KICKBACK

SAFETY

PRECAUTIONS

A

WARNING!

Either

of

the

following

reactions

Could

cause

you

to

lose

control

of

your

saw

while

cutting,

possibly

resulting

in

serious

injury!

1.

Kickback

may

occur

whenever

the

nose

or

tip

of

the

guide

bar

touches

an

object,

or

when

the

wood

closes

in

and

pinches

the

saw

chain

in

the

cut.

Tip

contact

in

some

cases

may

cause

a

lightning-fast

reverse

reaction,

kicking

the

guide

bar

up

and

back

towards

the

operator.

2.

Pinching

the

saw

chain

along

the

top

of

the

guide

bar

may

push

the

guide

bar

rapidly

back

toward

the

operator!

Either

of

these

reactions

may

cause

you

to

lose

control

of

the

saw,

which

could

result

in

serious

personal

injury.

>

Do

not

rely

exclusively

upon

the

safety

devices

built

into

your

saw!

As

a

chain

saw

user,

you

should

take

several

steps

to

keep

your

cutting

jobs

free

from

accident

or

injury:

1.

With

a

basic

understanding

of

kickback,

you

can

reduce

or

eliminate

the

element

of

surprise.

Sudden

surprise

contributes

to

accidents!

2.

Keep

a

firm

grip

on

the

saw

with

both

hands,

the

right

hand

on

the

rear

handle,

and

the

left

hand

on

the

front

handle,

whenever

the

engine

is

running.

Use

a

firm

grip

with

thumbs

and

fingers

encircling

the

chain

saw

handles.

A

firm

grip

will

help

you

to

reduce

kickback

and

maintain

control

of

the

saw.

Make

sure

that

the

area

in

which

you

are

cutting

is

free

from

obstructions.

Do

not

let

the

nose

of

the

guide

bar

contact

a

log,

branch,

or

any

other

obstructions

which

could

be

hit

while

you

are

operating

the

saw.

.

Cut

at

high

engine

speeds.

Do

not

overreach

or

attempt

to

cut

above

shoulder

height!

Follow

the

manufacture’s

instructions

for

sharpening

and

maintenance

of

the

saw

chain.

.

Use

only

the

replacement

bars

and

chains

or

equivalent

as

specified

by

the

manufacturer.

.

Use

low-kickback
