Operation

Before operation: Read the operator's manual carefully. Examine the cutting equipment to ensure it is correctly attached and adjusted. Fill the fuel tank and oil tank, and check the oil level.

Starting the product: Ensure the ignition cable is connected to the spark plug. Stay behind the product. Hold the engine brake handle against the handlebar. Hold the starter rope handle with your right hand. Slowly pull out the starter rope until you feel some resistance. Pull with force to start the engine.

Stopping the product: To stop the drive only, release the drive bail. To stop the engine, release the engine brake handle.

Maintenance

Maintenance schedule: Perform a general inspection, check the oil level, and clean the product daily. Replace the oil after the first 5 hours of use, then after every 50 hours of use. Examine the cutting equipment, cutting cover, and engine brake handle daily. Examine the muffler, air filter, and fuel system monthly. Examine the spark plug and clean the cooling fins on the cylinder each season.

Blade replacement: Lock the blade with a block of wood. Remove the blade bolt and the blade. Examine the blade support and blade bolt for damage. Examine the engine shaft to ensure it is not bent. When attaching the new blade, point the angled ends of the blade in the direction of the cutting cover. Ensure the blade is aligned with the center of the engine shaft. Lock the blade with a block of wood, attach the spring washer, and tighten the bolt and washer with a torque of 45–60 Nm. Pull the blade around by hand to ensure it turns freely.

Engine troubleshooting

If the engine does not start, check if the ignition cable is connected, the fuel tank is empty, the fuel is old, there is dirt in the carburetor or fuel line, the spark plug is defective, or there is fuel on the spark plug. If the engine does not operate smoothly, check the ignition cable, fuel line, fuel tank cap, fuel system, air filter, or carburetor adjustment.
