Operation

• Save all instructions

Control Identification and Use:

Recommendations:

1. Your Trimmer performs best when the engine operates at high speed and the tips of the line cut the vegetation. Do not force the trimmer line into grass

faster than the Trimmer’s cutting speed permits.

2. The tips of the line can cause damage to trees, shrubs and fences. To avoid damage in these conditions, you may choose to run the engine at lower speeds and should carefully monitor the location of the cutting line.

3. Because the cutting head can be pivoted to the right side, plan to trim objects (fences, buildings, etc.) in a clockwise manner.

4. When trimming next to wire type fencing, avoid cutting-line contact with the fence. Contact will result in rapid line wear. Likewise, contact with concrete and brick surfaces will result in rapid line wear.

Thoroughly inspect the area where the Trimmer is to be used and remove all foreign objects. Your equipment can throw small objects at high speed causing personal injury or property damage.

Keep all children and bystanders at least 50 ft (15 m) away when operating. Stop machine if anyone enters the area.

WARNING

1. Throttle:

The throttle is located on the top crossbar on the upper handle. Depressing the lever will increase the engine speed. At idle speed the clutch is disengaged and the trimmer head will not turn. As engine speed is increased, the automatic clutch will engage and rotate the trimmer head. Upon release, the throttle lever is spring loaded to return to idle speed. (Fig. 14)

2. Swivel to offset trimmer head:

Your wheeled string trimmer mower is designed with the ability to offset the trimming head from a centered position to a right side position. This is accomplished by depressing the finger control on the right upper handle. By depressing the finger control, the head becomes unlocked and can be swiveled to two positions to the right. Upon release of the finger control, a pin will lock the trimmer head into the desired position. Swiveling the trimmer head allows for easy mowing / trimming around obstacles such as posts or trees and under fences. (Fig. 15)

3. Bevel trimming adjustment:

The line will normally cut approximate 2 inches (50 mm) high. When it is desired that the line cut closer to the ground, a bevel adjustment is available. A handle is located just in front of the left wheel. This handle can be deflected outward and rotated to two different positions. This will position the trimmer head at an angle and allow the line to cut closer to the ground. This is especially useful when trimming next to raised sidewalks or building foundations. (Fig. 16)

4. Start / Stop switch:

An ignition switch is located on the engine air filter housing. The switch must be in the “On” position for the engine to run. Moving the switch to the “Off” position will stop the engine. (Fig. 17)

Operation (Continued)

• Save all instructions

Starting Engine:

Keep all parts of your body away from cutting area, the rotating trimmer lines and hot surfaces.

NOTE: DO NOT depress the throttle lever until engine starts and runs.

NOTE: When the weather gets cold, please allow the engine to warm up at idle for longer period of time, before engaging to RUN/WARM START position.

WARNING

The 2-cycle engine on your Trimmer requires that fuel and 2-cycle engine oil be pre-mixed before adding to the

trimmer’s fuel tank. To mix the fuel/ 2-cycle oil:

1. Use fresh unleaded gasoline with an octane rating of 87 or higher. Do not use gasoline containing more than 10% ethanol.

NOTICE

Use of gasoline containing more than 10% ethanol can damage Trimmer. Use of non-ethanol gasoline is best. We recommend the continuous use of a fuel additive/ stabilizer to counteract the effects of ethanol. These additives also prolong the shelf life of gasoline.

2. Always use 2-cycle oil that meets or exceeds JASO – FC specifications and is intended for mixing at a fuel/oil ratio of 50:1

3. Do not use automotive or 2-cycle marine outboard oil.

These will damage your Trimmer’s engine and void

the warranty.

4. Always mix the gasoline and 2-cycle oil in a container approved for gasoline. Never mix fuel directly in the

trimmer’s fuel tank.

5. Follow instructions on 2-cycle oil container for mixing fuel. Mix gasoline and 2-cycle oil at a ratio of 50:1. A mixture with a 50:1 ratio is obtained by mixing 1 gallon (4 liters) of gasoline with 2.6 ounces of oil (77 ml). After adding oil to gasoline, shake container momentarily to ensure proper mixing.

6. Mix only enough fuel for your immediate needs. Do not store pre-mixed fuel.

7. Stop engine and allow to cool before refueling.

8. To fill the Trimmer’s fuel tank with the gasoline/oil

mixture, place the Trimmer upright on the ground or on a sturdy bench and wipe and any debris from around the fuel cap.

9. Remove fuel cap slowly and use a funnel to pour the mixture into the tank, and replace the fuel cap.

10. Avoid spilling fuel or oil. Wipe up all fuel spills.

11. Move at least 10 ft (3 m) away from fueling site before starting engine.

Before Starting Engine:

Mixing Fuel / 2-Cycle Oil

Do not smoke or allow smoking near fuel or the Trimmer. Mix and pour fuel outdoors WHERE THERE ARE NO SPARKS OR FLAMES.

WARNING

Recommendations (cont.):

5. Do not allow the trimmer head metal bowl to ride on top of concrete or asphalt surfaces. This will cause wear to the metal bowl. The bowl was designed to ride on grass surfaces.

6. It is recommended that the line be replaced when it is worn to approximately ½ the original length. This will help maintain a high tip speed and result in a clean cut. It is strongly recommended that the engine cooling air screen be wiped clean at every string change. This will prevent engine overheating.

CAUTION

1. Release the throttle lever and allow the engine to idle for a few moments.

2. Move the Ignition Switch to the “OFF” position.

WARNING

Techniques / Applications:

Thoroughly inspect the area where the Trimmer is to be used and remove all foreign objects. Your equipment can throw small objects at high speed causing personal injury or property damage.

Your Trimmer is most effective when using the tips of the trimmer line for trimming grass and other vegetation. Do not

force the trimmer line into grass or vegetation faster than Trimmer’s cutting speed permits. Forcing the Trimmer will

cause your Trimmer to be less effective, and may cause the engine to overheat.

Trimming Tip

To extend the life of the trimmer line, keep the trimmer line moist. If not kept moist, the nylon line will become dry and brittle. Keep extra trimmer line in a container of water. The line will stay flexible and easy to change. A flexible line will also last longer.

It is recommended that the engine air intake screen be cleaned every time the trimmer line is replaced. Failure to keep the air intake screen clean may result in overheating and damage to engine. (See instructions under the Maintenance section)
