SHARPENING

THE

CHAIN

Remember

to

wear

your

gloves!

A

sharp

chain

wil

l

make

your

cutting

chores

much

easier.

The

wood

chips

your

saw

makes

should

be

about

the

size

of

the

teeth

of

the

chain.

If,

instead

they

are

small

and

powdery,

the

chain

is

dull

and

needs

sharpening.

When

the

chain

is

cutting

well,

light

pressure

should

be

enough.

If

you

have

to

force

the

saw

through

the

cut

with

heavy

pressure

or

if

the

saw

cuts

to

one

side,

the

chain

is

dull

or

the

guide

bar

worn

or

both.

1.

Adjust

the

tension

as

tightly

as

you

can

and

still

be

able

to

move

the

chain

around

the

bar.

Place

guide

bar

in

a

vise,

clamping

the

center

of

the

bar.

FILE

IN

ONE

DIRECTION

ONLY

2.

Sharpen

all

the

cutting

edges

on

one

side

first.

Then

sharpen

the

cutting

edges

on

the

other

side.

Mark

your

starting

point

so

you

will

know

when

you

have

finished.

File

in

1

direction

only

—

2

or

3

strokes

per

cutting

edge

is

sufficient.

Your

GAUGE

3.

After

sharpening

the

cutting

edges,

place

the

gaugit

over

the

depth

gauge.

If

the

depth

gauge

sticks

out,

file

it

off

with

the

flat

file.

Do

this

for

each

depth

gauge.

Your

chain

should

now

be

sharp.

Wear

your

gloves.

Work

in

a

lighted

area

with

chain

cooled

off.

A

worn

guide

bar

will

damage

the

chain

and

make

cutting

harder.

Check

the

underside

of

the

chain

for

wear

which

could

be

causing

wear

to

the

guide

bar.

A

lack

of

OIL

in

the

chain

oil

tank

can

damage

both

the

chain

and

the

bar.

Make

sure

there

is

oil

in

the

tank

and

that

you

have

proper

tension

on

the

chain.

Improper

tension

will

also

cause

excessive

wear

to

guide

bar.

The

figure

on

the

left

shows

a

cross-section

of

the

guide

bar

groove.

Check

the

tip

and

rails

of

the

guide

bar

often

for

wear.

If

the

inside

groove

of

the

guide

bar

rail

or

nose

is

worn

replace

the

guide

bar.
