OPERATING INSTRUCTIONS

•Cut while swinging the upper part of your body from right to left.

•Always release the throttle trigger and allow the engine to return to idle speed when not cutting.

WARNING: The blade continues to spin after the engine is turned off. The coasting blade can seriously cut you if accidentally touched.

•Swing the unit in the same direction as the blade spins, which increases the cutting action.

•Move forward to the next area to be cut after the return swing and plant feet again.

•The cutting blade is designed with a second cutting edge, which can be used by removing the blade, turning it upside down, and reinstalling it.

WARNING: Do not sharpen the cutting blade. Sharpening the blade can cause the blade tip to break off while in use. This can result in severe personal injury to yourself or others. Replace the blade.

To reduce the chance of material wrapping around the blade, follow these steps:

•Cut at full throttle.

•Swing the unit into material to be cut from your right to your left (Fig. 28).

•Avoid the material just cut as you make the return swing.

WARNING: Do not clear away cut material with the engine running or blade turning. To avoid serious personal injury, turn off engine. Allow the blade to stop before removing materials wrapped around the blade shaft.

780r specifications

The Ryobi 780R is a powerful and reliable gas-powered string trimmer known for its exceptional performance and user-friendly features. Designed for both professionals and homeowners, this tool offers versatility and efficiency for tackling tough trimming jobs around the yard.

One of the standout features of the Ryobi 780R is its robust 30cc 2-cycle engine. This engine provides ample power to handle thick weeds and overgrown grass, ensuring a clean and precise cut with every pass. The lightweight design of the trimmer enhances maneuverability, making it easy to navigate around obstacles such as trees, flower beds, and garden furniture.

The trimmer is equipped with a premium 18-inch cutting swath, allowing for a wider range to be covered in a single pass. This feature can significantly reduce the time required to complete larger trimming tasks. Additionally, the variable speed throttle gives users the flexibility to adjust the cutting power based on the density of the vegetation, offering greater control.

This functionality minimizes downtime and allows users to focus on the task at hand. The dual-line setup also enhances cutting efficiency, making it a great choice for tougher vegetation.

In terms of comfort, the Ryobi 780R incorporates ergonomic handle designs that reduce user fatigue during extended use.
