AND

 

BUCKING

 

CUTS

The

 

intention

 

of

 

the

 

following

 

information

 

is

 

to

 

provide

 

you

 

with

 

the

 

general

 

introduction

 

to

 

wood

 

cutting

 

techniques.

 WARNING

 

This

 

information

 

does

 

not

 

cover

 

all

 

speci

fi 

c

 

situations,

 

which

 

may

 

depend

 

on

 

di

 

erences

 

in

 

terrain,

 

vegetation,

 

kind

 

of

 

wood,

 

form

 

and

 

size

 

of

 

trees,

 

etc.

 

Consult

 

your

 

servicing

 

dealer,

 

forestry

 

agent

 

or

 

local

 

forestry

 

schools

 

for

 

advice

 

on

woodcutting

 

problems

 

in

 

your

 

area.

 

This

 

will

 

make

 

your

 

work

 

more

 

e

  

cient

 

and

 

safer.

 

Avoid

 

cutting

 

in

 

adverse

 

weather

 

conditions,

 

such

 

as

 

dense

 

fog,

 

heavy

 

rain,

 

bitter

 

cold,

 

high

 

winds,

 

etc.

 

Adverse

 

weather

 

is

 

often

 

tiring

 

to

 

work

 

in

 

and

 

creates

 

potentially

 

dangerous

 

conditions

 

such

 

as

 

slippery

 

ground.

 

 

High

 

winds

 

may

 

force

 

the

 

tree

 

to

 

fall

 

in

 

an

 

unexpected

 

direction

 

causing

 

property

 

damage

 

or

 

personal

 

injury.

CAUTION

 

Never

 

use

 

a

 

chain

 

saw

 

to

 

pry

 

or

 

for

 

any

 

purpose

 

for

 

which

 

it

 

is

 

not

 

intended.

 WARNING

 

Avoid

 

stumbling

 

on

 

obstacles

 

such

 

as

 

stumps,

 

roots,

 

rocks,

 

branches

 

and

 

fallen

 

trees.

 

Watch

 

out

 

for

 

holes

 

and

 

ditches.

 

Be

 

extremely

 

cautious

 

when

 

working

 

on

 

slopes

 

or

 

uneven

 

ground.

 

Shut

 

o

  

the

 

saw

 

when

 

moving

 

from

 

one

 

work

 

place

 

to

 

another.

 

Always

 

cut

 

at

 

wide

 

open

 

throttle.

 

A

 

slow

 

moving

 

chain

 

can

 

easily

 

catch

 

and

 

force

 

the

 

saw

 

to

 

jerk.

 

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.

 

(

Fig. 19

)

 

When

 

cutting

 

with

 

the

 

upper

 

part

 

of

 

the

 

chain

 

the

 

reactive

 

force

 

will

 

push

 

the

 

saw

 

towards

 

you

 

and

 

away

 

from

 

the

 

wood

 

you

 

are

 

cutting.

 

(

Fig. 20

)

 

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

 

di

  

cult

 

to

 

control

 

the

 

saw

 

and

 

increases

 

the

 

risk

 

of

 

kickback.

 

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

 

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

 

e

 

ect

 

the

 

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

 

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.

 

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

 

su

  

cient

 

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.

 

(

Fig. 21

)

Felling

 

direction

22.

 

45°

 

minimum

 

notch

 

opening

23.

 

Hinge

24.

 

Felling

 

cut

Never

 

saw

 

completely

 

through

 

the

 

trunk.

 

Always

 

leave

 

a

 

hinge.

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.

FELLING CUT, TRUNK DIAMETER MORE THAN TWICE GUIDE 

BAR LENGTH

Cut

 

a

 

large,

 

wide

 

notch.

 

Then

 

cut

 

a

 

recess

 

into

 

the

 

center

 

of

 

the

 

notch.

 

Always

 

leave

 

a

 

hinge

 

on

 

both

 

sides

 

of

 

the

 

center

 

cut.

 

(

Fig. 22

)

Complete

 

the

 

felling

 

cut

 

by

 

sawing

 

around

 

the

 

trunk

 

as

 

in

 

the

 

Fig. 23

.

 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.
