3. Add water.
・For dry clay:
If not enough water is added, this can casue the unit
to overload, and result in the auger screw to stop. If
too much water is used, the clay will become too soft,
preventing the clay from being mixed and extruded. Add
water a little at a time so that there is no puddling, but
the clay has a workable moisture.
・For leather hard clay:
If too much water is added, the clay will become too
soft, preventing the clay from being mixed and extruded.
Add just enough water to resaturate the clay.
Note)
Do not operate the vacuum pump until the clay has the
proper amount of water. Powdered components may clog
the vacuum chamber if the vacuum is turned on too soon.
4. Close the hopper cover.
• Close the hopper cover. If there clay on either rim
surface of the case or hopper cover, wipe it off. both
surfaces must be clean to create a good seal.
Push down on the handle so the hopper cover can
properly lock into the case.
5. Mixing process
① Turn ON the power switch and close the vacuum
pressure relief valve.
② Turn ON the vacuum pump switch and check the
readings on the vacuum gauge.
③ Set the selector switch to MIX when the gauge
reaches 0.09 Mpa.
④ Slowly turn the screw speed control to between 6 and 8.
• If there is not enough clay in the hopper, stop the auger
screw and add more clay and water. To stop the auger,
return the speed control to 0, set the selector to STOP,
then turn OFF the power switch.
• Continue mixing for a while. If the electric current of the
motor exceeds 3.0 A, add water. If no water is added, an
overload may occur, causing the auger screw to stop.
Note)
Do not set the speed control between 0 to 3.5.
If the auger screw is turns at too low a speed, too much current
will flow to the motor, triggering the auger screw to stop.
Note)
The hopper cover has a limit switch sensor that detects
when the cover is open or closed. If too much vibration is
generated due to too large of clay chunks, the limit switch
sensor may be triggered, causing the screw to stop.
If the limit switch sensor gets trigger too frequently, the
motor may shut down due to overload.
Add an appropriate amount of water.
Push down on the handle
so the hopper cover can
properly lock into the case.
Warning
Do not access any switch with wet hand.
③ Set the selector

power switch
Note)
The auger screw automatically stops after 2 hours of
continuous running*, and "END" will appear in the indicator
box. Should this occur, return the selector switch back to
"STOP" to restart operation. As the clay keeps being mixed,
the clay and the barrel will heat up due to friction. Therefore,
if operating continuously for more than 2 hours is necessary,
open the hopper cover and allow time for cooling. When de-
airing, the internal pressure increases due to frictional heat;
wet clay may splash from the gap between the extruding slot
and the hopper cover.
* When the selector switch is returned to "STOP" once or the
limit switch sensor activates, the timer is reset.
