To ensure optimum priming and long life, apply a few drops of lubricating oil in pump inlet prior to each use and flush with clean water after each use. – 2. Be sure inlet hose is airtight and as short as possible. Inlet hose should not exceed 9ft (2.75M). – 3. When pumping abrasive fluids or liquids with solids, longer pump life will be obtained by using a strainer on the inlet line.- 4. It is recommended that the pump is mounted to a surface for security and ease of use. – 5. Mount and start drill. Watch inlet tubing to be certain fluid is drawn into pump in15-20 seconds. If not, check that inlet tube is properly mounted to inlet. – 6. Do not run dry. If pump fails to prime, check to be sure that hoses are not Kinked or clogged. Pump depends on fluid being pumped for lubrication. Note: DO NOT run pump in reverse. Package – 1 x Drill pump – 2 x Hose clamps- 2 x Connectors
