3. Install the bolt, washer, wing nut and tighten.

ADJUSTING THE D-HANDLE

1. Loosen the wing nut. It is not necessary to remove

the wing nut, washer and bolt.

3. While holding the unit in the operating position

(Fig. 7), position the D-handle to the location that provides you the best grip, and tighten the wing nut (Fig. 1).

INSTALLING THE CUTTING ATTACHMENT

1. Place the cutting attachment guard onto the shaft

tube above the clamp assembly (Fig. 2).

2. Push the cutting attachment guard down to the top

of the string head assembly and then rotate the cutting attachment guard until the screw holes align and the guard fits into the recessed pocket (Fig. 3).

2. Rotate the D-handle to place the grip above the top

of the shaft housing.

OIL AND FUEL MIXING INSTRUCTIONS

Use high quality oil formulated for use in 2-cycle, aircooled engines. Mix the oil according to the instructions on the 2-cycle engine oil container, 40:1 (2.5 %). 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. Thoroughly mix the proper ratio of 2-cycle engine oil with unleaded petrol, 40:1 (2.5 %). Do not mix them directly in the tank.

RECOMMENDED FUEL TYPE

Always use clean, fresh, unleaded petrol (gasoline). OPERATING INSTRUCTIONS STARTING INSTRUCTIONS NOTE: Squeeze the throttle control until the engine has started and warmed up.

1. Mix petrol (gasoline) with oil. Fill fuel tank with fuel/oil

mixture. See Oil and Fuel Mixing Instructions.

2. Put the ignition switch in the ON (I) position (Fig. 4).

3. TIP: When you are trying to start a unit that has

been dormant for a while (or if it is brand new or difficult to start), be sure to press and release the primer bulb 20 times. Fully press and release primer bulb slowly 10 times. You should feel and see fuel in the bulb (Fig. 5). If fuel hasn't entered the bulb, press three more times, or keep pressing until it does.

4. Place the choke lever in Position 1 (Fig. 5).

TIP: Make sure choke lever locks into (1) position.

5. With the unit on the ground, squeeze the throttle

control and hold. 700: Pull starter rope briskly 3 times (Fig. 6). 710: Pull the starter rope out with a controlled and steady motion 3 times.

6. Place the choke lever in Position 2 (Fig. 5).

7. 700: Pull starter rope briskly 1 to 3 times to start the

engine (Fig. 6). 710: Pull the starter rope out with a controlled and steady motion 1 to 5 times to start the engine (Fig. 6). OPERATING INSTRUCTIONS 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.

8. If the engine does not start, repeat steps 3 through 7.

9. Keep throttle trigger depressed to warm up engine.

After the engine warms up for 10 to 15 seconds, place the choke lever in Position 3 (Fig. 18). NOTE: If the engine floods while attempting to start, place the choke lever in the Position 3, squeeze the throttle trigger, and pull the starter rope briskly. The engine should start within three (3) to eight (8) pulls. NOTE: Choking is not required when starting a warm engine. Start a warm engine with the ignition switch in the ON position and the choke lever in Position 2. STOPPING INSTRUCTIONS A blade in the cutting attachment guard will cut 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 line release is attempted in tall grass, the engine may stall. Some line breakage will occur from:

• Forcing the line into objects such as walls or fence posts

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 200 mm (8 in.) by working from top to bottom in small increments to avoid premature line wear or engine drag.
• Cut from left to right whenever possible. Cutting to the right improves the unit's cutting efficiency. Clippings are thrown away from the operator.

2. Put the ignition switch in the OFF (O) position (Fig. 4).

• Slowly move the trimmer into and out of the cutting area at the desired height. Move either in a forwardbackward or side-to-side motion. Cutting shorter lengths produces the best results.

ADJUSTING TRIMMING LINE LENGTH

DECORATIVE TRIMMING 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. 8) 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. Decorative trimming is accomplished by removing all vegetation around trees, posts, fences, etc. Rotate the whole unit so that the cutting attachment is at a 30° angle to the ground (Fig. 9).

1. Release your finger from the throttle trigger (Fig. 4).

Allow the engine to cool down by idling.

MAINTENANCE AND REPAIR INSTRUCTIONS

2. Remove the inner reel from the outer spool (Fig. 11).

This section covers both Split-Line™ and standard single line installation. Always use 2.0 mm. (0.080 in.) replacement line. The engine may overheat or fail if you use a line size other than specified. There are two methods to replace the trimming line.

• Wind the inner reel with new line

3. Remove spring from the inner reel (Fig. 11).

• Install a prewound inner reel Winding the Existing Inner Reel

1. Hold the outer spool with one hand and unscrew the

Bump Knob counterclockwise (Fig. 10). Inspect the bolt inside the Bump Knob to make sure it moves freely. Replace the Bump Knob if damaged.

4. Use a clean cloth to clean the the inner reel, spring,

2. Insert the four (4) screws into the holes in the air

filter/muffler cover (Fig. 19) and tighten. Use a T-20 Torx bit screwdriver. Do not over tighten. Do not force. Check Fuel Mixture Old and/or improperly mixed fuel is usually the reason for the unit not running properly. Drain and refill the tank with fresh, properly mixed fuel prior to making any adjustments.

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 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 Adjuster If after checking the fuel mixture and cleaning the air filter the engine still will not idle, adjust the idle speed adjuster as follows.

1. Start the engine and let it run about 2–3 minutes at a

high speed (full throttle) to warm up.

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

the engine stops, insert a small phillips screwdriver into the hole in the air filter/muffler cover (Fig. 23). Turn the idle speed adjuster in, clockwise, 1/8 of a turn at a time (as needed) until the engine idles smoothly. See Specifications for idle RPM. NOTE: The unit does not have a clutch and the cutting attachment continues rotating when the engine is idling.

3. To reduce the idle speed, turn the idle speed

adjuster counterclockwise 1/8 of a turn at a time (as needed). Checking the fuel mixture, cleaning the air filter, and adjusting the idle speed screw should solve most engine problems. If not 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.

REPLACING THE SPARK PLUG

Use a Champion RDJ7Y spark plug (or equivalent). The correct air gap is 0.5 mm (0.020 in.). Remove the plug after every 50 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.

3. Replace cracked, fouled or dirty spark plug. Set the

air gap at 0.5 mm (0.020 in.) using a feeler gauge (Fig. 24).

4. Install a correctly gapped spark plug in the cylinder

head. Tighten by turning the 5/8 in. socket clockwise until snug. Do not over tighten. CLEANING 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 in a dry place, locked up or up-high to prevent unauthorized use or damage. Keep 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 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.

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 30 ml (1 oz.) of any high quality motor oil or 2cycle 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 for any loose

or damaged parts. Repair or replace damaged parts and tighten loose screws, nuts or bolts. The unit is ready for storage.

Store the unit in a dry place, locked up or up-high to prevent unauthorized use or damage. Keep out of the reach of children.
