2.2.1 Read carefully before use
In combination with: LaboUI, LaboForce-50, LaboForce-100, LaboForce-Mi, LaboDoser-100.
Ignoring this information and mishandling of the equipment can lead to severe bodily injuries and
material damage.
Specific safety precautions - residual risks
1. The operator must read the Instruction Manual and, where applicable, the Safety Data
Sheets for the applied consumables.
2. The machine must be placed on a safe and stable table with an adequate working height.
The table must be able to carry at least the weight of the machine and the accessories.
3. Connect the machine to a cold water tap. Make sure that the water connections are leak-
proof and that the water outlet is working.
4. Keep clear of rotating parts during operation. When you perform manual grinding or
polishing, be careful not to touch the disc. Do not try to collect a specimen from the tray while
the disc is rotating.
5. To prevent specimens from detaching from the specimen holder, make sure that the

3 Getting started
3.1 Device description
LaboPol-30 is for materialographic preparation (grinding/polishing) using preparation discs of
230, 250 or 300 mm in diameter.
LaboPol-30 is for manual preparation when used with LaboUI.
LaboPol-30 is for semi-automatic preparation when used with LaboForce-50, LaboForce-100 or
LaboForce-Mi. The specimen mover is always installed on the left side of the machine.
3 Getting started
LaboPol-30 13

The operator selects the grinding/polishing surface and the cooling fluid/abrasive suspension to
be applied.
Cooling water is applied when the operator opens the water tap. Other fluids are applied
manually or by a separate dosing unit.
With LaboUI the operator holds the specimens during the preparation.
With LaboForce-50, LaboForce-100 and LaboForce-Mi the operator places the specimens in a
device, the specimen mover plate or the specimen holder.
With LaboUI, LaboForce-50 and LaboForce-Mi the operator sets the rotation speed of the
preparation disc before starting the process.
With LaboForce-100 the operator sets the process parameters before starting the process.
The machine must always be used with the splash guard in place.
The splash guard for manual preparation is supplied with the machine. (For the 300 mm
diameter disc)
The splash guard for other types of preparation must be ordered separately.
The operator starts the machine by pressing the Start button on the control panel.
With LaboUI and LaboForce-50 and LaboForce-Mi the operator stops the machine by pressing
stop on the control panel.
With LaboForce-100 the machine stops automatically when the process is completed.
The operator cleans the specimens before the next preparation step or inspection.
We recommend that an exhaust system is applied when alcohol-based suspension or lubricants
are used.
If the emergency stop is activated, the power to all moving parts is cut.

3.4 Struers knowledge
Mechanical preparation is the most common method of preparing materialographic specimens for
microscopic examination.
The specific requirement of the prepared surface is determined by the particular type of analysis or
examination.
Specimens can be prepared to the perfect finish, the true structure, or the preparation can be
stopped when the surface is acceptable for a specific examination.
Hint
For further information, see the section on Grinding and Polishing on the Struers
website.
