O

Never

use

the

saw

with

only

one

hand.

You

cannot

control

the

saw

properly

and

you

may

lose

control

and

injure

yourself

severely.

Keep

the

saw

body

close

to

your

body

to

improve

control

and

reduce

strain.

When

cutting

with

the

bottom

part

of

the

chain

the

reactive

force

will

pull

the

saw

away

from

you

towards

the

wood

you

are

cutting.

The

saw

will

control

the

feeding

speed

and

sawdust

will

be

directed

towards

you.

O

There

is

a

risk

of

kickback

if

the

saw

is

pushed

far

enough

so

that

you

begin

to

cut

with

the

nose

of

the

bar.

The

safest

cutting

method

is

to

cut

with

the

bottom

part

of

the

chain.

Sawing

with

the

upper

part

makes

it

much

more

difficult

to

control

the

saw

and

increases

the

risk

of

kickback.

O

In

case

the

chain

locked,

immediately

release

the

throttle

trigger.

If

the

throttle

trigger

keeps

rotating

at

high

speed

with

the

chain

locked,

the

clutch

will

overheat

causing

trouble.

NOTE

Always

keep

the

spiked

bumper

(if

so

equipped)

face

to

a

tree,

because

the

chain

may

suddenly

be

drawn

into

a

tree.

FELLING

Felling

is

more

than

cutting

down

a

tree.

You

must

also

bring

it

down

as

near

to

an

intended

place

as

possible

without

damaging

the

tree

or

anything

else.

Before

felling

a

tree,

carefully

consider

all

conditions

which

may

effecrithe

intended

direction,

such

as:

Angle

of

the

tree.

Shape

of

the

crown.

Snow

load

on

the

crown.

Wind

conditions.

Obstacles

within

tree

range

(e.g.,

other

trees,

power

lines,

roads,

buildings,

etc.).

WARNING

O

Always

observe

the

general

conditions

of

the

tree.

Look

for

decay

and

rot

in

the

trunk

which

will

make

it

more

likely

to

snap

and

start

to

fall

before

you

expect

it.

O

Look

for

dry

branches,

which

may break

and

hit

you

when

you

are

working.

Always

keep

animals

and

people

at

least

twice

the

tree

length

away

while

felling.

Clear

away

shrubs

and

branches

from

around

the

tree.

Prepare

a

path

of

retreat

away

from

the

felling

direction.

BASIC

RULES

FOR

FELLING

TREES

Normally

the

felling

consists

of

two

main

cutting

operations,

notching

and

making

the

felling

cut.

Start

making

the

upper

notch

cut

on

the

side

of

the

tree

facing

the

feeling

direction.

Look

through

the

kerf

as

you

saw

the

lower

cut

so

you

do

not

saw

too

deep

into

the

trunk.

The

notch

should

be

deep

enough

to

create

a

hinge

of

sufficient

width

and

strength.

The

notch

opening

should

be

wide

enough

to

direct

the

fall

of

the

tree

as

long

as

possible.

Saw

the

felling

cut

from

the

other

side

of

the

tree

between

one

and

two

inches

(3-5

cm)

above

the

edge

of

the

notch.

Felling

Never

Always

The

hinge

guides

the

tree.

If

the

trunk

is

completely

cut

through,

you

lose

control

over

the

felling

direction.

Insert

a

wedge

or

a

felling

lever

in

the

cut

well

before

the

tree

becomes

unstable

and

starts

to

move.

This

will

prevent

the

guide

bar

from

binding

in

the

felling

cut

if

you

have

misjudged

the

falling

direction.

Make

sure

no

people

have

come

into

the

range

of

the

falling

tree

before

you

push

it

over.

sides

of

the

&

WARNING

These

methods

are

extremely

dangerous

because

they

involve

the

use

of

the

nose

of

guide

bar

and

can

result

in

kickback.

Only

properly

trained

professionals

should

attempt

these

techniques.

LIMBING

Limbing

is

removing

the

branches

from

a

feller

tree.

&

WARNING

A

majority

of

kickback

accidents

occurduring

limbing.

Do

not

use

the

nose

of

the

guide

bar.

Be

extremely

cautious

and

avoid

contacting

the

log,

other

limbs

or

objects

with

the

nose

of

the

guide

bar.

Be

extremely

cautious

of

limbs

under

tension.

They

can

spring

back

towards

you

and

cause

loss

of

control

resulting

in

injury.

(Fig.

Stand

on

the

left

side

of

the

trunk.

Maintain

a

secure

footing

and

rest

the

saw

on

the

trunk.

Hold

the

saw

close

to

you

so

that

you

are

in

full

control

of

it.

Keep

well

away

from

the

chain.

Move

only

when

the

trunk

is

between

you

and

the

chain.

Watch

out

for

spring

back

of

limbs

under

tension.

LIMBING

THICK

BRANCHES

When

limbing

thick

branches,

the

guide

bar

may

get

pinched

easily.

Branches

under

tension

often

snap

up,

so

cut

troublesome

branches

in

small

steps.

Apply

the

same

principles

as

for

cross

cutting.

Think

ahead

and

be

aware

of

the

possible

consequences

of

all

your

actions.

CROSS

CUTTING/BUCKING

Before

starting

to

cut

through

the

log,

try

to

imagine

what

is

going

to

happen.

Look

out

for

stresses

in

the

log

and

cut

through

it

in

such

a

manner

that

the

guide

bar

will

not

get

pinched.

CROSS

CUTTING

LOGS,

PRESSURE

ON

TOP

Take

a

firm

stance.

Begin

with

an

upper

cut.

Do

not

cut

too

deeply,

about

1/3

of

the

log

diameter

is

enough.

Finish

with

a

bottom

cut.

The

saw

cuts

should

meet.
