This SHREDDER-BAGGER has been designed, engineered and manufactured to give you the best possible depend-
ability and performance.
0 Should you
experience any minor problem which you cannot easily remedy, please return your SHREDDER-BAGGER
to your nearest Sears, Roebuck and Co. or Simpsons-Sears Limited store. They have well-qualified, competent train·
~ ed technicians and the proper tools to service or repair this unit. NEVER ATTEMPT TO REPAIR YOUR SHRED-
DER-BAGGER UNLESS YOU
ARE QUALIFIED TO DO SO.
Your new SHREDDER-BAGGER
utilizes multiple sharp flat cutting blades rotating about the vertical shaft of its en-
gine within
the cutting chamber. In order to reduce lawn and garden ,bulk by shredding, these blades rotate at a
speed of approximately 18,000 feet per minute or almost 200 miles per hour. They exert about the same force as a
10 pound
sledge hammer traveling at 200 miles per hour and shred materials by simply cutting and forcing them at
this speed against the internal breaker plates. Obviously, this extreme force constitutes a potential danger if the
SHREDDER-BAGGER is not properly used and maintained. It is therefore all the more important that the operator
always FOLLOW THE "RULES FOR SAFE OPERATION" as well as other instructions contain~d in the Owners
Manual.
The SHREDDER-BAGGER
has been shipped from the factory partially assembled, for shipping purposes, All parts
such as nuts, washers, screws, etc. necessary to complete assembly of the SHREDDER-BAGGER have been includ-
ed

preface to operating
There are many gardening applications for your
powerful
new SHREDDER-BAGGER. Probably
your initial use of this unit wi II be to reduce lawn
and garden bulk by shredding it and bagging it for
disposal pick-up. Air pollution ordinances in many
areas have made it illegal to burn this bulk, however
your SHREDDER-BAGGER will allow you to dis-
pose of it properly.

