Note: DO NOT run the pump in reverse. Drill is not included! Description: Designed to work with a corded or cordless drill, which can convert most drill into a high capacity pump capable of emptying sinks, aquariums, pool skimmers and much more. Features: Designed to work with a corded or cordless drill, fits for most electric drills. Small size, lightweight and portable, convenient installation. Suitable for home, garden, and outdoor. Ideal for transferring light liquids, such as freshwater, seawater, oil, dilute organic solvents, insecticides, and liquid fertilizers. Engineering plastic body and stainless steel internal parts to avoid corrosion. Specifications: Material: Engineering Plastic Color: Black Size(LxWxH): approx. 10.5 x 3.7 x 6.4cm Applicable Diameter of Tube: 1.6cm Working Temperature: 5-49 Degrees Celsius Rotating Speed: Suggest 1500-3500RPM(1500:Flow Rate: 15L/Min; 3000:Flow Rate: 30L/Min) Operation Instruction To ensure optimum priming and long life, apply a few drops of lubricating oil in the pump inlet prior to each use and flush with clean water after each use. Be sure the inlet hose is airtight and as short as possible. The inlet hose should not exceed 9ft (2.75M). When pumping abrasive fluids or liquids with solids, longer pump life will be obtained by using a strainer on the inlet line. It is recommended that the pump is mounted to a surface for security and ease of use. Mount and start the drill. Watch inlet tubing to be certain fluid is drawn into the pump in 15-20 seconds. If not, check that the inlet tube is properly mounted to the inlet. Do not run dry. If the pump fails to prime, check to be sure that the hoses are not Kinked or clogged. The pump depends on the fluid being pumped for lubrication.
