Frequently Asked Questions (FAQs)

Operation & Performance

• Do I need to prime the pump before every use?
  Yes. You must fill the pump casing with water through the top priming plug before starting the engine. Running the pump dry will destroy the internal mechanical seals. 
• What type of water can this pump handle?
  This is a clean water pump. It can handle small particles up to 9mm, but it is not built for thick mud, heavy sewage, or trash. For those tasks, a dedicated trash pump is required. 
• How can I maximize the water flow rate?
  Place the pump as close to the water level as possible to reduce the suction lift. Keep the suction and discharge hoses short and straight. 

Fuel & Maintenance

• What fuel type does the engine use?
  The pump requires straight unleaded petrol. Do not use stale or contaminated fuel, and never mix oil directly with petrol into the tank, as it features a separate 4-stroke oil sump. 
• How do I store the pump long-term?
  Drain all fuel from the tank and the carburetor bowl to prevent stale gas from clogging the engine components. Flush clean water through the pump casing to clear out any remaining sediment or debris. 
• Can I run this machine indoors?
  No. Petrol engines emit dangerous carbon monoxide gas. Only operate the unit outdoors in well-ventilated spaces. 

Troubleshooting

• Why is the pump running but not moving any water?
  Check for air leaks in the suction hose connections or a damaged sealing washer, as even a tiny air leak stops a vacuum from forming. Also, confirm that the suction strainer is completely submerged and clear of debris. 
• What should I do if the engine won't start?
  Verify that the engine switch is set to 'ON', the fuel valve is open, and the choke lever is closed for a cold start. Check that the engine oil level is full, as many modern small engines have low-oil shutdown sensors.
