OPERATING INSTRUCTIONS:

If

operated

a

chain

saw,

cut

a

few

lengths

from

a

small

log

to

get

the

feel

of

in ac-

tion.

When

starting

a

cut,

don't

race

the

and

jam

the

saw

into

the

wood.

Slowly

increase

the

throttle

to

engage

the

chain

as

you

start

a

cut

.

Always

maintain

while in a

cut.

Your

and,

be-

cause

of

its high

accion,

you

should

not

on

your

part.

When

Remember.

a

like

any

if

used

without

precautions,

can cause serious

injury.

A

periodic

check

and

help

to

Preventive

is

the

before

they

occur.

To

the

full value

of

your

investment

and

prevent

unnecessary repair bills

together

with loss

of

MUST.

Check

your

chain

daily

and

set

up

a

system

of

regular

inspections

and

rune-ups.

1.

AIR

CLEANER:

Your

air cleaner

is

the

specially proces-

sed filter

element

which fits securely

under

the

top

cover.

To

service,

turn

the

centrally

located

screw

to

the

left

which releases

the

cover. Periodic cleaning

andlor

re:place-

ment

of

this filter

is

required

to

ensure

a

smooth

running

saw. While

the

top

cover

is

off,

wipe all

accumulated

dust

away

from

the

carburetor.

This will

prevent

many

car-

buretor

problems

at

a

later

date.

2.

CYLINDER

HEAD AND FINS,

The

cylinder fins

must

be

kept

thoroughly

clean. Blocked cylinder fins will cause

the

unit

to

overheat. With a

thin tool

remove

any

accum-

ulated

sawdust

from

between

the

fins. This increases

the

cooling effl'ct

of

forced

air

from

the fan

on

the flywheel.

3.

EXHAUST

PORTS: Remove

the

screws securing

t!"le

muf-

fler.

Turn

the

engine

over

to

a position

where

the

piston

is

clear

of

exhaust

ports.

With a

blunt

edged

tool,

care-

fully

remove

any

accumulated

carbon

and

wipe away

small particles

before

reinstalling the muffler. Replace

the

exhaust

gasket if required.

4.

lGNlTlON:

Check

your

spark plug wire for possible wear

or break. During reassembly be careful

that

no

part

of

this wire

is

permitted

to

against

5.

SPARK

PLUG: As in

the

case

of

a1l2-cycle

motors

your

spark plug

should

be

checked

and

kept

clean

of

carbon

and

readjust

to

a gap

of

.030

inches.

6. MAGNETO: Do

not

inspect, remove

or

adjust

the

mag-

neto

unless

absolutely

necessary.

To

check the

breaker

point

gap which

should

be

maintained

at

.015 inches, re-

move

the

cover

and

slowly

turn

the engine over until

the

points

are

open

by

the

cam,

then

with

a feeler gauge,

check

to

It

is

recommended

that

all

magneto

ser-

vice work be carried

out

by

an

authorized

Pioneer dealer.

7. CARBURETOR: As

mentioned,

do

not

change the car-

buretor

needle settings unnecessarily.

Should

the

carbur-

etor,

for

any

reason, need servicing, this

should

be per-

formed

by

your

servicing dealer.

8. CLUTCH:

Th

e

clutch

assembly

of

your

chain saw

is

of

a

centrifugal

type

and

fully

automatic.

The

clutch engages

when

the

throttle

is

opened

to

a

point

where

the engine

revolutions cause

the

clutch

shoes

to

engage. Do

not

slip

your

clutch

through

overloading

as

it

will wear

out

the

shoes.

Paractic~immediately

releasing

the

throttle

if

the

chain

is

pinched

as well as

at

the

end

of

a

cut.

9.

BAR

MAlNTENANCE:

To

assure

that

the

oil reaches

the

chain

at

all times, cleaning

of

the

bar

groove and

the

oil

inlet

hole

is

important.

Remove

sawdust

from

these

areas

after

each

day

of

cutting,

or whenever

the

oil

supply

ap-

pears

inadequate.

To

keep

the

wear equal

on

the

rails

of

the

cutter

bar,

it

should

be

turned

protection

devices.

Always use

caution

when

handling

fuel. Move

the

chain

saw

at

least

10

feet

(3

m)

from

the

fueling

point

before

starting

the

engine.

