SPARK/FIREHAZARD

GAS ENGINES MAY REQUIRE

A SPARK ARRESTER FOR SAFE OPERATION

If the engine on this unit is not equipped with a

spark arrester and is to be used on any forest,

brush, or grass-covered unimproved land, a spark

arrester must be added to the muffler before using

the engine on such land. The arrester must be

maintained in effective working order by the

operator. In the State of California, the above is

required by law (Section 4442 of the California

Public Resources Code.) Other states may have

similar laws. Federal laws apply on federal lands.

See your authorized engine service center for

muffler spark arrester options.

MODEL SPECIFICATIONS

OPERATION

DESCRIPTION

General

Yournewchipper/shredderisdesigned to permityears

oftrouble-freeoperationwhile handling a wide range of

chippingand shredding needs.

To help you get the most out of your investment, as well

as to help you understand how the unit works, this

section explains the basic operation of the chipper/

shredder.

Chipper Operation

The chipper is designed to handle tree limbs and

branchedupto3”indiameter(2-1/2” on models with 5.5

hp&6hp engines).The powerfulmotor and durable

chipping knives also permit the unit to process tough

organic matter such as corn stalks and berry canes.

Tree limbs and branches are inserted“butt end”first into

the chipper cone and are fed into the chipper block,

where two chipper knives mounted on a heavy duty rotor

rotateat 3600 rpm.The sharp cutting edgesand angle of

the blades actually pulls the tree limbs and branches

into the chipper block, cutting wood into small chips,

andpromotingrapid material processing.

The chips of material then pass through a slot in the

rotorbehindthechipper knives, where discharge air flow

conveys them through the fan chamber and out of the

dischargechute.

Shredder Operation

The shredder is designed to shred light brush, leaves,

and other soft but bulky organic waste. As this material

is loaded into the shredder hopper, it is pulled into the

pathofpatented swinging triangular and “J” shaped

shreddinghammers.

The hammers cut and grind the waste into progressively

smaller pieces, and air flow then conveys the reduced

waste out of the discharge chute.

Becauseofthisunique swinging hammer design and

triangularshape, the chipper/shredder has 300% more

shreddingpower than conventionalrectangular

shreddinghammersusedbyothers.

The Vacuum Action

Inadditiontothe shredding hammers and chipping

knives, the rotor has four fan blades integrated into its

design.When the rotor is spinning, a vacuum action is

created,whichpullswaste down into the shredder

hopperand into thegrinding chamber.

These spinning fan blades also create a blowing force

that ejects the shredded or chipped material out of the

discharge chute, making room for more material to be

pulledinandprocessed.

OptionalVacuum Attachment

The vacuum force created by the design of the fan

blades and rotor makes it possible to equip your

chipper/shredderwithanoptional vacuum attachment

that greatly simplifies the processing of leaves and

other loose waste.The vacuum kit attaches directly to

the back of the grinder, and after a cover is placed over

the shredder hopper, the vacuum action is diverted to

the vacuum attachment.

The vacuum kit allows leaved to be raked directly into

the leaf tray, where vacuum action draws the material

intotheshredding chamber.

Forhard-to-reachplaces,anozzleandhandle assembly

can be used to vacuum material up much like a vacuum

cleaner.The strength of the vacuum can be adjusted for

different situations by turning a sleeve on the assembly.

SITE LOCATION

1. Select an area with firm level ground, covered by dirt

or grass. Do not operate on wet, slick surfaces or in

areas with heavy pedestrian traffic.

2. Locate the unit near the waste materials to be

processed to reduce lifting and carrying.

3. Trim and stack the materials for more efficient and

safeoperationofthechipper/shredderunit.

4. Providesufficientroomformaneuveringaroundthe

chipper/shredder.Neverset upthe work areaso that

operatorsmustreachover the chipper/shredder or

have to step over materials to be processed.

5. Reviewall operatingsafety instructions before

proceeding.

