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 60 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
• 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 to Federal, State and Local regulations.
FUELING THE UNIT
1. Remove the fuel cap.
2. Place the gas container’s spout into the fill hole on the fuel
tank (Fig. 10) and fill the tank.
NOTE: Do not overfill the tank.
3. Wipe up any fuel that may have spilled.
4. Reinstall the fuel cap.
5. Move the unit at least 30 ft. (9.1 m) from the fueling source and site before starting the engine.
NOTE: Dispose of the old fuel mixture in accordance to Federal, State and Local regulations.

WARNING:
Add fuel in a clean, well ventilated outdoor area. Wipe up any spilled fuel
immediately. Avoid creating a source of ignition for spilt fuel. Do not start the engine until
fuel vapors dissipate.
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.

STARTING INSTRUCTIONS
STOPPING INSTRUCTIONS
1. Release your hand from the trigger. Allow the engine to cool
down by idling.
2. Press the On/Off switch in the OFF (O) position and hold until the engine comes to a complete stop
(Fig. 10, A).
STARTING/STOPPING INSTRUCTIONS
1. Mix gas with oil. Fill fuel tank with fuel/oil mixture. See
Oil and Fuel Mixing Instructions.
NOTE: There is no need to turn the unit on. The On/Off Switch
is in the ON ( I ) position at all times (Fig. 11, A).
2. Fully press and release the primer bulb 10 times,
slowly. Some amount of fuel should be visible in the
primer bulb and fuel lines (Fig. 12). If you can’t see fuel
in the bulb, press and release the bulb as many times
as it takes until you can see fuel in it.
3. Place the blue choke lever in Position 1 (Fig. 12).
4. Squeeze and hold the trigger (Fig. 11, A).
5. Press and hold the trigger lock (Fig. 11, B).
6. Release the trigger.
7. Release the trigger lock.
NOTE: The trigger lock should hold the trigger in the pressed
position (Fig. 11, B). If not, repeat steps 4–7.
8. Crouch in the starting position (Fig. 13) and pull the
starter rope briskly 5 times.
9. Place the blue choke lever in Position 2 (Fig. 12).
10. Pull the starter rope briskly until the engine starts.
11. Keep the throttle squeezed and allow the engine to
warm up for 15 to 30 seconds.
NOTE: Engine may take longer to warm up and reach
maximum operating speed at colder temperatures.
NOTE: Unit is properly warmed up when engine
accelerates without hesitation.
12. Once the engine is warmed up, place the blue choke
lever in Position 3 (Fig. 12). The unit is ready for use.
IF... the engine hesitates, return the blue choke lever to
Position 2 (Fig. 12) and continue warm-up.
IF... the engine does not start, go back to step 2.
IF... the engine fails to start after a few attempts, place the
blue choke lever in Position 3 and squeeze the throttle
control. Pull the starter rope briskly 3 to 8 times. The
engine should start. If not, repeat.
IF WARM... If the engine is already warm, start the unit
with the blue choke lever in Position 2. After the unit
starts, move the blue choke lever to Position 3.
WARNING:
Avoid accidental starting. Make sure you are in the starting position when
pulling the starter rope (Fig. 12). To avoid serious injury, the operator and unit must be
in a stable position while starting.
To avoid serious personal injury, make sure that the blower tube is locked in place or
firmly installed.
WARNING:
Operate this unit only in a well- ventilated outdoor area. Carbon
monoxide exhaust fumes can be lethal in a confined area.

OPERATING INSTRUCTIONS
ADJUSTING THE SUSPENSION SYSTEM
1. Place the unit’s shoulder supports over the shoulders while
the unit is behind you.
2. Close the suspension system’s waist support by sliding the
waist support clips together (Fig. 14, A).
NOTE: Make sure the weight of the unit is supported on the hips
by the waist support (Fig. 15, A).
3. If weight is not on hips, loosen the shoulder supports (Fig.
16, A) and pull the waist support handle (Fig. 15, B) to
tighten. Adjust until the unit’s weight rests on the hips.
4. Pull the shoulder support handles to tighten the shoulder
supports (Fig. 14, B).
Releasing the Suspension System
1. To release the shoulder supports, pull up on bottom tab of
the shoulder support buckles (Fig. 16, A).
2. Squeeze the top and bottom of the waist support clips to
release the waist support (Fig. 16, B).
HOLDING THE BLOWER
Before operating the unit, stand in the operating position (Fig. 17).
Check for the following:
•
Operator is wearing proper clothing, such as boots, safety
glasses or goggles, ear/hearing protection, gloves, long pants
and long sleeve shirt.
• If the conditions are dusty, the operator is wearing a dust
mask or face mask.
• The unit is in good working condition.
• The tubes are in place and secure.
OPERATING TIPS
• Assure the unit is not directed at anybody or any loose debris
before starting the unit.
• Verify that the unit is in good working condition. Make sure the tubes are in place and secure.
• Always hold the unit securely when operating.
• To reduce the risk of hearing loss associated with sound level(s), hearing protection is required.
WARNING: To avoid serious personal injury,
wear goggles or safety glasses at all times when
operating this unit. Wear a face mask or dust
mask in dusty locations.
Fuel Can Spout
Fuel Tank
• Operate power equipment only at reasonable hours— not
early in the morning or late at night when people might be
disturbed. Comply with times listed in local ordinances. Usual
recommendations are 9:00 am to 5:00 pm, Monday through
Saturday.
• To reduce noise levels, limit the number of pieces of
equipment used at any one time.
• To reduce noise levels, operate power blowers at the lowest
possible speed to do the job.
• Check your equipment before operation, especially the
muffler, air intakes and air filters.
• Use rakes and brooms to loosen debris before blowing.
• In dusty conditions, slightly dampen surfaces or use a mister attachment when water is available.
• Conserve water by using power blowers instead of hoses for many lawn and garden applications,
including areas such as screens, patios, grills, porches, and gardens.
• Watch out for children, pets, open windows or freshly washed cars, and blow debris safely away.
• Use the full blower nozzle extension so the air stream can work close to the ground.
• Clean up after using blowers and other equipment. Dispose of debris appropriately.
• Use the trigger lock (Fig. 11, B) to keep the trigger depressed while operating to make continuous
operation easier.
APPLICATIONS
1 Use the blower for trees, shrubs, flower beds and hard-to-clean areas.
2. Use the unit around buildings and for other normal cleaning procedures.
3. Use the blower around walls, overhangs, fences and screens.
WARNING:
To prevent serious personal injury
or damage to the unit, make sure blower tubes
are in place before you operate the unit.
