32°F

Colder

5W30

Warmer

•

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
dipstick. Capacity is approximately 20 oz. Be
careful 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 little 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 container.
Gasoline that has been sitting for any period
longer than four weeks should be considered
stale.

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 unit before it can be
restarted. Refer to SERVICE AND
ADJUSTMENT section.

Vacuum without a muffler or tamper with
the exhaust system. Damaged mufflers
or spark arresters could create a fire
hazard.

NOTE: If the foam filter is torn or damaged in any
way, replace it.
WARNING: WARNING: Temperature of
muffler and nearby areas may exceed
150o F(65oC). Avoid these areas.

CLEAN ENGINE
•
•

Clean engine by removing dirt and debris with a
cloth or brush.
Frequently remove grass clippings, dirt, and
debris from cooling fins, air intake screen, levers,
and linkage. This will help ensure adequate
cooling and engine speed.

SERVICE AND ADJUSTMENTS
WARNING: Do not at any time make any
adjustment to the unit without first
stopping engine and disconnecting
spark plug wire.

WARNING: Do not attempt to alter the
engine speed by tampering with the
engine’s governor linkage. Doing so
could result in serious personal injury
and damage to the engine. The engine
RPM has been set at the factory.

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. See Figure 14.

REMOVING THE FLAIL SCREEN

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.

•

If the discharge area becomes clogged, remove the
flail screen and clean area as follows.
•

•

Stop the engine. Make certain the chipper
shredder vacuum has come to a complete stop.
Disconnect and ground the spark plug wire
before unclogging the discharge chute.

STORAGE
NOTE: Fuel stabilizer is an acceptable alternative in
minimizing the formation of fuel gum deposits during
storage.

Prepare your Craftsman Yard Vacuum for storage at
the end of the season or if the unit will not be used for
30 days or longer. A yearly check-up by your local
Sears Service Center is a good way to ensure that the
unit runs properly next season.

•

Add stabilizer to gasoline in fuel tank or storage
container.
• Always follow the mix ratio found on stabilizer
container.
• Run engine at least 10 minutes after adding
stabilizer to allow the stabilizer to reach the
carburetor.
• Do not drain the gas tank and carburetor if using
fuel stabilizer. Drain all the oil from the
crankcase (this should be done after the engine
has been operated and is still warm) and refill the
crankcase with fresh oil.
If you have drained the fuel tank, protect the inside of
the engine as follows:

Yard Vacuum
•
•
•
•

Clean the equipment thoroughly.
Wipe equipment with an oiled rag to prevent rust.
Use a light oil or silicone to wipe.
Service the engine following instructions below.
Store unit in a clean, dry area. Do not store next to
corrosive materials such as fertilizer.

Engine
IMPORTANT: It is important to prevent gum deposits

from forming in essential fuel system parts such as
the carburetor, fuel filter, fuel hose, or tank during
storage. Also, 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.

•

Other
•

To avoid engine problems, the fuel system should be
emptied before storage of 30 days or longer. Follow
these instruction:
•
•
•
•

Remove spark plug, pour approximately 1/2
ounce (approximately one tablespoon) of engine
oil into cylinder and crank slowly to distribute oil.
Replace spark plug.

•

Drain the fuel tank.
Start the engine and let it run until the fuel lines
and carburetor are empty.
Drain carburetor.
Never use engine or carburetor cleaner products
in the fuel tank or permanent damage may occur.

•

Do not store gasoline from one season to
another.
Replace the gasoline can if it starts to rust. Rust
and/or dirt in the gasoline will cause problems.
Store unit in a clean, dry area. Do not store next
to corrosive materials, such as fertilizer.

NOTE: If storing in an unventilated or metal storage
shed, be certain to rustproof the equipment by coating with a light oil or silicone.
