Service

life

of

your

engine

is

dependent

on

how

your

engine

is

operated

and

serviced

during

initial

hours

of

operation.

Your

new

engine

needs

approximately

fifty

e)

A

The

While

it

is

unlikely

that

the

operator

will

be

forced

to

the

does

exist.

Therefore,

it

is

recommended

that

be

carried

adjustment

are

the

only

adjustments

the

ser

vicing

dealer

can

perform

on

the

injection

pump.

Other

types

of

adjustments

or

repairs

must

be

performed

by

a

qualified

inject

service

shop.

To

obtain

long

and

satisfactory

service

life

from

of

your

injec~

tion

pump:

1.

Always

use

the

correct

grade

fuel

-

*2

Diesel.

2.

Filter

the

fuel

to

remove

any

water

or

impurities.

3.

Clean

and

renew

the

fuel

filters

regularly.

COOLING

SYSTEM

L

CooH

Water

As

cooling

water,

use

soft

water

th

few

impurities

such

as

tap

water

(potable

water)

or

rainwater.

Never

use

hard

water

or

foul

water.

Use

of

hard

water

or

water

containing

much

impurity

will

lead

to

collection

of

scale

in

the

engine

and

heat

exchanger

with

resultant

decline

in

cooling

efficiency.

2.

Antifreeze

It

is

recommended

that

a

freshwater

and

antifreeze

xture

be

used

year

round.

Use

an

antifreeze

that

is

compatible

with

aluminum

cooling

system

components.

Keep

mind

that

water

when

it

freezes

expands

to

break

the

engine

heat

exchanger

and

the

engine

block.

So

maintain

an

antifreeze

mixture

in

the

cooling

system

year

round.

Do

not

be

caught

short.

*Antifreeze

of

po?r

quality

or

without

rust

inhibitor

will

cause

corrOSlon

of

the

cooling

system.

Always

use

antifreeze

prepared

by

a

reliable

maker.

Never

use

it

mixed

with

antitreeze

of

a

different

brand.

*Make

sure

that

the

cooling

system

of

the

engine

is

cleaned

well

before

adding

antifreeze.

*Recommended

antifreeze

for

year

round

use

is

ZEREX

or

PRESTONE

with

rust

inhibitor

.

•

Mix

the

antifreeze

and

fresh

water

thoroughly

before

adding

it

to

the

cooling

system.