Do

not

allow

other

persons

to

be

near

the

chain saw

when starring

or

cutting

with

the

chain saw. Keep by-

standers

and

animals

out

of

the

work

area.

Never

start

cutting

until

you

have a clear

work

area, se-

cure

footing,

and

a planned

retreat

path

from

the

falling

trec.

Always hold

the

chain saw firmly

with

both

hands

when

the

engine

is

running. Use a firm grip

with

thumbs

and

fingers encircling

the

chain saw handles. See Figure 8.

FIG

. 8

7. Keep all parts

of

your

body

away

from

the

saw chain

with

the

engine

is

running

.

8. Before

you

start

the

engine,

make

sure

the

saw chain

is

not

contacting

anything.

9. Always

carry

the

chain saw

with

the

engine

stopped.

the

guide bar and saw chain

to

the rear, and the

muffler

away

from

your

body.

10

. Never

operate

a chain saw

that

is

damaged,

improperly

adjusted,

or

is

not

completely

and securely as.sembled.

Be

sure

that

the

saw chain

stops

moving

when

the

throt-

tle

control

trigger

is

released.

11. Always

shut

off

the

engine

before

setting

it

down

.

12

.

Use

extreme

caution

when

cutting

small size

brush

and

saplings because slender material

may

catch the saw chain.

and

be

whipped

toward

you

or

pull

you

off

balance.

13. When

cutting

a limb

that

is

under

tension

be

alert

for

spring

back

so

that

you

will

not

be

struck

when

the

[en-

sian

in

the

wood

fibres

is

released.

14

. Keep

the

handles

dry,

dean

and

free

of

oil or fuel mix·

ture.

15.

Operate

the

chain saw only in well ventilated areas.

16. Do

not

operate

a chain saw

in

a tree.

17. All chain

saw

service,

othe

r

than

the

items listed in the

Owner's

l\-lanual

maintenance

instructions,

should

be

performed

by

competent

chain saw service personnel.

Safety

Warning

(e.g., if

improper

tools

are used

to

remove

the

flywheel,

or

if

an

improper

tool

is

used

to

hold

the

flywheel in

order

to

remove the

clutch,

structural

damage

to

the

flywheel

could

occur

which

could

subsequently

cause

the

flywheel

to

burst).

18. Guard against kickback. Kickback

is

the

upward

motion

of

the

guide

bar

which

occurs

when

the

saw chain

at

the

nose

of

the

guide

bar

contacts

an

object.

l<ickback can

lead to dangerous loss

of

control

of

the

chain saw.

TO

A

VOID

KICKBACK,

Hold

the

chain saw firmly with

both

hands.

Don't

over

reach.

Don't

let

the

nose

of

the

guide bar

contact

a log,

branch,

ground

or

any

other

obstruction.

Cut

at

high

engine speeds.

Don't

cut

above

shoulder

height.

Follow

manufacturer's

sharpening

and

maintenance

instructions

for

the saw chain.

19. When

bucking

a log,

it

is

important

to

make sure

foot-

ing

is

firm

and

weight

is

evenly

distributed

on

both

feet.

If

possible,

the

log

should

be raised

and

supported

by

use

of

limbs, logs or chocks.

When

bucking

on a slope, alw·ays

stand

on

the

uphill

side

of

the

log, as illustrated in Figure 9. When

"cutting

through",

release

the

cQtting pressure near

the

end

of

the

cut. This will

maintain

complete

control

witl;lOut

relaxing

your

grip

on

the

chain saw handles

and

will

avoid allowing

the

saw chain

to

contact

the

ground.

Upon

completion

of

a

cut,

ensure

the

saw chain

is

stop-

ped

before

moving

the

chain saw.

20. As

the

felling

cut

gets close

to

the

hinge the

tree

should

begin

to

fall. If

there

is

any

chance

that

the

tree

might

not

fall in

the

desired direction.

or

may

roc~

back ,and

bind

the

S1\\i

chain,

stop

cutting

before

the

felling

back

cut

is

completed

and

use wedges made

of

wood,

plastic

or

aluminum

to

open

the

cut

and

drop

the tree along

the

desired line

of

fall.

When

the

tree begins

to

fall, remove

the

chain saw

from

the

cut,

stop

the

engine,

put

the

ehain saw

down,

then

use

the

retreat

path

planned. Be alert

for

overhead limbs

falling and watch

your

footing.
