Main connection
Connect the BIOSTARØ machine to 100/115/230-V-network by plugging in the original power cable on the back of the
machine O, two fuses are buitt in to protect the machine from high voltage. TO exchange the fuses please press the little
cip below the connector O and take out the fuse.
Compressed air connection
A 20 bar tube O with filter elementis fixed to the back of the machine and should not be exchanged. Connect the BIOSTAR"
machine to the air pressure system, use the 20 bar tube and optionally a quick connect coupling. The working pressure is
set up at 6 bar/87 psi and should not be changed as it is calibrated to achieve the best pressure moulding results. The
active pressure is permanently shovvn in the display. However, if you wish to lower the working pressure, just adjust it by
using the pressure regulator O on the back Ofthe machine. Before turning the regulator, pull to release it. Adjust the pressure
byturning the regulator ( _nc andpushit in afterwards. I f the pressure exceeds6,5 bar/94psi the securityvalvewillbe
set into action.

Positioning of blanks
All round blanks and foils with a diameter Of 125 mm and a thickness OfO,1 to 5 mm can be pressed in the BIOSTAR'.
Open the pressure chamber O by swivelling on the left side. take off the locking ring O by turning it in 5 0'clock position,
place the foil or blank directly on the O-ring, Put on the locking ring, so that the bayonet clamps slip under the bevel of the
locking device of the chamber. Tighten by turning clockwise into 6 0'clock position.
Model preparation
Whenworking with hard or hard elastic foils, the rnodels are placed into the model cup O which is completely filled with
stainlesssteel pellets. When working with soft elastic foils, the models can be placed on the model platform O. In both
cases, the model should be placed with the incisors facing towards the locking handle O to ensure equal thickness of the
foil or blank between the quadrants.
Programming
Our pressure moulding materials have a 3 digit code in which all necessary information on temperature,
cooling time is programmed. Choose your material. press the button "code", program the digits and confirm by pressing
the button "code" again
Heating
After programming, directly swivel the infrared heater O over the foil. The temperature is regulated automatically by a therrno
element.The colour of the heater might vary from bright to dark.
Pressurizing
Before the end of the heating cycle is reached, an audible beeping sound is heard which lasts for five seconds. After five
seconds. a continuous beeping sound is heard for a further five seconds with the dernand for closing the pressure chamber
O With the locking handle O. During these five seconds the infrared heater iS returned to its rest positon. The pressure
chamber is brought over the model and locked into place by turning the locking handle 1800 degrees. Automatically the
magnetic valve opens, the pressure chamber fills with air and the moulding process begins. You will notice that the cooling
time begins as indicated on the display, You may experience some air leakage when working with thin foils, this is normal
and will not affect the final result of the moulding. If the pressure moulding is not started within ten seconds, the infrared
heater will switch Off and the whole process has to be started again with a new foil. Remember also to reprogram the
BIOSTAR" with the correct code,
Depressurizing
After cooling time has elapsed, press the button •air" and after another 3 seconds the locking handle O and the locking
ring O can be opened. After this, the pressure chamber O is swivelled to the left hand side, so that the model remains in
the pellets or on the model platform.
Maintenance
The BIOSTAR*machineis maintenancefree. However, the air tube includingthe fitter element should be examined regularty.
If moisture or debris is released, the filter must be replaced. The model cup O with air holes and model platform O can be
cleanedwith an air gun. The reflectingpart of the pressure chamber should be cleaned regularlyto obtain the best heating
results. Forcleaning remove the aluminium adjusting ring@from the pressure chamber O completely. This will allow you
to lightly grease the sealing surfaces. The sealing ring and the four trivets and springs should be cleaned and fightly greased
also. Placethe adjusting ring back on the trivets and springs ensuring that the sealing ring cornes to the top and that the
whole unit is movable.
