Figure 7 3 Thompson Valve Abrasive Blaster with pneumatic blast controls 45 2010 Axxiom Manufacturing Inc 8 0 Maintenance and Inspection Instructions A DANGER The abrasive blaster is a Pressurized Vessel Propelled objects will cause serious injury or death Depressurize vessel before performing any maintenance See Section 6 2 For proper operation maintenance should be performed with the assistance of a qualified serviceman 8 1 8 4 46 Blaster Pressure Vessel The ASME Code is a standard covering materials design fabrication and installation Vessel integrity subsequent to purchase is the responsibility of the owner and or user At intervals required by state law and or local authorities the vessel should be subjected to a hydrostatic test as described in the ASME Code Section Division 1 Do Not subject the abrasive blaster pressure vessel to a pneumatic proof test exceeding the maximum allowable working pressure In no case should the hydrostatic test pressure exceed 1 3 times the maximum allowable working pressure MAWP shown on the pressure vessel nameplate 24 Thoroughly clean and dry the vessel before re assembly Moisture or debris left in vessel can cause equipment malfunction Blaster Pressure Vessel Any damage to an abrasive blaster can make it unsafe Inspect the exterior of the abrasive blast vessel daily for corrosion pitting or other damage

14. Con OPEN po CLOSED Figure 5 6 Thompson Valve Abrasive Blaster with electric deadman controls Abrasive Cutoff An optional feature of a Thompson Valve blaster is an abrasive cutoff There are two uses for the abrasive cutoff feature First is to allow blasting air without abrasive This is useful for blowing off abrasive from the item blasted To blast with air only set the abrasive cutoff valve or switch to the off position then press down the deadman lever 12 This will send a control signal to the automatic air valve only therefore only blast air will exit the blast nozzle 11 For the abrasive cutoff to work a second control valve is needed that provides a signal to the Thompson Valve separate of the air signal to the automatic air valve See Sections 9 3 a and 9 3 b The second use for the abrasive is to purge abrasive out of a long blast hose This prevents abrasive from collecting in the blast hose when the blast operation is stopped The abrasive at rest in the blast hose can cause surges when restarting the blast operation Note The a
