OIL AND FUEL INFORMATION

RECOMMENDED FUEL TYPE

Old fuel is the primary reason for improper unit performance. Be sure to use fresh, clean, unleaded gasoline.

NOTE: This is a four cycle engine. In order to avoid damage to the unit, do not mix oil with gasoline.

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 or form acids when stored. Use fresh fuel (less than 60 days old), when using alcohol-blended fuel.

Using Blended Fuels

If you choose to use a blended fuel, or its use is unavoidable, follow recommended precautions:

Always use fresh unleaded gasoline
- Use the fuel additive STA-BIL® or an equivalent
- Drain tank and run the engine dry before storing unit

Using Fuel Additives

The use of fuel additives, such as STA-BIL® Gas Stabilizer or an equivalent, will inhibit corrosion and minimize the formation of gum deposits. Using a fuel additive can keep fuel from forming harmful deposits in the carburetor for up to six (6) months. 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 gas tank.

FUELING THE UNIT

WARNING: Gasoline is extremely flammable and its vapors can explode if ignited. To avoid serious personal injury, 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.

1. Remove the fuel cap (Fig. 9).

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

Fig. 9

1. Place the gas container's spout into the fill hole on the fuel tank (Fig. 9) and fill the tank.

WARNING: Add gasoline in a clean, well-ventilated outdoor area. Avoid creating a source of ignition for spilt fuel.

NOTE: Do not overfill the tank.

1. Wipe up any gasoline that may have spilled.
2. Reinstall the fuel cap.

WARNING: Never operate the unit without the fuel cap securely in place.

1. Move the unit at least 30 ft. (9.1 m) from the fueling source and site before starting the engine.

NOTE: Dispose of the old gasoline in accordance to Federal, State and Local regulations.

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. 17). 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 J-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. 17

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. 18) 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.

Fig. 18

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. 19).

MAINTENANCE AND REPAIR INSTRUCTIONS

AIR FILTER MAINTENANCE

Cleaning the Air Filter

Clean and re-oil the air filter every 10 hours of operation. It is an important item to maintain. Failure to maintain the air filter will Void the warranty.

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

1. Open the air filter cover. Push the tab on the right side of the cover inward. Then pull the air filter cover out and to the left (Fig. 35).
   NOTE: It may be necessary to remove the fuel cap to completely remove the air filter cover.
2. Remove the air filter (Fig. 35).

Fig. 35

1. Wash the filter in detergent and water (Fig. 36). Rinse the filter thoroughly and allow it to dry.

Fig. 36

1. Apply enough clean SAE 30 motor oil to lightly coat the filter (Fig. 37).

Fig. 37
Fig. 38

1. Squeeze the filter to spread and remove excess oil (Fig. 38).
2. Replace the filter (Fig. 39).

NOTE: If the unit is operated without the air filter, you will Void the warranty.

Fig. 39

1. Reinstall the air filter cover. Position the hooks on the left side of the air filter cover into the slots at the left side of the back plate (Fig. 39).
   NOTE: It may be necessary to remove the fuel cap to reinstall the air filter cover.
2. Swing the cover to the right until the tab on the air filter cover snaps into place in the slot on the back plate (Fig. 39).
3. Replace the fuel cap if it was removed.

CARBURETOR ADJUSTMENT

The idle speed of the engine is adjustable. An idle adjustment screw is reached though a hole in the top of the engine cover (Fig. 40).

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

Check Fuel

Old fuel is usually the reason for improper unit performance. Drain and refill the tank with fresh fuel prior to making any adjustments. Refer to Oil and Fuel Information.

MAINTENANCE AND REPAIR INSTRUCTIONS

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

If, after checking the fuel 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.
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. 40). 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.

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, 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: To prevent serious personal injury, make sure the cutting attachment has stopped rotating before you turn it off and set it down.

Fig. 40

This requires disassembly of the engine. If you feel unsure or unqualified to perform this, take the unit to an authorized service center.

