1. Close the hopper cover.
2. Open the pressure relief valve.
3. Check that the power switch is OFF.
4. Check that the selector switch is set to STOP.
5. Check that the vacuum pump switch is OFF.
6. Check that the power cord is unplugged.
7. Check that the auger screw xing bolts are securely
tightened.
* Be sure to check each time before use. If the screw
becomes detached, the unit could become damaged.
Possible unintended issues while operating:
• If the power cord and the limit switch sensor are
damaged, there is the potential danger of electric shock
and/or short circuit.
• The limit switch sensor and its cord are damaged, as
such, “the screw does not rotating” or “the auger screw
does not rotate”, regardless of opening/closing the door.
• If the internal circuits are damaged, “the direction of
rotation could not be switched” or “the rotating speed
could not be adjusted”.
If these issues arise while operating, stop using the unit
and contact your dealer or our o󰀩ce.
Do not operate any switches with wet hands.
Warning
1. Supply clay.
• About 18 kg (45lbs) of clay can be mixed at one time. If
there is not enough clay in the barrel, it will take longer
for the clay to be mixed, or there will not be enough clay
in the barrel to be extruded. It is necessary to ll the
barrel to the appropriate level when processing dried clay.
• If the clay is in large clumps, break them down to an
appropriate size rst. Very wet clay cannot be recycled
by itself. To recycle really wet clay, either dry it out
some, rst then recycle it or add dry clay to the mixture.
2. Feed clay.
• Do not add too much clay into the hopper at once,
otherwise the hopper cover may not shut. Add enough
clay to see the top of the auger screw.
While mixing, more room may be created as the mixture
compacts, After a short mixing time, add additional clay
to ll back up to the top of the auger screw.
Make it smaller than your st.
Feed clay to a level that allows
you to view the top of the screw.
