Conditions Of Use - Mestra 080164 Manual De Instrucciones

Mini polisher variable speed
NOTE: Carefully read this manual. It contains impor-
tant safety information in the installation, use
and maintenance. If the equipment is used in a
manner not specified by the manufacturer, the
security provided by the equipment may be
compromised.
The Ref. 080164is a simple polishing lathe especially
designed to polish and grind small items in the field of
dental mechanics.
Installation
1. Carefuly unpack the unit. Check that it has not sus-
tained damage during shipment.
2. Place the unit on a flat and firm surface remote from
any source of heat or vibration.
3. If you are facing the ON switch and wish to fit the
brush-holder on the right-hand end of the motor shaft,
select a right-hand (clockwise) thread brush-holder,
so that the friction torque produced when the unit is
used will help tighten the brush-holder. If you wish to
fit it to the left-hand end of the shaft, select a left-
hand (anti-clockwise) thread brush-holder.
4. Put one brush holder each side of the polisher and fix
them with the bolts (B). Make sure they seat only on
the flat face of the shaft.
5. Connect the unit to a 230 V, 50/60 Hz outlet with
earth.

Fitting the brush to the brush holder
Insert the brush into the brush-holder, ensuring that
1.
the brush-holder shaft is perpendicular to the plane of
the brush.
Screw the brush onto the brush-holder as tightly as
2.
possible by hand.
Visually check that the brush-holder shaft is perpen-
3.
dicular to the plane of the brush by spinning the as-
sembly in your hand.
Start up the unit: the spin of the motor will reveal
4.
whether the wheel or brush is off line. If there is
more than 2 mm of slip, dismount and re-fit the
wheel-holder or brush-holder.
Remember that the friction torque produced during
5.
work after a brush is fitted to the brush-holder will
keep it tight. This effect can be favoured by a suitable
workpiece attack angle.

Conditions of use

For best results use the unit as follows:
 Mount an appropriate brush-holder/wheel-holder as
indicated above.
 Connect the unit to a 230 V, 50/60 Hz power source.
 Press the green button (E) to connect the power.
 Select the desired spin speed (2000-5000 rpm) turn-
ing switch (C).
 Before polishing or grinding a workpiece, check the
motor spin direction, as the initial workpiece attack
angle depends on this. Incorrect attack angles can be
extremely dangerous.
 The following protective equipment is recommended
for polishing or grinding:
- safety goggles;
- safety gauntlets;
- face-mask;
- proper exhausters;
- a protective screen suited to the characteristics
and shape of
MESTRAITUA, S.L. recommends Ref. 080200 or
080210 screens, which are especially designed for
use with the polisher.
- Proper clothes. No baggy clothes, ties, necklaces,
rings, bracelets or elements that could be hooked
by the machine.
- Be careful with long hair.
- No objects similar to ropes or chains that Could
be hooked by the machine.
 The unit has a protective system to prevent sudden
start-ups (E). If the electrical power supply to the pol-
isher motor is cut off it stops, but when power is re-
stored the machine might start up unexpectedly and
anyone manipulating the motor shafts at the time
might suffer injury. To prevent this Talleres Mestrai-
tua, S.L. has fitted the unit with an automatic switch
which turns it off in case of a power failure. If this
happens during operation the device will have to be
reset before work can continue.
