This

chain

was

designed

so

that

80%

of

the

needed

sharpening

is

accomplished

by

the

saw's

built-in

sharpener.

While

the

chain

is

being

sharpened

by

the

built-in

sharp-

ener,

the

cutting

edges

of

the

chain

are

gradually

being

altered.

These

edges

may

also

be

damaged

if

you

saw

into

rock,

dirt,

nails,

or

other

foreign

materials.

In

either

case,

it

will

be

necessary

to

reshape

the

side

cutting

edge

with

a

file.

To

properly

file

the

Power

Sharp

Chain

you

will

need

a

fileholder

and

the

correct

size

file.

Follow

these

instruc-

tions:

1.

If

possible,

remove

the

chain

from

the

saw

and

put

it

in

a

saw

chain

filing

vise.

If

you

do

not

have

a

filing

vise,

tension

the

chain

up

snugly

on

the

guide

bar.

Use

a

No.

5595

Fileholder

and

hold

it

level

at

a

24

°

angle

to

the

chain.

Always

file

from

inside

of

chain

toward

the

outside.

2.

When

cutters

have

been

filed

back

to

a

point

where

the

gullet

(see

fig.

A

)

extends

beyond

the

cutting

edge

by

1/16

inch,

the

gullet

should

be

removed.

Do

this

before

your

next

cutting

edge

filing,

using

the

same

7/32

—

file

and

maintaining

the

same

24

°

Top

Plate

Angle.

The

correct

gullet

shape

will

then

be

as

shown.

3.

The

factory

settings

are

.025

The

mark

on

the

depth

gauge

(see

fig.

)

is

for

setting

of

.030

inch.

If

you

wish

to

use

this

setting,

simply

file

off

metal

behind

the

mark

with

a

round

file

as

shown

in

Remember:

(a)

Normal

sharpening

is

accomplished

by

the

built-in

sharpener.

(b)

File

cutters

only

when

dull

and

attempt

to

The

be

the

(see

(c)

Preserve

the

original

filing

carefully

and

uniformly.

(d)

Care

should

be

taken

never

to

file

into

the

bottom

of

the

Top
