IMPORTANT

POINTS

TO

REMEMBER

a.

When

puffingthe

starter

rope,

do

not

use

the

full

extent

of

the

rope

as

this

can

cause

the

rope

to

break

Do

not

let

the

starter

rope

snap

back

—

hold

the

handle

and

let

the

rope

rewind

slowly.

b.

If

the

engine

fl

oods,

let

the

unit

sit

for

a

few

minutes,

then

repeat

starting

procedure

using

the

half

—choke

position.

c.

For

cold

weather

starting,

allow

the

engine

to

warm

up.

(1-2

min.)

at

the

half

—choke

position,

then

move

choke

to

the"Off"

Do

not

cut

material

with

at

"Full"

or

"Half"

position.

TYPES

OF

CUTTING

A.

BASIC

CUTTING

TECHNIQUE

1.

IMPORTANT

POINTS

a.

Cut

wood

only.

Do

not

cut

metal;

plastics;

ma-

sonry;

non

—wood

building

materials;

etc.

b.

Stop

the

saw

if

the

chain

strikes

a

foreign

object.

Inspect

the

saw

and

repair

or

replace

marts

as

necessary

c.

Keep

the

chain

out

of

dirt

and

sand.

Even

a

small

amount

of

dirt

will

quickly

dull

a

chain

and

thus

increase

the

possibility

of

kickback.

A

WARNING

Kickback

can

occur

when

the

moving

chain

con-

tacts

an

object

at

the

upper

portion

of

the

tip

of

the

guide

bar

or

when

the

wood

closes

in

and

pinches

the

saw

chain

in

the

cut.

Contact

at

the

upper

por-

tion

of

the

li

p

of

the

guide

bar

can

cause

the

chain

to

dig

into

the

object

and

stop

the

chain

for

an

in-

stant.

The

result

is

a

lightning

fast,

reverse

reac-

tion

which

kicks

the

guide

bar

up

and

back

toward

the

operator

If

the

saw

chain

is

pinched

alongthe

top

of

the

guide

bar

the

guide

bar

can

be

driven

rapidly

back

toward

the

operator.

Either

of

these

reactions

can

cause

loss

of

saw

control

which

can

result

in

serious

injury.

UNDERSTANDING

REACTIVE

FORCES

Pinch

-kickback

and

Pull

-In

occur

when

the

chain

is

suddenly

stopped

by

being

pinched,

caught,

or

by

contacting

a

foreign

object

in

the

wood.

This

stopping

of

the

chain

results

in

a

re-

versal

of

the

chain

force

used

to

cut

wood

and

causes

the

saw

to

move

in

the

opposite

direction

of

chain

ro-

tation.

Either

reaction

can

result

in

loss

of

control

and

possible

serious

injury

•

Pinch

—Kickback--

--

occurs

when

the

chain

on

top

of

the

bar

is

•

Pull

PROCEDURE

Practice

cutting

a

few

small

logs

using

the

following

technique

to

get

the

"feel"

of

using

your

saw

before

you

begin

a

major

sawing

operation.

a

Accelerate

engine

to

full

throttle

before

entering

cut

by

squeezing

the

throttle

trigger.

b.

Begin

cutting

with

the

saw

frame

against

the

log.

Figure

16

.

c.

Keep

the

engine

at

full

throttle

the

entire

time

you

are

cutting.

d.

Allow

the

chain

to

cut

for

you;

exert

only

light

downward

pressure.

If

you

force

the

cut,

damage

to

the

bar,

chain,

or

engine

can

result.

e.

Release

the

throttle

trigger

as

soon

as

the

cut

is

completed,

allowing

the

engine

to

idle.

If

you

run

the

saw

at

full

throttle

without

a

cutting

load,

unnecessary

wear

can

occur

to

the

chain,

bar,

and

engine.

£

To

avoid

losing

control

when

cut

is

complete,

do

not

put

pressure

on

saw

at

end

of

cut.

g.

Stop

the

engine

before

setting

the

saw

down

af-

ter

cutting.

B.

TREE

FELLING

TECHNIQUES

1.

CAREFULLY

PLAN

YOUR

SAWING

OPERA-

TION

IN

ADVANCE

a.

Clear

the

work

area.

You

need

a

clear

area

all

around

the

tree

whereyou

can

have

secure

footing

at

all

times.

b.

Study

the

natural

conditions

that

can

cause

the

tree

to

fall

in

a

particular

direction.

1.)

The

WIND

direction

and

speed.

2.)

The

LEAN

of

the

tree..

The

lean

of

a

tree

might

not

be

apparent

due

to

uneven

or

slop-

-

12

-

ing

terrain.

Use

a

plumb

or

level

to

determine

the

direction

of

tree

lean.

3.)

WEIGHTED

and

BRANCHES

on

one

side.

4.)

Surrounding

TREES

and

OBSTACLES.

c.

Look

for

decay

and

rot.

If

the

trunk

is

rotted,

it

can

snap

and

fall

toward

the

operator.

d.

Check

for

broken

or

dead

branches

which

can

fall

on

you

while

cutting.

e.

Make

sure

there

is

enough

room

for

the

tree

to

fall.

Maintain

a

distance

of

2

1/2

tree

lengths

from

the

nearest

person

or

other

objects.

Engine

noise

can

drown

out

a

warning

call.
