of

your

O

Keep

—

Even

a

is

unsafe

and

will

cause

excessive

wear

to

parts.

O

Don't

Force

Saw

Out

of

—

Use

don't

force

O

Wood

—

The

chips

should

be

about

the

size

of

the

chain

teeth.

If

they

are

small

and

powder

like,

your

chain

is

dull.

Get

it

Sharpened!

O

Don't

Press

Hard

—

Light

pressure

is

enough.

Heavy

pressure

can

CAUTION:

When

preparing

Do

not

use

fuel

mixture

that

has

been

stored

longer

than

two

(2)

months.

Fuel

mixture

stored

longer

than

this

will

cause

and

poor

performance

of

your

saw.

If

fuel

mix

has

been

stored

in

your

longer

than

this

time

it

OILING

1.

Fill

the

oil

tank

each

time

you

fill

the

fuel

tank.

Lack

of

will

quickly

ruin

the

bar

and

2.

You

will

use

at

least

1/3

tank

of

oil

for

each

tank

of

gas.

If

you

use

less,

check

for

a

plugged

oil

hole

in

the

guide

bar.

Use

clean

oil.

Do

not

let

sawdust

or

dirt

into

the

oil

tank.

Clean

the

oil

cap

and

the

area

around

it

before

removing.

A

little

oil

will

pump

out

after

the

engine

stops.

Oil

on

the

Read

the

safety

in

the

front

of

this

manual.

Always

keep

your

chain

sharp.

Plan

Ahead

Check

The

Wind

—

If

it

is

strong

enough

to

move

the

top

of

the

tree,

DON

T

CUT!

Come

back

another

day!

Check

The

Lean—Tie

a

weight

to

a

piece

of

string

about

3

feet

long.

Hang

the

weight

in

your

line

of

sight.

The

string

is

a

good

vertical

line

to

help

you

judge

the

lean

of

the

tree.

The

tree

will

try

to

fall

the

way

it

is

leaning.

Check

The

Weight

Distribution

—

A

tree

is

heavier

on

the

side

with

the

most

limbs.

It

will

try

to

fall

on

its

heavy

side.

Trim

a

few

limbs

to

"balance"

the

tree.

Clear

The

Work

Area

—

You

need

a

clean

area

all

around

the

tree

for

good

footing.

Get

everything

out

of

the

area

where

the

tree

will

fall.

People,

pets,

cars,

etc.

Find

a

Retreat

Path

—

Know

which

way

you

are

going

when

the

tree

starts

to

fall.

Make

sure

it

is

clear.

CARE

AND

MAINTENANCE

FOR

YOUR

SAW

Follow

these

helpful

hints

on

care

and

maintenance

to

get

the

best

possible

service

from

your

saw,

to

prevent

major

break¬

down

and

costly

repair

bills.

Careful

servicing

of

your

saw

is

one

of

the

most

important

steps

in

preventative

maintenance.

Should

your

saw

develop

trouble

that

you

are

not

prepared

to

handle,

take

it

to

an

authorized

Service

Dealer

for

service.

He

has

been

trained

and

is

equipped

to

provide

expert

service

work.

CLEANING:

Protect

your

investment.

Keep

your

saw

clean

and

free

of

saw

dust,

dirt,

etc.

Clean

cylinder

fins

regularly.

HANDLING:

Your

saw

is

a

precision

built

tool.

Do

not

abuse

it

by

rough

handling.

Do

not

leave

it

out

in

the

weather,

unpro¬

tected.

When

transporting

your

saw

by

truck

or

car,

make

cer¬

tain

that

it

is

secured

in

place

so

as

not

to

be

tossed

around.

INSPECTION:

After

each

use,

check

your

saw

for

loose

nuts

and

screws

and

worn

parts.

Have

your

authorized

service

dealer

replace

worn

parts.

Make

certain

that

chain

is

kept

sharp.

If

you

have

any

questions

regarding

the

operational

condition

of

your

saw,

have

your

authorized

service

dealer

examine

it.

SPARK

PLUG:

Remove

spark

plug

and

clean.

If

plug

is

fouled,

replace

with

a

new

one.

Measure

the

gap

with

a

wire

gauge.

Gap

should

be

set

at

.025

inch.

AIR

FILTER:

The

air

filter

is

located

under

the

air

filter

cover

just

behind

the

gas

tank.

Remove

and

lift

out

air

filter.

Clean

the

air

filter

by

sloshing

it

around

in

clean

gasoline

or

a

clean¬

ing

solvent.

Allow

filter

to

dry

and

then

replace.

Clean

the

air

filter

after

every

10

tanks

of

gas

or

every

5

hours

of

operation.

Caution:

Never

operate

your

saw

without

the

air

filter

in

place

as

dirt

and

dust

in

the

air

can

be

sucked

up

through

the

car¬

buretor

and

into

the

combustion

chamber

causing

excessive

wear

to

piston

rings

and

cylinder

wall.

Always

keep

an

extra

air

filter

on

hand.

FUEL

PICK-UP

FILTER:

The

fuel

pickup

filter

is

located

in¬

side

the

gas

tank

at

the

end

of

the

fuel

pickup

line.

Should

the

filter

become

loaded

with

dirt

or

water

logged,

it

will

not

filter

the

fuel

properly

and

should

be

replaced.

To

replace

the

pick¬

up

filter,

remove

the

gas

tank

cover

to

expose

the

gas

pickup

line

and

filter.

Remove

old

filter

and

replace

with

new

one.

Caution:

Never

operate

your

saw

without

the

fuel

pickup

filter

in

place.

CYLINDER

FINS:

It

is

important

that

the

cylinder

fins

be

kept

clean

to

insure

proper

cooling

and

a

good

flow

of

air

over

the

cylinder.

If

cylinder

fins

are

not

cleaned,

intense

heat

will

build

up

in

the

engine

and

cause

severe

damage

to

it.

To

clean

cylinder

fins,

remove

fan

housing

and

use

compressed

air

to

blow

away

the

dirt,

sawdust,

etc.

from

between

the

fins.

If

compressed

air

is

not

available,

use

a

small

brush

soaked

in

a

cleaning

solvent

or

gasoline.

To

clean

the

muffler

screen,

remove

the

muffler

baffle

and

two

studs

holding

muffler

body

and

screen.

Clean

screen

with

a

wire

brush.

While

check

for

exhaust

ports.

Exhaust

ports

that

are

clogged

with

carbon

will

cause

your

engine

to

loose

power.

Make

cer¬

tain

that

ports

are

open.

To

clean

exhaust

ports

follow

these

directions:

1.

Remove

openings.

3.

Scrape

the

carbon

from

the

exhaust

ports

until

ports

are

completely

open.

Be

extremely

careful

not

to

mar

the

pis¬

ton.

Use

wooden

scraper

only.

4.

Blow

away

the

loosened

carbon

particles

with

compressed

air.

If

compressed

air

is

not

available,

turn

saw

on

its

side

and

shake

out

the

particles.

STORING

THE

SAW

Once

you

have

finished

using

the

saw

and

it

is

to

be

idle

for

several

months,

follow

these

steps

before

storing

the

saw.

1.

Drain

fuel

from

fuel

tank.

2.

Start

engine

and

allow

to

run

at

idle

speed

until

all

fuel

is

used.

3.

Drain

oil

from

oil

reservoir.

4.

Store

the

may

also
