Step 5. Unreel the needed length of the selected discharge hose(s) from the reel to the desired length.
NOTE: Each discharge hose will require an operator. Another operator will be required to match the
Step 6. Open the bull valve by turning the handle counterclockwise (Figure 30).
Step 7. Open the slurry nozzle by turning the knurled portion of the slurry nozzle until you get the spray
pattern you want. Turn the slurry nozzle clockwise for a fine spray. Turn the slurry nozzle
counterclockwise for a more solid stream of water.
When the preceding actions have been performed, use the apparatus to spray equipment or vehicles as
required. After you finish spraying, close the ball valve of the gun assembly by turning it clockwise.
Shut down the pump unit as described in Lesson 2, Learning Event 2. Drain the apparatus. Reopen the
ball valve of the gun assembly to drain the discharge hose. Drain the pump by opening the pump drain
When the pump is entirely drained, replace the hoses and equipment as follows:
Step 1. Open the toolbox on the pump unit and take out the crank handle. Put the crank handle into the
center of the hose reel. Turn the crank handle counterclockwise to rewind the discharge hose onto the
hose reel. You should have an assistant to guide the hose onto the reel neatly. Close the gun assembly
valves. Rotate the slurry nozzle assembly closed to prevent damage. Then stow the fun assemblies on
their brackets. Close valves 1, 2, 3, and 4. Return the crank handle to the toolbox.
Step 2. Remove the foot valve end suction hose from the natural water source. Take the submerged
container out of the water. Disconnect the foot valve from the suction hose and attach the foot valve to
the tank unit bracket.
Step 3. Remove the suction hose from the pump unit, straighten it out, and place the blender hose inside
it. Secure these two hoses on top of the tank unit.
Step 4. Replace the caps on the pump suction hose connector and the foot valve.
