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

• WARNING: It has been proven that fuel containing greater than 15% ethanol will likely damage this engine and void the warranty.
• Today’s fuels are often a blend of gasoline and oxygenate 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

OIL AND FUEL INFORMATION

USING FUEL ADDITIVES

• 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.
• The bottle of 2-cycle oil contains a fuel additive that 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 under Federal, State, and Local regulations.

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.

1. Remove the fuel cap.
   • WARNING: Remove the fuel cap slowly to avoid injury from the fuel spray.
   • Never operate the unit without the fuel cap securely in place.
   • WARNING: 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.
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.

OPERATING INSTRUCTIONS

HOLDING THE UNIT

WARNING: Always wear eye, hearing, foot, and body protection to reduce the risk of injury when operating this unit.

Before operating the unit, stand in the operating position (Fig. 9).

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 head is parallel to the ground and easily contacts the grass without the need to bend over

ADJUSTING TRIMMING LINE LENGTH

• WARNING: Do not remove or alter the line-cutting blade assembly. Excessive line length will cause premature engine failure and/or unit damage.
• The Bump Head™ cutting head allows the release of the trimming line without stopping the engine. To release more lines, 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 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 the 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
• 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).

MAINTENANCE AND REPAIR INSTRUCTIONS

MAINTENANCE SCHEDULE

• WARNING: To prevent serious injury, never perform maintenance or repairs with the unit running.
• Always service and repair a cool unit. Disconnect the spark plug wire to ensure that the unit cannot start.
• 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.

WARNING: Never use metal-reinforced line, wire, chain, or rope.
These can break off and become dangerous projectiles.

1. Rotate the bump knob clockwise until all line is inside the cutting head (Fig. 12).
2. Using a flat-head screwdriver, insert the tip into the line dimple and just under the exposed portion of the line (Fig. 13)
3. Pull the line straight out until all line is removed from the cutting head.

LINE INSTALLATION

Always use the original equipment manufacturer 0.095 in. (2.41 mm) replacement line.

1. Align the arrows on the bump knob with the spool cover eyelets, if they are not already (Fig. 14).
2. Using 16 ft. (3.2 m) of 0.095 in. (2.41 mm) replacement line push both ends of the line through the holes in the bump knob until they protrude through the eyelets on both sides of the cutting head.
   • Continue pulling the line until approximately 6 ft. (1.5 m) is visible from both sides of the cutting head. (Fig. 15)
3. Hold the spool cover, turn the bump knob clockwise to wind the line around the spool until about 5 in. (12.7 cm) is protruding from each side of the cutting head. (Fig. 12)
4. Start the unit and bump the cutting head on the ground until the desired cutting length is achieved. The excess line will be trimmed off by the line blade.
   • NOTE: If the cutting line ends are pulled into the cutting head or the line becomes twisted, refer to Removing the Line.

AIR FILTER MAINTENANCE

WARNING: To avoid serious personal injury, always turn the unit off and allow it to cool before you clean or service it.

Cleaning the Air Filter

Clean and re-oil the air filter every 25 hours of operation. 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 top of the cover inward, then pull the air filter cover out and down. (Fig. 16).
2. Remove the air filter (Fig. 16).
3. Wash the filter with detergent and water (Fig. 17).
   • Rinse the filter thoroughly and allow it to dry.
4. Apply enough clean SAE 30 motor oil to lightly coat the filter (Fig. 18).
5. Squeeze the filter to spread and remove excess oil (Fig. 19).
6. Replace the filter (Fig. 18).
   • NOTE: If the unit is operated without the air filter, you will VOID the warranty.
7. Reinstall the air filter cover. Position the slots on the bottom of the air filter cover onto the tabs at the bottom of the back plate (Figs. 18).
8. Swing the cover-up until the tab on the air filter backplate snaps into place in the slot on the air filter cover (Fig. 18).

CARBURETOR 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. 20).
• NOTE: Careless adjustments can seriously damage the unit. An authorized service dealer should make carburetor adjustments.

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 before 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 airflow 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

• WARNING: The cutting attachment will spin during idle speed adjustments.
• Wear protective clothing and observe all safety instructions to prevent serious personal injury.

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 run for one minute to warm up. Refer to Starting/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. 20).
   • 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 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 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 replacement #753-06193, a Champion RDJ8J 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 it from the spark plug.
2. Clean around the spark plug. Remove the spark plug from the cylinder head by turning a 5/8-inch socket counterclockwise.
   • WARNING: Do not sandblast, scrape, or clean electrodes. Grit in the engine could damage the cylinder.
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. 22).
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

WARNING: To avoid serious personal injury, always turn the unit off and allow it to cool before you clean or service it.

• 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 planning 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 under 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 unit 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.
