7.2 Beginning the Blasting Operation (See Figure 7.2)
7.2.1. The Mini Abrasive Blaster must be properly setup and all operating personnel must be
thoroughly trained before beginning the blast operation. All operators must completely
read and understand all sections of this manual before beginning the blast operation. See
the pre-operation setup procedures given in Section 6.0.
7.2.2. Perform the required inspections and maintenance before beginning the blast operation.
See the instructions given in Section 8.0.
The Mini Abrasive Blaster is a Pressurized Vessel. Propelled objects will cause serious
injury or death. Depressurize vessel before performing any maintenance. See Section
6.2.
7.2.3. Open the choke valve (#13). Leave the choke valve completely open at all times while
blasting. Close the choke valve only for the “choke” procedure (see Section 11.3.2.). Do
Not blast for long periods with the choke valve partially closed since this will cause
excessive wear in the Thompson Valve (#14).
7.2.4. For initial startup the Thompson Valve® (#14) should only be partially open. Turn the
valve knob clockwise to completely close, then turn counterclockwise about four turns
to partially open. The best setting for the valve varies depending on abrasive type, blast
pressure, and nozzle size; therefore, it may take more than one adjustment to achieve the
desired air/abrasive mixture. Further adjustment can be made later as needed.
7.2.5. Close the blowdown ball valve (#4). The ball valve is closed when the handle is
perpendicular to the body (See Figure 7.2).
7.2.6. Pull the popup head (#5) up against the gasket (#6) and securely hold the popup in
position by maintaining a tight pull on the cable. See Figure 7.1
7.2.7. Slowly open the inlet ball valve (#3). This will pressurize the abrasive blaster and
supply air to the deadman controls (#12 & #15).
7.2.8. Check the popup, handway, hoses, and piping for leaks while the blaster is pressurized.
Periodically check for leaks thereafter.
7.2.9. The following steps are for abrasive flow setting which may require several adjustments
and testing of the blast flow. It is recommended that testing of the blast be made on a
test piece so not to damage anything of value.
7.2.10. With one hand grip the blast hose assembly (#10) and with the other hand press in the
deadman safety button. To begin blasting, aim the blast nozzle at the object to be
blasted, then firmly press down the deadman lever (#12). Air and blast abrasive will
flow into the blast hose and out of the blast nozzle (#11).
Do not aim blast nozzle towards yourself or any person. System malfunction can cause
accidental start up and result in injury to personnel.
