3. Setup

Before operating your Ryobi RHT25X55R hedge trimmer, ensure it is properly assembled and fueled.

1. Unpacking: Carefully remove all components from the packaging. Verify that all listed items, including the 2-stroke oil, wrench, and HedgeSweep attachment, are present.
2. Fuel Mixing: This is a 2-stroke engine. Mix unleaded petrol with the provided 2-stroke oil at the ratio specified in the engine manual (typically 50:1 or 25:1, refer to the engine manual for exact specifications). Use a clean, approved fuel container for mixing.
3. Fueling: With the engine off and cool, carefully pour the mixed fuel into the fuel tank. Do not overfill. Securely replace the fuel cap.
4. HedgeSweep Attachment: If desired, attach the HedgeSweep accessory to the blade guard as per the instructions provided with the attachment. This helps clear cuttings during operation.

4. Operating Instructions

Follow these steps for safe and effective operation of your hedge trimmer.

1. Starting the Engine (ONE+ EasyStart):
   • Place the hedge trimmer on a flat, stable surface.
   • Ensure the blade is clear of any obstructions.
   • Prime the engine if necessary (refer to engine manual for priming button location and number of presses).
   • Set the choke to the 'START' or 'COLD START' position.
   • Engage the ONE+ EasyStart system (specific method may vary, typically involves pressing a button or engaging a lever).
   • Once the engine fires, move the choke to the 'RUN' or 'HALF CHOKE' position.
   • Allow the engine to warm up for a few moments before full operation.
2. Holding the Trimmer: Grip the front handle and the 5-position rotating rear handle firmly with both hands. Maintain a balanced stance.
3. Trimming Technique:
   • Start trimming from the bottom of the hedge and work upwards for vertical cuts.
   • For horizontal cuts, sweep the trimmer in an arc, keeping the blade parallel to the desired cutting line.
   • Avoid cutting branches thicker than the specified 28 mm capacity.
   • Use the HedgeSweep attachment to clear debris as you cut.
4. Stopping the Engine: Release the throttle trigger and engage the engine stop switch. Ensure the blades come to a complete stop before setting the tool down.
