTION

I

Ba

tt

ery

Never smoke

or

permit sparks near the battery, because

it

may emit

explosive hydrogen gas. Place the battery in a well-ventilated place.

Fuel

Use only diesel oil. Never use other fuel

s,

including gasoline, kerosene,

etc., because they could cause a fire. The wrong fuel could also cause

the fuel injection

pump

and injector

to

fail due to lack

of

proper

lubrication. Be sure to check that you have selected the correct diesel

fuel before filling the fuel tank.

Fire

Prevention

Be sure

to

stop the engine and confirm that there are no open flames

in the vicinity before supplying fuel. If you

do

spill fuel, wipe such

spillage carefully and dispose

of

the wiping materials properly. Wash

your

hands thorougly with soap and water.

Neverplace oil

or

otherflammable material in the engine room.

Install a fire extinguisher near the engine room, and familiarize yourself

with its use.

Exhaust

Gas

Exhaust gas contains poisonous carbon monoxide and should not be

inhaled.

Be sure

to

install ventilation ports

or

ventilators in the engine room and

ensure

good

ventilation during engine operation.

Moving

Part

s

Do

not

touch

or

let your clothing

get

caught in the moving parts

of

the

engine, such as the front drive shaft, V-belt

or

propeller shaft, during

engine operation. You will be injured.

Neveroperate t

he

engine without the covers on the moving parts.

Burns

The whole engine is hot during operation and immediately after

stopping. The exhaust manifold, exhaust pipe and high pressure fuel

pipe are very hot. Never touch these parts with your

body

or

clothing.

of

:

the

instrume

panel, which is connected

by

wire harness; the remote control handle, which is

hooked

up

by remote control cable to each of the engine control levers, and the stopping

equipment.

The handle controls the course

of

the boat

(ahead

acts as

an

accelerator increasing the

engine speed as it is pushed further

in

the

FWD

direction.

If

the handle is

pulled out, engine speed can be controlled

without engaging the clutch (clutch

Handling

of

Fuel Oil

1)

Water and dust in the fuel cause engine

failure. When fuel is

sto

red, be sure that

the inside

of

the storage container is

clean, and that the fuel is stored away

from dirt

or

rain water.

2)

Keep the fuel container stationery for

several hours

to

allow any dirt

or

water

to

settle

to

the bottom. Use a

pump

to

extract the clear, filtered fuel from the

top

of

the container

for

use.

Use

the clear filtered fuel from the upper

middle section of the container only, leaving any

contaminated fuel at

the

bottom.
