STARTING

BATTERIES

EXHAUST

SYSTEM

The

engine

is

equipped

with

a

12

starter.

Prompt

starting

requires

sufficient

battery

capacity

and

battery

cable

size.

Neither

cranking

mance

nor

starter

service

life

will

be

satisfactory

with

an

undersized

battery.

Regular,

monthly

maintenance

of

batteries

may

be

required.

See

Periodic

Maintenance

and

any

instructions

available

from

the

equipment

or

battery

manufacturer.

It

should

be

noted

that

as

long

as

the

equipment

is

operated

regularly,

the

automatic

bat¬

tery

recharging

system

on

the

engine

should

be

able

to

maintain

battery

charge.

See

OUT-OF-SER-

for

prolonged

periods.

EXHAUST

DEADLY!

Mobile

engine-pow¬

equipment

must

never

be

operated

inside

buildings

or

other

enclosed

spaces

without

ample

fresh

air

ventilation.

Stationary

engine-powered

equipment

installed

in¬

side

buildings

or

other

enclosed

spaces

must

be

equipped

with

a

leak-free

exhaust

system

that

car¬

exhaust

gases

to

the

outside,

well

away

from

all

windows,

doors,

vents

and

other

openings

into

the

building

or

enclosure.

It

is

the

responsibility

of

the

equipment

operator(s)

to

check

for

exhaust

leaks

on

a

daily

basis

and

to

have

all

leaks

repaired

before

continuing

metal

parts,

which

is

essentia!

for

top

engine

perfor¬

mance.

For

controlled

engine

break-in:

1.

Operate

the

equipment

as

it

is

intended

to

be

operated.

However,

for

the

first

3

hours,

if

pos¬

sible,

operate

the

equipment

at

about

half

the

available

engine

power,

occasionally

operating

at

full

engine

power

for

brief

periods.

Also,

if

possible,

avoid

prolonged

low-speed,

low-pow¬

er

operation

during

engine

break-in.

2.

Proper

engine

oil

is

especially

critical

during

break-in

because

of

the

higher

engine

temper¬

atures

that

can

be

expected.

See

REC¬

OMMENDED

ENGINE

OIL

in

Introduction.

Change

the

oil

if

it

is

not

appropriate

for

the

am¬

bient

temperatures

during

the

break-in

period.

See

Table

1.

3.

Check

the

oil

level

twice

a

day

or

after

every

4

hours

of

operation

during

the

first

24

hours

of

operation.

4.

Change

the

oil

and

oil

filter

after

the

first

24

hours

of

operation.

5.

See

Table

2

for

engine

models

which

require

valve

clearance

adjustment

after

the

first

50

hours

of

operation.

OPERATION

IN

DUSTY

CONDITIONS

1.

Keep

the

engine

cooling

fins

and

flywheel

air

in¬

let

screen

clean.

2.

Perform

air

cleaner

maintenance

more

often

than

normal—as

required.

See

Table

2.

3.

Change

the

engine

oil

and

oil

filter

more

often

than

normal.

See

Table

2.

Pay

particular

attention

to

the

following

items

when

operating

the

engine

in

temperatures

above

100°

F

(38°

C):

1.

Keep

the

flywheel

air

inlet

screen

and

cylinder

cooling

fins

clean.

See

to

it

that

nothing

ob¬

structs

air

flow

to

and

from

the

engine.

2.

Check

the

oil

level

more

frequently.

3.

Change

the

oil

and

oil

filter

more

often

than

nor¬

mal.

See

Table

2.

4.

Make

sure

the

engine

oil

viscosity

is

appropri¬

ate

for

the

ambient

temperatures

and

change

the

oii

if

necessary.

See

Table

1.

OPERATION

IN

COLD

WEATHER

Pay

particular

attention

to

the

following

items

when

operating

the

engine

in

temperatures

below

freez¬

ing:

1.

M

ake

sure

the

engine

oil

viscosity

is

appropri¬

ate

for

the

ambient

temperatures

and

change

the

oil

if

necessary.

See

Table

1.

