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). Alcoholblended 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 30 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

USING FUEL ADDITIVES

The bottle of 2-cycle oil contains a fuel additive which 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 in accordance to Federal, State and

Local regulations.

FUELING THE UNIT

1. Turn unit on its side, with the fuel cap facing up, and remove the fuel cap.

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.

4. Reinstall the fuel cap.

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

MIXING RATIO - 40:1

OIL AND FUEL INFORMATION

WARNING:

To avoid serious personal injury and damage to the

unit, shut the unit off before removing or installing an attachment.

CAUTION: Before operating this unit, be sure that the release

button is fully snapped into the primary hole (Fig. 5), and that the knob (Fig. 3) is securely tightened.

WARNING:

Before you begin using any attachment, read and understand the manual that came with

the attachment. Follow all safety information contained within.

CAUTION:

These attachments are to be snapped into the primary hole only. Using the wrong hole

could lead to personal injury or damage to the unit.

HOLDING THE 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

The Bump Head™ cutting head allows the release of trimming line without stopping the engine. To release more line, 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 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).

LINE INSTALLATION

This section covers both SplitLine® and standard single line installation.

Always use original equipment manufacturer 0.095 in. (2.41 mm) replacement line. Line other than the specified may make the engine overheat or fail.

There are two methods to replace the trimming line:

• Wind the inner reel with new line

• Install a prewound inner reel

Removing the Existing Inner Reel

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

Remove the inner reel from the outer spool (Fig. 13).

3. Remove spring from the inner reel (Fig. 13).

4. Use a clean cloth to clean the inner reel, spring, shaft, and inner surface of the outer spool.

5. Check the indexing teeth on the inner reel and outer spool for wear (Fig. 14). If necessary, remove burrs or replace the reel and spool.

NOTE: Always use the correct line length when

installing trimming line on the unit. The line may not release properly if the line is too long.

Single Line Installation

Go To Step 8 for SplitLine® Installation:

6. Take approximately 20 feet (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. 15). Pull the line through the inner reel so that the loop is as small as possible.

7. Wind the lines in tight even layers onto the reel (Fig. 16). Wind the line in the direction indicated on the inner reel. Place an index finger between the two lines to stop the lines from overlapping. Do not overlap the ends of the line. Proceed to step 12.

8. Take approximately 10 feet (3 m) of new trimming line. Insert one end of the line through one of the two holes in the inner reel (Fig. 17). Pull the line through the inner reel until only about 4 inches is left out.

9. Insert the end of the line into the open hole in the inner reel and pull the line tight to make the loop as small as possible (Fig. 17).

10. Before winding, split the line back about 6 inches.

11. Wind the line in tight even layers in the direction indicated on the inner reel.

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

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

13. Insert or slide the ends of the line through or into the eyelets in the outer spool and place inner reel with spring inside the outer spool (Fig. 19). Push the inner reel and outer spool together.

NOTE: The spring must be assembled on the inner reel before reassembling the cutting head.

14.

While holding the inner reel and outer spool, grasp the ends and pull firmly to release the line from the holding slots in the spool.

15. Hold the inner reel in place and install the bump knob by turning clockwise. Tighten securely.

INSTALLING A PREWOUND REEL

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

2. Remove the old inner reel from the outer spool (Fig. 13).

3. Remove the spring from the old inner reel (Fig. 13).

4. Place the spring in the new inner reel.

NOTE: The spring must be assembled on the inner reel before reassembling the cutting head.

5. Insert or slide the ends of the line through or into the eyelets in the outer spool (Fig. 19).

6. Place the new inner reel inside the outer spool. Push the inner reel and outer spool together. While holding the inner reel and outer spool, grasp the ends and pull firmly to release the line from the holding slots in the spool.

7. Hold the inner reel in place and install the bump knob by turning clockwise. Tighten securely.

INSTALLATION OF THE SPEEDLOCK™ Removing the Existing Inner Reel

Refer to Removing the Existing Inner Reel in the Maintenance and Repair Instructions section that can be found in the operator’s manual.

Installing the SpeedLock™

1. After removing the inner reel, place the SpeedLock™ onto the shaft, making sure to align the arrows with the eyelets in the outer spool (Fig. 20).

2. Place the spring over the shaft and into the recess in the SpeedLock™ Spool (Fig. 20).

3. While holding the outer spool in place, insert the bolt located in the Bump Knob™ through the end of the spring and into the end of the shaft (Fig. 20).

4. While slightly compressing the spring, screw the Bump Knob™ clockwise into the shaft (Fig.

20). Tighten Securely.

Installing the Trimming Line

1. Align the arrows on the SpeedLock™ with the eyelets on the outer spool (Fig. 21).

AIR FILTER MAINTENANCE

Cleaning the Air Filter

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 by unscrewing the cover screw (Fig. 24).

2. Remove the air filter (Fig. 24).

3. Wash the filter in detergent and water. Rinse the filter thoroughly and allow it to dry.

4. Apply enough clean SAE 30 motor oil to lightly coat the filter.

5. Squeeze the filter to spread and remove excess oil.

6. Replace the air filter (Fig. 24).

NOTE: Operating the unit without the air filter will VOID the warranty.

7. Reinstall the air filter cover. Insert the hooks on the air filter housing into the slots on the air filter cover (Fig. 25).

8. Swing the air filter cover to the right and align the cover screw with the cover screw hole (Fig. 25). Tighten the cover screw to secure the air filter cover.

NOTE: Do not over tighten as this may strip the screw. ADJUSTING THE IDLE SPEED NOTE: Careless adjustments can seriously damage the unit. A qualified service

dealer should make carburetor adjustments.

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. Refer to Starting and Stopping.

2. Release the throttle control and let the engine idle. If the engine stops, use a small Phillips screwdriver to turn the idle speed screw clockwise, 1/8 of a turn at a time (as needed) until the engine idles smoothly (Fig. 26).

3. If the engine is idling too quickly, turn the idle speed screw counterclockwise, 1/8 of a turn at a time (as needed) to reduce the idle speed (Fig. 26).

Checking the fuel, cleaning the air filter, and adjusting the idle speed should solve most engine problems. If not, and any of the following conditions are true, take the unit to a qualified service dealer:

• the engine will not idle

• the engine hesitates or stalls on acceleration

• there is a loss of engine power

WARNING: To avoid serious personal injury, always stop the engine and allow it to cool before

cleaning or maintaining the unit.
