under

the

chip¬

per/shredder

chamber,

is

a

discharge

screen

(Figure

through

which

pro¬

cessed

materials

must

pass

before

being

discharged

from

the

unit.

The

diameter

of

the

holes

in

the

screen

determines

how

finely

the

materials

are

shredded.

The

unit

comes

equipped

with

a

screen

that

has

3/4"

holes.

Optional

screens

having

3/8",

r

or

1-3/4'

holes

are

avail¬

able.

The

smaller

holes

produce

more

finely

shredded

particles.

The

larger

holes

produce

more

coarsely

processed

material

and

may

not

clog

as

readily

when

wet,

soggy

or

green

materials

are

processed.

(A

bar

grate

for

processing

very

wet,

heavy

materials

is

also

available).

SOME

MATERIALS

SHOULD

BE

SHREDDED,

OTHERS

SHOULD

BE

CHIPPED.

HERE’S

HOW

TO

DECIDE

WHICH

METHOD

TO

USE:

To

enjoy

the

greatest

benefits

from

the

unit,

it

is

important

to

know

which

materi¬

als

are

best

fed

into

the

shredder

hopper

and

which

ones

are

best

fed

into

the

chip¬

per

chute.

Use

the

following

information

as

a

guide.

IMPORTANT:

Refer

to

Using

the

Shredder

and

Using

the

Chipper

in

this

Section

of

the

Manual

for

detailed

operat¬

ing

instructions.

Do

not

food

the

following

IMPORTANT:

Do

not

allow

processed

material

to

build

up

beneath

or

beside

the

unit

to

the

point

where

it

contacts

the

discharge

screen.

If

material

cannot

freely

exit

the

discharge

screen,

it

will

continue

to

circulate

within

the

processing

chamber.

This

leads

to

clogs

and

the

possibility

of

some

of

the

material

being

“blown”

back

up

through

the

hopper.

If

shredded

material

builds

up

beneath

the

unit,

do

not

attempt

to

remove

it

until

the

engine

is

stopped,

the

Operation

USING

THE

SHREDDER

IMPORTANT:

Always

wear

safety

goggles

(with

side

shields),

appropriate

gloves,

and

hearing

protection.

Read

and

follow

the

safety

rules

in

this

Manual.

A

DANGER

Contact

with

rotating

cutting

blades

will

cause

serious

personal

injury.

The

blades

rotate

when

engine

is

on

and

slow

gradually

after

engine

is

shut

off.

Keep

hands,

feet

and

clothing

out

of

chipper

Inlet,

shredder

feed

inlet

and

discharge

opening

when

unit

is

running.

•

When

the

engine

starts,

the

cutting

blades

inside

the

chipper/shredder

cham¬

ber

will

begin

to

revolve

at

a

high

rate

of

speed.

The

shredder

is

then

ready

to

use.

•

Do

not

feed

material

into

the

shredder

hopper

from

the

engine

side

of

the

unit.

Always

avoid

the

hot

muffler

on

the

engine.

•

When

feeding

material

into

the

shred¬

der,

stand

a

foot

or

two

away

from

the

hopper

opening

and

keep

your

arms

and

hands

parallel

to

and

several

inches

above

the

top

edge

of

the

hopper.

See

Figure

4-

4.

Do

not

point

hands

or

arms

downward

toward

the

hopper

opening

or

put

hands

or

arms

inside

the

hopper.

•

Feed

materials

into

the

shredder

slowly,

and

in

limited

quantities,

until

you

become

familiar

with

its

operation.

Bulk

and

lengths

can

be

increased

gradually

if

the

material

is

being

processed

easily.

Do

not

overload

the

shredder

as

doing

so

will

cause

the

engine

speed

to

decrease

significantly.

•

A

steady

flow

of

materials

into

the

shredder

hopper

provides

the

most

effec¬

tive

results.

The

rate

of

feed

for

small

branches,

vines

(2-3

foot

lengths

only),

and

brush

can

be

controlled

by

lightly

pushing

and

guiding

the

free

end

of

the

material

until

it

extends

above

the

top

of

the

hopper.

At

this

point,

LET

GO

OF

THE

MATERIAL.

The

cutting

blades

can

tug

suddenly

at

material

being

fed

into

the

hopper.

Do

not

hold

onto

the

material

I

Always

hold

material

loosely

and

be

ready

to

let

go

of

it

quickly.

A

DANGER

The

rotating

shredder

blades

can

tug

suddenly

at

material

being

fed

into

the

shredder

hopper.

Contact

with

cutting

blades

will

cause

severe

personal

injury.

Do

not

hold

on

too

tightly

to

branches

and

vines.

Do

not

feed

material

straight

down

into

the

hopper

with

your

arm

pointing

downward

toward

the

opening.

Instead,

keep

your

arms

parallel

to

the

ground

and

several

inches

above

the

top

edge

of

the

hopper.

NOTE:

It

is

best

to

cut

long

branches

into

3-5

foot

lengths

and

vines

to

2-3

foot

lengths

before

feeding

them

into

the

shredder

hopper.

When

shredding

wet

material,

mix

dry

material

in

with

it.

Alter¬

nating

wet

and

dry

material

helps

prevent

material

from

sticking

inside

the

shredder

chamber.

Very

wet

materials

should

be

processed

using

the

optional

Bar

Grate

at¬

tachment.

Refer

to

Shredding

Wet,

Soggy,

or

Green

Materials

in

this

Section

for

other

methods

of

processing

wet

or

green

materials.

Also:

•

Do

not

put

any

part

of

your

body

or

clothing

inside

the

shredder

hopper

or

near

the

discharge

area.

•

Stand

clear

of

the

discharge

area.

•

Keep

face

and

body

away

from

the

dis¬

charge

area.

•

Use

the

leaf

tamper

(Figure

4-4)

**

supplied

with

the

unit

to

push

bulky

material

into

the

shredder

hopper.

DO

NOT

USE

YOUR

HANDS!

•

When

feeding

loose

material,

such

as

leaves,

straw

or

grass

clippings,

just

drop

the

material

into

the

shredder

opening

and

push

it

into

the

shredder

hopper

using

the

leaf

tamper

(supplied).

Do

not

allow

com¬

bustible

materials

to

contact

the

hot

engine.

•

If

the

engine

slows

down

under

load,

stop

feeding

material

and

allow

the

engine

to

regain

full

speed

before

continuing.

Overloading

the

shredder

could

result

in

damage

to

the

belt

or

engine.

•

All

shredded

material

will

be

forced
