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 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.

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.

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.

MIXING RATIO - 40:1

+ UNLEADED GAS	2 CYCLE OIL
1 GALLON US (3.8 LITERS)	3.2 FL. OZ. (95 ml)
1 LITER	25 ml

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.

NOTE: Dispose of the old fuel/oil mix in accordance to Federal, State and Local regulations.

STARTING/STOPPING INSTRUCTIONS

WARNING: Operate this unit only in a well-ventilated outdoor area. Carbon monoxide exhaust fumes can be lethal in a confined area.

WARNING: Avoid accidental starting. Make sure you are in the starting position when pulling the starter rope (Fig. 8). To avoid serious injury, the operator and unit must be in a stable position while starting.

Make sure that any Add-On item is installed correctly and secure before starting the unit.

Fig. 6

STARTING INSTRUCTIONS

1. Mix gas with oil. Fill fuel tank with fuel/oil mixture. See Oil and Fuel Mixing Instructions.
   NOTE: There is no need to turn the unit on. The On/Off Stop Control is in the ON (1) position at all times.
2. Fully press and release the primer bulb 10 times, slowly. Some amount of fuel should be visible in the primer bulb and fuel lines (Fig. 7). If you can't see fuel in the bulb, press and release the bulb as many times as it takes before you can see fuel in it.
3. Push the EZ-Start™ Lever towards the primer bulb until it clicks and locks into place (Fig. 7).
4. Crouch in the starting position and do not squeeze the throttle control (Fig. 8). Pull the starter rope out with a controlled and steady motion until the engine attempts to start. Repeat until the engine starts.
   NOTE: The unit uses Advanced Starting Technology™, which significantly reduces the effort required to start the engine. You must pull the starter rope out far enough to hear the engine attempt to start. There is no need to pull the rope briskly-- there is no harsh resistance when pulling. Be aware that this starting method is vastly different from (and much easier than) what you may be used to.
5. When the engine starts, squeeze the throttle control for 15 to 30 seconds. This will warm up the unit. The EZ-Start™ Lever will click off automatically when you squeeze the throttle control.
   IF... The engine does not start, go back to step 2.
   IF... The engine stops while you are squeezing the throttle, go back to step 3.
   IF... The engine stops before you squeeze the throttle control, hold the throttle control and pull the starter rope until the trimmer starts.
   NOTE: If you are having trouble starting the unit or are operating in extreme temperatures (below 40^ F, above 90^ F), refer to the Troubleshooting section.

STOPPING INSTRUCTIONS

1. Release your hand from the throttle control. Allow the engine to cool down by idling.
2. Put the On/Off Stop Control in the OFF (O) position (Fig. 6).

Fig. 7

Fig. 8

Fig. 11

CAUTION: The cutting attachment and add-ons with the EZ-Link™ system are to be used in the primary hole unless stated otherwise in the specific add-ons operator's manual. Using the wrong hole could lead to personal injury, or damage to the unit.

For edging (when using the line head cutting attachment with EZ-Link™ models), lock the release button of the cutting attachment into the 90^ edging hole or the 180^ edging hole (Fig. 11).

OPERATING INSTRUCTIONS

HOLDING THE TRIMMER

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. 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 over

Fig. 12

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.

13

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.

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

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.

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.

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

2. Locate the muffler front and the two (2) bolts securing it to the engine (Fig. 31). Remove the two (2) bolts using a flatblade screwdriver or 5/16-inch socket or nut driver. Pull the muffler off of the engine.
3. Turn the muffler over to the back side and locate the exhaust gasket. Remove the muffler gasket from the muffler (Fig. 31).

NOTE: If exhaust gasket is torn or damaged, replace with a new gasket before reassembling muffler.

1. Using a small flatblade screwdriver, carefully pry up the spark arrestor from the recessed hole (Fig. 32). Remove the spark arrestor from muffler.
2. Clean the spark arrester with a wire brush. Replace it if it is damaged or if it is impossible to clean thoroughly (Fig. 32).
3. Reinstall the spark arrester by pressing it into the recessed hole on the muffler's back side. Make sure it fits tightly against the muffler and is not raised up.
4. Place the exhaust gasket against the muffler's back side. Align the exhaust gasket bolt holes with the bolt holes in the muffler. While holding the exhaust gasket in place, insert bolts into muffler's front side (Fig. 31).
5. Place the muffler (with the exhaust gasket in place and the bolts inserted) against the engine, aligning the bolt holes. Tighten the bolts to secure the muffler to the engine.

If using a torque wrench torque to: 80-90 in. • lb. (9-10.2 N • m).

WARNING: If muffler is not tightened securely, it could fall off causing damage to the unit and possible serious personal injury.

1. Reinstall air filter/muffler cover.

MAINTENANCE AND REPAIR INSTRUCTIONS

CARBURETOR ADJUSTMENT

The idle speed of the engine is adjustable through the air filter/muffler cover (Fig. 33).

NOTE: Careless adjustments can seriously damage your 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 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.

WARNING: The cutting attachment may be spinning during idle speed adjustments. Wear protective clothing and observe all safety instructions to prevent serious personal injury.

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

Fig. 33

NOTE: The cutting attachment should not rotate when the engine idles.

1. 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.

WARNING: When the unit is turned off, make sure the cutting attachment has stopped before the unit is set down. This will help to prevent serious personal injury.

MAINTENANCE AND REPAIR INSTRUCTIONS

REPLACING THE SPARK PLUG

Use a Champion RDJ7Y spark plug (or equivalent). The correct air gap is 0.020 inch (0.5 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 in. socket counterclockwise.
3. Replace a cracked, fouled or dirty spark plug. Set the air gap at 0.020 in. (0.5 mm) using a feeler gauge (Fig. 34).

CAUTION: Do not sand blast, scrape, or clean electrodes. Grit in the engine could damage the cylinder.

1. 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.

Fig. 34

CLEANING

WARNING: To avoid serious personal injury, always turn your trimmer off and allow it to cool before you clean or do any maintenance on 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 the unit with fuel in the tank 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 the unit will be stored 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.
