2.5 Fill Level Indicator and
Remaining Amount

2.5.1 Fill Level Indicator

The fill level indicator (C, Fig. 3) helps you to estimate
the amount of impression material remaining in the
cartridge. However, after installing a new cartridge or
if the cartridge is very full, the indicator will at first not
be visible.
The indicator will only become visible once the pis-
tons have advanced approx. 25 mm into the car-
tridge.

2.5.2 Remaining Amount Detection

The SYMPRESS is equipped with an electronic fill
level detection. Once there is only sufficient mate-
rial remaining in a cartridge to fill approx. one cast-
ing spoon, the yellow "Residual level" LED (I, Fig. 3)
goes on.

3. Cleaning / Maintenance

To clean the unit, merely wipe it down with a moist
cloth.
Never use cleansers containing solvents.

3.1 Cleaning the Interior

With the pistons retracted, the cartridge bed is easily
accessible for cleaning.
Without a cartridge installed, the pistons can be re-
tracted to the appropriate position to permit the re-
moval of residue from the pressure discs or the spin-
dle covers.
NEVER clean the spindles themselves. The
grease applied to spindles is necessary for
the unit's proper function.
Tip:
Remnants of impression material are most easily
removed with a dry cloth or paper towel.

3.2 Disinfection

Never use superheated steam for
disinfection!
The following products can be used for disinfection:
• Incidur Spray (Ecolab)
• Incides N wipes (Ecolab)
Ensure adequate ventilation following disinfection to
prevent an explosion-prone area.

3.3 Pressure Disc Replacement

The pressure discs are subject to wear as a result of
their rubbing against the inner cartridge wall.
Highly abraded pressure plates can damage the foil
bag.
To replace the pressure plate:
1. Move the pistons to their home position and re-
move the cartridge.
2. Close the unit cover and advance the pistons ap-
prox. 1/3 of their travel path (Fig. 9).
3. Open the unit cover and unplug the power cord
from the wall outlet.
4. Loosen the fastening screw on the desired pres-
sure disc (Fig. 10) and remove the pressure disc
and support disc.
5. Slide support disc onto the spindle (Fig. 11).
6. Install a new pressure plate (Fig. 12).
7. Secure with a new fastening screw (including
washer) (Fig. 13).
8. Close the unit cover and return the pistons to their
home position.
The pressure disc screws have been coat-
ed with a special adhesive to prevent them
from loosening themselves. Always use
new screws when replacing a pressure
disc.

3.4 Unit Cover Replacement

1. Move the pistons to their home position and re-
move the cartridge.
2. Close the unit cover and advance the pistons ap-
prox. 1/3 of their travel path (Fig. 9).

approx. 5 mm (Fig. 14).

The screws have been securely tightened.
There is a risk of injury by the tool when
loosening the screws. Grasp the tool firmly
and hold it securely.
4. Pull the pressure plate forward (Fig. 15) until the
unit cover can be taken out of the hinge (Fig. 16).
