8. Before opening the door, ensure for safety that there is nothing in the door's way.
9. Do not leave the door of the furnace open when the machine is not used.
10. Always keep clean inside of the furnace. Investment residue or dusts on the turntable or the
wax drain orifice etc. may cause clogging and prevent wax from draining out of the furnace. As a
result, a large amount of incomplete combustion gas is discharged.
11. Do not pile up flasks. If flasks fall down, the inner wall of the furnace may be damaged.
Further, if they come into contact with the heater wires, an accident such as short-circuit may be
caused.
CAUTION
1. Periodically, check and clean the rotation driving parts. Remove wax on the bearing system.
2. Do not try to cool inside of the furnace forcibly and very rapidly using a fan. Particularly,
if forced cooling is done when the machine is heated to high temperature, the door frame
material may be cracked or deformed.
3. When burning out a large number of flasks in one batch, take ample time for each step of
burnout cycle.
4. Always use the wax collection container. A deep container is recommended because drained
wax will not splash around.
5. If you operate burnout of stone-set flasks, be sure to check that the overheat protection key
switch is turned to on, check the set temperature limit value of overheat protection device
beforehand, and change the set value if necessary to proper value.
