3. Ensure that all connectionsare leak-proof.
4. Ensure that all connectionson the RCvalve and RChandle DMHare connected
properly, and accordingto the color. Transverse joint will make the system non-
operational.
5. Fix RChandle DMHto the blastinghose, using clamp bands right behind the nozzle
holder.
6. We recommend to connect a twin hose Twinline to the blastinghose usingclamp
bands every1.5 m.

7. Ensure that compressor is positioned out of the abrasive blastingoperations zone on
downwind side.
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 safetyball valve 14 (Fig.2.1).
11. Close meteringvalve FSV-0 bysettingadjustinghandle in the central position.
12. Connect compressed air hose to hose coupling of the machine. Compressed air hose
diameter should be at least 1/ 2”. Lock hose couplingwith a safetyclip or wire.

1. Turn the holder on RChandle and pressthe lever (start up). The tank is pressurized.
Onlycompressed air is expelled from the nozzle.
2. Adjust meteringvalve FSVto 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 automaticallyreturns 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 RChandle and press the lever.
2. If upon completion of operation the machine isleft outsideyou should cover it with
plastic Àlm to avoid ingress of moisture into the tank.
