Mini polishing box «Gorbea»
NOTE: Carefully read this manual. It contains
important 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.
ref. 080508 is a simple polishing box especially
designed to polish and grind small items in the field of
dental mechanics.
Installation
1. Carefully unpack the unit. Check that it has not
sustained damage during shipment.
2. Place the unit on a flat and firm surface remote from
any source of heat or vibration.
3. Both brush holders are factory assembled and
adjusted. They must not be disassembled.
4. Connect the unit to an adequate earthed power source
according to the label.
Fitting the brush to the brush holder
1. Insert the brush into the brush-holder, ensuring that
the brush-holder shaft is perpendicular to the plane
of the brush.
2. Screw the brush onto the brush-holder as tightly as
possible by hand.
3. Visually check that the brush-holder shaft is
perpendicular to the plane of the brush by spinning
the assembly in your hand.
4. Start up the unit: the spin of the motor will reveal
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.
5. Remember that the friction torque produced during
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 an adequate earthed power source
according to the label.
 Press the green button (E) to connect the power.
 Press the switch (A) to turn the light on.
 Select the desired spin speed (2000-5000 rpm)
turning switch (B).
 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;
- 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
polisher motor is cut off it stops, but when power is
restored the machine might start up unexpectedly and
anyone manipulating the motor shafts at the time
might suffer injury. To prevent this Talleres
Mestraitua, 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.
 Clean the unit after using it.

Maintenance and cleaning

To ensure a long, trouble-free useful life for your unit,
proceed as follows:
 To clean the motor and base used a cloth. Never use
alcohol, solvents or other inflammable liquids.
 Never immerse the unit in any liquid.
 If you notice unusual noises or vibrations, send the
unit to your technical assistance service.
 This unit is designed to work correctly on the four
rubber legs.
Precautions
 Before use, check that the unit is connected to an
adequate earthed power source according to the label.
 Discard any cracked or damaged brush or grinding
wheel: if these elements break during operation, they
could cause serious accidents.
 Before starting work, ensure that the brush-
holder/wheel holder is firmly attached to the motor
shaft.
 When handling workpieces, use safety goggles,
gauntlets, a face mask and the safety shields.
 Do not allow children or unskilled personnel to
handle the unit.
 If the motor shaft locks during normal operation,
disconnect the unit from the mains before attempting
to release it by turning it manually.
 Never polish, brush or grind materials which may
give off particles which are toxic if inhaled.
 Before starting to polish or grind a workpiece, check
the motor spin direction: the attack angle depends on
this direction.
 Never use the unit close to solvents, alcohol or other
inflammable materials. Take all possible precautions
when grinding materials which may give off sparks.
