  USING THE CRUISE CONTROL
1.  Once the engine has been started and warmed up, squeeze 

the trigger to accelerate the unit as needed (Fig. 1).

2.  For longer periods of operation and to eliminate possible 

fi nger fatigue, move the cruise control toward the 
FAST position to incrementally increase or maintain the unit’s 
engine speed (Fig. 1).  When the cruise control is pressed, the 
trigger will recede into the handle.

3.  To decrease engine speed, move the cruise control to the 

SLOW position and the trigger will return to the idle position 
(Fig. 1).

Always hold the unit securely when operating. 

• 

To reduce the risk of hearing loss associated with sound 
level(s), hearing protection is required.

• 

Operate power equipment only at reasonable hours. Comply 
with times listed in local ordinances. Usual recommendations 
are 9:00 am to 5:00 pm, Monday through Saturday.

• 

To reduce noise levels, operate power blowers at the lowest possible speed to do the job and limit 
the total number of pieces of power equipment used at any one time.

• 

Check unit before operating, especially muffl er, air intakes and air fi lters, for debri and possible 
blockages.

• 

Use rakes and brooms to loosen debris before blowing.

• 

In dusty conditions, slightly dampen surfaces.

• 

Conserve water by using power blowers instead of hoses for many lawn and garden applications, 
including cleaning debri from 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 closer to the ground.

• 

Clean up after using blowers and other equipment. Dispose of debris appropriately.

• 

Use the cruise control to make continuous operation easier.

• 

Use the blower for trees, shrubs, fl ower beds and hard-to-clean areas.

• 

Use the unit around buildings and for other normal cleaning procedures.

• 

Use the blower around walls, overhangs, fences and screens. 

Be sure to use fresh, clean unleaded fuel and follow instructions carefully for proper fuel/oil mixture.

Today’s fuels are often a blend of gasoline and oxygenates such as ethanol, methanol, or MTBE (ether) 
which absorb water. Use fuel within 30 days of purchase. Blended fuels older than 30 days will affect 
the performance and life of the engine.

Using Blended Fuels
If the use of blended fuel is unavoidable, follow recommended precautions:

• 

Always use the fresh fuel mix explained in the 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
 It is recommended to use the manufacturers 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.

Mixing The Fuel
Thoroughly mix the proper ratio of 2-cycle engine oil with unleaded fuel in a separate fuel can. Use a 
40:1 fuel/oil ratio. Do not mix them directly in the engine fuel tank.
 IF... 

the unit came with a bottle of 2-cycle oil; pour the entire bottle into 1 gallon of gas and mix 
thoroughly.

NOTE: 

One gallon (3.8 liters) of unleaded fuel 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.

 Fuel containing greater than 10% ethanol will likely damage the engine and 

void the warranty.

 Gasoline is extremely fl ammable. Ignited vapors may explode. Always stop 

the engine and allow it to cool before fi lling the fuel tank. Do not smoke while fi lling the 
tank. Keep sparks and open fl ames at a distance from the area.

  Remove fuel cap slowly to avoid injury from fuel spray. Never operate the unit 

without the fuel cap securely in place.

 Add fuel in a clean, level and 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.

 MAINTENANCE SCHEDULE
Perform these required maintenance procedures at the frequency stated in the table. These 
procedures should also be a part of any seasonal tune-up.
NOTE: 

Some maintenance procedures may require special tools or skills. For these types of repairs 
call 1-800-800-7310 for more information.

NOTE: 

Please read the California/ EPA statement that came with the unit for a complete listing of 
terms and coverage for the emissions control devices, such as the spark arrestor, muffl er, 
carburetor, etc

Failure to maintain the air fi lter properly can result in poor 
performance or cause permanent damage to the engine.
1.  Open the air fi lter cover and remove the air fi lter (Fig. 5).
2.  Wash the fi lter in detergent and water. Rinse thoroughly and 

allow to dry.

3.  Apply clean SAE 30 motor oil to fi lter.
4. Squeeze 

fi lter to spread and remove excess oil.

5.  Replace air fi lter (Fig. 6).
NOTE: 

Operating unit without air fi lter WILL VOID warranty.

6.  Reinstall the air fi lter cover and press down until it snaps into 

place (Fig. 5). 

ADJUST IDLE SPEED SCREW
The idle speed of the engine is adjustable. An idle adjustment 
screw is between the air fi lter cover and the engine cover (Fig. 7).
NOTE: 

Careless adjustments can seriously damage your unit. 
An authorized service dealer should make carburetor 
adjustments.

If, after checking the fuel and cleaning the air fi lter, the engine still 
will not idle, adjust the idle speed screw as follows:
1.  Start the engine and let it run at a high idle for a minute to 

warm up. Refer to Starting/Stopping Instructions.

2.  Move the cruise control to the SLOW position and let 

the engine idle. If the engine stops, insert a small Phillips 
screwdriver in between the air fi lter cover and the engine 
cover (Fig. 7). Turn the idle speed screw in, clockwise, 1/8 of a 
turn at a time (as needed) until the engine idles smoothly.

Checking the fuel mixture, cleaning the air fi lter, and adjusting the 
idle speed should solve most engine problems. If not and all of the 
following are true:

• 

engine will not idle

• 

engine hesitates or stalls on acceleration

• 

there is a loss of engine power

take the unit to a qualifi ed service dealer.

REPLACING THE SPARK PLUG
