OIL AND FUEL INFORMATION
OIL AND FUEL MIXING INSTRUCTIONS
Old and/or impr
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 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 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 accor

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.

STARTING/STOPPING INSTRUCTIONS

system with
cantly reduces the effort required to start the engine.
You must pull the starter rope out far enough to hear
the engine attempt to star
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.
4. With the unit on the ground, hold the top assist handle
and step on the bottom of the frame with foot. (Figure
12)
5. Pull starter rope 4-6 times-if unit does not start move
choke lever to position 2 and pull 4-6 more times
(Fig. 13). Wait 10 sec. after unit starts then move
choke lever to position 3. (Fig.14)
6. Press trigger to run.
NOTE: If engine fails to start after repeated attempts,
refer to Troubleshooting section.
NOTE: Always pull starter rope straight out. Pulling
starter at an angle will cause rope 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 (G) on the carburetor (Figure 15).
