VACUUMING
CHIPPING
OPERATION
Chipping operation also takes place in the processing
chamber° Branches fed down through the chipper chute
enter the processing chamber where a hardened steel
chipper blade, mounted on the spinning flywheel, slices
the material into small chips. The chips are then
propelled out from the processing chamber through the
discharge opening into the collection bag.
Vacuuming operation begins in the processing chamber
where the blades attached to the flywheel spin at up to
3600 RPM, creating a powerful suction Material enters
the processing chamber from beneath the machine
during walk-behind vacuuming and during use of the
blower deflector_ Material enters from the hose during
use of the vacuum hose, The material is then processed
through the chamber (and screen if installed) and exits
from the discharge opening into the collection bag or is
propelled out through the bbwer deflector..

IMPORTANT
Operation
1. Prepare the unit for vacuuming by following the
assembly steps on Page 10.
Spring Operation:
Spring clean-up can be especially difficul!! Leaves
and other debris may have matted down over the
3receding 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.
2. Walk slowly behind the machine to allow the machine
to draw the debris off the ground.
3. In certain conditions it may be necessary to make two
passes over the area
4. Be sure to frequently empty the collection bag. See
Step 1 on Page 12.
5, To stop the machine, move the Engine Control Lever
all the way to the left (toward turtle position) until it stops.
Fall Operation:
6. Listen for all moving parts to come to a complete
stop. There is an audible, distinct sound produced as
the cutting blades slow down. Wait for this sound to stop
before inspecting, servicing, or changing the operating
mode of the machine
Walk-Behind
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, tn the long run, this
is the easiest and fastest way to deal with all of your
Fall leaves-
Vacuuming
Tips and Hints
Q Avoid overfilling the vacuum inlet which can lead to
clogging, especially if the material is wet and soggy.
A steady, smaller flow of materials provides the most
effective results.
C) If possible, vacuum frequently to avoid deep piles of
leaves from accumulating on the lawn.
O Work from the outer edge of leaf piles and gradually
work inward.
13 Use the blower deflector to b!qw the leaves into long
ro;._s-before walk-behind vacuuming if the leaf cover
is sparse.
13 Mow the lawn before the leaves fail to make
vacuuming easier. Keeping your lawn a bit
shorter in the Fail will help a great deal
13 Check and empty the collection bag frequently.
Q Use care when vacuuming near plantings,
ornamentals, mulches, stone or gravel..
Q Avoid vacuuming long twigs and sticks which are
likely to jam or clog the vacuum inlet. Instead,
process twigs and sticks using the chipper chute as
described on Page 25..
IMPORTANT:
IF THE MACHINE ,JAMS OR CLOGS, IMMEDIATELY SHUT OFF

DANGER
To Prevent Personal injuryor Property Damage:
* Never perform maintenance while engine is
runningor when spark plug wire is connectedto spark
plug, exceptwhere specifically instructedto 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 ignitionsourcesare present
such as hot water and space heaters, furnaces,
clothes dryers, stoves, electric motors, etc_
f. Clean the engine by removing any dirt, chaff or
other debris from its exterior.
3. Thoroughly clean the machine, collection bag, hose,
and blower deflector.
4. Check that all hardware is in place and securely
fastened. Refer to the Parts List in this Manual for
replacement hardwarer
NOTE: A yearly check-up by your local Sears Service
Center is a good way to ensure that your machine will
provide maximum performance for the next season.
5. Inspect all visible moving parts for damage,
breakage, and wear_ Repair or replace as needed (refer
to Parts List).
1. Review the "Customer Responsibilities and Storage"
safety rules in the Safety Section of this Manual
6. Touch up paint on all chipped or scratched surfaces
to prevent rust from forming.
2. To prevent engine damage (if the machine is not
used for more than 30 days) follow the steps below:
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,
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 net 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
