technology and first-rate quality. They are specially designed to provide made-to-measure
solutions that offer long-lasting performance every single day of their working life.
In making these products Zhermack S.p.A. makes use of the latest design tools, thus ensuring
that all finished machine is as functional as possible. Use of only top-quality materials and
thorough testing aimed at providing maximum user safety are an Zhermack S.p.A. constant,
making our products safe and internationally competitive.
The SQM 25 N and SQM 25 SN model trimmers have been designed to grind and trim
odontotechny products. The SQM 25 N features an innovative water cooling and washing
system which is always on and automatically controlled by a solenoid valve; the grinder disc
allows the user to carry out precision trimming, thus allowing the technician to machine the
piece exactly as required.
The SQM 25 SN, instead, is equipped with a diamond-tipped disc which allows dry (waterless)
use of plaster models. The long-lasting diamond-tipped disc is especially suitable for hard
plasters, linings and resins. Both model trimmer versions have a Start and Stop button and can
be fixed to the work top.
The SAB 1000 G plaster dust aspirator is designed for use with the SQM 25 SN version only.
Offering high performance and reliability, the aspirator has a protective casing to provide
maximum safety. The aspirator also has a by-pass motor, a supplementary switch and comes
complete with a special filter for filtration (up to 0.3 mm) and collection of plaster (or other
powdery residues).

It is recommended that you keep the original packaging so that, if
necessary, it can be re-utilised; doing so ensures that you do not use
unsuitable packaging materials during transport and mounting which
might lead to accidental damage (see section 5.3).
5.1 WARNING
5.2 PACKING AND UNPACKING
All the material is thoroughly checked by the Manufacturer prior to shipment. When you
receive the goods make sure they have not been damaged during transit and that no-one has
tampered with the packaging and removed any of the parts contained therein.
Should you note any damage or missing parts please inform your Dealer and the shipping
carrier immediately: take photographs and send them on to both dealer and carrier.
The packaging (in the example in figure SQM S25 N), consisting of a cardboard box with
internal expanded plastic padding, contains:
• the model trimmer and/or aspirator and any components;
• this Use and Maintenance Manual.
CHAPTER 5: TRANSPORT AND MOUNTING
To prevent any injury to persons or damage to things always proceed with the
utmost care and attention when mounting the machine. Observe all the
precautions and instructions contained in the following paragraphs.
If the unit is to be transported by courier, the postal service or rail it is
recommended such shipments be insured.

If it is necessary to move the model trimmer and/or aspirator you must:
1. disconnect the machine from the mains power supply;
2. for the model trimmer: after cleaning the machine thoroughly (see Chap. 8) detach the
aspirator connector and close the main switch flap.
2a. for the aspirator SAB 1000 G: empty the residue from the bag (see Chap. 8) and detach the
model trimmer connection hose.
3. gather all its accessories together.
4. grasp the machine by its base and make sure it is always kept in vertical position.
To this end always bear in mind the weight and dimensions of the unit being handled (see
section 4.2.2) to prevent any damage caused by inobservance of these measurements.
5. Pack the machine in its original box or, if this is not possible, take all the necessary
precautions to protect the machine against knocks or drops, in that the goods are transported at
the owner's risk.
5.3
TRANSPORT AND MOUNTING
Failure to observe the above exonerates the Manufacturer from any
liability concerning machine malfunction and consequently renders the
Warranty null and void.
When shipping/delivering the machine to your Authorised Servicing Centre
always enclose a copy of the purchase document and a copy of the properly
compiled ID form.
5.4
ELIMINATION / DISMANTLING
When disposing of the packaging materials the user must comply with the standards in force
in his/her country regarding the following materials:
• Wood/paper: non-polluting materials, but must be recycled properly.
• Polystyrene/plastic: pollutants which must not be burnt (toxic fumes) nor dispersed into the
environment, but disposed of in compliance with the standards in force in the country of use.
If the machine is to be dismantled the user must, in compliance with EC directives and the laws
in force in the country of use, effect elimination and recycling of the following materials:
• Plastic and glass parts, insulated electrical wiring, rubber parts.
• There are no toxic or corrosive parts.
This product must not be disposed of as household waste but rather, when
no longer used, must be collected separately according to EC Directive
2002/96.

6.1 WARNINGS AND PRECAUTIONS
CHAPTER 6: INSTALLATION AND FIRST-TIME USE
So as to provide greater clarity the numbers given in the diagrams in this
chapter correspond exactly to the numbering in the Components Table (Ch. 3).
Work area lighting is an important factor in both personnel safety and the
ultimate quality of the work being done. In Italy lighting must comply with a
Ministerial Decree Law that clearly defines minimum lighting requirements.
In other countries lighting requirements form part of the accident prevention
and workplace hygiene standards.
Before proceeding with installation make sure that all relevant safety conditions prevail and
follow the instructions below carefully.
6.3 REQUIRED WORK SPACE
Choosing a good workplace with an appropriate amount of space available for machine
installation is an essential factor in personnel safety, the quality of the work and proper
maintenance. This zone must not only be spacious enough to allow for optimum machine
operation but must also be well illuminated, aired, not dusty and not exposed to direct sunlight.
Note also that the unit must be positioned so the connection plug can be handled/manipulated with
ease.
6.2 PERMITTED AMBIENT CONDITIONS
Unless stated otherwise at the time of order the machine will be configured to operate properly
under the following ambient conditions:
Ambient conditions other than those listed above may cause malfunctions or sudden
breakdowns. Lighting in the installation area must be sufficient to provide good visibility at every
single point on the machine.
More specifically, luminosity must not be less than 200 lux, lighting must be as uniform as
possible and there must be no reflected light as this could dazzle the operator.
The machine must not be used in workplaces having an atmosphere which is
explosive and/or at risk of fire as it has not been designed for use in such areas.
Nevertheless, should a fire accidentally break out follow the procedure described
in paragraph 2.4.
Place of Use Indoors
Altitude Up to 2000 m
Working temperature From 5°C to 40°C
Humidity Max 80%

6.3.1
Worktops
The machine (in the illustration an SQM S25 SN) has been designed to operate resting and/or
fixed on a rigid, flat, level worktop.
Workshop furniture or modelling benches may be used for this purpose (with the former the
worker is in a standing position and with the latter in a sitting position); check their stability
beforehand. The SAB 1000 G aspirator has been designed for direct on-floor placement.
6.4
CONNECTING UP TO THE POWER SUPPLY
The user must provide a power connection with relative socket near the machine installation
point. The user must also install an adequate electrical circuit breaker upstream from the socket
as well as efficacious overload/indirect contact safety devices.
Connection is effected via the safety plug (16A, in compliance with European standards) at the
end of the power lead: this must be inserted in the mains socket.
When connecting check:
• that mains voltage and frequency are as indicated on the identification plate (incorrect power
supply voltage may damage the machine);
• that the mains supply has a proper, efficient earth connection.
It is forbidden to tamper with the power lead and its plug. When replacing them
owing to damage and/or wear please contact an Authorised Service Centre.
A proper earth connection is compulsory. Should it temporarily be
necessary to use an extension lead the latter must comply with the
standards in force in the country of use.
