HOW TO USE YOUR SHREDDER
Do not attempt to shred or chip any material other
than vegetation found in a normal yard (i.e., branches,
leaves, twigs, etc.).
A WARNING: The shredder discharges
material with considerable velocity. Keep
away from the area around the chute
deflector. Always stop the engine and dis¬
connect the spark plug wire when remov¬
ing or attaching the bag, when changing
containers or when removing the shred¬
ded material, wear safety glasses and
gloves whenever using your shredder.
1. Leaves and small branches up to 1/2" diameter
can be fed into the hopper when it is in the raised
position. See figure 9. If it becomes necessary to
push material into the shredder, use a small diam¬
eter stick—NOT YOUR HANDS. The stick cannot
exceed 1/2" in diameter so it will be ground up if it
gets into the impeller assembly.
A WARNING: Do not put material larger than
1/2" in diameter into the hopper. Material
up to a maximum of 3" in diameter materi¬
al may be fed into the chipper chute. Do
not attempt to shred or chip any material
larger than 3" in diameter. Personal injury
or damage to the machine could result.
2. Leaves and small twigs can be raked into the
shredder when the leaf ramp is lowered to the
ground. See figure 10. Small branches up to 1/2"
diameter can also be fed into the shredder in this
position. See figure 11.

FIGURE 10.
FIGURE 11.
To lower the leaf ramp, use one hand to grasp
the handle at the top of the leaf ramp and lift
slightly. Pull up on the release bar, and lower the
leaf ramp to the ground. Release the bar. See fig¬
ure 12.
3. Bulky material, such as stalks or heavy branches,
up to 3" in diameter should be fed into the chip¬
per chute. See figure 13.
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.
MAINTENANCE
A WARNING: Always stop engine and dis¬
connect spark plug wire before cleaning,
lubricating or performing any repairs or
maintenance.
LUBRICATION
Lubricate the pivot points on the release bar, leaf
ramp, chute deflector and chipper chute once a sea¬
son using a light oil.

tenance instructions.
Maintain engine oil as instructed in the separate
engine manual packed with your unit. Read and follow
instructions carefully.
Service air cleaner every 25 hours under normal con¬
ditions. Clean every few hours under extremely dusty
conditions. Poor engine performance and flooding
usually indicates that the air cleaner should be ser¬
viced. To service the air cleaner, refer to the separate
engine manual packed with your unit.
The spark plug should be cleaned and the gap reset
once a season. Spark plug replacement is recom-
7

I
mended at the start of each season; check engine
manual for correct plug type and gap specifier tions.
Clean the engine regularly with a cloth o' brush.
Keep the cooling system (blower housing area) clean
to permit proper air circulation which is esssntial to
engine performance and life. Be certain to re nove all
dirt and combustible debris from muffler area.
CLEANING
The shredder may be cleaned by running ws ter from
a hose through the hopper assembly and chipper
chute with the engine running. Allow the shr ;dder to
dry thoroughly.
Wash the bag periodically with water. Allow to dry
thoroughly in the shade. Do not use heat.
REMOVING THE FLAIL SCREEN
If the discharge area becomes clogged, rerrove the
flail screen and clean area as follows.
1. Stop the engine, make certain the shrecder has
come to a complete stop and disconnect spark
plug wire from the spark plug before unclogging
the chute.
2. Loosen the two hand knobs on each sid 3 of the
chute deflector. Lift the chute deflector up and tie
it out of the way.
3. Remove two hairpin clips from the clevis pins
which extend through the housing. Remove the
clevis pins. Lift the flail screen from in:;ide the
housing. See figure 14.
4. Clean the screen by scraping or washing with
water. Reinstall the screen.
NOTE: Be certain to reassemble the flail sen ren with
the curved side down as shown in figure 14.
SHARPENING OR REPLACING CHIPPER BLADES
1. Disconnect spark plug wire and move it away
from spark plug.
2. Remove the flail screen as instructed in previous
section.
3. Remove the chipper chute by removing three hex
nuts and washers. A 1/2" wrench is required. See
figure 14.
NOTE: When reassembling, the cupped washer goes
on the bottom of the chipper chute with the cupped
side against the chute.
4. Rotate the impeller assembly by hand until you
locate one of the chipper blades in the chipper
chute opening. Remove the blade, using a 3/16"
alien wrench on the outside of the blade and 1/2"
wrench on the impeller assembly (inside the
housing). See figure 15.
5. Remove the other blade in the same manner.
Replace or sharpen blades. If sharpening, make cer¬
tain to remove an equal amount from each blade.
Reassemble in reverse order.
Make certain blades are reassembled with the sharp
edge facing the direction shown in figure 15 (sharp
edge is assembled toward the slotted opening in the
impeller assembly).
SHARPENING OR REPLACING SHREDDING BLADE
The shredding blade may be removed for sharpening
or replacement as follows.
1. Disconnect spark plug wire and move it away
from spark plug.
2. Lower the leaf ramp. Block up the housing. See
figure 16.
3. Remove the six hex lock nuts and lock washers
from the housing weld bolts using a 1/2" wrench.

piece of wood (2 x 4) into the chute opening.
7. Remove the two outside screws on the blade,
using a 3/16" alien wrench and a 1/2" wrench.
8. Remove the blade by removing the center bolt,
lock washer and flat washer.
NOTE: Use caution when removing the blade to avoid
contacting the weld bolts on the housing.
When sharpening the blade, follow the 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 rotating at high
speeds and may cause damage to the unit.
The blade can be tested for balance by balancing it
on a round shaft screwdriver or nail. Remove metal
from the heavy side until it is balanced evenly. See
figure 17.
When reassembling the blade, tighten to between 550
and 650 inch pounds, or lacking torque wrench, tight¬
en securely.
FLAILS
The flails, located inside the housing, may be
reversed when they become dull. It is suggested that
this procedure be performed by your nearest author¬
ized dealer.
CARBURETOR ADJUSTMENT
A WARNING: If any adjustments are made
to the engine while the engine is running
(e.g. carburetor), keep clear of all moving
parts. Be careful of heated surfaces and
muffler.
Minor carburetor adjustment may be required to com¬
pensate for differences in fuel, temperature, altitude
or load.
NOTE: A DIRTY AIR CLEANER WILL CAUSE
ENGINE TO RUN ROUGH. BE CERTAIN AIR
CLEANER IS CLEAN AND ATTACHED TO THE
CARBURETOR BEFORE ADJUSTING CARBURE¬
TOR.
Do not make unnecessary adjustments. Factory set¬
tings are satisfactory for most applications and condi¬
tions. If adjustment is needed, refer to the separate
engine manual packed with your shredder.
