OiL AND FUEL MiXiNG iNSTRUCTiONS

The use of old and/or improperly mixed fuel is the most common cause of performance problems. Use only fresh, clean unleaded gasoline. Follow the instructions carefully for the proper gasoline/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, forming acids when stored. ALWAYS use fresh fuel (less than 30 days old).

NOTE: Dispose of old fuel according to federal, state and local

regulations.

Using Blended Fuels if using a blended fuel:

• Always use the fresh fuel mix explained in your operator's manual Use the fuel additive STA-BIL® or an equivalent

Always agitate the fuel mix before fueling the unit

Drain the tank and run the engine dry before storing the unit

_ WARNING: DO NOT USE E85 FUEL iN THiS UNIT. it |

Using Fuel Additives

The bottle of 2-cycle oil provided with this unit contains a fuel additive to help inhibit corrosion and minimize gum deposits. Always use the brand of 2-cycle oil that came with this unit. if this is unavailable, use a 2-cycle oil designed for air-cooled engines and mix it with a fuel additive, such as STA-BIL Fuel 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 NOTE: This unit comes with a 3.2 oz. bottle of 2-cycle oil. To obtain

FUELING THE UNiT

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.

WARNING: Remove the 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.

1. Position the unit with the fuel cap facing up.

2. Remove the fuel cap.

3. Place the fuel container spout into the fill hole on the fuel tank and fill the tank.

NOTE: Do not overfill the tank.

4. Wipe up any fuel that may have spilled.

5. Reinstall the fuel cap.

6. Move the unit at least 30 ft. (9.1 m) from the fuel container and the fueling site before starting the engine.

CAUTION-" For proper engine operation and maximum reliability, pay strict attention to the gasoline and oil mixing

instructions on the 2-cycle oil bottle. Using improperly mixed fuel can severely damage the engine.

Thoroughly mix the proper ratio of unleaded gasoline with 2-cycle engine oil. Do not mix them directly in the unit's fuel tank. Use a separate fuel can. Use a 40:1 gasoline/oil ratio. See the table below for specific gasoline and oil mixing ratios.

• Stand in the operating position (Fig. 7).

• Hold the shaft grip with the right hand. Keep the right arm slightly bent.

• Hold the handle with the left hand. Keep the left arm straight.

• Hold the unit at waist level,

• Keep the cutting head parallel to the ground so that it easily

contacts the grass without the need for bending over.

ADJUSTING THE TRIMMING LiNE LENGTH

This unit is equipped with a Bump Head. Trimming line can be released from the cutting head without stopping the engine.

To release more line, lightly tap the bump knob on the ground (Fig. 8) while operating the unit at high speed. For best results, tap the bump knob on bare ground or hard soil. Attempting to release line in tall grass may stall the engine.

NOTE: Do not rest the cutting head on the ground while the unit is

running.

Each time the bump knob is tapped, about 1 inch (25.4 mm) of trimming line is released.

NOTE: Always keep the trimming line fully extended. Line release

becomes more difficult when the cutting line gets shorter.

A blade in the cutting head shield will cut the line to the proper length if any excess line is released.

Fig. 7

Bump Knob

Fig. 8

CAUTION: Do not remove or alter the line cutting blade

assembly. Excessive line length will make the unit overheat. This may lead to serious personal injury or damage to the unit.

TiPS FOR BEST TRIMMING RESULTS

• Keep the cutting head parallel to the ground. Cut from left to right whenever possible. This improves the unit's

cutting efficiency and throws clippings away from the operator. Do not trim wet grass or weeds.

NOTE: Some line breakage will occur from:

Entanglement with foreign matter Normal line fatigue

Attempting to cut thick vegetation

Forcing the line into objects such as walls or fence posts

DECORATIVE TRIMMING

When trimming around trees, posts, fences, etc., rotate the whole unit so that the cutting head is at a 30 ° angle to the ground (Fig. 9).
