*At any time physical contact must be made with the pump, motor, wire, etc. caution should be taken to kill the power by turning the main power disconnect to the OFF position.*

1. Visually inspect the pump and floats.
2. Make sure the screen and impeller veins are clean and free of debris. 
3. Check the screen mesh for any tears, make sure the sides, bottom, and top are all securely attached. – ALWAYS USE A SCREEN – THIS IS THE PUMP’S ONLY PROTECTION.
4. Thoroughly examine the floats, make sure there are no leaks or visible problems and that they are attached correctly and any un-used bolt holes are plugged.
5. Make sure the pump turns free and is not locked down.  (If the pump is locked down and you turn it on, it will not be able to spin and will result in burning the motor.)
6. Grease the top and bottom bearings on the motor if needed.  Make sure you are using the correct grease and the proper amounts.  On one side of the motor you will find a grease zerk on the top and bottom.  On the opposite side of the motor from each grease zerk, there will be a relief plug.  Remove these two plugs and fill both cavities until grease begins to come out of the unplugged holes.  Some of the motors will have the top and bottom relief plugs exposed, while others will have the top relief plug covered by the fan shroud.  It will be necessary to remove this shroud in order to remove the relief plug and fill the cavity with the correct amount of grease.  When you are finished replace the plugs and fan shroud.
7. Inspect the discharge hose for any holes and make sure it is properly clamped on the pump discharge and the bank.
8. Inspect your electrical cord to make sure there are no breaks in it and that it is properly connected and no wires are loose.
9. When you are ready to start the pump, make sure it is floating at the correct level, water should cover about the bottom ½ of the discharge pipe.
10. Start the pump and listen for any unusual sounds.  If it sounds rough your bearings may need to be greased or replaced.
11. Make sure the air relief tube is shooting a steady stream of water to the rear of the pump, down and away from the motor, without excessive splash.  If not, remove the air relief tube and fitting from the pump and clean them.
12. Make sure the pump is rotating the right direction.  5-30HP 3600RPM motors should be turning counter clockwise.  All 1800 RPM pumps should be turning clockwise as well as our 30-75HP high pressure pumps.
13. Make sure the flow and amperage are within a normal operating range for your pump.  If you keep a log of this at regular intervals it will help you be able to recognize if any problems arise.
14. If you see visible water shooting towards the motor; that is an indication that you have a great deal of wear and your pump is in need of repair.
