Oil and Fuel Information

NOTE: Alcohol-blended fuel absorbs moisture (water). As little as 1% moisture in the fuel can cause fuel and oil to separate and form acids when stored. If alcohol-blended fuel must be used, use fresh fuel (less than 60 days old), and mix according to the mixing instructions.

Definition of Blended Fuels

Today's fuels are often a blend of gasoline and one or more oxygenates such as ethanol, methanol or MTBE (ether).

Use of Blended Fuels

If you choose to use a blended fuel or its use is unavoidable, the following precautions are recommended.

• Always use fresh fuel mix per your operator's manual.
• Use the special 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.

Use of Fuel Additives

The use of fuel additive, such as STA-BIL® Gas Stabilizer or an equivalent, will inhibit corrosion and minimize the formation of gum deposits. Add 0.8 oz (23 ml) per gallon of fuel per instructions on container. NEVER add fuel additives directly to the unit's fuel tank. Using a fuel additive can keep fuel fresh for up to six (6) months.

WARNING: Gasoline is extremely flammable and its vapors can explode if they are ignited. 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 away from the area.

WARNING: Remove fuel cap slowly to avoid injury from fuel spray.

CAUTION: For proper engine operation and maximum reliability, pay strict attention to the oil and fuel mixing instructions on the 2-cycle oil container. Use a 32:1 fuel/oil ratio. Use 2-cycle oil. Using improperly mixed fuel can severely damage the engine.

Oil and Fuel Mixing Instructions

Thoroughly mix the proper ratio of unleaded gasoline with 2-cycle engine oil in a separate fuel can, 32:1. Do not mix them directly in the engine fuel tank. See the table below for specific gas and oil mixing ratios.

Operating Instructions

Adjusting Trimming Line Length

Your trimmer is equipped with a bump head that allows the operator to release more trimming line without stopping the engine. To release additional line, lightly tap the trimming head on the ground (Fig. 10) while operating the trimmer at high speed.

NOTE: Always keep the trimming line fully extended. Line release becomes more difficult as cutting line becomes shorter.

For best results, tap the head on bare ground or hard soil. If line release is attempted in tall grass, the engine may stall.

CAUTION: Do not remove or alter the line cutting blade assembly. Excessive line length will cause clutch to overheat and may result in serious personal injury.

Diagram description for Fig. 10: Shows tapping the trimmer head on the ground to release line.

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

Decorative Trimming

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

Rotate the entire unit so that the string head is at a 30° angle to the ground (Fig. 11).

Diagram description for Fig. 11: Shows the trimmer at a 30-degree angle for decorative trimming.

Maintenance and Repair Instructions

Maintenance Schedule

These required maintenance procedures should be performed at the frequency stated in the table. They should also be included as part of any seasonal tune-up.

WARNING: Never perform maintenance or repairs with unit running. Always perform maintenance and repairs on a cool unit. Disconnect spark plug wire to make sure the unit will not start.

Line Installation

The trimming line may be replaced by two different methods - rewinding the existing reel or installing a prewound reel.

Rewinding the Existing Reel

To rewind the existing reel you must:

• Check for the correct line size.
• Remove the existing reel and spring.
• Wind the existing reel with the new line.
• Reinstall the existing reel and spring.

The Correct Line to Use

NOTE: It is very important to use the correct size line. A line with a diameter of 0.080 inch (2.03 mm) must be used. The engine may overheat and fail if you use a larger line.

Removing the Existing Reel

1. Hold the outer spool with one hand and unscrew the Bump Knob™ counterclockwise (Fig. 12). Inspect the captured bolt inside the Bump Knob to make sure it moves freely. Replace the Bump Knob if it is damaged.

2. Remove the inner reel (Fig. 13).

3. Use a clean cloth to clean the inner surface of the outer spool (Fig. 14).

NOTE: Always clean the inner reel, outer spool, and shaft before reassembling the bump head.

Diagram description for Fig. 13: Shows removing the inner reel.

Diagram description for Fig. 14: Shows cleaning the outer spool.

4. Check the indexing teeth on the inner reel and outer spool for wear (Fig. 15). If necessary, remove burrs or replace the reel and spool.

Diagram description for Fig. 15: Shows checking indexing teeth on the reel and spool.

Winding the Existing Reel

1. Take approximately 25 feet (7.6 m) of new trimming line, loop it into two equal lengths. Insert each end of the line through one of the two holes in the inner reel (Fig. 16). Pull the line so that the loop is as small as possible.

2. Place your index finger between the two lines to stop the lines from overlapping (Fig. 17).

3. Wind the lines, in even and tight layers, onto the reel (Fig. 17). Wind the line in the direction indicated on the inner reel. Be sure not to overlap the two ends of the line.

NOTE: Failure to wind the line in the direction indicated will cause the string head to operate incorrectly.

3. Insert the ends of the line into the two holding slots (Fig. 18).

Diagram description for Fig. 23: Shows applying oil to the air filter.

Diagram description for Fig. 24: Shows squeezing excess oil from the air filter.

Carburetor Adjustment

This unit is equipped with a diaphragm-type carburetor that has been carefully calibrated at the factory. In most cases, no further adjustment is required.

NOTE: To meet the 1995-1998 California emission regulations, the carburetor has adjustment needle limiter caps to restrict the amount of adjustment. Removal or alteration of these caps will void the unit's warranty.

Old or improperly mixed fuel are usually the main reasons for the unit not running properly. Drain and refill the tank with fresh properly mixed fuel prior to making any adjustments. Refer to Oil and Fuel Information.

