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.

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 2cycle 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.

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 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 spilt fuel. Do not start the engine until fuel vapors dissipate.

CAUTION: For proper engine operation and

maximum reliability, pay strict attention to the oil and fuel mixing instructions on the 2-cycle oil container. Using improperly mixed fuel can severely damage the engine.

WARNING: Avoid accidental starting. Make sure

you are in the starting position when pulling the starter rope (Fig. 11). To avoid serious injury, the operator and unit must be in a stable position while starting.

WARNING:

Operate this unit only in a wellventilated outdoor area. Carbon monoxide exhaust fumes can be lethal in a confined area.

STARTING / STOPPING INSTRUCTIONS

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 attachment parallel to the ground.

• Do not force the cutting attachment. 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 trimmer 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 your cutting line is dependent upon:

• Following the trimming techniques

• What vegetation is being cut

• Where vegetation is cut

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

HOLDING THE TRIMMER

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

12). Check for the following:

• The operator is wearing eye protection and proper clothing

• With a slightly-bent right arm, the operator’s hand is holding the shaft grip

• The operator’s left arm is straight, the left hand holding the D-handle

• The unit is at waist level

•

The cutting attachment is parallel to the ground and easily contacts the grass without the need to bend ove

ADJUSTING TRIMMING LINE LENGTH

The Bump Head™ cutting attachment allows you to release trimming line without stopping the engine. To release more line, lightly tap the cutting attachment on the ground (Fig. 13) while operating the trimmer 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 attachment 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 you attempt a line release in tall grass, the engine may stall. Always keep the trimming line fully extended. Line release becomes more difficult when the cutting line gets shorter.

Fig. 13

Fig. 12

DECORATIVE TRIMMING

Decorative trimming is accomplished by removing all vegetation around trees, posts, fences and more.

Rotate the whole unit so that the cutting attachment is at a 30° angle to the ground (Fig. 14).

Fig. 14

OPERATING INSTRUCTIONS

CAUTION: Do not remove or alter the line cutting

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

WARNING: Always wear eye, hearing, foot and

body protection to reduce the risk of injury when operating this unit.

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. If you are unsure about these procedures take your unit to any non-road engine repair establishment, individual or authorized service dealer.

NOTE: Maintenance, replacement, or repair of the emission

control devices and system may be performed by any non-road engine repair establishment, individual or authorized service dealer.

In order to assure peak performance of your engine, inspection of the engine exhaust port may be necessary after 50 hours of operation. If you notice lost RPM, poor performance or general lack of acceleration, this service may be required. If you feel your engine is in need of this inspection, refer service to any non-road engine repair establishment, individual or authorized service dealer for repair. DO NOT attempt to perform this process yourself as engine damage may result from contaminants involved in the cleaning process for the port.

2. Clean around the spark plug. Remove the spark plug from

the cylinder head by turning a 5/8-inch socket counterclockwise.

3. Replace a cracked, fouled or dirty spark plug. Set the air gap at

0.025 in. (0.635 mm) using a feeler gauge (Fig. 31).

4. Install a correctly-gapped spark plug in the cylinder head.

Tighten by turning the 5/8-inch socket clockwise until snug.

If using a torque wrench torque to 110-120 in.•lb. (12.3-13.5

N•m). Do not over tighten.

CLEANING

Use a small brush to clean off the outside of the unit. Do not use strong detergents. Household cleaners that contain aromatic oils such as pine and lemon, and solvents such as kerosene, can damage plastic housing or handle. Wipe off any moisture with a soft cloth.

STORAGE

• Never store a fueled unit where fumes may reach an open flame or spark.

• Allow the engine to cool before storing.

• Store the unit locked up to prevent unauthorized use or damage.

• Store the unit in a dry, well-ventilated area.

• Store the unit out of the reach of children.

LONG TERM STORAGE

If you plan on storing the unit for an extended time, use the following storage procedure:

1. Drain all fuel from the fuel tank into a container with the

same 2-cycle fuel mixture. Do not use fuel that has been stored for more than 60 days. Dispose of the old fuel/oil mix in accordance to Federal, State and Local regulations.

2. Start the engine and allow it to run until it stalls. This ensures that

all fuel has been drained from the carburetor.

3. Allow the engine to cool. Remove the spark plug and put 1

oz. (30 ml) of any high quality motor oil or 2-cycle oil into the cylinder. Pull the starter rope slowly to distribute the oil. Reinstall the spark plug.

NOTE: Remove the spark plug and drain all of the oil from the

cylinder before attempting to start the trimmer after storage.

4. Thoroughly clean the unit and inspect it for any loose or

damaged parts. Repair or replace damaged parts and tighten loose screws, nuts or bolts. The unit is ready for storage.

TRANSPORTING

• Allow the engine to cool before transporting.

• Drain fuel from unit.

• Tighten fuel cap before transporting.

• Secure the unit while transporting.

2. Release the throttle trigger and let the engine idle. If the engine stops, insert a small phillips or flat blade screwdriver into the hole in the air filter/muffler cover (Fig.

30). Turn the idle speed screw in, clockwise, 1/8 of a turn at a time (as needed) until the engine idles smoothly.

NOTE: The cutting attachment should not rotate when the

engine idles.

3. If the cutting attachment rotates when the engine idles, turn the idle speed screw counterclockwise 1/8 of a turn at a 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

• there is a loss of engine power

Have the carburetor adjusted by an authorized service dealer.

REPLACING THE SPARK PLUG

Use a Champion RDJ7Y spark plug, or equivalent. The correct air gap is 0.025 inch (0.635 mm). Remove the plug after every 25 hours of operation and check its condition.

1. Stop the engine and allow it to cool. Grasp the plug wire firmly and pull the boot from the spark plug.

0.025 in.

Check Fuel Mixture

Old and/or improperly mixed fuel is usually the reason for improper unit performance. Drain and refill the tank with fresh, properly-mixed fuel prior to making any adjustments. Refer to Oil and Fuel Information.

Clean Air Filter

The condition of the air filter is important to the operation of the unit. A dirty air filter will restrict air flow and change the air/fuel mixture. This is often mistaken for an out of adjustment carburetor. Check the condition of the air filter before adjusting the idle speed screw. Refer to Air Filter Maintenance.

Adjust Idle Speed Screw

If, after checking the fuel mixture and cleaning the air filter, 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.

CARBURETOR ADJUSTMENT

The idle speed of the engine is adjustable through the air filter/muffler cover (Fig. 30).

NOTE: Careless adjustments can seriously damage your unit.

An authorized service dealer should make carburetor adjustments.

MAINTENANCE AND REPAIR INSTRUCTIONS

WARNING: The cutting attachment may spin

during idle speed adjustments. Wear protective clothing and observe all safety instructions to prevent serious personal injury.

WARNING: To prevent serious personal injury,

make sure the cutting attachment has stopped rotating before you turn it off and set it down.

WARNING: Do not sand blast, scrape or clean

electrodes. Grit in the engine could damage the cylinder.

WARNING: To avoid serious personal injury,

always turn your trimmer off and allow it to cool before you clean or maintain it.

If further assistance is required, contact your authorized service dealer.
