Mestra 080080 Mode D'emploi page 6

English
The Ref. 080080, 080081, 080082, 080083 and
080084 are easily-handled model cutters, especially
designed for use in the dental prothesis sector.
They are structurally similar, with these small
differences:
The Ref. 080080 is fitted with a disc of special
abrasive resins. It has a system for cleaning the
disc with water.
The Ref. 080081 is fitted with a diamond disc that
enhances its durability, and reduces the work
required in facing the models. This unit also has
a disc-cleaning system that uses water.
The Ref. 080082 is fitted with a silicon carbide
disc. It has a system for cleaning the disc with
water. The Ref. 080082 and the Ref. 080083 are
the most powerful MESTRA trimmers.
The Ref. 080083 is fitted with a diamond disc and
also has a dic-cleaning system that uses water.
Same power level as the 080082.
The Ref. 080084 is fitted with a diamond disc, but
the disc is not cleaned with water. This means
greater stability and minimum effort in cutting,
since the plaster does not get dampened.
INSTALLATION OF THE UNIT
1. Carefully unpack the model cutter. Check that it
has not sustained damage during shipment.
2. Position the unit on a flat and firm surface
remote from any source of heat or vibration.
There should be a water tap nearby with a
threaded outlet,
connection (except Ref. 080084).
3. Connect the right-angle end of the flexible tube
onto the nozzle at the back of the unit. Connect
the other end to the water source. To do this,
screw the free nut al the end of the flexible tube
onto the head of the tap (except Ref. 080084).
4. Fit the drainage tube onto the nozzle (F) at the
lower front right of the model cutter. Connect the
other end of the tube to the drainage (except
Ref. 080084). Ensure that the drainage tube has
a certain fall so as to prevent stagnation at the
outlet and thus improve drainage.
5. In the case of the Ref. 080084, connect the
nozzle (F) to an extractor to remove particles
produced during abrasion.
6. The unit has four attachment suckers. In the
design, special attention was given to ensuring
sufficient weight and robustness to prevent
movements during handling, so that it is not
necessary to
components.

as well as a drainage
use additional fastening
EN
7. Connect the unit to a 230 V, 50/60 Hz outlet
with earth.
8. Check that the disc-cleaning system functions
correctly (except Ref. 080084). To do this, turn
on at the main switch, which is on the left side
of the unit. The cutting machine will start up,
and the servovalve controlling the inflow of
water will open.
9. Open the tap at the main water intake. Turn the
cutter control (E) anticlockwise until flow is right.
After a few minutes of operation, check that
there is no leak in the tube connections.
HANDLING OF THE UNIT
1. Adjust the support surface (B) by loosening the
attachment screw. One may choose, depending
on the nature of the work, one of three positions.
Subsequently, tighten the attachment screw (C)
until the support surface is firm.
2. Protect yourself suitably.
Use safety goggles.
-
Use safety gloves.
-
Use a face-mask
-
Proper clothes. No baggy clothes, ties,
-
necklaces, rings, bracelets or elements
that could be hooked by the machine.
Be careful with long hair.
-
Always use the cutting machine with
-
suction (only Ref. 080084).
3. Switch on the unit at the main switch, which is
on the left side. The motor will start up.
4. Open the tap at the main water supply. Turn the
control cock (B) until water flow is as desired.
Flow increases when the cock is turned
anticlockwise (except Ref. 080084).
5. Set the model cutting on the support surface (B).
For higher precision in the cut, the support
surface is provided with reference marks to
facilitate estimation of the model attack angles.
6. When work is over, turn off at the main switch.
7. It is recommended that plaster be removed, after
operation, from the support surface and the front
housing (D) with a damp cloth.
CHANGE OF ABRASIVE DISC
Replace the abrasive element when it is worn or
deteriorated. Always use MESTRA spares, since
only these ensure perfect machine equilibrium and
highest-quality abrasive resin. Proceed as follows:
1. Disconnect the unit from the power supply and
close the main water tap.
