2. Power On: Locate the power switch on the model (refer to your pictorial guide for exact location). Flip the switch to the 'ON' position.
3. Observation: The electric motors will activate, causing the crankshaft, pistons, and valvetrain to move, simulating the operation of a real four-cylinder engine. Observe the synchronized movement of the internal components.
4. Power Off: To turn off the model, flip the power switch to the 'OFF' position.

Note: The model is designed for demonstration and educational purposes. It does not generate actual combustion or exhaust. The sound produced is from the electric motors and mechanical movement.

6. Maintenance

To ensure the longevity and optimal performance of your SainSmart Teching Four-Cylinder Mini Engine Model, follow these maintenance guidelines:

• Cleaning: Regularly wipe the model with a soft, dry cloth to remove dust and debris. Avoid using abrasive cleaners or solvents, as they may damage the metal finish.
• Lubrication: Periodically apply a small amount of light machine oil to moving parts, such as the crankshaft bearings and camshafts, to ensure smooth operation. Refer to the assembly guide for recommended lubrication points.
• Storage: Store the model in a clean, dry environment away from direct sunlight and extreme temperatures.
• Battery Care: If storing the model for an extended period, ensure the battery is partially charged (around 50%) to prolong its lifespan. Do not store with a fully depleted or fully charged battery for long durations.
