ATTACH FLEX TUBE
Put the hose clamp(C) on the flex tube before connect-
ing the flex tube and the fan’s outlet tube together.

Connect the flex tube (B) to the fan’s outlet tube (A) (Fig.
1) with a hose clamp (C) (Fig. 2) and tighten securely
(Fig. 2).

ATTACH OPERATING TUBE
NOTE: 
keep the throttle cable as straight as possible

when connecting the blower tubes.

1. Place the unit on flat surface during assembly. Insure

screw mechanism of clamp is positioned away from
operator.

2. Put the hose clamp (C) on the flex tube and the oper-

ating tube before connecting them together. 

3. Turn the throttle linkage mark (D) so it aligns with the

throttle handle (F) (Fig.3). Insert the operating tube (E)
into the flex tube (B) (Fig. 3) and then tighten securely
with a hose clamp (G)(Fig. 4).

OIL AND FUEL INFORMATION

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,
(less than 60 days old) 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 oxy-
genates 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 and leads to
formation of acids during storage. When using alcohol-
blended fuel, use fresh fuel.

Using Blended Fuels
If you choose to use a blended fuel, or its use is unavoid-
able, follow recommended precautions:

• Always use the fresh fuel mix explained in your opera-

tor's manual

• 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 mini-
mize 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.

To Obtain Correct Fuel Mix:
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 to

Federal, State and Local regulations.

For proper engine
operation and maxi-

mum 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.

Gasoline is
extremely flamma-

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

WARNING:

Remove fuel cap
slowly to avoid injury

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

WARNING:

Add fuel in a clean,
well ventilated out-

door area. Wipe up any spilled fuel immedi-
ately. Avoid creating a source of ignition for
spilled fuel. Do not start the engine until fuel
vapors dissipate.