Another prime use for your SHREDDER-BAGGER
wi 11 be in the preparation of a compost pi le. Shred-
ding accelerates the decomposition process. Com-
post is of special value for potting house plants,
use in greenhous.e s, gardens and the like. Some
other uses are for flower beds, rose beds, and as
a top dressing for lawns. The ingredients which go
into the preparation of a compost pile vary de-
pending upon the materials available, but they
usually consist of sod; grass clippings, weeds,
leaves, corn· stalk, discarded vegetable greens
such as carrot tops, etc .Many local libraries have
fine books on gardening and flower bed preparation
and maintenance dealing with the preparation of
compost piles which will apply to your particular
climate, soil conditions and use for the compost
pile.
In order to make your SHREDDER-BAGGER a more
versatile piece of equipment, Sears offers thefol-
lowing accessories:
1. Lawn Cleanup Cart
2. Extra-heavy Plastic Bags
3. Heavy Duty Reusable Bags.
operating
BE AWARE OF ALL THE "RULES FOR SAFE
OPERATION" LISTED ON PAGE 1.
PUT ON YOUR SAFETY GLASSES
1. Position the Shredder-Bagger on level ground.
2. Fill engine crankcase and fuel tank as describ-
ed on page 8.
3. Attach spark plug cover and wire to spark plug.
Refer to Fig. l , Page 2.
4. Move control knob to "start" position.
5. Grasp recoil starter handle and pull sharply.
Do NOT a Ilow starter rope to snap back. Re-
wind
slowly keeping hold of the starter handle
at all times. Several pulls of the starter maybe
necessary to start the engine for the first time or
after it has set idle for a period of time, in
order to pump fuel from the tank to the car-
buretor.
6. After the engine starts, move the control knob to
"fast" position. However, with a brand new en·
gine, we suggest that the control knob he position·
ed midway between the "slow" and "fast" set·
ting·-72 to % throttle for the first 15 minutes of
running at no load, for engine breakin.
7. To stop engine, move the control knob to the
"stop" position.
8. DISCONNECT SPARK PLUG WIRE.
KEEP ALL GUARDS AND DEFLECTORS IN PROP-
ER POSITION AT ALL TIMES.
Your
Shredder-Bagger was designed for best opera·
tion at full "fast" throttle. Be sure discharge chute
deflector is angled downward so that all shredded
material is diverted to discharge toward the ground.
Stalks, long heavy weeds, small branches, etc. can
be hand fed into the hopper. This way the rate of feed
can be controlled to prevent stalling the engine.
However, when this materia I becomes so short as to
be
level with the top, let go, material wil I feed in it·
self. DO NOT lower hands inside the hopper.
6442R-29. 4. 74 • 9 -
If it becomes necessary to push material down in
hopper, use only a 3-foot long piece of soft wood. A
plastering lath, or Y:i" diameter stick are good ex-
amples of what to use. Occasionally there may be a
bounce back of materia I from blades, therefore keep
face away from hopper opening.
lower ramp
1. Grasp cover and ramp and ra 1 se to
unhook from ramp.
2. Lower ramp to ground position.
3. Rotate lever on deflector weldment and hook lev-
er over tubing on bolt at L. H. side of hopper.
4. Leaves or material can now be raked up ramp into
hopper for shredding. Caution: Rake leaves or
material up ramp so that air will mix with material.
Do not overload Shredder.
NOTE: Stop engine and remove spark plug wire each
timea bag is changed. If you do not wish to bag shred-
ded material, remove bagging attachment.
When feeding material into ramp, always feed so that
(throat) bottom is not completely covered. This is
necessary so that air will mix with material for pro-
per discharge. More materia I can be shredded when
ramp is not completely filled. If fed too fast engine
may stall. It will take experience to determine the
proper rate of each material fed into the Shredder for
best performance.
It is not necessary to shred all material to Cl uniform
size. Remember, the main purpose of the Shredder is
to reduce the bulk.
IMPORTANT: When shredding materials with high
moisture content, which may have a tendency to plug,
mix in some dry material such as brush trimmings,
etc. The percentage of dry material added will vary
withmoisture content and condition of material to be
shredded. Generally more dry material .will be needed
with higher moisture material. A continuous mixture
will also help. Experience will teach you the proper
mixtures and rate of feed needed to prevent plugging.
When shredded material builds up at discharge area,
or when bag is nearly filled, stop engine, and remove
spark plug wire from spark plug. Rake material away
from discharge area, or remove filled bag and replace
with new bag. Replace spark plug wire and restart en-
gine.

Do not make unnecessary adjustments. Factory set·
tings are satisfactory for most applications and con·
ditions. If adjustments are needed, proceed as fol.
lows:
A. High speed adjust needle is pre·set at the foe·
tory (l'lt.$ turns open) and readjustment should not
be necessary. (See Figure 27)
B. Close "idle adjust needle" by turning clockwise.
Close finger tight only. Forcing may cause dam· -
age. (See Figure 27)
C. Open "idle adjust needle" l (one) turn by turn·
ing counterclockwise.
D. Start engine. Refer to page 8.
E. With

storage
In the event your Shredder is to be i:ioperative for
periods in excess of 30 day;;··prepare for storage as
outlined below:
1. Drain fuel tank and carburetor by allowing the
engine to run out of gasoline. Gasoline left in
your engine will leave gum deposits and conden·
sation in the carburetor, and fuel tank. This makes
fuel system inoperative, and will result in hard or
non-starting of the engine.
2. Disconnect spark plug, and allow engine to cool
down.
3·. Lubri cote cy Iinder by removing the spark plug.
Pour one (l) ounce of clean lubricating oil
through
the spark plug hole into the cylinder.
Crank the engine slowly to spread oil, and re-
place the spark plug . .
4. Completely
clean inside, and outs'ide of Shredder,
and
engine after each time it is used .It is easier
to clean then, arid will work more efficiently next
time it is used.
5. Apply a light coat of grease, or rust preventative
to hopper, blades and inside walls of cutting cham·
ber.
6. Store in a clean, dry building.
7. Do not save or store gasoline over winter. Stale
gas that has set around, and lost its strength is
a trouble maker--hard starting, and loss of power
resu Its.
