SOLUTION

 

 

 

Engine will not start:

1.Switch not ON.

 

2.No spark.

3.No fuel.

4.Flooded engine.

5.Starter rope pulls harder now than when new.

1.Move switch to ON.

2.Check spark. Remove spark plug. Reattach the spark plug cap and lay spark plug on metal cylinder. Pull the starter rope and watch for spark at spark plug tip. If there is no spark, repeat test with a new spark plug.

3.Push primer bulb until bulb until fuel is visible in the bulb. If fuel is not apparent, the primary fuel delivery system is blocked. Contact a servicing dealer. If primer bulb fills, engine may be flooded (see next item).

4.Remove spark plug. NOTE: Do not let gas spill on the ground. Move choke lever to “RUN” and pull starter cord 10 to 15 times. This will clear excess fuel from engine. Clean and reinstall spark plug. Pull starter three times with choke lever at “RUN”. If engine does not start, move choke lever to “CHOKE” and repeat normal starting procedure. If engine still fails to start, repeat procedure with a new spark plug.

3.Turn “H” needle clockwise 1/16 turn. See Figure 12.

4.Contact a servicing dealer.

NOTE: The carburetor adjustment needle(s) are equipped with plastic cap(s) that prevents counterclockwise rotation from the original factory adjustment. If your unit exhibits specific performance problem(s) where the Trouble Shooting Section recommends a counterclockwise needle adjustment and no adjustments have been made since original purchase, the unit should be taken to a factory authorized service dealer for repair. In most cases, the needed adjustment is a simple task for the factory trained service representative.

UT08570, UT08571 specifications

The Homelite UT08571 and UT08570 are powerful and efficient string trimmers designed for homeowners and professional landscapers alike. Engineered to simplify garden maintenance, these trimmers are equipped with advanced features that enhance performance and ease of use.

One of the standout characteristics of both models is their lightweight design, which promotes maneuverability while minimizing user fatigue. Weighing in at just under 10 pounds, these trimmers allow for extended use without discomfort. The ergonomic handle design provides a more natural grip, contributing to a seamless trimming experience.

The UT08571 and UT08570 are powered by robust 25cc two-cycle engines. This engine technology delivers ample power to tackle thick weeds and tall grass with ease. The engines ensure efficient fuel consumption, allowing for longer run times before refueling, which is a significant advantage for those undertaking larger landscaping projects.

Both models showcase a bump feed head system that allows for quick and easy line advancement. Simply bumping the trimmer head against the ground releases more string, ensuring that users can maintain continuous operation without the need to stop and manually adjust the line. The dual line cutting feature enhances efficiency, allowing for a wider cutting path of 17 inches, which further speeds up the trimming process.

In terms of technology, the trimmers are designed with a centrifugal clutch that engages the trimmer head only when the throttle is pressed. This feature reduces wear on the engine and string, extending the lifespan of the tool. Additionally, the translucent fuel tank allows users to monitor fuel levels without opening the tank, reducing the risk of spills and facilitating easier refueling.

For those looking for versatility, both models are compatible with various attachments, enabling users to convert them for different landscaping tasks, such as edging or pruning. This adaptability makes the UT08571 and UT08570 excellent additions to any gardening toolkit.

Safety considerations are also paramount in the design of these trimmers. They come with protective guards to shield users from debris, ensuring a safer trimming experience. With easy start technology, both models feature a simple start mechanism that minimizes the effort required to fire up the engine.

Overall, the Homelite UT08571 and UT08570 string trimmers are a blend of innovation, efficiency, and user-friendly features, making them ideal choices for maintaining a pristine yard or garden. Whether you are a seasoned gardener or just starting, these trimmers provide reliability and power for all your trimming needs.
