6.2Replacement of parts

6.2.1Replacement 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 first 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.

6.3Cleaning 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.

6.4Transportation 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 firm pallet.
