7.3 Operation

Manual mode
(Start menu)
Menu After selecting the menu item 'Manual mode' [yellow keys (11/12)]
and confirming with Enter, a cartridge which had been accidentally
Menu
inserted can be ejected using the blue Manual mode key (08). The
piston will move back after approx. 6 seconds.
Enter
Attention: Do not inject any objects using the manual mode. The
parameters of the individual materials will not be adopted in this
mode. Manual mode is only intended for cleaning or individual car-
tridge ejection.
Selecting a language
(Start menu)
The menu-guidance is factory preset to the English language.
CE key
The CE key (15) is used to abort any process and to complete storage
CE
of data. Regardless of any occurring malfunction, the piston will
always return to its initial position.
Parallel mode
Parallel operation of both heating chambers is possible.
It must be ensured that there is sufficient time (approx. 5 minutes)
between the starts of the two programs to avoid overheating of the
material.
Attention! In the parallel mode only materials with identical melting
temperatures can be processed. Proceed like in the single operation
mode; move the heating cylinder lever (17) and press the cor-
res-ponding heating time keys (05/07).
Buzzer key
The buzzer is deactivated after pressing the buzzer key. The program
sequence will not be discontinued.
Button - Previous program
If several objects are injected using the same material, the same pro-
gram is started with the Previous program (04) key without selecting
Program
the individual steps 02-05.
Program changes and accompanying temperature changes result in a
cooling phase or heating phase displayed correspondingly.

8. Care and maintenance

Aluminium residues of the cartridges, burnt-in silicone grease or other mate-
rial residues must be removed from the heating chambers of the unit within
regular intervals These residues may become stuck between the piston tip and
the wall of the cylinder and thus affect the casting result. If Bio XS is used,
the unit should be cleaned before and after each injection process due to the
low melting temperature of aluminium and other residues.
Do not use objects with sharp edges for cleaning. Select Manual mode
Enter
in the main menu, confirm by pressing Enter (16) once and then move
the piston several times using the Piston forward (08) and Piston
backward (06) keys until the aluminium residues are removed. Use
an extraction system or a suitable cloth to remove the residues. Fine
residual particles can be removed with the special thermopress metal
cleaning brush (accessories -
Note: Cartridges containing a different material composition may dam-
age (scratches) the polished inner wall of the cylinder. This will affect the
injection performance of the unit considerably. In order not to damage the
polished inner cylinder, exclusively use the metal cleaning brush available
from bredent.

8.1 Lubricant

thermopaste 400 ( 540 0105 1) must be used for all materials;
silicone paste will be burned at such temperatures.
Spread a small quantity (size of a pea) evenly to the cartridge wall.
Do not apply any lubricant in the area of the cartridge lid to avoid
contaminating the resin.
Note: Other lubricants will be burned and lead to poor injection
results.

8.2 Microfuse

The unit fuse holder can be accessed from the exterior. The fuse holder is
located between the unit plug and the main switch (01). The rectangular
fuse box can be opened with a tool. Remove the cord and apply a tool against
the fuse box from below and pull out. See also 3.2 attention.
