PREPARATION  
and equipment. Move machine to another  
area. Wait 5 minutes before starting the  
engine.  
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.  
3
i. Never store the machine or fuel container  
inside where there is an open flame, spark,  
or pilot light (e.g. furnace, water heater,  
space heater, clothes dryer, etc.)  
j. To reduce a fire hazard, keep machine free  
of grass, leaves, or other debris build-up.  
Clean up oil or fuel spillage and remove any  
fuel soaked debris.  
9. Never operate without either the inlet nozzle or  
optional hose attachment properly attached to the  
machine. Never attempt to attach or change either  
attachment while the engine is running.  
10. Keep all guards, deflectors and safety devices in  
place and operating properly.  
11. Keep your face and body back and to the side of  
the chipper chute while feeding material into the  
machine to avoid accidental kickback injuries.  
12. Never operate this machine without good visibility  
or light. Always be sure of your footing and keep a  
firm hold on the handles.  
13. Do not operate this machine on a gravel surface.  
14. Do not operate this machine while under the  
influence of alcohol or drugs.  
15. Muffler and engine become hot and can cause a  
burn. Do not touch.  
k. Allow machine to cool at least 5 minutes  
before storing.  
OPERATION  
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.  
16. Never pick up or carry machine while the engine is  
running.  
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.  
MAINTENANCE AND STORAGE  
1. Never tamper with safety devices. Check their  
proper operation regularly.  
4. If the impeller strikes a foreign object or if your  
machine should start making an unusual noise or  
vibration, immediately shut the engine off. Allow the  
impeller to come to a complete stop. Disconnect  
the spark plug wire, ground it against the engine  
and perform the following steps:  
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. 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.  
5. Maintain or replace safety and instruction labels, as  
necessary.  
a. Inspect for damage.  
b. Repair or replace any damaged parts.  
c. Check for any loose parts and tighten to  
assure continued safe operation.  
5. Do not allow an accumulation of processed  
material to build up in the discharge area. This can  
prevent proper discharge and result in kickback of  
material through the feed opening.  
6. Do not attempt to shred or chip material larger than  
specified on the machine or in this manual.  
Personal injury or machine damage could result.  
7. Never attempt to unclog either the feed intake or  
discharge opening while the engine is running.  
Shut the engine off, wait until all moving parts have  
stopped, disconnect the spark plug wire and  
ground it against the engine before clearing debris.  
8. Never operate without vacuum bag and discharge  
chute properly attached to the machine. Never  
empty or change vacuum bag while the engine is  
running. Zippered end of vacuum bag must be kept  
closed at all times during operation.  
6. Follow this manual for safe loading, unloading,  
transporting, and storage of this machine.  
7. Never store the machine or fuel container inside  
where there is an open flame, spark or pilot light  
such as a water heater, furnace, clothes dryer, etc.  
8. Always refer to the operator’s manual for proper  
instructions on off-season storage.  
9. If the fuel tank has to be drained, do this outdoors.  
10. Observe proper disposal laws and regulations for  
gas, oil, etc. to protect the environment.

SECTION 4: OPERATING YOUR YARD VACUUM  
WARNING: The operation of the Yard  
Vacuum can result in foreign objects  
being thrown into the eyes, which can  
damage your eyes severely. Always wear  
the safety glasses provided with this unit  
or eye shields before chipping or blowing  
and while performing any adjustments or  
repairs.  
The throttle control is located on the engine. Move

Nozzle/Hose  
Vac Handle  
(Bottom Position)  
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.

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 the  
conditions. Move the height adjustment levers forward  
or backward to adjust the nozzle upwards or  
downwards. Make sure both levers are in the same  
position. See Figure 10.  
NOTE: In general, raise the nozzle height to vacuum a  
thick layer of leaves or to operate with the blower chute  
and lower the nozzle height for smoother surfaces.
