SAFETY INFORMATION

SYMBOL MEANING
• KEEP BYSTANDERS AWAY
WARNING:
Keep all bystanders, especially children and pets, at least 50 feet (15 m)
from the operating area.
• HOT SURFACE
WARNING:
Do not touch a hot engine. These parts get extremely hot from
operation and may cause severe burns. When the unit is turned off, the engine will
remain hot for a short time.
• BLOWERS – ROTATING IMPELLER BLADES CAN CAUSE SEVERE INJURY
WARNING:
Stop the engine and allow the impeller to stop before installing or
changing tubes, or before cleaning or performing any maintenance.
ASSEMBLY INSTRUCTIONS
ASSEMBLING THE UNIT
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.
BLOWER ASSEMBLY
Installing the Upper Blower Tube
1. Align the bump on the end of the upper
blower tube with the bump slot on the bottom
end of the blower outlet (Fig. 1).
2. Insert the upper blower tube into the blower
outlet (Fig. 1).
3. Twist the upper blower tube clockwise until it
locks into place (Fig. 1).
Installing the Lower Blower Tube
1. Align the bump slot on the top end of the lower
blower tube with the bump on the end of the
upper blower tube (Fig. 2).
2. Place the lower blower tube onto the upper
blower tube (Fig. 2).
3. Twist the lower blower tube clockwise until
tight (Fig. 2).
VACUUM ASSEMBLY
Removing the Upper Blower Tube
1. Hold the unit firmly.
2. Insert a flathead screwdriver into the tube
lock. Twist the screwdriver counterclockwise
1/4 turn and hold (Fig. 3).
3. Grasp the upper blower tube and twist it
counterclockwise (Fig. 3).
4. Pull the upper blower tube from the blower
outlet.
Removing the Lower Blower Tube
1. Hold the upper blower tube firmly.
2. Grasp the lower blower tube and twist it counterclockwise until the lower blower
tube unlocks from the upper blower tube.
3. Remove the lower blower tube from the upper 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. 4). 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. 5). 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. 6).
3. Align the arrow on the lower vacuum tube with the arrow on the upper vacuum
tube (Fig. 7).
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. 8)
2. Insert the vacuum elbow into the blower and turn clockwise until it locks into
place. (Fig. 8)
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. 9)
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.

OIL AND FUEL INFORMATION

OIL AND FUEL MIXING INSTRUCTIONS
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.
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.
