Operation Instructions
Before operating your Ryobi 40V string trimmer, ensure the cutting head is securely attached and the battery is fully charged. To start, insert the battery and depress the trigger lock-out lever, then squeeze the trigger. Release the trigger to immediately stop the trimmer.
Always maintain a firm grip and keep both hands on the trimmer during operation. For optimal trimming, use a sweeping motion, avoiding prolonged contact with any single area. Prioritize safety and wear appropriate protective gear.
Starting and Stopping the Trimmer
To begin operation, firmly insert the 40V battery into the power head. Depress and hold the safety lock-out lever, then squeeze the trigger to initiate the motor. Releasing the trigger instantly halts the trimmer. Always ensure a secure grip on the handle during startup and operation.

Walk at a steady pace, overlapping each pass slightly to prevent uncut areas. Be mindful of obstacles like trees and fences, adjusting your technique accordingly. Regularly check the string length for peak performance.
Edging Techniques
To achieve clean edges, rotate the trimmer head 180 degrees to utilize the edging guide (if equipped). Hold the trimmer firmly with both hands, maintaining a vertical orientation against sidewalks, driveways, or patios.
Employ short, controlled sweeps, gradually creating a defined edge. Avoid excessive pressure, which can damage the trimmer head or the surface being edged. Regularly clear away grass clippings for a neater appearance. Remember safety glasses are crucial during edging operations.
Maintenance and Care