NOTE: Inspect the valve to rocker arm clearance with a feeler gauge after the first 10 hours of operation and then every 25 hours of operation thereafter.

• The engine must be cold when checking or adjusting the valve clearance.

• This task should be performed inside, in a clean, dust free area.

• Remove the muffler cover by pressing down on it, separating it from the engine cover. Using a flat blade screwdriver, disengage the middle and front tabs and slots first. The cover will hinge off from the rear tab (Fig. 41).

Fig. 41

1. Remove the two (2) screws on top of the engine cover with a Flat-head or T-20 Torx screwdriver (Fig. 42).

Fig. 42

MAINTENANCE AND REPAIR INSTRUCTIONS

1. Remove the screw behind the engine cover (Fig. 43).

Fig. 43

1. Disconnect the spark plug wire.
2. Clean dirt from around the spark plug. Remove the spark plug from the cylinder head by turning a 5/8 in. socket counterclockwise.
3. Remove the engine cover (Fig. 42).
4. Clean dirt from around the rocker arm cover. Remove the screw holding the rocker arm cover with a large flat blade screwdriver or Torx T-25 bit (Fig. 44). Remove the rocker arm cover and gasket.

Fig. 44

1. Pull the starter rope slowly to bring the piston to the top of its travel, (known as top dead center). Check that:

2. The piston is at the top of its travel while looking in the spark plug hole (Fig. 44)

3. Both rocker arms move freely, and both valves are closed

If these statements are not true, repeat this step.

1. Slide the feeler gauge between the rocker arm and the valve return spring. Measure the clearance between the valve stem and rocker arm (Fig. 45). Measure both the intake and exhaust valves.

The recommended clearance for the intake is .003 - .006 in. (.076 - 0.152 mm). The recommended clearance for the exhaust is .013 - .016 in. (.330 - 0.406 mm).

Use a standard automotive .005 in. (0.127 mm) feeler gauge. The feeler gauge should slide between the rocker arm and valve stem with a slight amount of resistance, without binding. Figure 45 shows how to measure the intake clearance, while Figure 46 shows the exhaust clearance.

Fig. 45

Fig. 46

1. If the clearance is not within specification:

a. Turn the adjusting nut using a 5/16 inch (8 mm) wrench or nut driver (Fig. 46).

• To increase clearance, turn the adjusting nut counterclockwise.
• To decrease clearance, turn the adjusting nut clockwise.

b. Recheck both clearances, and adjust as necessary.

1. Reinstall the rocker arm cover using a new gasket. Torque the screw to 20-30 in·lb (2.2-3.4 N·m).

2. Reinstall the engine cover. Check alignment of the cover before tightening the screws. Tighten screws.

3. Reinstall the muffler cover. Slip the rear tab on the muffler cover into the engine cover rear slot. Then slide the remaining slots into the tabs until they snap into place (Fig. 41).

4. Check the spark plug and reinstall. See Replacing the Spark Plug.

5. Replace the spark plug wire.

MAINTENANCE AND REPAIR INSTRUCTIONS

REPLACING THE SPARK PLUG

Use only Champion RDZ19H spark plug or equivalent. The correct air gap is 0.025 in. (0.655 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 cap from the spark plug.
2. Clean dirt from around the spark plug. Remove the spark plug from the cylinder head by turning a 5/8 in. socket counterclockwise.
3. Replace cracked, fouled or dirty spark plug. Set the air gap at 0.025 in. (0.655 mm.) using a feeler gauge (Fig. 47).

Fig. 47

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. Turn the 5/8 in. 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.

SPARK ARRESTOR MAINTENANCE

1. Remove the muffler cover. See Rocker Arm Clearance.
2. With a flat blade screwdriver or Torx T-20 bit, remove the screw attaching the spark arrester cover to the muffler (Fig. 48).

Fig. 48

1. Pull the tab on the spark arrestor cover out of the muffler. Remove the spark arrestor cover.
2. Remove the spark arrestor screen from the spark arrestor cover.
3. Clean the spark arrestor screen with a wire brush or replace it.
