Specifications

Setup

The SMACO High Pressure Hand Pump is designed for easy assembly. Follow these general steps to set up your pump:

1. Unpack Components: Carefully remove all parts from the packaging and verify against the "Package Contents" list.
2. Assemble Pump Body: Connect the handle to the pump body and secure it.
3. Attach Foot Pedal: The foldable foot pedal is typically integrated or easily attached to the base of the pump. Ensure it is securely in place and can be folded out for stability during use.
4. Connect Pressure Gauge: Attach the pressure gauge to its designated port on the pump body.
5. Connect High Pressure Pipe: Securely connect one end of the high pressure pipe to the pump's output port.
6. Install Oil-Water Separator: Attach the oil-water separator to the other end of the high pressure pipe. Ensure all connections are tight to prevent leaks.
7. Initial Check: Before first use, perform a visual inspection to ensure all connections are secure and there are no visible damages.

Operating Instructions

Follow these steps to safely inflate your diving oxygen cylinder using the SMACO High Pressure Hand Pump:

1. Prepare the Pump: Open the folding base of the pump to ensure stability during operation.
2. Connect to Scuba Tank: Connect the 8mm female connector of the high pressure pipe (with the oil-water separator) to the valve of your scuba tank. Ensure the connection is firm and secure.
3. Close Pressure Relief Valve: Locate the pressure relief valve on the pump and ensure it is fully closed before starting inflation.
4. Begin Inflation: Start pumping the handle up and down. Monitor the pressure gauge closely.
5. Stop Inflation: Continue pumping until the air pressure in the scuba tank reaches 3000 psi or 200 bar (indicated by the red line on the pressure gauge). Immediately stop pumping once this pressure is reached.
6. Relieve Pressure: IMPORTANT: After completing inflation, slowly open the pressure relief valve to release any residual pressure in the pump and hose. Failure to do so can be dangerous.
7. Disconnect Scuba Tank: Once the pressure is relieved, carefully pull out the scuba tank from the pump connection. The inflation process is now complete.

Safety Notes:

• Always relieve pressure using the pressure relief valve after inflation.
• Do not exceed the maximum recommended pressure of 3000 psi / 200 bar for the scuba tank.
• Ensure all connections are tight before and during inflation.

Maintenance

Regular maintenance ensures the longevity and safe operation of your SMACO High Pressure Hand Pump.

• Oil-Water Separator: The pump is equipped with an oil-water separator that uses coconut shell activated carbon and cotton core double filtration to purify the air. The filter element should be inspected periodically and replaced when it appears dirty or when air purification efficiency decreases.
• General Cleaning: Keep the pump clean and free from dirt, dust, and moisture. Wipe down the exterior with a damp cloth after use.
• Storage: Store the pump in a dry, cool place, away from direct sunlight and extreme temperatures. The foldable foot pedal allows for compact storage.
• Inspection: Periodically inspect the high pressure pipe for any signs of wear, cracks, or damage. Replace if necessary. Check all connections for tightness.

Troubleshooting

This section addresses common issues you might encounter with your hand pump. If you experience problems not covered here, please contact customer support.

• Difficulty Pumping / No Pressure Build-up:
  • Ensure the pressure relief valve is fully closed.
  • Check all connections for leaks. Tighten any loose fittings.
  • Inspect the high pressure pipe for damage or blockages.
  • The internal seals might be worn. Contact support for service.
• Air Leaks:
  • Check all threaded connections (pump to hose, hose to tank, oil-water separator). Tighten them using the provided wrench if necessary.
  • Inspect O-rings and seals for damage or improper seating. Replace if worn.
• Excessive Effort Required to Pump:
  • This is a high-pressure pump; significant effort is normal, especially as pressure increases.
  • Ensure the pump is well-lubricated (if applicable, refer to specific lubrication instructions not provided in source data).
  • Take breaks during pumping to manage effort.

User Tips

• Pumping Time: Inflating a 1-liter scuba tank manually can take a considerable amount of time, potentially around 1 hour with necessary breaks, depending on your physical condition and the desired pressure. Plan accordingly.
• Breaks are Key: For optimal performance and to prevent overheating of the pump (and yourself!), take regular breaks during the inflation process.
• Monitor Pressure: Always keep a close eye on the pressure gauge. Over-inflating can be dangerous.
• Portability: The pump's design allows for easy disassembly and portability. When traveling, separate the bottle head and body of your mini scuba tank if carrying it on board.
