GAS AND OIL FILL-UP
Oil (one 20-oz. bottle shipped with unit)
Only use high quality detergent oil rated with API ser­
vice classification SF, SG, or SH. Select the oil’s SAE
viscosity grade according to the expected operating
temperature. Follow the chart below.
Colder 32° F Warmer
5W30 SAE 30
Oil Viscosity Chart
NOTE: 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.
• Remove oil fill dipstick.
• With the Yard Vacuum on level ground, use a
funnel to fill engine with oil to FULL mark on dip­
stick. Capacity is approximately 20 oz. Be care­
ful not to overfill. Overfilling will cause the
engine to smoke profusely and will result in poor
engine performance. The oil bottle packaged
with your Yard Vacuum contains 20 oz. of oil.
• Check the oil level making certain not to rub the
dipstick along the inside walls of the oil fill tube.
This would result in a false dipstick reading.
Refill to FULL mark on dipstick, if necessary.
Replace dipstick and tighten.
• Check oil level three times prior to starting
engine to be certain you’ve gotten an accurate
dipstick reading. Running the engine with too lit­
tle oil can result in permanent engine damage.
Gasoline
•
Remove fuel cap from the fuel tank.
• Make sure the container from which you will
pour the gasoline is clean and free from rust or
foreign particles. Never use gasoline that may
be stale from long periods of storage in its con­
tainer. Gasoline that has been sitting for any
period longer than four weeks should be consid­
ered stale.
• Fill fuel tank with clean, fresh, unleaded regular,
unleaded premium or reformulated automotive
gasoline only. DO NOT use Ethyl or high octane
gasoline. Do not use gasoline containing
METHANOL. Replace fuel cap.
• 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 STOR­
AGE section for additional information.
A WARNING: Never fill the fuel tank indoors,
with engine running or while engine is hot.
Do not smoke when filling fuel tank. Do not
fill closer than 1/2 inch from the top of the
fuel tank to prevent spills and to allow for
fuel expansion.
• Check the fuel level periodically to avoid running
out of gasoline while operating the Yard Vac­
uum. If the unit runs out of gas as it is chipping, it
may be necessary to unclog the unit before it
can be restarted. Refer to SERVICE AND
ADJUSTMENT section.
TO STOP ENGINE
• Move throttle control lever to STOP position.
• Disconnect spark plug wire and ground it to the
post to prevent accidental starting while the
equipment is unattended.

5a. When temperature is above 32 degrees F;
• Move throttle control / choke level to FAST

restart a warm engine after a short shut­
down. See Figure 7.
