PERSONAL INJURY COULD RESULT.
5. Remove supports from beneath machine.
STEP 1: REMOVE OR INSTALL SHREDDER SCREEN
A shredder screen (A, Figure 3) is factory-installed inside the processing chamber. Vacuumed or chipped material passes through the slots in the screen before it is discharged. The screen produces up to an 8:1 reduction of material.
The screen is designed for use only with dry materials. Before processing damp materials, remove the screen to reduce clogging and to improve air flow inside the processing chamber. Before chipping a large number of branches, remove the shredder screen for faster discharge of the chips.
To Remove Shredder Screen:
1. Stop the engine, disconnect the sparkplug wire
from the sparkplug, and make sure that ail moving
parts have come to a complete stop.
2. To remove rear rod (B, Figure 3), remove the
collection bag or the blower deflector (if installed). Then, remove the hair pin clip (D) and puli the rod out through the bottom of the deck
3. Use sturdy supports to prop up the right side of the
machine a few inches. Then, remove the hair pin clip (D) and puli the front rod (C) out through the bottom of the deck
To install Shredder Screen:
1. Stop the engine, disconnect the spark plug wire
from the spark plug, and make sure that ail moving
parts have come to a complete stop.
2. Remove the collection bag Remove the rods and
hair pin clips which were stored on the shredder screen. Insert the screen (A) into the processing chamber with the flat, angled end facing to the rear and the curve in the screen facing to the right See Figure 3. Align mounting holes in screen with the holes in deck.
3. Using sturdy supports, prop up the right side of the machine a few inches, insert front rod (C) up through bottom of deck, into screen mounting hole, and out through the top of the deck.

DANGER

To Prevent Personal Injury or Property Damage:
• Cutting blades begin to rotate when the engine starts and slow down gradually after the engine is shut off. Do not allow hands or any other part of the body or olothing inside the vacuum inlet, chipper chute, discharge opening, blower deflector opening, or near any moving part.
• Do not run the engine in an enclosed area. Engine exhaust contains carbon monoxide gas, a deadly poison that is odorless, colorless and tasteless. Do not operate this equipment near buildings, windows, or air conditioners.

SAFETY INTERLOCK SYSTEM

Your machine is equipped with a Safety Interlock System which prevents the engine from starting unless the collection bag (or blower deflector) is installed The rod
(A, Figure 20) must be positioned as shown in slot (B) in
order to start the engine. The system also stops the engine if the operator attempts
to remove the bag or blower deflector while the engine is
running. When the rod is not in place, a circuit closes to
ground out the engine
If the safety interlock system fails, shut off the engine and
do not operate the machine until the system has been
repaired. Contact your local Sears service center for repairs.

WARNING

To avoid personal injury or property damage, do not operate this machine unless the safety interlock system is functioning properly.

OPERATION

VACUUMING OPERATION

Vacuuming operation begins in the processing chamber where the blades attached to the fiywheel spin at up to 3600 RPM, creating a powerful suction yaterial enters the processing chamber from beneath the machine during waik-behind vacuuming and during use of the biower deflector. Material enters from the hose during use of the vacuum hose. The material is then processed

CHIPPING OPERATION

Chipping operation also takes place in the processing chamber. Branches ted down through the chipper chute
enter the processing chamber where a hardened steel chipper blade, mounted on the spinning flywheel, slices the materia! into small chips. The chips are then
propelled out from the processing chamber through the
discharge opening into the collection bag.

