Replacement of abrasive media
To replace used abrasive media, pull the machine forward, lift the internal filtering grid,
remove the cap from the bottom of the working chamber and let abrasive flow out,
collecting it into a proper container.
Replacement of parts subject to wear (pipe, pipe-fittings, microprojector body)
The polyurethan pipe, the connection fitting and the microprojector body where abrasive
flows will inevitably wear out and need to be replaced regularly. To replace the
microprojector body, follow the same instructions specified for the nozzle; to replace pipes
or pipe-fittings, capsize the unit and work under the container. It is also possible to
disconnect each tank for easier operation, simply unscrewing the nuts fixing it to the
housing.
Replacement of tank internal components
Should it be necessary to replace the tank internal components like joints, air injectors,
abrasive outlet pipe, please contact our Technical Service.
Removal of a microblasting tank for repair purposes
The new tank units have been studied to facilitate your task during installation and
removal.
1. Unscrew the feeding pipe ring nut and disconnect the pipe
2. Unscrew the plastic ring nut and remove the microprojector pipe
3. Unscrew the two nuts fixing the tank to the suport, and unclutch the tank.
Procedure for the installation of an additional Modulo tank
• Disconnect the feeding cable and the quick clutch pipe-fitting of the compressed air
• Remove the sheet steel closing the tank seat by making it rotate on itself
• Fix the tank in place by means of the two nuts (adjust it so as to have the blue plastic
pipe-fitting towards the centre of the machine)
• Remove the cap from a free pipe-fitting on the selector and introduce the air inlet pipe
• From inside the working chamber, loosen the screw fixing the microprojector support
lower part and rotate it in order to locate the set up holes
• Drill the membrane of the rubber joint and let the free end of the handpiece pipe pass
through
• Connect the handpiece pipe to the blue pipe-fitting under the tank
• Insert the heater plug into an electric socket.
