Clean-Up
After operation has been completed for the day, the following procedure should be used to clean the
machine and material hose.
Throughout the day, the machine operator should have sufficient time to keep the exterior and interior of
the machine washed clear of any excessive build-up of material caused by spillage or ingredient addition
during the mixing operation. A wash-down hose and spray nozzle are a part of the supplied water system.
This hose should be used to keep the exterior and interior of the machine clean and for machine cleanup
at the end of the day.
Danger:
This machine should never be operated or sprayed with water without sealing the electrical
disconnect box. The metal key supplied with the machine should always be used to lock and seal the
machine’s electrical disconnect box before clean up begins. Rotating the lock counter-clockwise, by use
of this key will seal the box and prevent water from contacting electrical components inside the box.

Machine Clean-Up
In order to maximize the amount of material put in place, the machine operator should run water
into the mixer and start cleanup immediately after last batch is mixed and discharged into the
pump hopper. Continue pumping until wet material is being discharged at end of hose.
With mixer discharge door closed and paddles turning, fill the mixer about 1/3 full of water. At
the same time, spray water through mixer grate onto any material buildup inside. DO NOT
REMOVE MIXER GRATE WITH MACHINE RUNNING. Wash as much material buildup as
possible from inside the mixer and paddles with water from wash-down hose. Let mixer run at
least two minutes with water in mixer, or until material level in hopper is low enough to see
agitator blade. Continue pumping and discharging water into hopper.
The hose operator should continue until materials become too wet to use. The machine operator
should warn hose operator when water is being pumped. This alerts the hose operator to watch
for wet materials.
The mixer operator should pump remaining water out of hopper through hose until approximately
one inch of the agitator blade is visible. With hopper almost empty, place all controls in “OFF”
