CLEANING THE VACUUM BAG
1. Empty the bag after each use to avoid deterioration
and obstructing air flow, which will reduce the
performance of the vacuum.
2. Wearing eye protection and a dust mask, clean the
bag as needed. Turn the bag inside out after initial
emptying and vigorously shake out dust and debris.
3. Wash the bag once a year or more often if needed as
follows:
a. Remove the vacuum bag.
b. Turn bag inside out.
c. Hang up.
d. Hose down thoroughly.
e. Hang to dry.
f. Turn bag right side out.
CARBURETOR ADJUSTMENT
The idle speed of the engine is adjustable, the air filter
cover must be removed to do so. Only make adjustments
while the unit is assembled as a blower.
NOTE: Careless adjustments can seriously damage
your unit. An authorized service dealer should make
carburetor adjustments.
Check Fuel Mixture
Old and/or improperly mixed fuel is usually the reason
for the unit not running properly. Drain and refill the
tank with fresh, properly mixed fuel prior to making any
adjustments. Refer to Oil and Fuel Information Pg. 10.
Clean Air Filter
The condition of the air filter is importantto the operation
of the unit. A dirty air filter will restrict air flow and change
the air/fuel mixture. This is often mistaken for an out of
adjustment carburetor. Check the condition of the air filter
before adjusting the idle speed screw. Refer to Air Filter
Maintenance Pg. 14.
Adjust Idle Speed Screw
AWARNING: The unit will be running during idle
speed adjustments. Wear protective clothing
and observe all safety instructions to prevent
serious personal injury.
Also, Do not set unit on any surface except &
clean, hard area during these adjustments.
Debris such as gravel, sand, dust, grass, etc.
could be picked up by the air intake and thrown
out by the discharge opening, damaging unit,
property, or causing serious injury to bystanders
or operator.
If after checking the fuel mixture and cleaning the air filter
the engine still will not idle, adjust the idle speed screw
as follows.
1. Start the engine and let it run at a high idle for a
minute te warm up. See Starting/Stopping
Instructions, Pg. 15.
2. Shut the unit off and remove the air filter cover. See
steps 1 and 2 of Air Filter Maintenance Pg. 14.
.
4.
5.
6.
Restart the unit, release the throttle trigger and let the
engine idle. If the engine stops, insert a small phillips
or flat blade screwdriver into the idle speed screw
(Fig. 23). Turn the idle speed screw in, clockwise,
1/8 of a turn at a time (as needed) until the engine
idles smoothly.
If the engine seems to idle fast, turn the idle speed
screw counterclockwise 1/8 of a turn at a time (as
needed), to reduce idle speed.
Before reinstalling the air filter cover, Turn the idle
speed screw in, clockwise, 1/8 of a turn. This will
compensate for the speed reduction when the air
filter cover is back in place.
Reinstall the filter (Fig. 18, Pg. 15), air filter cover and
screws (Fig. 17, pg. 14).
Checking the fuel mixture, cleaning the air filter, and
adjusting the idle speed screw should solve most engine
problems.
If not and:
•The engine will not idle,
•The engine hesitates or stalls on acceleration,
• There is a loss of engine power,
have the unit checked and adjusted by an authorized
service dealer.

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, experience
indicates that 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 during storage.
To avoid engine problems, the fuel system should
be emptied before storage of 30 days or longer.
Follow these instructions:
1. Drain all fuel from the fuel tank and drain into a
container with the same 2-cycle fuel mixture. Do not
use fuel that has been stored for more than 60 days.
Dispose of the old fuel/oil mix in a safe manner and
use a fresh mix.
2. Start the engine and allow it to run until it stalls.
This ensures that all fuel has been drained from
the carburetor.
3. Under To Fuel Engine in the Operation section of this
manual, refer to the message labeled IMPORTANT,
regarding the use of gasohol in your engine.
Fuel stabilizer is an acceptable alternative in
minimizing the formation of fuel gum deposits during
storage. Add stabilizer to the gasoline in fuel storage
container. Follow the mix instructions found on
stabilizer container. Run engine at least five
(5) minutes after adding stabilizer.
CRAFTSMAN 40:1,2-cycle engine oil is already
blended with fuel stabilizer. If you do not use this
Craftsman oil, you can add a fuel stabilizer to your
fuel. NEVER add fuel stabilizer directly to the unit's
fuel tank.
4. Allow the engine to cool. Remove the spark plug and
put about 1 oz. (30 ml) of any high quality motor oil or
2-cycle oil into the cylinder. Pull the starter rope
slowly to distribute the oil. Reinstall the spark plug.
NOTE: Remove the spark plug and drain all of the oil
from the cylinder before attempting to start the unit after
storage.
5. Thoroughly clean the unit and inspect for any loose
or damaged parts. Repair or replace damaged parts
and tighten loose screws, nuts or bolts. The unit is
now ready for storage.
6. Store the unit in a dry, well ventilated area and out of
the reach of children.
