HOW

TO CHECK

THE

OIL

NOTE:

Do not check the level of the oil while the

engine

runs.

1.

Make

sure

the

unit

is level.

2.

Clean

the

area

around

the

dipstick

(Figure

24).

Remove

the

dipstick,

Wipe

the

oil from

the

dipstick,

3.

Insert

the

dipstick

into the

oil fill tube.

Turn

the

dipstick

clock-

wise

until

it is tight.

Remove

the

dipstick,

Check

the

oil level

on

the

dipstick.

The

oil level

must

reach

the

FULL

mark

on the

dipstick.

4.

If necessary,

add

oil until

the

oil reaches

the

FULL

mark

on the

dipstick,

The

quantity

of

oil

needed

from

ADD

to

FULL

is

shown

on the

dipstick.

Do

not add

too

much

oil.

Remove

the

oil drain plug.

Drain the oil completely

from the

engine.

Install and tighten the

oil

drain

plug.

Only

use

a

high

quality

detergent

oil

rated

with

API

service

classification

SG, SH,

SJ or SL. Select

the

oil's

SAE

viscosity

grade

according

to the

expected

operating

temperature

using

the

temperature

chart

below:

NOTE:

Synthetic

oil meeting

certifica-

tion

mark

and API

service

symbol

(shown

at left)

with

"S J/

or higher,

is an

acceptable

oil at all temperatures.

HOW

TO CHANGE

THE OIL

NOTE: Do not drain

the

oil

from

a cold

engine.

Before you drain

the oil, let the engine run for several minutes. Make sure you do

not get oil on the belts.

1.

With

the

engine

OFF

but

still warm,

place

the

engine

level

and

disconnect

the

wire

from

the

spark

plug.

*

CAUTION:

Air

cooled

engines

run

hotter

than

automotive

engines.

The use of non-synthetic

multi-viscosity

oils (5W-30,

10W-30, etc.) in temperatures

above 40 ° F (4 ° C) will result in

higher

than

normal

oil

consumption.

When

using

a

multi-viscosity

oil, check oil level more frequently.

**

CAUTION:

SAE 30 oil, if used below 40 ° F (4° C), will result in

hard

starting

and

possible

engine

bore

damage

due

to

inadequate

lubrication.

NOTE:

Although

multi-viscosity

oils

(5W30,

10W30,

etc.)

improve

starting in cold weather, they will result in increased

oil consumption

when used above 320 F. Check the

engine

oil

level more frequently

to avoid

possible

engine

damage

from

running

low on oil.

4.

Clean

the area

around

the

dipstick.

Remove

the

dipstick.

Slowly

pour approximately

48 ounces (3 pints)

of oil into the oil

fill tube.

Insert the

dipstick

into the oil fill tube. Turn the

dipstick

in a

clockwise

direction until it is tight. Remove the dipstick.

Check

the oil level on the dipstick.

The oil level must reach the FULL

mark on the dipstick.

HOW

TO CLEAN

THE

COOLING

SYSTEM

The

engine

is air cooled.

The

air that

cools

the

engine

enters

through

the air

screen

on top

of the

engine.

Clean

the air

screen

every

100

hours

or every

year

as follows.

1.

Remove

any grass, dirt or debris

from the

air screen

with a

cloth or brush (see Figure 24).

2.

Inspect

the edge

of the

engine

shroud

for grass

or debris.

Remove

any grass or debris visible

at the bottom edge of the

engine

shroud.

HOW

TO CHECK

THE

MUFFLER

26

Check

the muffler

every

50 hours.

Make

sure

the

muffler

is correctly

mounted

and

is not

loose.

If the

muffler

is worn

or burnt,

replace

with

a new

muffler.

A worn

muffler

is a fire

hazard

and

can

damage

the

engine.

If you

mount

a spark

arrester

to the

muffler,

also

check

the

spark

arrester

when

you

check

the

muffler.

If the

spark

arrester

is worn

or

damaged,

replace

it with

a new

spark

arrester

purchased

from

a

Sears

Service

Center.
