Instruction Manual
Place the specimen holder or specimen mover plate under the
quick coupling.
Press and hold the release button on the column of
RotoForce-4, while guiding the pressure tap of the specimen
holder or specimen mover plate into the coupling.
Turn the specimen holder or specimen mover plate until the
three pins engage in the corresponding holes.
Release the button.
Make sure that RotoForce-4 is set to the correct holder type. If
necessary, change to another type, see Section Setting holder
type.
The position of the specimen holder or specimen mover plate
must be adjusted correctly in relation to the preparation disc to
achieve the best possible preparation results. This is done by
moving RotoForce-4 horizontally.
Generally the specimen holder or specimen mover plate should
be positioned so that the specimens run close to the periphery
of the preparation disc. A distance of about 2-4 mm is
appropriate.
There are three exceptions only: Grinding paper with double
adhesive back, disc with magnetic backing and Petrodisc-M. In
all three cases, the specimens should be protruding over the
edge.
NB: In the case of Petrodisc-M, the specimens should
protrude over the centre of the disc as well. This is done to
achieve the best possible planeness of the specimen, and to
maintain the planeness of Petrodisc-M
