For optimal priming and a long service life, apply a small amount of lubricating oil to the pump inlet before use and rinse with water after each use. 2. Ensure the inlet hose is leak-proof and as short as possible. The inlet hose should not exceed 9 feet (2.75 m). 3. When pumping abrasive fluids or liquids containing solids, please attach a strainer to the inlet to extend the pump's lifespan. 4. It is recommended to mount the pump on a surface for safety and ease of use. 5. Mount and start the drill. Monitor the inlet tubing to ensure fluid is drawn into the pump within 15 to 20 seconds. If not, check that the inlet tube is properly attached. 6. Do not run dry. If the pump does not prime, ensure that the hoses are not kinked or obstructed. 7. It is recommended to set the rotation speed between 1500 rpm and 3000 rpm. The faster the speed, the greater the lift and flow rate.
