Bulky

material,

such

as

stalks

or

heavy

branches,

up

to

3"

in

diameter

should

be

fed

into

the

chip¬

per

chute.

See

figure

A

WARNING:

Make

certain

leaf

ramp

is

raised

as

shown

when

using

the

chipper

chute.

Also

make

certain

the

chipper

chute

door

is

closed

when

not

in

use.

IMPORTANT:

There

is

a

flail

screen

located

inside

the

housing

in

the

discharge

area.

If

the

flail

screen

becomes

clogged,

remove

and

clean

as

instructed

in

the

Maintenance

section

on

page

8.

For

best

performance,

it

is

important

to

keep

the

shredding

blade

and

the

chipper

blades

sharp.

Refer

to

Maintenance

section,

pages

8

and

9.

If

the

compo¬

sition

of

the

material

being

discharged

changes

(becomes

stringy,

etc.)

or

if

the

rate

at

which

the

material

is

discharged

slows

down

considerably,

it

is

likely

that

the

shredding

blade

and/or

chipper

blades

are

dull

and

need

to

be

sharpened

or

replaced.

original

angle

of

grind

as

a

guide.

It

is

extremely

important

that

each

cutting

edge

receives

an

equal

amount

of

grinding

to

prevent

an

unbalanced

blade.

An

unbalanced

blade

will

cause

excessive

vibration

when

at

high

speeds

and

may

cause

damage

to

the

unit.

The

blade

can

be

tested

for

balance

balancing

it

on

a

round

shaft

screwdriver

or

nail.

Remove

metal

from

CARBURETOR

ADJUSTMENT

A

WARNING:

If

any

adjustments

are

made

to

the

engine

while

the

engine

is

running

(e.g.

carburetor),

ail

moving

parts.

Be

careful

of

heated

surfaces

and

Minor

carburetor

adjustment

may

be

required

to

com¬

pensate

for

differences

in

fuel,

temperature,

altitude

or

load.

NOTE:

A

DIRTY

AIR

CLEANER

WILL

CAUSE

for

most

applications

and

condi¬

tions.

If

adjustment

is

needed,

refer

to

the

separate

engine

manual

packed
