Installing the Pump.
a. Assembling Pump, Motor, and Drop Hose.
(1)
Check to see that the drop hose end is cut square. Use a sharp knife or hacksaw to cut the hose. Then
install the hose coupling into the end of the drop hose (see figure 2-48). If insertion is difficult, cut a 1/2" slit
in the end of the hose. This will help you start the coupling into the hose.
NOTE
Do not use any form of lubrication on the hose or the coupling.
(2)
Push the hose fully onto the shank of the coupling. The end of the coupling may be tapped lightly on a
wood surface, if necessary.
(3)
Cut away about six inches of the cable ridge from the hose. Use a file to smooth the ridge even with the
outer hose surface.
