Here are the proper operating methods for portable fuel tanks:
- Inspection before use: Examine the tank for any signs of damage, such as cracks, dents, or leaks. Check the fuel cap to ensure it seals tightly and the fuel gauge (if equipped) is working properly.
- Proper fuel selection: Use the appropriate fuel for the intended application. Refer to the equipment's manual to determine the correct fuel type and octane rating.
- Filling the tank: Park the equipment using the fuel away from any ignition sources. Slowly pour the fuel into the tank, leaving some space at the top to allow for fuel expansion. Do not overfill the tank. After filling, tighten the fuel cap securely.
- Handling and transportation: When carrying the portable fuel tank, hold it upright and avoid any sudden movements or impacts. Use a trolley or carrier designed for fuel tanks if possible. During transportation in a vehicle, secure the tank in an upright position and ensure it does not move around.
- Storage: Store the portable fuel tank in a well - ventilated area, away from heat, direct sunlight, and flammable materials. Keep it out of the reach of children and pets. If storing for an extended period, consider using a fuel stabilizer to prevent fuel degradation.
- Fuel transfer: When transferring fuel from the portable tank to the equipment, use a proper fuel - transfer pump or funnel to avoid spills. Make sure the equipment is turned off and cooled down before refueling.
- Cleaning and maintenance: Regularly clean the exterior of the tank to remove dirt and debris. Inspect the tank and its components, such as seals and valves, for wear and tear. Replace any damaged parts promptly.

Safety precautions: Always wear appropriate personal protective equipment, such as gloves and safety glasses, when handling fuel. Do not smoke or use any open flames near the fuel tank. In case of a fuel spill, clean it up immediately using an absorbent material and dispose of it properly.
