LaboForce-Mi is designed to be mounted on Struers’
grinding/polishing machine LaboPol-35 only.
 Remove the black plastic lid from the pre-punched hole on
LaboPol-35.
 Lead the LaboForce-Mi column through the hole, and position
the head of LaboForce-Mi over the turntable of LaboPol-35.
 Remove the two light grey caps from the left hand side of
LaboPol-35.
 Tighten the two screws with the enclosed allen-key.
 Move the handle on the left hand side of LaboForce-Mi up, to
allow the head to move to the uppermost position.
 Mount a specimen mover plate on LaboForce-Mi.
 Mount a grinding/polishing disc on LaboPol-35.
 Press the head down and adjust the distance between
preparation disc and specimen mover plate to about 2 mm by
turning the black knob on top of LaboForce-Mi.
Connect LaboForce-Mi to the female plug on the back of LaboPol-35,
marked specimen mover.
A drip lubricator provides the necessary lubricant during the
preparation process.
 Remove the drip lubricator from its box.
 Loosen the finger screw underneath LaboForce-Mi.
 Guide the bottom plate of the drip lubricator onto the finger screw
and the positioning pin underneath the LaboForce-Mi, and re-
tighten the finger screw.
 Hold the lubricant bottle with one hand and remove the lid.
 Fill the bottle with lubricant.
 Replace the lid and the drip lubricator is ready to use.
To apply the lubricant to exactly the right spot on the preparation
disc, a different length of lubricator tube may be necessary.
300 mm of spare tube is supplied with LaboForce-Mi.
To remove the present tube from the drip lubricator press back the
retaining ring and pull out the tube.
To insert the new tube simply press it into the hole in the retaining
ring.
Use a pair of scissors to cut to the correct length.
Setting up LaboForce-Mi

2. Operation
 Unlock LaboForce-Mi and let it move into top position.
 Turn LaboForce-Mi to the left over the edge of LaboPol-35.
 Place the specimen mover plate under the column, align the pin
and the slot and press it upwards.
 Move LaboForce-Mi back into position, press it down and lock
the handle.
As specimens must fit the holes in the specimen mover plate
quite accurately, the specimen mover plate must be changed
when samples of another size are prepared.
To remove a specimen mover plate, turn the plate clockwise to
release it.
 Lift the thrust pad on the adjustment screw to make room for the
specimen.
 Place the specimen in one of the holes of the specimen mover
plate and lower the thrust pad.
There are two ways to adjust the force.
Press the release knob  and move the column  up or down
to approximately the correct force.
Adjust the force by turning the column . The marks  on the spring
loaded column correspond to the actual force in Newton as stated
below:

To avoid directional abrasion of the specimens during preparation
LaboForce-Mi is equipped with the ability to carry out forced rotation
of the specimens.
Simply move the angled stainless steel pin down and press it into the
clips on the left hand side of LaboForce-Mi.
If forced rotation is no longer required move the pin back into the
upper position and secure.
Operating LaboForce-Mi
Important
The specimens should run close to the edge of the preparation disc.
The distance should be about 2 mm.
Important
To turn the specimen mover disc use the start and stop keys of
LaboForce-Mi. Do not turn the specimen mover disc manually.

2. Trouble-Shooting
Error Cause Action
The machine does not
operate when the start
switch  is pressed.
- LaboPol-35 is switched off or not
connected to the power supply
- LaboForce-Mi is not connected to
LaboPol-35
- Make sure that LaboPol-35 is
working correctly
- Connect the plug from
LaboForce-Mi to the female
plug at the back of LaboPol-35
The force adjustment
screw is rotating when
a specimen is passing
the centre of the
preparation disc.
The friction between the force adjustment
screw and the rubber foot is too high
Add a drop of oil in the rubber
foot to reduce the friction.
