6.2 Replacement of parts
6.2.1 Replacement of printed circuit
For the replacement of the printed circuit of the control-box, the cover should be removed
by unscrewing the bolts. unplug the connectors which are attached to the printed circuit.
Now unscrew all M3 bolts and remove the circuit. It is important to fi rst disconnect the
connectors and then unscrew the bolts. attach the new printed circuit in the same way,
but in reverse.
It is wise to use a wrist band with ground cord which is connected with earth (PE). This
because of the of static electricity.
6.3 Cleaning the machine
The frequency of cleaning will depend on the number of times the raw material is changed.
For cleaning the machine the front panel, the mixer chamber, the weighbin and the mixer
should be removed (as described in section 4.2).
Disconnect the electrical power and
air supply.
Clean the machine by using air pressure. Use safety-goggles when cleaning. After it has
been cleaned, put it back together in the reverse way of stripping it.
6.4 Transportation of the GraviMaster
The weigh bin should be removed, before moving the GraviMaster, this can be done as
described in the previous section. The weigh bin should be removed to prevent damaging
the loadcell. The machine can now be transported on a fi rm pallet.
