READ SAFETY RULES AND INSTRUCTIONS CAREFULLY BEFORE OPERATION
Warning: This unit is equipped with an internal combustion engine and should not be used on or near any unimproved forest-covered, brush-
covered or grass-covered land unless the engine’s exhaust system is equipped with a spark arrester meeting applicable local or state laws (if any).
If a spark arrester is used, it should be maintained in effective working order by the operator. In the State of California the above is required by law
(Section 4442 of the California Public Resources Code). Other states may have similar laws. Federal laws apply on federal lands. A spark arrester
for the muffler is available through your nearest engine authorized service dealer or contact the service department, P.O. Box 361131 Cleveland,

DANGER: This machine was built to be operated according to the rules for safe operation in this
manual. As with any type of power equipment, carelessness or error on the part of the operator can
result in serious injury. This machine is capable of amputating hands and feet and throwing objects.
Safe
Operation Failure to observe the following safety instructions could result in serious injury or death.
Training
Preparation
1. Read, understand, and follow all instructions on the ma-
chine and in the manual(s) before attempting to assemble
and operate. Keep this manual in a safe place for future
and regular reference and for ordering replacement parts.
2. Be familiar with all controls and their proper operation.
Know how to stop the machine and disengage them
quickly.
1. Thoroughly inspect the area where the equipment is to
be used. Remove all rocks, bottles, cans, or other foreign
objects which could be picked up or thrown and cause
personal injury or damage to the machine.
2. Always wear safety glasses or safety goggles during opera-
tion or while performing an adjustment or repair, to protect
eyes. Thrown objects which ricochet can cause serious
injury to the eyes.
Practices
3. Never allow children under 16 years old to operate this
machine. Children 16 years old and over should read and
understand the operation instructions and safety rules in
this manual and should be trained and supervised by a
parent.
3. Wear sturdy, rough-soled work shoes and close-fitting
slacks and shirts. Loose fitting clothes or jewelry can be
caught in movable parts. Never operate this machine
in bare feet or sandals. Wear leather work gloves when
feeding material in the chipper chute.
WARNING
4. Never allow adults to operate this machine without proper
instruction.
4. Before starting, check all bolts and screws for proper tight-
ness to be sure the machine is in safe working condition.
Also, visually inspect machine for any damage at frequent
intervals.

5. Keep bystanders, helpers, pets, and children at least
75 feet from the machine while it is in operation. Stop
machine if anyone enters the area.
5. Maintain or replace safety and instructions labels, as
necessary.
6. Never run an engine indoors or in a poorly ventilated area.
Engine exhaust contains carbon monoxide, an odorless
and deadly gas.
6. To avoid personal injury or property damage use extreme
care in handling gasoline. Gasoline is extremely flammable
and the vapors are explosive. Serious personal injury can
occur when gasoline is spilled on yourself or your clothes
which can ignite. Wash your skin and change clothes
immediately.
7. Do not put hands and feet near rotating parts or in the
feeding chambers and discharge opening. Contact with
the rotating impeller can amputate fingers, hands, and
feet.
8. Never attempt to unclog either the feed intake or dis-
charge opening, remove or empty vacuum bag, or inspect
and repair the machine while the engine is running. Shut
the engine off and wait until all moving parts have come
to a complete stop. Disconnect the spark plug wire and

Operation
Maintenance & Storage
1. Do not put hands and feet near rotating parts or in the
feeding chambers and discharge opening. Contact with the
rotating impeller can amputate fingers, hands, and feet.
2. Before starting the machine, make sure the chipper chute,
feed intake, and cutting chamber are empty and free of all
debris.
1. Never tamper with safety devices. Check their proper
operation regularly.
2. Check bolts and screws for proper tightness at frequent
intervals to keep the machine in safe working condition.
Also, visually inspect machine for any damage and repair,
if needed.
ꢀ
3. Thoroughly inspect all material to be shredded and remove
any metal, rocks, bottles, cans, or other foreign objects
which could cause personal injury or damage to the
machine.
3. Before cleaning, repairing, or inspecting, stop the engine
and make certain the impeller and all moving parts have
stopped. Disconnect the spark plug wire and ground it
against the engine to prevent unintended starting.
4. Do not change the engine governor settings or overspeed
the engine. The governor controls the maximum safe
operating speed of the engine.

Yard waste such as leaves and pine needles can be
vacuumed up through the nozzle for shredding. After
material has been shredded by the flail blades on the
impeller assembly, it will be discharged into catcher bag
or through blower chute. Do not attempt to shred or chip
any material other than vegetation found in a normal yard
(i.e. branches, leaves, twigs, etc.) Avoid fibrous plants
such as tomato vines until they are thoroughly dried out.
Materials such as stalks or heavy branches up to 1-1/2” in

2. Clean air cleaner every 25 hours under normal condi-
tions or once a season. Clean every few hours under
extremely dusty conditions. To service the air cleaner,
refer to the separate engine manual packed with your
unit.

3. The spark plug should be cleaned and the gap reset
once a season. Check engine manual for correct plug
type and gap specifications.

Nozzle Height Adjustment
The nozzle can be adjusted to any six positions, ranging
from 5/8” to 4 1/8” ground clearance. The nozzle height
has to be adjusted according to yard conditions.
1. Depress nozzle height adjustment lever towards
wheel. See Figure 14.
2. Move the height adjustment lever forward or backward
to adjust the nozzle upwards or downwards. Make
sure both levers are in the same position.
3. Release lever towards deck.
NOTE: In general, raise the nozzle height to vacuum a
thick layer of leaves or to operate with the blower chute.
Lower the nozzle height for smoother surfaces.

Drive Control Cable Adjustment
Adjust the drive control cable if the yard vacuum does
not self propel with the drive control engaged, or if the
unit hesitates while the engine maintains the same speed
after approximately 20 hours of use.
ꢁ
To move the z-fitting of the drive control cable from its
factory set position in the front hole of the drive control to
the rear hole, proceed as follows:
Maintaining
YourYard
Vacuum
1. a. Push the right side of the control out of the right
hole in the upper handle. See Figure 15A.
b. Pivot control down towards the lower handle.
c. Pivot straight up to remove it from the left hole in
the upper handle. See Figure 15A.
2. There is now sufficient slack in the drive control cable
to grasp the z-fitting with your hand and move it from
the front hole to the rear hole of the drive control. See
Figure 15B.

IMPORTANT: Make sure to insert the z-fitting into the
rear hole as it was inserted in the front hole, that is from
the outside of the drive control.
3. You may now carefully reinstall the drive control by
performing the previous steps in the opposite order
and manner of removal.
IMPORTANT: Once assembled and prior to restarting,
make sure that the cable is properly adjusted. With the
drive control disengaged, the unit should freely pull in
reverse.
