hazard

or unsafe

practice

which can resuh in

personal

injury or

equipment damage.
Fuels, electrical

equipment,

exhaust

gases,

batteries and

moving

parts

have

potential

hazards that

could

result

in

serious

personal

injury. Care must

be taken

as to the

following

items:

Gasollne ls

DANGEROUS

Use extreme

caution around

gasoline

because

a

potential

for explosion

or

fire

exists at all times.

Never use

open

flame or sparks near

gasoline.

Never

fill the fuel

tank near the

generator

set
while the engine is running.
Install flexible section, e.g.

flexible tubes or hoses

(SAE

J30b-1973) to the

fuel

line

between the

generator

set and the fuel

tank, where vibrations
must be absorbed.
Gasoline is more dangerous when it

is in a

vaporous

state, mixed with air at a

certain

ratio,

than when it

is

in a liquid

state.

Securely

close

the lid of a

gasoline

container.

Wipe off any spilt

gasoline

immediately and

thoroughly. Never

start

the engine when

the area

is wet with

gasoline.

.

Always have a fire extinguisher

nearby. Ensure

that

the

extinguisher

is

properly

maintained and

be

familiar

with

its

proper

use so

you

can use it

effectively

in an emergency. E).tinguishers rated

ABC by

the

NFPA are suitable for oils, electrical

and

general

use.

Consult

the

local fire

department

for

the correct type of extinguisher

for various applications.

RECOMMENOED

vtscoslrY
(sAE)

UNLEADED GASOLINE

The

quality

of

gasoline

engine oil bears close

relationship

to

the

engine

performance

and

life.

The

use

of a

poor

grade

oil or an oil

having

viscosity not

suited

to

your

climate may cause hard

starting and/or

premature

wear due to inadequate

lubrication of

various

components,

even

leading

to engine seizure.

CAUTION

1. When the engine

is

pr.rt

into

operation for

a long

period

of

time, engine oil

properties

are bound to

deteriorate as the engine

oil

is exposed to highly

heated components,

or worn

metal

particles,

carbon, water or dust

gets

into

the

engine oil. lt is,

therefore,

necessary

to change the engine oil

at

regular

intervals,

2. Too low

oil

level not only will

quicken

oil

deterioration, btrt

will

cause

engine

seizure.

So

replenish engine oil as soon as

possible.

3.

Mixing oils of different brands might

deteriorate oil

properties.

Therefore, avoid mixing

engine oils of

different brands.

LONG LIFE

COOLANT

(Year

round

coolant) and Antlfreeze

Solutlon

Selectlon

of

Long

Llfe Coolant & Antlfreeze Solutlon

When

the

cooling water

is

frozen,

there

is

a

possibility

that

the cylinder head or cylinder block,

or

possibly

the

radiator, may

be

broken.

Long

life coolant or

antifreeze is

mixed

with

the cooling

water

to

prevent

freezing.

These solutions come

in two

kinds: Antifreeze is used

only

during a winter

season mainly

for

the

purpose

of

preventing

freezing.

Long

life coolant is used

throughout

the

year

for the

purpose

of

preventing

corrosion of

the

cooling

system, besides

the

prevention

of freezing. Select

'long

life coolant or antifreeze for

aluminum engines'. Use a mixture that is

best

suited

for

your

local

conditions

and temperature.

It

is advisable to use

long

life

coolant having

the

following

features:

1.

Long life

type coolant

in

which

special rust

prohibitive

agents, anticorrosion agents, etc. have

been added

(in

larger amounts than in antifreeze)

to a highly

pure

ethylene

glycol.

The components

of

coolant of this type will hardly

evaporate. Simple

replenishment

of

water

will

maintain the original intended

performance.

'Long

life

coolant

for

aluminum engines'can

protect

aluminum alloys that

do

not

have strong

rust/corrosion-withstanding

properties.

Also,

it can

protect

cast

iron.

Long

life

coolant

prevents

wear

of the water

pump

or water leakage.

CAUTION

Be

sure to

use

tap water to dilute long life

coolant

or antifreeze.

Keep

the concentration of long life coolant or

antifreeze at

a level matched with the lowest

temperature in

your

local

region.

3. Mixing of

long

life coolant or antifreeze

of different

brands might deteriorate its

properties.

Therefore,

avoid

mixing solutions

of

different

brands.

4. Using

100%

of undiluted solution does

not always

ensure

the

safety

of

your

engine. ln a very cold

climate,

100%

antifreeze or

long

life

coolant

can

treeze

and

cause damage.

5. The use of a

poor grade

antifreeze

may

cause

damage

to

the engine and

radiator.

The

use

of long

life coolant or antifreeze for cast iron engines may

cause

damage to aluminum, copper,

etc.

6. Long life coolant

or

antifreeze

is

poisonous.

Be sure

to

keep it in the original container and always store

it

in a

place

where

children

can

not reach.

LEAD BATTERY ELECTROLYTE
A

mixing

solution of sulfuric acid

and

distilled

water

is

used

as the battery

electrolyte.

Normally, the battery

electrolyte

is

a diluted sulfuric acid having

such

a

concentration that its specific

gravity

becomes 1.26 at

a

solution

temperature

of 20"C

(68'F)

in a fully

charged

state.

When

over-charged, the water

component

of

the

battery

electrolyte is

prone

to

evaporate.

lf the battery is operated continually with the

electrolyte

level too low, it will no longer be

possible

to store

electricity. Add water to compensate for the

evaporated

water.

-

WARNING

-

.

Never

permit

any fire to be brought

near

the battery.

CAUTION

USE DIST]LLED

WATER OR

DRINKING WATER

in

water replenlshment for lhe batlery efectrolyle.

In

each

cell,

add water up to

the

'UPPER'

level.
