8 Operation
8.1 General Operating Instructions
All instructions for using the unit, whether in verbal or written form, are based on our
own experience and experimentation and can only be regarded as guidelines.
All abrasive tanks are colour-coded to match the pencils in the abrasion chamber. Thus, if
you use the blue pencil, it will be fed with abrasive from the blue tank.
The instrument will operate only with the observation flap closed. A safety switch
cuts power to the system if the flap is open.
8.2 Filling with Abrasive
The instrument must be switched off before you fill it.
The tanks can only be opened after the pressure has been released. You do this by
pressing the coloured point in the lid until you no longer hear air coming out. The lid can
then be unscrewed and the container filled with abrasive.
Pay attention of the maximum filling: the receptor nozzle has to be free of material.
All tanks accept all grain sizes. Make sure that the grain size of the medium being added
matches that of the material already in the tank.
The nozzle and the grain size must also match. You should use a 0.8 mm nozzle when
working with glass beads. A 1.2 mm nozzle is recommended for use with irregular bead
sizes. Before replacing the lid, make sure that the thread and sealing surfaces are free of
abrasive. The instrument is ready for use when all tanks have been sealed.
