OIL & FUEL INFORMATION

RECOMMENDED OIL TYPE

It is extremely important to use the proper type and weight of oil in the crankcase. Check the oil before each use and change the oil regularly. The use of incorrect or dirty oil can cause premature engine wear and failure.

Use a high-quality SAE 30 weight oil of API (American

Petroleum Institute) service class SF, SG, SH.

ADDING OIL TO CRANKCASE: INITIAL USE

NOTE: This unit is shipped without oil. To avoid damaging the unit, put oil in the crankcase before attempting to start it.

NOTE: This 4-Cycle trimmer is shipped for operation in conditions above 40°F (4°C).

For cold weather operation, where temperatures dip below 40°F (4°C), use a high-quality SAE 10W30 weight oil of API

(American Petroleum Institute) service class

SF, SG, SH.

1. Place the unit on a flat level surface. See

Figure 3. It is crucial to keep the unit level when filling with oil.

2. Remove the oil plug/dipstick from the crankcase.

3. Pour 100ml of oil into the oil fill hole. See Figure 4.

NOTE: Never add oil to the fuel or fuel tank.

4. Wipe up any oil that may have spilled and reinstall the oil fill plug/dipstick.

The importance of checking and maintaining the proper oil level in the crankcase cannot be overemphasized. Check oil before each use and change as specified in the Maintenance Schedule.

FIGURE 3

FIGURE 4

RECOMMENDED FUEL TYPE

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

NOTE: This is a four cycle engine. In order to avoid

damage to the unit, do not mix oil with petrol (gasoline) .

OIL & FUEL INFORMATION

DEFINITION OF BLENDED FUELS

Today's fuels are often a blend of petrol 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 form acids when stored. When using alcohol-blended fuel, use fresh fuel that is less than 60 days old.

Using Blended Fuels

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

• Always use fresh unleaded petrol (gasoline)

• Use the fuel additive STA-BIL® or an equivalent

• Drain tank and run the engine dry before storing the 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 UNIT

WARNING: Petrol (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 and.

NOTE: Fill or add fuel to the tank only when the trimmer is in a horizontal position.

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

2. Place the spout of the gas container into the fill hole on the fuel tank and fill. See Figure 5.

FIGURE 5

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

NOTE: Do not overfill tank.

3. Wipe up any petrol that may have spilled.

4. Reinstall the fuel cap.

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

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

NOTE: Dispose of the old petrol 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. See Figure 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, and the hand is holding the D-Handle

• The unit is at waist level

• The cutting head is parallel to the ground and easily contacts the vegetation without the need to bend over

FIGURE 9

12

OPERATING INSTRUCTIONS

ADJUSTING TRIMMING LINE LENGTH

The Bump Head™ allows you to release trimming line without stopping the engine. To release more line, lightly tap the cutting head on the ground while operating the trimmer at high speed. See Figure 10.

FIGURE 10

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

Each time the head is bumped, it releases about 25.4

mm (1 inch) of trimming line. A blade in the string guard cuts the line to the proper length if excess line is released.

For best results, tap the Bump Head™ on bare ground or hard soil. If you attempt to release line in tall grass, the engine may overheat. Always keep the trimming line fully extended. Line release becomes more difficult as the cutting line becomes shorter.

NOTE: Do not rest the Bump Head™ on the ground while the unit is running.

CAUTION: Do not remove or alter the line cutting blade assembly. Excessive line length will make the unit overheat. This may lead to serious personal injury or damage to the unit.

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

DECORATIVE TRIMMING

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

30-degree angle when trimming with this method. See

Figure 11.

FIGURE 11

TIPS FOR BEST TRIMMING RESULTS

1. The correct angle for the cutting head is parallel to the ground.

NOTE: Do not rest the Bump Head™ on the ground.

2. DO NOT FORCE THE UNIT. Allow the very 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.

3. Grass over 200 mm (8 in.) should be cut by working from top to the bottom in small increments to avoid premature line wear or engine drag.

4. Whenever possible, cut right to left. When cutting to the left, the unit's cutting efficiency is improved slightly. Also, the clippings are thrown away from the operator.

