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).
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 beltdriven 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.

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.
