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.  
Practices  
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.  
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.  
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.  
WARNING  
4. Never allow adults to operate this machine without proper  
instruction.

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.  
6. Never run an engine indoors or in a poorly ventilated area.  
Engine exhaust contains carbon monoxide, an odorless  
and deadly gas.  
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. Maintain or replace safety and instructions labels, as  
necessary.  
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  
ground it against the engine.  
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.

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  
diameter may be fed into the chipper chute.

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.

Figure 17  
Figure 18  
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.
