utmost care and attention when mounting the machine. Observe all the
precautions and instructions contained in the following paragraphs.
PACKING AND UNPACKING
5.2
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.

MAINTENANCE AND USE MANUAL
CHAPTER 6: INSTALLATION AND FIRST-TIME USE
WARNINGS AND PRECAUTIONS
6.1
Before proceeding with installation make sure that all relevant safety conditions prevail and
follow the instructions below carefully.
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).
PERMITTED AMBIENT CONDITIONS
6.2
Unless stated otherwise at the time of order the machine will be configured to operate properly
under the following ambient conditions:
Place of Use Indoors
Altitude Up to 2000 m
Working temperature From 5°C to 40°C
Humidity Max 80%
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.
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.
REQUIRED WORK SPACE
6.3
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.

Worktops
6.3.1
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.
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.

PURPOSE OF THE MACHINE / IMPROPER AND FORBIDDEN USE
6.8
The SQM 25 N and SQM 25 SN model trimmers have been designed and built to grind and
trim linings, odontotechny items in plaster and resin.
Using the machine for any purpose other than that described in this Manual
shall be considered improper and thus forbidden.
Improper use renders the Warranty null and void and Zhermack S.p.A. shall not
be liable for any damages to objects, workers or third parties.
The main reasons for which the Warranty may be rendered null and void are given in section
2.2 and in the "Warranty Certificate" enclosed with this Manual.

WARNINGS
7.1
The machine must not be used with any of its parts disassembled: before using
the machine make sure that all its components are properly in place.
To ensure that work is done in absolute safety always make sure that you
follow the described procedures with caution.
To provide greater clarity the numbers given in the diagrams in the following
paragraphs correspond exactly to the numbering in Chapter 3 in the
"Machine Description" section.
SAFETY SYSTEMS
7.2
In compliance with international accident prevention standards (EEC directive 89/392) the
machine features several safety devices such as fixed and mobile guards to shield moving
parts, thus guaranteeing worker safety when the machine is in use.
USING THE SQM 25 N
7.3
Fig. 10 : After installing the machine (see Chap.6),
prepare the item to be worked and position it on the
support top (4).
The support top has been designed
so that trimming can be carried out
with fixed and/or mobile orthodontic
supports.
Fig. 11 : Adjust the orthodontic support (fixed and/or
mobile) positioned on the top (4) via the adjuster
knob (5).

Water flow (which exits from a small tube at the
centre of the emery disc) is regulated via an adjuster
knob (6).
Figure 13
Because the machine has a water-fed cooling - washing system (always on and
controlled automatically by a solenoid valve) the water infeed tap must always
be open.
Fig. 14 : Press the red STOP button (2) on the main
switch to stop work.

If, during work, the mains power suddenly goes off and then comes back on,
the machine shuts down automatically. To restart just press the green START
button (3).

USING THE SQM 25 SN
7.4
The SQM 25 SN model trimmer does not have a water cooling system; it also differs from the
SQM 25 N in that it has a diamond-tipped disc (as opposed to an emery one) to allow dry use
of plaster models.
Fig. 15 : After carrying out machine installation (see
Chap.6) and positioning the item to be worked on the
support top (4) via the adjuster knob (5), press the
green START button (3) on the main switch assembly
to start working.

main switch button (B), unless, of course, it is already
on.
Figure 16
Fig. 17 : The long-lasting diamond-tipped disc (13)
is particularly suitable for hard plasters, resins and
linings.
All the plaster dust generated by the work cycle is
aspirated and collected in the SAB 1000 G
aspirator.

