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 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 and leads to
formation of acids during storage. When using alcoholblended fuel, use fresh fuel.
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
• 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.
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 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.

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.
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 outdoor area. Wipe up any spilled fuel immediately. Avoid creating a source of ignition for
spilled fuel. Do not start the engine until fuel
vapors dissipate.

NOTE: The unit uses the Spring AssistTMstarting sys-
tem, which significantly reduces the effort required to
start the engine. You must pull the starter rope out far
enough to hear the engine attempt to start. There is
no need to pull the rope briskly--there is no harsh
resistance when pulling. Be aware that this starting
method is vastly different from (and much easier than)
what you may be used to.
5. Move choke lever to “2” (Fig.13)
6. Pull starter rope again 1~6 times (Fig.14)
7. The engine should start. After 30 sec. Move choke to
“3”.(Fig.15)
8. Squeeze throttle and release to disengage lock ; Unit
is now at idle.(Fig.9)
NOTE: If engine fails to start after repeated attempts,
r
efer to Troubleshooting section.
NOTE: Always pull starter rope straight out. Pulling
starter at an angle will cause r
ope to rub against the eyelet. This friction will cause the rope to fray and wear more
quickly. Always hold starter handle when rope retracts.
Never allow rope to snap back from extended position.
This could cause rope to snag or fray and also damage
the starter assembly.
IMPORTANT IDLING INFORMATION
In some cases due to operating conditions (altitude, temperature etc.) your blower may need a slight adjustment
to the idle speed.
After warm up, If unit does not Idle after restarting 2
times, follow these steps to adjust idle.
1. Locate the idle adjustment screw (E) on the carbure-
tor (Figure 16).
2. Using a Phillips or slotted screwdriver - turn screw
