• Put a couple of shovelfuls of sand or dirt in the
bottom of the rock valve housing, above the
clean-out door. This will prevent concrete from
filling the door area and setting during the
course of the day. (Figure 25).
• Be sure the clean-out door is closed tightly and
locked by tapping on the end of the “T” handle
with your hammer (Figure 26).
• If you will be using portland cement and water
to make your lubricating slurry, prepare for it
now (Figure 27). Position your barrel, shovel,
and sack of portland cement on the ground
behind your hopper. Fill your barrel with about
25 or 30 gallons of water. (Of course, this step
can be skipped if slurry is to be delivered to
you from the ready mix company, or if you are
using powdered slurry mix.)
• Get your clean-out rake in a position that you
will not trip on it, but you will be able to grab it
when you begin clean-out. Many times,
cleaning the pump is done when you are in a
hurry, because concrete is setting, that is no
time to have to look for the rake or, worse yet,
to use your hands to pull loose material out of
the pump because you don’t have time to look
for it.