DANGER

Internal combustion engines produce Carbon

Monoxide,a colorless, odorless,and tastelessgas

that can cause dizziness, nausea,

unconsciousness,andevenbraindamageor death

is inhaled for prolonged periods.

Operate the chipper/shredder outdoors in a well

ventilated location only.

serious injury or death to you or bystanders.

OPERATION

CHECKS BEFORE STARTING

1. Inspectthechipperconeandshredderhopper for

debris and other objects that may have fallen into the

machine while the unit was stored, and remove them

before starting the unit. Before reaching into the

openings turn off the ignition and disconnect and

secure the spark plug wire.

2. Inspectthechippercone and shredder hopper,and

make sure that they are firmly attached to the

housing.

3. Check all parts to ensure that they are properly

attachedandthat all fasteners are properly tightened.

4. Make sure the discharge chute deflector pivots freely,

allowing mulch to be discharged freely.If the deflector

does not pivot, loosen the mounting screw slightly to

reduce tension on the pivot point.

5. Before attempting to start the engine, make sure:

• Engine oil is full.

• Nofuelhasspilledontoengineor surrounding

components.

• Allhardwareandparts are properly secured.

• Noforeignobjectsare in chipper cone or shredder

hopper.

• Your clothing is not excessively loose or hanging

down,andyouarenotwearingjewelryorother

articles that could get caught in the machinery.

STARTING UP

The controls required to start and run the chipper/

shredderarelocatedontheengine,andaremarked

“Choke”and“Throttle.”

Seethe engine service manual shipped withyour

chipper/shredderfor additional information.

Cold Starts

1. Move choke lever to full choke position.

2. Move throttle lever to “Start.”

3. Place foot on front support leg to hold unit firmly in

place, and adopt a stable stance.

4. Pull starting rope out slowly one time and allow to

return normally.

5.Pull starting rope out rapidly and allow to return

normally.

6. When engine starts, gradually move choke lever to

“nochoke”positionandincreasethrottlespeed.

7. Adjust throttle speed to “high” for best chipper/

shredderaction.

Restarting AWarm Engine

Restarting an engine that is already warm from previous

runningdoesnot normally require use of choke.

1. Move throttle to “Start.”

2. Place foot on front support leg to hold unit firmly in

place, and adopt a stable stance.

3. Pull starting rope out rapidly until engine starts.Allow

ropetoreturnnormally.

4. Adjust throttle speed to “high” for best chipper/

shredderaction.

Idle Speed

Use the “Low” position on the throttle lever to reduce

stress on the engine when chipping or shredding is not

beingperformed. Lowering the enginespeedto “idle” the

engine will help extend the life of the motor, as well as

conserve fuel and reduce the noise level of the

equipment.

Operating Speed

Fornormalchipping, shredding, and vacuuming

operation set the throttle level to “Fast.”

OPERATING INSTRUCTIONS

General

Your chipper/shredder is easy to set up and operate, but

requires simple precautions that are very important, but

easy to follow.

Please review the following instructions and illustrations

carefully.Always comply with these and all other safety

and operating instructions in this manual, and on

warninglabelson the chipper shredder unit, whenever

handlingoroperatingthis machinery.

Alwayswearsafetygoggleswhenoperatingthe chipper/

shredder.Neverallow anyoneto operate the unit or

remainintheimmediate area unless they are wearing

approvedsafetygoggles.

Proper Stance for Chipping

Always maintain a stable, well-balanced stance to one

sideoftheunit when operating the chipper/shredder.

Never stand directly in front of the chipper cone when

performingchippingoperations,since occasional

OPERATION

kick backs may occur, and result in you being struck by

the tree limb or branch being kicked back. Hold tree

limbs and branches carefully to maintain control as they

are being fed into the chipper cone, letting the self-

feeding action of the unit pull the material in.

