4.2 Abrasive blasting operations
ATTENTION!
DURING A BREAK IN OPERATION ALWAYS OPEN SAFETY BALL VALVE 14 (Fig. 2.1) AT RC
VALVE, OVER AGAINST THE BLUE LINE OF TWIN HOSE (TWINLINE).
RC HANDLE LEVER SHOULD BE NEVER FIXED IN OPERATION POSITION. SUCH FIXING MAY
CAUSE A SERIOUS INJURE..
1. Turn the holder on RC handle and press the lever (start up). The tank is pressurized. Only
compressed air is expelled from the nozzle.
2. Adjust metering valve FSV to provide optimal air-abrasive mixture. The general rule for
abrasive blasting operations: the less abrasive you use, the better.
3. To stop operation you should release the lever (the holder automatically returns to its
initial position).
4.3 Shut-down abrasive blasting operations
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. Turn the holder on the RC
handle and press the lever.
2. If upon completion of operation the machine is left outside you should cover it with
plastic film to avoid ingress of moisture into the tank.
ATTENTION!
AT START UP AND SHUT DOWN ALWAYS CHECK FOR PRESENCE OF WATER IN THE VALVE
BY OPENING THE UPPER BALL VALVE (Fig. 7.1). IF A LARGE AMOUNT OF WATER IS PRES-
ENT, CHECK THE FILTER CAF-3.
