6.3 Adjustments During the
Mixing Process
• Youcanchangethemixingtimeand
speed while the device is operating
(Fig.15/16).
• Themixingtimeyousetbeforestarting
the process is saved.
• Ifyouchangethemixingtimeduring the
process, the new time will not be saved.
Tip:
Only mix the same type of material
in a given bowl. Residue form pre-
vious mixing processes can have a
negative inuence (e.g., silicon fails to
harden, etc.).
We recommend a separate bowl for
each type of material (plaster, invest-
ment, silicon).
7. Cleaning / Maintenance

You should regularly coat the rubber
seals with Vaseline. This will signi-
cantly increase their service life and
optimize to unit’s function