Neverwrapyourfingersaroundtreelimbsandbranches

so tightly that you can’t let go quickly if the tree limb or

branch is suddenly pulled into the chipper block or

shredderhopperarea.

Leavesandother lightweight organic matter can be

quicklyshreddedinyour chipper/shredder and reduced

to 1/20th of their original volume. Place material to be

shreddedintothe shredder hopper.Avoidlarge amounts

of wet material that can cause shredded matter to build

upinthedischargechuteandpreventproperdischarge.

Alternate the processing of dry and wet materials to help

prevent clogging of the discharge chute.When time

permits, let wet material dry out for a few days prior to

shredding.

Properly Feeding Longer Materials

For Shredding

Whenprocessingbrush,small branches, or other long

types of organic matter, feed the materials to be

shreddedintothe shredder hopper lengthwise, butt end

first, to prevent clogging of the hopper.If brush gets

tangled and clogged as it’s being fed into the hopper,

never reach into the hopper to clear it while the unit is

running. Shut the engine off, let the rotor come to a

complete stop, and disconnect and secure the spark

plugwirebeforeattemptingtoclearthehopper.

NOTE:Be sure to shut off the engine and allow the rotor

to stop completely before emptying the bag.

6. Cut any leftover material in to 1” pieces and process

thethrough the shredderhopper.

SHUTTING DOWN

Whenyou’redoneusing the chipper/shredder,following

these simple but worthwhile steps will help you shut

down the unit properly so that your next use will be

trouble-free.

1. Whenyouhavecompleted processing the materials

to be chipped or shredded, shut the engine off and

allow the rotor to come to a complete stop before

proceeding.

2. Remove the spark plug wire from the spark plug to

prevent the possibility of inadvertent starting.

3. Inspectthefollowingareas for any remaining

materials that may have built up or become caught

duringthefinal chipping and shredding operations:

•SHREDDERHOPPER

Visuallyinspectinside of shredder hopper,and

removeanymaterialremaininginside.

• CHIPPERCONE

Visually inspect chipper cone to ensure that

there are no pieces of tree limbs, branches, or

anyotherdebris remaining inside. Remove and

discard this debris.

• DISCHARGECHUTE

Lift the discharge deflector, and inspect the chute

forclogsor other build up, and remove as required.

This area is most likely to require clean out if wet

orgreenorganic materials have been shredded.

• ENGINE RECOIL STARTER AREA

This area of the engine is also the intake for the

motor’s air cooling fans.Remove any buildup of

grass or shredded material that may have

accumulatedaroundtheintake openings. Use care

topreventbuildup from being pushed into the

intakeareaduring cleaning.

Engine and surrounding parts become extremely

hotduring normal use,and willcause serious burn

injuries if touched before the engine has cooled.

Allow engine to cool completely before touching

thesehot surfaces.

DANGER

MATERIAL PROCESSING

General

Most materials to be processed can be handled more

efficientlybyobservingthefollowingchipper/shredder

operatingtips:

Shredding

1. Donotoverload the shredder hopper by dumping

largevolumesofmaterial into the hopper opening.

2. Alternate wet and dry material to prevent the

dischargechutefrombecoming plugged.

3. Never use any object to force material into the

shredder chamber. It could get caught in the

shreddinghammersand damage the unit, reducing

shredderhammereffectiveness.

Chipping

1. Prune tree limbs and large branches to limit size to

themaximumdiameterallowed.Pruningtreelimbs

and branches close to the main portion of the limb or

branch will make feeding into the chipper cone easier,

and will help you maintain control as the material is

drawninto the chipper block.

2. Large, hard, or dried-out tree limbs that tend to resist

chipping can be processed by rotating them manually

as you alternately insert and retract them in the

chippercone.

3. If the material to be chipped is extremely hard and

kicks back forcefully, or cannot be easily controlled

while it is being fed into the unit, remove the material

immediately and set it aside.You may need to

sharpenthechipperblades to process the material.