If

the

tempera¬

ture

drops

before

you

have

the

chance

to

change

the

oil,

warm

up

the

engine

by

moving

the

equipment

into

a

heated

space

before

at¬

tempting

to

start

the

engine

or

change

oil.

I

Awarning

I

EXHAUST

GAS

IS

DEADLY!

Never

operate

mobile

engine-powered

equipment

indoors

without

ample

fresh

air

ventilation.

2.

Use

fresh

gasoline

and

fill

the

fuel

tank

after

each

day’s

use

to

reduce

problems

with

mois¬

ture

condensation

if

this

is

a

gasoline

engine.

3.

Keep

the

battery

in

a

well-charged

condition.

4.

A

fter

each

use

push

the

equipment

throttle

knob

or

lever

to

the

middle

of

its

speed

range

so

that

if

ice

forms

on

the

linkage

during

storage

it

will

be

easier

to

start

the

engine.

OUT-OF-SERVICE

PROTECTION

Protect

an

engine

that

will

be

out

of

service

for

more

than

30

days

as

follows:

5.

Clean

the

governor

linkage

and

wrap

it

with

a

clean

doth

for

protection.

6.

Plug

the

exhaust

outlet

to

prevent

moisture,

dirt,

bugs,

etc.

from

entering.

7.

Provide

a

suitable

cover

for

the

entire

unit.

1.

R

un

the

engine

until

it

reaches

norma!

operat¬

ing

temperature,

shut

off

the

fuel

supply

and

let

the

engine

run

until

it

stops.

Also,

if

the

equip¬

ment

will

not

be

operated

for

more

than

120

days,

add

a

fuel

preservative

(OnaFresh

™

)

to

the

equipment

fuel

tank

(gasoiine

engines

only).

Follow

the

instructions

on

the

container

label.

Unless

a

preservative

(stabilizer)

is

add¬

ed,

the

gasoiine

will

deteriorate

causing

fuel

system

corrosion,

gum

formation

and

varnish¬

like

deposits

which

can

lead

to

hard

starting

and

rough

operation.

[Awarning]

Gasoline

preservatives

(stabi¬

lizers)

are

toxic.

Follow

the

instructions

on

the

container

label.

Avoid

skin

contact.

Wash

your

hands

with

soap

and

water

after

dispensing

the

fluid.

2.

Drain

the

oil

from

the

engine

while

it

is

still

warm.

Refill

with

fresh

oil

and

attach

a

tag

stat¬

ing

the

viscosity

of

the

oil

used.

3.

Remove

the

spark

plugs

and

squirt

1

ounce

(2

tablespoons

or

28

grams)

of

rust

inhibitor

or

SAE

30

oil

into

each

cylinder.

Crank

the

engine

over

a

few

times

and

reinstall

the

spark

plugs.

4.

Perform

air

cleaner

maintenance

as

instructed

in

Periodic

Maintenance.

.

If

so

equipped,

disconnect

the

battery

(nega¬

tive

[-]

cable

first)

and

follow

the

battery

or

equipment

manufacturer’s

storage

instruc¬

tions.

1.

Remove

the

cover

and

all

protective

wrapping

and

the

plug

from

the

exhaust

outlet.

2.

Check

the

tag

on

the

oil

base.

Change

the

oil

if

the

viscosity

is

not

appropriate

for

the

expected

ambient

temperatures.

See

Table

1.

;heck

the

fuel

filter

and

fuel

Sines

to

make

sure

^

\

§

Check

to

see

that

the

choke,

throttle

and

gover¬

nor

linkages

move

freely.

5.

If

so

equipped,

clean

and

check

the

batten/

ac¬

cording

to

the

battery

or

equipment

manufac¬

turer's

instructions

and

connect

the

battery

cables

(positive

[+]

cable

first).

6

.

Start

the

engine.

T

he

initial

startup

may

be

slow

and

there

may

be

smoke

and

rough

operation

for

a

few

minutes

until

the

oil

in

the

cylinder

burns

off.

If

the

engine

does

not

start,

clean

or

replace

the

spark

plugs

as

they

may

have

been

fouled

by

the

oil

added

to

the

cylinder

when

the

equipment

was

stored.
