2. Safety Information

Always observe the following safety precautions to reduce the risk of injury or damage:

• Read the Manual: Understand all instructions and warnings before operating the engine.
• Ventilation: Operate the engine in a well-ventilated area. Engine exhaust contains carbon monoxide, a colorless, odorless, poisonous gas.
• Fuel Handling: Handle gasoline with extreme care. It is highly flammable. Store fuel in approved containers and in a well-ventilated area away from ignition sources.
• Hot Surfaces: The engine and exhaust system become very hot during operation and remain hot for a period after shutdown. Avoid contact to prevent burns.
• Moving Parts: Keep hands, feet, and clothing away from moving parts such as the recoil starter and shaft.
• Engine Shutdown: Always turn off the engine and allow it to cool before performing any maintenance or inspections.
• Children and Pets: Keep children and pets away from the engine during operation and while it is cooling down.
• Personal Protective Equipment (PPE): Wear appropriate PPE, such as safety glasses and gloves, when operating or maintaining the engine.

4. Setup

Before starting your engine for the first time, ensure the following steps are completed:

1. Add Engine Oil:

   The engine is shipped without oil. Fill the crankcase with SAE 10W/30 engine oil. The oil capacity is 0.16 gallons (approximately 0.6 liters). Use the included oil funnel for easier filling. Do not overfill.

2. Add Fuel:

   Fill the fuel tank with fresh, unleaded gasoline. The fuel tank capacity is 0.95 gallons (approximately 3.6 liters). Do not use old or contaminated fuel. Ensure the fuel cap is securely tightened after filling.

3. Initial Run-in:

   For optimal engine longevity, it is recommended to run the engine at idle speed for approximately one hour during its first use. This helps to properly break in the piston and rings before subjecting the engine to heavy loads.

5. Operating Instructions

Follow these steps to start and operate your Aceup Energy gas engine:

1. Fuel Valve: Ensure the fuel valve is in the "ON" position.
2. Choke: If the engine is cold, move the choke lever to the "CHOKE" position. For a warm engine, the choke may not be necessary.
3. Engine Switch: Set the engine switch to the "ON" position.
4. Recoil Start: Grasp the recoil starter handle firmly and pull it slowly until resistance is felt, then pull quickly and smoothly to start the engine. Repeat if necessary.
5. Choke Adjustment: Once the engine starts and runs smoothly, gradually move the choke lever to the "RUN" position.
6. Stopping the Engine: To stop the engine, move the engine switch to the "OFF" position. For storage, it is advisable to close the fuel line shut-off valve and let the engine run until it runs out of fuel in the carburetor. This helps prevent issues caused by ethanol in gasoline.

6. Maintenance

Regular maintenance is crucial for the longevity and performance of your engine. Always ensure the engine is off and cool before performing any maintenance.

• Air Filter Maintenance:

  Clean the air filter element every 50 hours of operation, or more frequently if operating in dusty conditions. Refer to the air filter housing for specific instructions on removal and cleaning. A dirty air filter can reduce engine performance and lifespan.

• Oil Change:

  Change the engine oil after the first 20 hours of operation, and then every 50-100 hours or annually, whichever comes first. Use SAE 10W/30 oil. Refer to the engine's oil drain plug location for proper drainage.
• Spark Plug Inspection:

  Inspect the spark plug (type F6TC) periodically. Clean or replace it if it is fouled or worn. Use the included spark plug wrench for removal and installation. Ensure the gap is set correctly according to specifications.

• General Cleaning:

  Keep the engine clean, especially cooling fins and air intake areas, to prevent overheating.
