heat expansion. Especially, in case of using used alloy, take care of alloy heat expansion.
Close and lock the chamber lid.③
Press the “Standby” button to vacuum and increase the temperature inside of the chamber.④
Check the melting condition visually from the window of lid and wait until the melting alloy become mass.
Note) Use a shaded protective glass to protect your eyes in case of high temperature.
After the melting alloy become mass, press the “Retention” button to hold the temperature.⑤
Unlock the chamber lid with this condition and vacuum will be automatically released wait 5 seconds to⑥ (
open the door . After the release of vacuum, place a burned-out casting ring. If the button is not at the)
center, adjust the space so that the casting ring is set properly and fit the melting alloy outlet.

Other Operations■
Chamber Position Adjustment●
Muffle rotation and its position could slightly move after many years of usage.
In this case, adjust the muffle rotation and its position by the following.
Keep pressing the button and press the “Finish” button during the standby mode after power on. L, M▲
and H lamp of “Vacuum”, lamps of “Stand by”, “Retention”, “Final” and “Casting” illuminate and “Finish”
lamp blinks.
1. Lock the chamber lid and press the “Argon” button so that its lamp illuminates and the muffle chamber
inverts.
2. Press the “ ”” ” buttons to adjust the casting position (inverting position). When the rotation is too▲▼
far, subtract the casting position value.
3. Press the “Pressure Timing” button so that the lamps of L, M and H go out and lamps of 1, 2 and 3
illuminate.
4. Press the “ ”” ” buttons to adjust the melting position (original position) in the same way as the▲▼
casting position.
5. Press the “Vacuum” button to adjust the casting chamber position again. After some adjustments of the
casting chamber position and melting chamber position, press the “Vacuum” button to finish the adjustment.
If you do not press the “Finish” button, the adjustment will not be saved.※
Note) If the unit continues the operation 50 times, “ERROR” lamp blinks and the unit stops inverting. Press the “Argon” button to※
adjust their positions again.
Air/Argon Switch Knob◎
The knob is equipped at right side of the unit. You can choose air pressure or argon gas pressure.
Argon gas pressure is useful to minimize oxidation of melting alloy.
In case of using argon gas pressure, use a regulator to set pressure between 0.5 and 0.9MPa.※
Note) Perform the casting operation without melting of the alloy to exhaust gas because it will be mixed in the first pressure after※
the pressure type is switched.

-13-
Periodic Machine Cleaning■
In order to maintain the capacity of this unit further longer the following periodic cleanings prior to use are
recommended.
Note) When you perform machine maintenance, make sure that the unit is turned off and the muffle heat is as low as room temperature
to prevent the cause of skin burn and electric shock.
Muffle Cleaning●
When the chamber turns upside down for casting operation, metal debris, etc. in the muffle may result in
miscasting. We recommend you to use the dust collector provided referring to the following recommendations.
Figure 1. Open the chamber lid and lift the knob ( ). Move the knob in the direction of to unlock.①②
Figure 2. Lift the tab to remove the casting ring stand.
Figure 3. Take out the dust collector on the bottom to clean the dust. In reverse order, place the dust collector
and the casting ring stand back to its original position.

Drain Filter Check●
See the drain window equipped on the left of the unit to check the moisture in the air tank.
Loosen the drain cock equipped on the backside of the unit to drain the moisture in the air tank.
Loosen the drain cock gently to prevent the moisture from shooting. Use a waste pan to catch the moisture.
Ifyouusetheunitwithmoisturecollectedovertheallowable level, the moisture will come in contact with
inside of the unit and cause machine malfunction.
Dust Proof Filter Cleaning●
If you use the unit with the clogged filter, the cooling fan will not work properly and cause overheating of
the parts and machine malfunction. Remove the filter that is located on the bottom of the unit to clean the
dust with an air gun.
Compressed Air Filter Check●
(← )Press the button at the bottom of compressed air filter marked on the right
to drain the moisture gathered inside the compressed air filter. We recommend you
to drain the moisture each time before using the unit, regardless of the amount of
moisture collected. If you use the unit with the moisture collected over the allowable
level, the moisture will come in contact inside the unit to cause machine malfunction
when you apply pressure.
