ASSEMBLING THE UNIT

BLOWER ASSEMBLY

Installing the Blower Tube

1. Align the bump on the end of the blower tube

with the bump slot on the bottom end of the
blower outlet (Fig. 1).

2. Insert the bump on the blower tube into the

bump slot on the blower outlet (Fig. 1).

3. Twist the blower tube clockwise inside the

blower outlet until the bump locks into place
(Fig. 2).

Installing the Nozzle

1. Align the bump on the end of the blower tube

with the bump slot on the top end of the nozzle
(Fig. 3).

2. Insert the bump on the blower tube into the

bump slot on the nozzle (Fig. 3).

3. Twist the nozzle clockwise over the blower

tube until tight (Fig. 4).

VACUUM ASSEMBLY

Removing the Blower Tube

1. Hold the unit firmly.

2. Insert a flathead screwdriver into the tube lock

and twist the screwdriver counterclockwise
1/4 turn and hold it there (Fig. 5).

3. While holding the screwdriver in a

counterclockwise position, grasp the blower
tube and twist it counterclockwise (Fig. 5).

4. Pull the blower tube from the blower outlet.

Removing the Nozzle

1. Hold the blower tube firmly.

2. Grasp the nozzle and twist it counterclockwise

until the nozzle unlocks from the blower tube
(Fig. 6).

3. Remove the nozzle from the blower tube.

Installing the Vacuum Tubes

1. Locate the hole in the impeller door. The door

lock tab is recessed in the hole toward the
front of the blower (Fig. 7). Insert a flat head
screwdriver, into the hole and press the door
lock tab in and lift the door to release the lock.

2. While holding the impeller door open, align the

upper vacuum tube's three (3) slots with the
impeller intake’s three (3) lock tabs (Fig. 8).
Insert the upper vacuum tube into the impeller
intake and twist the upper vacuum tube
clockwise with both hands until the lock tabs
snap into place (Fig. 9).

3. Align the arrow on the lower vacuum tube with

the arrow on the upper vacuum tube (Fig. 10).

NOTE:

The arrows must align properly to
install the vacuum tubes correctly.

4. Grasp the lower vacuum tube firmly with both hands and push the lower vacuum

tube into the upper vacuum tube. Turn the lower vacuum tube clockwise until it
snaps into place and locks. The dot on the lower tube aligns with the dot on the
upper tube when properly assembled.

NOTE:

Use both hands during this assembly to fit the parts together tightly.

NOTE:

The flat area on the upper vacuum tube should face the handle when
installed correctly.

VACUUM BAG ASSEMBLY

Installing the Vacuum Elbow onto the Blower

1. While facing the front of the unit, hold the keyed end of the vacuum elbow in the

left hand and the flared end in the right hand. Align the lock tabs on the keyed end
with the lock tabs on the blower outlet. (Fig. 11)

2. Insert the vacuum elbow into the blower and turn clockwise until it locks into

place. (Fig. 11)

Inserting the Vacuum Elbow into the Bag

1. Locate the small opening in the vacuum bag. Insert the flared end of the vacuum

elbow approximately 4 in. inside the small opening. (Fig. 12)

2. Pull the end of the cinch strap to secure the small opening of the bag around the

vacuum elbow. Tighten the cinch strap so that the bag has limited movement
along the elbow, but will not slip off the flared end.

ASSEMBLY INSTRUCTIONS

WARNING:

To prevent serious personal injury, stop the engine and allow the impeller to stop before

attaching or removing tubes.

WARNING:

To prevent serious personal injury or damage to the unit, make sure the blower tubes, or

vacuum tubes and the vacuum bag, are in place before you operate the unit.

OIL AND FUEL MIXING INSTRUCTIONS

Old and/or improperly mixed fuel are the main reasons for the unit not running properly. Be sure to use fresh, clean
unleaded fuel. Follow the instructions carefully for the proper fuel/oil mixture.

Definition of Blended Fuels

Today's fuels are often a blend of gasoline and oxygenates such as ethanol, methanol, or MTBE (ether). Alcohol-
blended fuel absorbs water. As little as 1% water in the fuel can make fuel and oil separate. It forms acids when
stored. When using alcohol-blended fuel, use fresh fuel (less than 30 days old).

Using Blended Fuels

If you choose to use a blended fuel, or its use is unavoidable, follow recommended precautions:

• Always use the fresh fuel mix explained in your operator's manual

• Use the fuel additive STA-BIL® or an equivalent

• Always agitate the fuel mix before fueling the unit

• Drain the tank and run the engine dry before storing the unit

Using Fuel Additives

The bottle of 2-cycle oil that came with your unit contains a fuel additive which will help inhibit corrosion and minimize
the formation of gum deposits. It is recommended that you use our 2-cycle oil with this unit. If unavailable, use a good
2-cycle oil designed for air-cooled engines along with a fuel additive, such as STA-BIL® Gas Stabilizer or an
equivalent. Add 0.8 oz. (23 ml) of fuel additive per gallon of fuel according to the instructions on the container. NEVER
add fuel additives directly to the unit's fuel tank.

Thoroughly mix the proper ratio of 2-cycle engine oil with unleaded gasoline in a separate fuel can. Use a 40:1 fuel/oil
ratio. Do not mix them directly in the engine fuel tank. See the table below for specific gas and oil mixing ratios.

NOTE:

One gallon (3.8 liters) of unleaded gasoline mixed with one 3.2 oz. (95 ml) bottle of 2-cycle oil makes a 40:1
fuel/oil ratio.

NOTE:

Dispose of the old fuel/oil mix in accordance with federal, state and local regulations.

*WARNING: DO NOT USE E85 FUEL IN THIS UNIT.

It has been proven that fuel containing greater than 10% ethanol will likely
damage this engine and void the warranty.

WARNING:

Gasoline is extremely flammable. Ignited vapors may

explode. Always stop the engine and allow it to cool before filling the
fuel tank. Do not smoke while filling the tank. Keep sparks and open
flames at a distance from the area.

CAUTION:

For proper engine operation and maximum reliability, pay strict attention to the oil and fuel

mixing instructions on the 2-cycle oil container. Using improperly mixed fuel can severely damage the engine.

WARNING:

Remove fuel cap slowly to avoid injury from fuel spray.

Never operate the unit without the fuel cap securely in place.
