SPECIAL NOTE: Exposure to vibrations through prolonged use of gasoline powered hand tools could cause blood vessel or nerve damage in the

fingers, hands, and joints of people prone to circulation disorders or abnormal swelling. Prolonged use in cold weather has been linked to blood

vessel damage in otherwise healthy people. If symptoms occur such as numbness, pain, loss of strength, change in skin color or texture, or loss of

feeling in the fingers, hands or joints, discontinue use of this tool and seek medical attention. A reduced vibration system does not guarantee avoidance

of these problems. Users who operate power tools on a regular basis must closely monitor their physical condition and the condition of this tool.

WARNING: OVERFILLING OIL CRANKCASE MAY CAUSE

SERIOUS PERSONAL INJURY. Check and maintain the proper oil level in the crank case; it is important and cannot be

overemphasized. Check the oil before each use while the engine is cold and change it as needed. See Changing the Oil.

RECOMMENDED OiL TYPE

Using the proper type and weight of oil in the crankcase is extremely important. Check oil before each use while the engine is cold and change the oil per the Maintenance Schedule. Failure to use the correct oil, or using

dirty oil, can cause premature engine wear and failure.

Use a high-quality SAE 30 weight oil of API (American Petroleum Institute) service class SF, SG, SH.

RECOMMENDED FUEL TYPE Old fuel is the primary reason for improper unit performance. Be sure to use

fresh, clean, unleaded gasoline. NOTE: This is a four-cycle engine. In order to avoid damage to the unit, do

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 or form acids when stored.

Use fresh fuel (less than 60 days old), when using alcohol-blended fuel. Using Blended Fuels

_ WARNING: Add fuel in a clean, well ventilated outdoor area. Wipe |

_ WARNING: Gasoline is extremely flammable. Ignited vapors may

If you choose to use a blended fuel, or its use is unavoidable, follow recommended precautions:

• Always use fresh unleaded gasoline

• Use the fuel additive STA-BIL@ or an equivalent

• Drain tank and run the engine dry before storing unit Using Fuel Additives The use of fuel additives, such as STA-BIL® Gas Stabilizer or an equivalent,

will inhibit corrosion and minimize the formation of gum deposits. Using a fuel additive can keep fuel from forming harmful deposits in the carburetor

for up to six (6) months. Add 0.8 oz. (23 ml.) of fuel additive per gallon of fuel according to the instructions on the container. NEVER add fuel additives

OPERATING TiPS

the unit, make sure blower tubes are in place before you operate the unit.

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. 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 cruise control (Fig. 15) 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.

safety glasses at all times when operating this unit. Wear a face mask or dust mask in dusty locations.

Before operating the unit, stand in the operating position (Fig. 20). 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.

Ifthe 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.

MAINTENANCESCHEDULE

AiR FILTER MAINTENANCE

Cleaning the Air Filter Clean and re-oil the air filter per the Maintenance Schedule. It is an

important item to maintain. Failure to maintain your air filter properly can result in poor performance or can cause permanent damage to your engine.

1. Open the air filter cover. Push the locking tab on the under side of the cover inward. Then pull the air filter cover out and up. (Fig. 23).

_ ARNING: To avoid serious personal injury, always turn the

unit off and allow it to cool before you clean or service it.

_ WARNING: Wear gloves to prevent injury when handling unit.

Change the oil per the Maintenance Schedule. Change the oil while the

engine is still warm. The oil will flow

freely and carry away more impurities.

1. Remove the oil fill plug.

2. Pour the oil out of the oil fill hole and into a container by tipping

the unit to the side (Fig. 21). Allow ample time for complete

drainage.

3. Wipe up any oil residue on the unit and clean up any oil that

may have spilled. Dispose of

the oil according to Federal, Fig. 21

State and local regulations.

4. Tilt the unit 30° to the side (Fig. 22).

5. Refill the crankcase with 3.04 fluid ounce (90 ml) of SAE 30 SF,SG, SH oil.
