OPERATING INSTRUCTIONS

HOLDING THE TRIMMER

ADJUSTING TRIMMING LINE LENGTH

WARNING: Always wear eye, hearing, foot and body protection to reduce the risk of injury when operating this unit.

Before operating the unit, stand in the operating position (Fig. 24). Check for the following:

The operator is wearing eye protection and proper clothing.

The right arm is slightly bent, and the hand is holding the shaft grip.

The left arm is straight, and the hand is holding the handle.

The unit is below waist level.

The cutting attachment is parallel to the ground and easily contacts the vegetation to be cut without the operator having to bend over.

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. 25) 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.

Each time the head is bumped, about 1 in

 

(25.4 mm.) of trimming line is released. A blade

 

in the cutting attachment shield 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. Always keep

 

the trimming line fully extended. Line release

 

becomes more difficult as the cutting line

 

becomes shorter.

NOTE: Do not rest the Bump Head™ on

 

the ground.

 

CAUTION: Do not remove or alter

 

the line cutting blade assembly.

 

Excessive line length will make the

 

clutch overheat. This may lead to

 

serious personal injury or damage to

 

the unit.

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

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.
