Professional Grade Gas Water Pump - 7.5HP 3600RPM, 1236ft³/h Capacity for Irrigation/Construction Sites

Notes 1. Please read the operating manual completely before use. And pay particular attention to the safety instructions included. 2. The first use of the break-in period is 5-10 hours, and the engine oil needs to be changed, otherwise, impurities in the engine oil during the break-in period will jam the crankshaft. 3. Add gasoline of 90 # or above to the fuel tank of a four-stroke gasoline engine, and add engine oil to the casing. Please check the engine oil level before each use. 4. When working continuously, the temperature of the crankcase should not exceed 194℉. If it overheats, the machine should be stopped for 15-20 minutes before continuing to work. When adding gasoline, it must wait for the machine to cool down before proceeding. 5. It is prohibited to stop the machine at high speeds. The machine should be stopped when the throttle is lowered to the lowest! Please use clean and impurity-free engine oil. 6. The air filter cartridge should be regularly inspected and replaced. If it is dirty, clean it with soapy water and let it dry before use. The machine is not in use for a long time. Please do not directly turn off the gasoline engine switch. Instead, turn off the throttle switch to consume all the gasoline in the carburetor. If there is oil in the carburetor that is not consumed for a long time, it will cause oxidation of the carburetor. The spark plug generally does not need to be replaced. Once carbon deposits, they can be removed and scraped off with a knife. 7. Before using this gasoline engine water pump, please add water through the inlet to submerge the impeller and ensure that it is not used in water. 8. We recommend using unleaded gasoline for optimal performance.