nmmñ
To Prevent Personal Injury or Properly Damage: » Cutting blades begin to rotate when the engine
starts and slow down gradually alter the engine is shut off. Do not allow hands or any other part of the
body or olothing inside the vacuum hose opening, blower discharge opening, chipper chute, or near any moving pari.
« Before inspecting, cleaning, or servicing the
machine, stop the engine and make sure that all moving parts have come to a complete slop. Disconnect the spark plug wire and secure it away from the spark plug.
• To avoid personal injury or property damage, do not operate this machine for vacuuming unless the collection bag is installed.
« Review all of the rules in the Salety Section of this iWanual,
IMPORTANT
Spring Operation:
Spring clean-up can be especially difficult! Leaves and other debris may have matted down over the preceding months For best results when vacuuming this type of debris: remove the screen, lower the vacuum inlet, and walk slowly. You can even use the machine as you would a vacuum cleaner, moving it back and forth over particularly stubborn debris, or loosen the debris with a few quick passes of a rake, and then vacuum.
Fall Operation:
Don't try to vacuum too much at one time! Optimum
performance is obtained when leaves are vacuumed once a week, or even more often at the peak of leaf­drop. Keep ahead of the leaves in the long run, this
is the easiest and fastest way to deal with ail of your
Fall leaves-
Walk-Behind Vacuuming Tips and Hints
□ Avoid overfilling the vacuum inlet which can lead to
clogging, especially if the materia! is wet and soggy. A steady, smaller flow of materials provides the most effective results,
□ Work from the outer edge of leaf piles and gradually
work inward.
Mow the lawn before the leaves fall to make
vacuuming easier. Keeping your lawn a bit
shorter in the Fall will help a great deal.
□ Check and empty the collection bag frequently.
IMPORTANT: !F THE MACHINE JAMS OR CLOGS, IMMEDIATELY SHUT OFF
THE ENGINE AND DISCONNECT THE SPARK PLUG WIRE FROM THE SPARK
PLUG. REFER TO PAGE 26 FOR SAFETY PRECAUTIONS AND DETAILED INSTRUCTIONS ON HOW TO REMOVE JAMS AND CLOGS.
□ If possible, vacuum frequently to avoid deep piles of
leaves from accumulating on the lawn,
□ Use care when vacuuming near pianiings,
ornamentals, mulches, stone or gravel.
□ Use the blower deflector to blow the leaves into long
rows before walk-behind vacuuming if the ieaf cover is sparse.
□ Avoid vacuuming long twigs and sticks which are
iikeiy to jam or clog the vacuum inlet Instead, process twigs and sticks using the chipper chute as described on Page 25.

STORAGE

OFF-SEASON STORAGE

QANGER

A
To Prevent Personal Injury or Property Damage;
• Never periorm maintenance while engine is running Of when spark plug wire is connected to spark plug, except where specilically instructed to do so.
• Never store machine with fuel in the fuel tank inside a building where fumes may reach an open flame or spark, or where ignition sources are present such as hot water and space heaters, furnaces, clothes dryers, stoves, electric motors, etc.
NOTE; A yearly check-up by your local Sears Service Center is a good way to ensure that your machine will provide maximum pertormance for the next season.
1. Review the “Customer Responsibilities and Storage” safety rules in the Safety Section of this Manual.
2. To prevent engine damage (if the machine is not used for more than 30 days) follow the steps below;
a. it is important to prevent gum deposits from
forming In essential fuel system parts such as the carburetor, fuel filter, fuel hose or tank during storage. Also, experience indicates that alcohol blended fuels (called gasohol or using ethanol or
methanol) can attract moisture which leads to separation and formation of acids during storage
Acidic gas can damage the fuel system of an
engine while in storage.
b. To remove gasoline, run the engine until the tank
is empty and the engine stops.
c. if you do not want to remove gasoline, a fuel
stabilizer (such as Craftsman Fuel Stabilizer No
335500) may be added to any gasoline left in the tank to minimize gum deposits and acids If the tank is almost empty, mix the stabilizer with fresh gasoline in a separate container and add some to the tank. ALWAYS FOLLOW INSTRUCTIONS ON THE STABILIZER CONTAINER. THEN. RUN THE ENGINE AT LEAST 10 MINUTES AFTER THE STABILIZER IS ADDED TO ALLOW
MIXTURE TO REACH CARBURETOR. STORE
THE MACHINE IN A SAFE PLACE. SEE
DANGER ABOVE
d. Change the oil if if has not been changed in the
iast three months. See Page 28,
e. Lubricate the piston/cylinder area. First, remove
the spark plug. Then, squirt approximately 1/2 ounce of clean engine oil Into the spark plug hole. Cover the spark plug hole with a rag to absorb oil
spray and then rotate the engine by pulling the starter rope two or three times. Finally, re-install
the spark plug.
i Clean the engine by removing any dirt, chaff or
other debris from its exterior.
3. Thoroughly clean the machine, collection bag, hose, and blower deffector.
4. Check that all hardware is In place and securely fastened. Refer to the Parts List in this Manual for replacement hardware,
5. Inspect ali visible moving parts for damage, breakage, and wear. Repair or replace as needed (refer to Parts List).
6. Touch up paint on ail chipped or scratched surfaces to prevent rust from forming.
7. If possible, store machine indoors (see DANGER statement on this page). Cover machine for protection
from dust and dirt. Use a covering (not plastic) that does
not retain moisture. Be sure the engine and muffler are
cool before covering the machine.
