Operating & Installation Instructions
1. Removing the Old Trimmer Head

•     Safety First: Remove the battery pack or disconnect the spark plug wire (for petrol models).
•     Lock the Shaft: Use the holding pin or wrench supplied with your trimmer to lock the gear shaft and prevent it from rotating.
•     Removal: Unscrew the old head. Note: Most Ryobi trimmers use a left-hand thread, meaning you must turn it clockwise to loosen it.

2. Installing the RAC155 Head

•     Place the thrust washer onto the splined shaft.
•     Thread the RAC155 head onto the shaft by turning it counter-clockwise (if left-hand thread) until it is securely tightened.

3. Replacing Worn Blades

When the blades become short or chipped, you only need to replace the plastic blades, not the entire head:

•     Turn off the tool and ensure it is completely disconnected from any power source.
•     Push the worn blade inward toward the center of the head to release it from the retention pin, then slide it out.
•     Take a new genuine Ryobi replacement blade, hook it onto the pin, and pull it outward until it clicks securely into place.

Pro Tip: To maximize the lifespan of your plastic blades and prevent them from snapping prematurely against walls or stones, soak them in a bucket of water for 24 hours before their first use. This restores moisture and flexibility to the plastic.
