NOTE!
DO NOT PUT YOU
R
HANDS INTO THE
VALVE HOUSING AT ANY TIME (
F
i
gu
re
37)!
Spray water into the opening, washing the end of the
rubber ram, the material cylinder, the rock valve and
the outlet pipe. Continue washing until the water that
leaves the valve is clear and clean. Visually inspect that
no rocks, sand or clumps of concrete remain. If there is
still material, continue spraying (Figure 38).
Be sure that your rake, and everything else is out of the
valve area, then cycle the machine in reverse for one
more stroke. This will expose the opposite material
cylinder, and completely extend its rubber ram. Pull
any loose material out with the clean-out rake, then
spray out the material cylinder as in the previous step.
By putting the pump in the “REVERSE” mode, you are
sucking from the pipeline (which is not connected
during the clean-out procedure) and pumping into the
hopper. Because of this, you may find that you now
have some material in the bottom of the hopper again.
You should now wash this material out.
Spray off the clamps, gaskets and wedges.
Close the hopper clean-out door, and reattach the
bungy cord, if used.
Be careful with acid
Many aggressive cleaning compounds can do damage
to chrome and rubber seals. Always follow directions
very carefully when using such cleansers.
