Housed within a rugged open frame, with a convenient carry handle, it's easy to move and store but this frame also provides protection from potential damage to the pump and engine itself.

Before using your pump, make sure you have your suction hose and layflat hose ready. The suction hose is used between the water source you are looking to move and the pump, and is more sturdy and strengthened to stop it being ‘sucked’ flat while in use. The layflat hose is used on the outlet of the pump and usually sits ‘flat’ - hence the name. Try to use the minimum amount of suction hose possible and place the pump as close to the water as you can.

Simply attach the strainer (the plastic ‘cage’ included with the pump), to the end of the suction hose, which prevents debris being sucked into the pump and causing damage to the impeller. Then, using the provided collars, attach the other end of the suction hose to the inlet on the pump. Use the other collar to attach your layflat hose and run it to then are you want the water to be discharged to.

This pump is self priming, however in order to create a vacuum and start the lifting process you need to fill the pump housing with water. You can do this by removing the  the cap on the top of the pump casing and filling with fresh water, then simply follow the starting procedure in the manual to begin pumping. Ensure that there are no air leaks on the suction side, as this will prevent the pump from priming.
