The bottle of 2-cycle oil contains a fuel additive which will help inhibit corrosion and minimize the formation of gum deposits. It is recommended to 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 fuel 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 for specific gas and oil mixing ratios.

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.

OIL AND FUEL INFORMATION

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.

WARNING:

and void the warranty.

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 choosing to use a blended fuel, or its use 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

CAUTION:

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

It has been proven that fuel containing greater than 10% ethanol will likely damage this engine

For proper engine operation and maximum reliability, pay strict attention to the oil and fuel

FUELING THE UNIT

1. Turn unit on its side, with the fuel cap facing up, and remove the fuel cap.

2. Place the gas container’s spout into the fill hole on the fuel tank and fill the tank. NOTE: Do not overfill the tank.

3. Wipe up any gasoline 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.

• The cutting head is parallel to the ground and easily contacts the grass

without the need to bend over

WARNING:

premature engine failure and / or unit damage.

Do not remove or alter the line cutting blade assembly. Excessive line length will cause

ADJUSTING TRIMMING LINE LENGTH

The Bump Head™ cutting head allows the release of trimming line without stopping the engine. To release more line, lightly tap the cutting head on the ground (Fig. 10) while operating the unit at high speed.

NOTE:

Always keep the trimming line fully extended. Line release becomes

more difficult when the cutting line gets shorter.

Each time the head is bumped, about 1 inch (25.4 mm) of trimming line releases. A blade in the cutting head shield will cut the line to the proper length if any excess line is released.

For best results, tap the bump knob on bare ground or hard soil. If attempting a line release in tall grass, the engine may stall. Always keep

Fig. 10

the trimming line fully extended. Line release becomes more difficult when the cutting line gets shorter. NOTE: Do not rest the Bump Head™ on the ground while the unit is running. Some line breakage will occur from:

• Entanglement with foreign matter

• Normal line fatigue

• Attempting to cut thick, stalky weeds

• Forcing the line into objects such as walls or fence posts

TIPS FOR BEST TRIMMING RESULTS

• Keep the cutting head parallel to the ground.

• Do not force the cutting head. Allow the tip of the line to do the cutting, especially along walls. Cutting with more than the tip will reduce cutting efficiency and may overload the engine.

• Cut grass over 8 inches (200 mm) by working from top to bottom in small increments to avoid premature line wear or engine drag.

• Cut from right to left whenever possible. Cutting to the left improves the unit's cutting efficiency. Clippings are thrown away from the operator.

• Slowly move the unit into and out of the cutting area at the desired height. Move either in a forward-backward or side-to-side motion. Cutting shorter lengths produces the best results.

• Trim only when grass and weeds are dry.

• The life of the cutting line is dependent upon:

• Following the trimming techniques

• What vegetation is being cut

• Where vegetation is cut

Fig. 11

For example, the line will wear faster when trimming against a foundation wall as opposed to trimming around a tree.

DECORATIVE TRIMMING

Decorative trimming is accomplished by removing all vegetation around trees, posts, fences, etc.. Rotate the whole unit so that the cutting head is at a 30° angle to the ground (Fig. 11).

AIR FILTER MAINTENANCE

WARNING:

clean or service it.

Cleaning the Air Filter

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

IDLE SPEED ADJUSTMENT

The idle speed of the engine is adjustable. An idle adjustment screw is between the air filter cover and the engine starter housing (Fig. 17).

NOTE: Careless adjustments can seriously damage the unit. An authorized service dealer should make

carburetor adjustments.

If, after checking the fuel mixture and cleaning the air filter, the engine still will not idle, adjust the idle speed screw as follows:

Idle Speed Screw

1. Start the engine and run for one minute

to warm up. Refer to Starting and

Stopping Instructions.

2. Release the throttle trigger and let the

engine idle. If the engine stops, insert a small Phillips screwdriver into the idle adjustment screw (Fig. 17). Turn the idle speed screw clockwise 1/8 of a turn at a time (as needed) until the engine idles smoothly.

3. If the engine appears to be idling too

fast, turn the idle speed screw

counterclockwise 1/8 of a turn at a

Fig. 17

time (as needed), to reduce idle speed.

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

• the engine will not idle

• the engine hesitates or stalls on acceleration

he cutting attachment will spin during idle speed adjustments. Wear protective clothing

WARNING:

and observe all safety instructions to prevent serious personal injury.
