Section 3: Features and Controls 9

A DANGER

Contact with rotating cutting blados will

cause serious personal injury. Do not

put hands, face, feet or clothing into the

shredder hopper inlet, chipper chute

inlet, discharge opening, or near the

discharge area at any time.

Perform maintenance and service only

after the engine is off, the spark plug

wire is disconnected and moved away

from the spark plug, and all moving

parts have come to a complete stop.

Then use only a long wooden stick or a

long handled shovel to clear away dis

charged materials or blockages.

CHIPPER CHUTE (INLET)

Material up to 3" in diameter (such as

small branches and vines) can be pro

cessed through the side-mounted chipper

chute (Figure 3-1). Material fed into the

chipper chute is turned into chips by a

chipper blade mounted on a revolving fly

wheel (Figure 3-1A).

directed between the blade and anvil,

where it is sheared off by the blade. The

chips are processed inside the chamber

and then discharged through the dis

charge screen or the optional bar grate.

A WARNING

Do not oporate unit unless chipper chute

is properly bolted to side of unit. Seri

ous personal injury can result if chipper

chute is not securely attached.

CHIPPER/SHREDDER CHAMBER

Inside the chipper/shredder chamber is a

flywheei/cylinder assembly that is belt-

driven by the engine drive shaft.

The flywheel has a chipper blade (A, Figure

3-2) attached to one side. The cylinder

assembly holds 12 shredder cutting blades

(B). During operation, the chipper blade

and shredder blades revolve at the same

time, allowing you to either chip or shred.

Material fed into the shredder hopper is

shredded and ground when the shredder

cutting blades force material against the

chamber baffles and the discharge dis

charge screen. When shredded finely

enough, the material is forced out through

the holes in the discharge screen (or

between the bars of the optional bar grate).

The chipper cutting blade is separated

from a stationary anvil by a gap of 1/16' to

1/8". Material fed into the chipper chute is

Figure 3-2: View Inside cMpper/shredder

chamber shows chipper blade “A ” and a

shredder cutting blade “B".

DISCHARGE OPENING

AND DISCHARGE SCREEN

At the bottom of the unit, under the chip

per/shredder chamber, is a discharge

screen (Figure 3-3) 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", 1" 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). To

remove and install a discharge screen,

refer to Removal/lnstallation Discharge

Screen or Bar Grate in Section 4.

IMPORTANT: Rotating shredder cutting

blades pass within 1/4" of the discharge

screen or bar grate. Keep hands and feet

away at all timesi Never operate

machine unless a discharge screen or

bar grate is secureiy installed.

Figure 3-3: Standard discharge screen has

3/4" diameter holes.

BAR GRATE AHACHMENT (OPTION)

The bar grate attachment (Figure 3-4) has

slotted openings that are wide enough to

efficiently process wet or soggy materials

such as matted leaves, spoiled or leftover

vegetables, manure, etc. If desired, this

coarsely shredded material can then be

dried and later run through the shredder

when a discharge screen is installed. To

remove and install a bar grate, refer to

Removal/lnstallation Discharge Screen or

Bar Grate in Section 4.

Figure 3-4: Optional bar grate.

CLUTCH LEVER

Use the clutch lever (Figure 3-5) when

starting the engine. Engaging the lever

releases tension on the cylinder assembly

drive belt (Figure 3-6) to make engine

starting easier.

When starting the engine, squeeze the

clutch lever against the handlebar while

pulling the recoil rope starter. Release the

clutch lever slowly when the engine starts

and is running smoothly. This action puts

tension on the drive belt to rotate the

shredder cylinder assembly.
