Operation procedure
3. Add water.
• Add an appropriate amount of water.
• If the amount of water is not enough, an overload may
occur, causing the auger screw to stop. If the amount
of water is too much, the clay will become too soft,
preventing the clay from being mixed and extruded.
If you do not know how much water to add, add
water in gradually while keeping note.
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
Turn ON the power switch and set the selector switch to
MIX. Slowly turn the screw speed control to select 6 to 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.
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.
Set the selector
① ‌ ‌ T urn ON the
switch to MIX
power switch
Note)
The auger screw automatically stops after 2 hours of
continuous running, to prevent the mixed clay from
generating too much heat.
When the auger screw is stopped by the timer, "END"
will appear in the indicator box. Should this occur,
return the selector switch back to "STOP" to restart
the operation.
