8. User Guide

8.1 Pre-Startup Preparation

1. Check Package Contents: Ensure you have received the complete package.

2. Read User Guide: Familiarize yourself with the user guide to understand features, precautions, and safe operating procedures.

8.2 Installation and Connections

1. Install Valve Plates: Attach the high-temperature resistant 304 one-way valve plates to the engine.

2. Connect Fuel Tank and Hose: Ensure a secure connection between the fuel tank and hose.

3. Install Battery: Place the battery in the battery box and connect it to the engine. Ensure correct polarity to prevent damage.

4. Prepare Electronic Ignition: Check the battery status of the electronic ignition and ensure it functions correctly.

8.3 Engine Startup

1. Ensure Safety Environment: Only use the engine outdoors to minimize noise and emissions impact on the surroundings.

• 1.Connect all components according to the diagram , add 92# or higher octane gasoline fuel to both fuel tanks , and connect all circuits and oilpipes.
• 

• 2. It is recommended to fix the engine on the board, align the spray with the air inlet of the engine, and then fix the spray on the board. And ensure that the minimum fuel level in the fuel pipe connected to tank 1 is about 30mm lower than the liquid level at the engine port.

• 
• 

• 3.Put 8 AA batteries into the battery box and check if the battery box switch is turned off. After placing the battery, prepare the above process. You can turn on the power and start the engine (please read the precautions carefully to avoid injury, and prepare fire extinguishing measures).

8.4 Working Principle

1. Combustion Process: The pulse jet model engine utilizes a pulsating combustion process, generating high-pressure gas to propel the jet periodically.

2. Engine Structure: Constructed from carbon steel and aluminum alloy, controlled by high-temperature resistant 304 one-way valve plates. The black high-temperature resistant coating enhances aesthetics.

3. Maximum Thrust: Optimization of the fuel injection chamber allows for a maximum thrust of around 500G, ensuring powerful thrust with reduced weight.

8.5 Safety Precautions Reminder

• Avoid indoor use; only operate the engine outdoors to minimize noise and emission impact.

• Be mindful of gasoline hazards; ensure there are no flammable materials in the surrounding environment.

• Regularly check and clean fuel injection nozzles to prevent dripping.

• Avoid external ignition of the engine to prevent fires caused by scattered gasoline.

• In temperatures below 7 degrees Celsius, starting the engine may require additional time and patience.

8.6 Engine Shutdown

After use, follow the steps outlined in the user guide for shutting down the engine, including turning off the ignition, disconnecting the battery box, and cleaning the engine.