Consult the maintenance and service section of this

manual for sharpening instructions, or take your unit

toan authorized service center forprompt, reliable

service.

4.Ifnormalchippingoperationbeginstorequire

additional feeding force to process material, the

chipperknivesmay be in need of routine sharpening.

See the maintenance and service section of this

manual for sharpening instructions, or take your unit

toan authorized service center forprompt, reliable

service.

5. Always try to maintain adequate control of the tree

limbs and branches being fed into the chipper cone to

preventthemfromwhippingaroundandcausinginjury

to you or damage to the cone. Larger limbs and

branches may have a tendency to kick back toward

the operator, so always be alert as you feed materials

into the cone.

toxic if inhaled, so never store the chipper/shredder in

anystructure used for human oranimal habitation.

Here’s a quick checklist of things to do when storing

yourchipper/shredder temporarily,or between uses:

• Store the unit in a location where there’s no danger of

overhead objects falling into the chipper cone or

shredderhopper.

• Keep the unit in an area away from where children

may come into contact with it. If there’s any chance

of unauthorized use, remove the spark plug, and put

in a safe place. Be sure to protect the spark plug

opening from foreign objects with a suitable cover.

• Never put the unit away while the engine is still hot

from running. Let the engine cool down first to

prevent the chance of fire.

• Never try to lift or position the unit in the storage area

by holding the fuel tank. Always let the engine and

muffler cool completely before allowing yourself to

contact these parts.

• If the unit can’t be stored on a reasonably level

surface, use a block of wood to block the wheels.

Neverstorethechipper/shredder where it will not be

in a stable condition.

• Never tip the unit more than 75° from vertical, and

never lay the unit down on its side, as this could

causefuelleakageand undesirable oil transfer into

Clean/Oil/Replace Air Filter Element

dirt, dust, and other work site debris from the air before

it can enter the carburetor and damage sensitive fuel

passages.

Inspect Starter Rope/Handle

Therecoilstarter rope and handle should beinspected

for signs of abrasion or wear that could result in

breakage.

Don’t use worn out parts, since they could break while

tension is applied to the rope, throwing you off balance.

Contactyourlocalauthorized dealer for replacement if

these parts need to be replaced.

Inspect Chipper Cone & Shredder Hopper

Thechipperconeandshredderhopperaremadeofa

highlydurablepolyethylenematerialthatcanwithstand

shredderwastematerial processing.

Check these parts to make sure that they haven’t been

damaged or worn excessively by constant use, and

replace them if they are cracked, worn out, or no longer

fit securely on the chipper/shredder unit.

Cracks, worn areas, and loose attachment points can

cause material to jam or clog when feeding it into the

machine, and may result in kick back or other hazard to

theoperator.

Contact your local dealer for replacement parts if your

unit shows any evidence of these problems, and

discontinue use of the unit until the appropriate repairs

canbe made.

Never try to make temporary repairs yourself, as the

repairscould give way during chipper/shredder

operation, and expose you and bystanders in the area to

risk of injury.

Never attempt to install non-factory parts on your

chipper/shredderunit.Theseparts could appear tofit,

but could cause operating and safety problems that

mightleadtoequipmentdamageand/orinjury.

Inspect Hopper Guards

Thehopperguards are made of a tough, flexible material

thatpermits easy loading ofthe hopper, whilepreventing

shreddedpiecesfrombeing ejected out toward the

the cylinder head. Excessive oil in the cylinder head

will prevent unit from starting properly and cause

enginesmoking.

• Overheadobjectsthat fall into shredder hopper may

cause damage to the unit or serious injury to user and

others if not detected before unit is started.

LONGTERM STORAGE

(Longer than 30 Days)

Seethe engine service manual shipped withyour

chipper/shredderfor additional information.

Yourchipper/shredder can be safelystored duringoff-

seasons by following these simple storage instructions:

• Drain fuel system completely (See the engine service
