another side.
ATTENTION!
DO NOT TIGHTEN UNIONS TOO MUCH, IN PARTICULAR THE UNIONS OF RC HANDLE. IT
CAN DAMAGE SOME COMPONENTS AND CAUSE AN AIR LEAK.
3. Ensure that all connections are leak-proof.
4. Ensure that all connections on the RC valve and RC handle DMH are connected
properly, and according to the color. Transverse joint will make the system non-
operational.
5. Fix RC handle DMH to the blasting hose, using clamp bands right behind the nozzle
holder.
6. We recommend to connect a twin hose Twinline to the blasting hose using clamp bands
every 1.5 m.
ATTENTION!
ALWAYS USE AN OIL-MOISTURE SEPARATOR WHEN USING REMOTE CONTROL SYSTEM TO
PREVENT WEAR ON RC VALVE.
BESIDES, AN OIL-MOISTURE SEPARATOR OPTIMIZES ABRASIVE BLASTING OPERATIONS.

8. Start compressor and increase pressure and temperature up to operational values.
9. Open the ball valve at machine compressed air line (the handle of the open valve
should be parallel to the compressed air line).
10. Open the safety ball valve 14 (Fig.2.1).
11. Close metering valve FSV by setting adjusting handle in the central position.
12. Connect compressed air hose to hose coupling of the machine. Compressed air hose
diameter should be at least 1.1/4”. Lock hose coupling with a safety clip or wire.

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
