3.2. Abrasive blasting operations.
1. Feed compressed air to the machine inlet.
ATTENTION!
MACHINE MAXIMUM OPERATING PRESSURE — 12bar.
2. Close the pressurizing ball valve.
3. Upon the signal of the abrasive blasting operator open the ball valve and feed
compressed air into the machine line. The tank is pressurized. Only compressed air is
expelled from the nozzle.
4. Adjust metering valve FSV to provide optimal air-abrasive mixture. The general rule for
abrasive blasting operations: the less abrasive you use, the better.
5. To stop operation close the compressed air feed ball valve and immediately open the
pressurizing ball valve to relieve pressure in the tank.
3.3. Abrasive blasting operation shut-down.
1. Remove the remains of abrasive from the tank. To do this disconnect the nozzle
and point the hose into a suitable container for the abrasive remains. Close the
pressurizing ball valve and open compressed air feed ball valve.
2. If upon completion of operation the machine is left outside you should cover it with
plastic lm to avoid ingress of moisture into the tank.
