2. Safety Information
Operating this engine safely is paramount. Failure to follow safety instructions can result in serious injury or property damage. Always observe the following precautions:
- Read the Manual: Understand all instructions and warnings before operation.
- Ventilation: Operate the engine in a well-ventilated area. Exhaust fumes contain carbon monoxide, which is a colorless, odorless, and deadly gas.
- Fuel Handling: Handle gasoline with extreme care. It is highly flammable. Store fuel in approved containers away from ignition sources. Do not refuel a hot or running engine.
- 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 flywheel and shaft.
- 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 safety gear, including eye protection and gloves, when operating or servicing the engine.
- Engine Placement: Ensure the engine is placed on a level, stable surface before starting.
3. Setup
Before starting the engine for the first time, perform the following setup steps:
- Unpacking: Carefully remove the engine from its packaging. Inspect for any shipping damage.
- Add Engine Oil: The engine is shipped without oil. Fill the crankcase with 0.16 gallons (approximately 0.6 liters) of SAE 10W-30 or API SJ (or higher) high-quality detergent oil. Do not overfill. An oil funnel is included for convenience.
- Add Fuel: Fill the fuel tank with fresh, unleaded gasoline. The fuel tank capacity is 0.95 gallons. Do not use old or contaminated fuel. Ensure the fuel cap is securely tightened.
- Check Air Filter: Ensure the air filter element is clean and properly installed.
- Mounting: Securely mount the engine to your equipment using appropriate hardware. The engine features anti-vibration pads for stable operation.

4. Operating Instructions
Follow these steps to start and operate your Aceup Energy gas engine:
4.1 Starting the Engine (Recoil Start)
- Fuel Valve: Open the fuel valve (usually located at the bottom of the fuel tank).
- Choke: If starting a cold engine, move the choke lever to the 'CLOSED' position. For a warm engine, the choke may not be necessary.
- Engine Switch: Ensure the engine switch is in the 'ON' position.
- Pull Starter: Grasp the recoil starter handle firmly. Pull slowly until resistance is felt, then pull quickly and smoothly to start the engine. Do not let the rope snap back; guide it gently.
- Choke Adjustment: Once the engine starts, gradually move the choke lever to the 'OPEN' position as the engine warms up.
4.2 Stopping the Engine
- Throttle: Reduce the engine speed to idle.
- Engine Switch: Move the engine switch to the 'OFF' position.
- Fuel Valve: Close the fuel valve to prevent fuel leakage and ensure safe storage.

5. Maintenance
Regular maintenance is crucial for the longevity and optimal performance of your engine. Refer to the following guidelines:
5.1 Maintenance Schedule
- Before Each Use: Check engine oil level, fuel level, and air filter condition.
- Every 25 Hours or Annually: Clean or replace air filter element (more frequently in dusty conditions).
- Every 50 Hours or Annually: Change engine oil. Inspect spark plug.
- Every 100 Hours: Clean spark plug and adjust gap. Inspect fuel lines.
5.2 Specific Maintenance Tasks
- Air Filter: The air filter element should be cleaned or replaced every 25 hours of operation or more frequently in dusty environments. Refer to the sticker on the air filter housing for specific instructions.
- Engine Oil: Drain old oil when the engine is warm. Refill with 0.16 gallons of SAE 10W-30 oil.
- Spark Plug: Use the included spark plug wrench to remove the spark plug. Inspect for wear or fouling. Clean or replace as needed. The recommended spark plug gap is 0.6-0.8 mm, and the torque is 18-22 N.m.
- Fuel System: Periodically check fuel lines for cracks or leaks. If storing the engine for an extended period, drain the fuel tank and carburetor to prevent fuel degradation.

6. Troubleshooting
This section addresses common issues you might encounter with your engine. For problems not listed here, contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Engine will not start | No fuel, old fuel, engine switch OFF, choke incorrect, fouled spark plug, low oil. | Add fresh fuel, turn engine switch ON, adjust choke, clean/replace spark plug, add oil. |
| Engine runs poorly | Dirty air filter, stale fuel, incorrect choke setting, spark plug issue. | Clean/replace air filter, use fresh fuel, adjust choke, inspect spark plug. |
| Engine smokes excessively | Overfilled oil, wrong oil type, worn engine components. | Check oil level and type. If problem persists, seek professional service. |
6.1 Frequently Asked Questions
- Q1: What is the recommended operating temperature range, and what oil should be used?
Operating Temperature Range: -18°C (0°F) to 40°C (104°F). When operated above 25°C (77°F), there may be a decrease in power. SJ 10W-40 oil is recommended, and other high-quality detergent oils (API SJ or higher) are also acceptable. - Q2: Why does the engine arrive with some oil residue?
The engine undergoes functional testing at the factory prior to delivery. This process may leave minimal residual oil (or a fuel odor), which is a normal phenomenon and does not affect its use.