DISC REPLACEMENT
7.5
When it is necessary to change the disc the SQM 25 N and SQM 25 SN model trimmers are
easily disassembled.
To change a disc (see figure) proceed as follows:
• undo the four lock knobs (1);
• remove the front cover;
• unscrew the disc fixing screw (X);

It is advisable to change the SQM 25 N abrasive disc every 12 months.
RESIDUAL RISK
7.6
Residual risk is:
• a danger that cannot be completely eliminated through design and application of safety devices.
• a potential danger which cannot be highlighted.
The model trimmer generates dust as it works; hence the work itself involves the following
residual risks:
• being hit by jets of dust generated during work;
• work carried out on the machine interior by unauthorised personnel;
• risk of damaging your hands.
Always wear protective goggles when using the machine.
To prevent accidents always observe the instructions in this manual. Should
you have any doubts at all please contact the Manufacturer or your Authorised
Servicing Centre.

MAINTENANCE AND USE MANUAL
CHAPTER 8: MAINTENANCE
EN
CLEANING
The machine exterior can normally be kept clean just by wiping it with a dry cloth. If necessary,
wet the cloth just a little water or use a non-degreasing detergent.
The operator must ensure that the machine is kept clean and free from any foreign bodies such
as dirt, water, non-conducting liquids etc.
The machine must be cleaned at the end of every work session to remove all residues.
Cleaning must be done with the machine at standstill and positioned in a stable manner.
Before cleaning the machine exterior always turn the main switch to OFF. It is
strictly forbidden to clean the machine while it is connected to the mains power
supply.
Never use inflammable, corrosive, alkaline or toxic liquids when cleaning the
machine.
Eye goggles and a face mask must be worn when using compressed air for
cleaning purposes. Do not allow any persons near the machine as they could
be hit by flying dust.
If the model trimmer is to remain idle for a prolonged period it is advisable to disconnect it so as
to prevent the motor overheating.
Replacing the nylon filter bag on the SAB 1000 G
To change the nylon bag filter in the SAB 1000 G aspirator (usually done weekly) proceed as
follows:
• switch off the aspirator via the main switch and disconnect it from the trimmer.
• undo the catches (H) to open the aspirator and remove the motor block (A).
• remove the felt filter (L) and detach the suction hose (F) from the connector.
• remove the filter (I).
When changing the filter make sure no powder gets inside the aspirator; if it does, clean
thoroughly.
• insert new filter.
• reposition the felt motor protection filter (L) so that its edges rest on the aspirator body (E).
• place the motor block (A) on top of the aspirator body (E) and make sure the felt filter is
positioned properly in the motor block.
• close the aspirator by locking the catches (H) back in place.
• re-attach the suction hose (F) to the connector.
• insert the plug (G) in a mains socket, then switch on via the main switch (B).

MAINTENANCE AND USE MANUAL
ROUTINE MAINTENANCE
8.2
Once the machine has been cleaned (see section 8.1) the operator must check for worn,
damaged or loose parts. If any such anomalies are discovered contact your Authorised
Servicing Centre.
Should any of the above anomalies be discovered it is strictly forbidden to
restart the machine before such faults have been set right.
More precisely, should the operator note any defects or problems of any kind whatsoever he/she
must place a warning sign on the machine indicating that maintenance work is in progress and
that using the machine is forbidden (EC-compliant signs can be purchased from the relevant
suppliers).
Routine maintenance, cleaning and proper machine use are essential factors in guaranteeing
long-lasting machine performance and safety.
Equipment safety devices/guards must never be removed except for repair and
maintenance purposes.
Such items must be replaced as soon as the situation which led to their removal
no longer exists and in any case before the machine is used again.
UNSCHEDULED MAINTENANCE
8.3
Unscheduled maintenance (to be carried out by qualified, authorised personnel only) includes
repairs of accidental breakages and replacement of worn or faulty parts.
All electrical and mechanical work must only be carried out by an authorised
Zhermack S.p.A. maintenance technician.
Modifications which alter the machine characteristics from a safety and risk
prevention viewpoint may only be made by the Manufacturer who shall then
issue a certificate stating that the machine conforms to safety
standards. Therefore any modification or maintenance tasks not actually
described in this manual are to be considered forbidden. If the machine is
modified, tampered with or repaired by unauthorised personnel or non-original
spare parts are used the manufacturer is relieved of all responsibility. If a
maintenance task is required but is not described in this manual you must
contact an Authorised Servicing Centre.