The condition of the air filter is important to the operation of the unit. A dirty air filter will restrict the air flow, which upsets the fuel-air mixture in the carburetor. The resulting symptoms are often mistaken for an out-of-adjustment carburetor. Therefore, check the condition of the air filter before adjusting the carburetor. Refer to Air Filter Maintenance.

Adjusting Carburetor

1. Clean the air filter if it is dirty. Refer to Air Filter Maintenance.

2. Make the initial settings with the engine stopped. These initial settings should allow you to start and warm up the unit before making the final adjustments.

Initial Idle Speed Setting

a. For Walbro carburetors: Back the idle speed screw (Fig. 25) out, counterclockwise, until it does not contact the carburetor throttle lever. Then turn the screw in, clockwise, until it just begins to move the throttle lever; then continue turning 2 full turns.

b. For Zama carburetors: Back the idle speed screw (Fig. 26) out, counterclockwise, until it does not contact the throttle lever. Then turn the screw in, clockwise, until it just begins to move the throttle lever, then continue turning 1-1/2 turns.

3. Initial High Speed Mixture and Idle Speed Mixture Needle Settings: Turn both the high speed mixture and idle speed mixture needles out, counterclockwise, until the limiter caps stop.

4. Start the engine and let it run for a minute.

5. Release the throttle trigger and let the engine idle. If the engine stops, turn the idle speed screw (Figs. 25 and 26) in, clockwise, 1/8 turn at a time (as required) until the engine idles.

NOTE: Forcing the limiter caps with a screwdriver will damage the needle tips and the seat in the carburetor body.

Final Idle Speed Screw and Idle Speed Mixture Needle Settings

Adjust the idle speed screw and idle speed mixture needle for smoothest engine idle.

a. Turn the idle speed mixture needle (Figs. 25 and 26) in, clockwise, until you hear the fastest idle; then turn the needle out, counterclockwise, 1/8 turn.

b. Squeeze the throttle trigger. If the engine falters or hesitates as it accelerates, turn the idle speed mixture needle out, counterclockwise, 1/16 turn at a time until the engine accelerates rapidly.

c. If the idle speed changes significantly because of Steps a and b, readjust the idle speed screw (refer to Step 2).

NOTE: The bump head/line spool should not rotate when the engine idles.

Final High Speed Mixture Needle Adjustment

1. High speed mixture needle adjustment is not recommended without a precision high speed tachometer.

2. The factory presets the high speed mixture needle at 1-1/4 turns out from the closed position. Your unit should perform well at this setting. If additional adjustment of the high speed mixture needle is required, contact your local authorized service dealer.

Diagram description for Fig. 25: Shows a Walbro Carburetor with Idle Speed Mixture Needle, Idle Speed Screw, and High Speed Mixture Needle.

Diagram description for Fig. 26: Shows a Zama Carburetor with Idle Speed Mixture Needle, Idle Speed Screw, and High Speed Mixture Needle.

Replacing the Spark Plug

Use a Champion RDJ7Y spark plug (or equivalent). Correct air gap is 0.020 in (0.5 mm). Remove plug after every 50 hours of operation and check its condition.

1. Stop the engine and allow it to cool. Pull the wire off of the spark plug.

2. Clean around the spark plug and remove it from the cylinder head. Use a 5/8" socket to remove the plug.

CAUTION: Replace a cracked, fouled or dirty spark plug. Do not sand blast, scrape, or clean electrodes because the engine could be damaged by grit entering the cylinder.

3. Set the air gap at 0.020 in (0.5 mm) using a wire feeler gauge (Fig. 27). Install a correctly gapped spark plug into the cylinder head. Torque to 110-120 in•lb (12.3-13.5 N•m).

Diagram description for Fig. 27: Shows setting the spark plug gap to 0.020 in (0.5 mm).

Inspecting the Muffler

The muffler should be removed every 25 hours of operation to inspect for excessive carbon build-up. Excessive deposits around the exhaust port (Fig. 28) or exhaust holes will cause poor engine performance.

Use the following procedure to remove, inspect, and reinstall the muffler.

WARNING: To avoid serious personal injury, make sure that the muffler is cool before removing and inspecting.

Removing Muffler

1. Remove the muffler mounting bolts (Fig. 28).

2. Remove the muffler (with heat shield) and gasket. Discard the old gasket.

Diagram description for Fig. 28: Shows muffler mounting bolts and exhaust port.

3. Check the inlet port of the muffler and outlet port of the cylinder for excessive carbon deposits (Figs. 29 and 30). Clean or replace the muffler as required. If the outlet port of the cylinder is plugged, contact your authorized service dealer.

4. Inspect the muffler mounting holes for elongation. Replace the muffler and muffler bolts if the holes are elongated.

Diagram description for Fig. 29: Shows the muffler inlet port.

Diagram description for Fig. 30: Shows the cylinder outlet port and muffler gasket.

Reinstalling Muffler

1. Install a new gasket. Make sure the arrow stamped into the gasket is to your right. Tuck the tab (with the arrow) between the cylinder and plastic shroud (Fig. 30).

2. Install the muffler with the muffler mounting bolts (Fig. 28) and torque the bolts to 80-90 in•lb (9-10.1 N•m).

Cleaning

WARNING: To avoid serious personal injury, always turn your trimmer off and allow it to cool before you clean or perform any maintenance on it.

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

Storage

If the unit will be stored for an extended period of time, use the following storage procedure.

1. Drain all fuel from the fuel tank and drain 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 a safe manner and use a fresh mix.
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 approximately 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.
4. NOTE: Remove the spark plug and drain all of the oil from the cylinder before attempting to start the trimmer after storage.
