3. Setup and Assembly

Before first use, ensure all components are correctly assembled and fuel is properly mixed.

3.1 Handlebar Assembly

1. Attach the handlebar to the shaft using the provided clamps and bolts.
2. Adjust the handlebar position for comfortable operation, ensuring easy access to the throttle and stop switch.
3. Tighten all bolts securely.

3.2 Cutting Head Installation

2. Mount the guard securely to the shaft.
3. Attach the desired cutting blade or trimmer head according to the instructions provided with the accessory. Ensure it is properly seated and tightened.

3.3 Fuel Mixing

The EKK-2370 uses a 2-stroke engine. It requires a mixture of unleaded gasoline and 2-stroke engine oil. Refer to the engine oil manufacturer's instructions for the correct mixing ratio (typically 50:1 or 25:1).

• Use fresh, unleaded gasoline with an octane rating of 89 or higher.
• Use high-quality 2-stroke engine oil specifically designed for air-cooled engines.
• Mix the fuel and oil in a separate, approved fuel container. Shake well before pouring into the brush cutter's fuel tank.

4. Operating Instructions

4.1 Starting the Engine

1. Place the brush cutter on a flat, stable surface.
2. Ensure the stop switch is in the 'ON' position.
3. Prime the carburetor by pressing the primer bulb several times until fuel is visible.
4. Move the choke lever to the 'CLOSED' (cold start) position.
5. Pull the starter rope firmly and steadily until the engine fires (usually 1-3 pulls).
6. Once the engine fires, move the choke lever to the 'OPEN' position.
7. Pull the starter rope again until the engine starts and runs smoothly.
8. Allow the engine to warm up for a few minutes before beginning operation.

4.2 Operating the Brush Cutter

• Hold the brush cutter firmly with both hands.
• Maintain a balanced stance.
• Start cutting at a low throttle setting and gradually increase as needed.
• Use a sweeping motion, cutting from right to left for optimal efficiency and debris control.
• Avoid hitting hard objects with the cutting blade.
• If the cutting head becomes jammed, immediately release the throttle and turn off the engine before clearing the obstruction.

4.3 Stopping the Engine

Release the throttle trigger and move the stop switch to the 'OFF' position.

5. Maintenance

Regular maintenance ensures optimal performance and extends the life of your RYOBI EKK-2370 brush cutter. Always disconnect the spark plug cap before performing any maintenance.

5.1 Cleaning

• After each use, clean the exterior of the brush cutter, especially the cutting head and guard, to remove grass, dirt, and debris.
• Ensure cooling fins on the engine are free of obstructions.

5.2 Air Filter

• Check the air filter regularly (daily or after every few hours of use).
• Clean or replace the air filter if it is dirty or clogged. A dirty air filter can reduce engine performance and increase fuel consumption.

5.3 Spark Plug

• Inspect the spark plug periodically (e.g., every 25 hours of operation).
• Clean or replace the spark plug if it is fouled or worn. Ensure the gap is set correctly according to specifications.

5.4 Cutting Blade/Trimmer Head

• Inspect the cutting blade for sharpness and damage before each use. Sharpen or replace dull/damaged blades.
• For trimmer heads, ensure the line is properly loaded and replace worn line as needed.