5. Slowly move the trimmer into and out of the area being cut, keeping the trimmer at the desired cutting height. Move either in a forward-tobackward or side-to-side motion. Cutting shorter lengths produces best results.

6. Trim only when grass and weeds are dry.

7. 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.

MAINTENANCE & REPAIR INSTRUCTIONS

CHECKING THE OIL LEVEL

CAUTION: To prevent extensive engine wear and damage to the unit, always maintain the proper oil level in the crankcase. Never operate the unit with the oil level below the bottom of the dipstick.

The importance of checking and maintaining the proper oil level in the crankcase cannot be overemphasized. Check oil before each use:

1. Stop engine and allow oil to drain into the crankcase.

2. To get a proper oil level reading, place the unit on a flat, level surface.

3. Keep dirt, grass clippings and other debris out of the engine. Clean the area around the oil fill plug/dipstick before removing it.

4. Remove the oil fill plug/dipstick and wipe off oil.

Reinsert it all the way back in.

5. Remove the oil fill plug/dipstick and check the oil level. The oil should reach the top of the dipstick.

See Figure 24.

CHANGING THE OIL

For a new engine, change the oil after the first 10 hours of operation. Change the oil while the engine is still warm. The oil will flow freely and carry away more impurities.

CAUTION: Wear gloves to prevent injury when handling the unit.

1. Unplug spark plug boot to eliminate starting.

2. Remove the oil fill plug/dipstick.

3. Pour the oil out of the oil fill hole and into a container by tipping the unit to a vertical position.

MAINTENANCE & REPAIR INSTRUCTIONS

CARBURETOR SETTING

The idle speed of the engine is adjustable through the air filter/muffler cover. See Figure 26.

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

Check Fuel Mixture

Old or dirty 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.

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.

Adjusting the Idle Speed

WARNING: The cutting head may spin during idle speed adjustment. 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 as follows:

1. Start the engine and let it run at a high idle for a minute to warm up.

2. Release the throttle trigger and let the engine idle.

If the engine stops, engage the idle speed screw with a small screwdriver. See figure 26. 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 head should not rotate when the engine idles.

Idle Speed Screw

FIGURE 26

3. If the cutting head 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.

These procedures should solve most engine problems.

If this isn’t the case, and:

• 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: After the unit is turned off, make sure the cutting head has stopped before you set down the unit. This will help prevent serious personal injury.

ROCKER ARM CLEARANCE

This procedure 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.

3. Disconnect the spark plug wire.

4. Remove the spark plug.

5. Remove the engine cover.

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

Check that:

• While looking in the spark plug hole, the piston is at the top of its travel. See Figure 29.

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

If not, repeat this step.

8. Slide the feeler gauge between the rocker arm and the valve return spring. Measure the clearance between the valve stem and rocker arm. Measure both the intake and exhaust valves. See Figure 30.

The recommended clearance for both intake and exhaust is .076 – 0.152 mm (.003 – .006 in.). Use a standard automotive 0.127 mm (.005 in.) feeler gauge.

The feeler gauge should slide between the rocker arm and valve stem with a slight amount of resistance, without binding. See Figure 30.

MAINTENANCE & REPAIR INSTRUCTIONS

REPLACING THE SPARK PLUG

Use a Champion RDZ19H spark plug (or equivalent). The correct air gap is 0.635 mm (0.025 in.) 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.

3. Replace cracked, fouled or dirty spark plug. Set the air gap at 0.635 mm (0.025 in.) using a feeler gauge. See Figure 32.

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

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:

12.3-13.5 N•m (110-120 in.•lb.)

Do not over tighten.

0.635 mm

(0.025 in.)

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 petrol (gasoline) from the fuel tank into a container. Do not use petrol that has been stored for more than 60 days. Dispose of the old fuel 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.

NOTE: Remove the spark plug and drain all of the oil from the cylinder before attempting to start the trimmer after storage.

3. Thoroughly clean the unit and inspect for any loose or damaged parts. Repair or replace damaged parts and tighten loose screws, nuts or bolts. The unit is ready for storage.
