SAFETY INSTRUCTIONS
Safe Handling of Gasoline:
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.
Use only an approved gasoline container.1.
Never fill containers inside a vehicle or on a truck or trailer bed 2.
with a plastic liner. Always place containers on the ground
away from your vehicle before filling.
When practical, remove gas-powered equipment from 3.
the truck or trailer and refuel it on the ground. If this is not
possible, then refuel such equipment on a trailer with a
portable container, rather than from a gasoline dispenser
nozzle.
Keep the nozzle in contact with the rim of the fuel tank or 4.
container opening at all times until fueling is complete. Do not
use a nozzle lock-open device.
Extinguish all cigarettes, cigars, pipes and other sources of 5.
ignition.
Never fuel machine indoors.6.
Never remove gas cap or add fuel while the engine is hot or 7.
running. Allow engine to cool at least two minutes before
refueling.
Never over fill fuel tank. Fill tank to no more than ½ inch below 8.
bottom of filler neck to allow space for fuel expansion.
Replace gasoline cap and tighten securely.9.
If gasoline is spilled, wipe it off the engine and equipment. 10.
Move unit to another area. Wait 5 minutes before starting the
engine.
To reduce fire hazards, keep machine free of grass, leaves, or 11.
other debris build-up. Clean up oil or fuel spillage and remove
any fuel soaked debris.
Never store the machine or fuel container inside where there is 12.
an open flame, spark or pilot light as on a water heater, space
heater, furnace, clothes dryer or other gas appliances.

CHOKE CONTROL
The choke control is used to choke the carburetor and assist in starting
the engine.
Engine Off
CHOKE RUN
Although multi-viscosity oils (5W30, 10W30, etc.) improve starting
in cold weather, they will result in increased oil consumption when
used above 32°F. Check your engine oil level more frequently to avoid
possible engine damage from running low on oil.
Check the oil level making certain not to rub the dipstick along the 1.
inside walls of the oil fill tube. This would result in a false dipstick
reading. Refill to FULL mark on dipstick, if necessary. Capacity
is approximately 18 oz. Overfilling will cause the engine to smoke
profusely and will result in poor engine performance.
Replace oil fill dipstick and tighten.2.
Keep oil level at FULL. Running the engine with too little oil can 3.
result in permanent engine damage.
WARNING
Use extreme care when handling gasoline. Gasoline is extremely
flammable and the vapors are explosive. Never fuel machine indoors
or while the engine is hot or running. Extinguish cigarettes, cigars,
pipes, and other sources of ignition.
Gasoline
Remove fuel cap from the fuel tank.1.
Make sure the container from which you will pour the gasoline is 2.
clean and free from rust or foreign particles. Never use gasoline
that may be stale from long periods of storage in its container.
Gasoline that has been sitting for any period longer than four
weeks should be considered stale.
Fill fuel tank with clean, fresh, unleaded regular gasoline only. Do 3.
not use gasoline containing METHANOL. Replace fuel cap.
STARTER HANDLE
Used to start the engine.
GAS AND OIL FILL-UP
Oil (one bottle shipped with unit)
First Time Use
Remove oil fill dipstick. 1.
With the Yard Vacuum on level ground, use a funnel to empty 2.
entire contents of oil bottle provided into the engine.
Replace oil fill dipstick and tighten.3.
Subsequent Uses
Only use high quality detergent oil rated with API service classification
SF, SG, or SH. Select the oil’s SAE viscosity grade according to the
expected operating temperature. Follow the chart below:
Colder
5W30
SAE30
Warmer
CAUTION
Use 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.
CAUTION
To avoid engine problems, the fuel system should be emptied before
storage for 30 days or longer. Drain the gas tank, start the engine
and let it run until the fuel lines and carburetor are empty. Use
fresh fuel next season. See STORAGE Instructions for additional
information.
CAUTION
Never use engine or carburetor cleaner products in the fuel tank or
permanent damage may occur.
NOTE: Check the fuel level periodically to avoid running out of gasoline while operating the Yard Vacuum. If the unit runs out of gas as it
is chipping, it may be necessary to unclog the discharge area before it
can be restarted. Refer to SERVICE AND MAINTENANCE section.

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.
WARNING
Do not attempt to shred, chip, or vacuum any material larger than
specified on the machine or in this manual. Personal injury or damage
to the machine could result.
IMPORTANT: The flail screen is located inside the housing in the
discharge area. If the flail screen becomes clogged, remove and clean
as instructed in the SERVICE & MAINTENANCE section. For best
performance, it is also important to keep the chipper blade sharp.
WARNING
Do not at any time make any adjustments without first stopping
engine and disconnecting spark plug wire.
