PREVENTING DAMAGE TO EQUIPMENT
The following recommendations will help avoid damage to your equipment:
 Always use the proper fuel mixture.
 Do not run the engine at full speed until thoroughly warmed up.
 Do not lift strainer out of the water while pump is operating.
 Do not run engine with pump disconnected.
 Do not run the pump when dry.
 Always draft water using a footvalve suction hose strainer.
 Check strainer frequently to make sure that it is not clogged with moss, leaves, etc.
 Flush the pump with fresh water if the pump has been used to pump salty, brackish,
high mineral content water, water containing debris, or foam injected water. Check that
debris is cleared before using pump again.
 Drain pump after final use.
 During freezing weather, drain the pump and lines of all water. You can also pour some
antifreeze into the pump and circulate it through the pump and plumbing system.
 Pumps should not be operated without water for any extended period of time or without
discharging water. Operating the pump in such a manner can overheat the pump
causing damage to seals, or pump internals.
 It is recommended that all fasteners be replaced with genuine WATERAX parts.
