OPERATING INSTRUCTIONS
OPERATING TECHNIQUE:
1. Connect air hose to air inlet valve. Manufacturer recommends using
minimum incoming air hose of 1/2” I.D. Using an air hose smaller than
1/2” I.D. will restrict air volume and result in poor unit operation. Prior to
Injection of air, be certain air inlet valve and nozzle valve are in the OFF
position. With Deadman Valve closed and filler plug tight, open air inlet
valve allowing air to pressurize. Operating range of unit is 40 to 110 PSI
Note: For proper nozzle selection, refer to nozzle selection chart on page
11. After proper nozzle selection, insert nozzle into retainer base. Set
against washer and slide retainer nut over nozzle and tighten by hand.
2. Manufacturer recommends a fine grade abrasive with granular size
similar to that of table salt. This assures proper flow and reduces the
possibility of nozzle obstruction.
3. With the blaster pressurized and abrasive flow regulator valve at base of
unit closed, open ball valve allowing air to flow through by-pass hose to
base of the unit. Then holding the abrasive hose by nozzle retainer
housing with nozzle directed away from unit and operator, quickly
squeeze the Deadman Valve fully open and adjust the regulator valve at
base of tank to bleed the abrasive into air flow. Slowly open regulator
valve until abrasive material is slightly visible. Once the regulator flow
valve is adjusted to the desired setting, further adjustment should only
be required when changing grade of abrasive material or when a nozzle
with a different I.D. is used. Opening regulator valve too far will result in
a clogged hose or nozzle.
For best performance, the Deadman Valve should be opened and closed quickly
WARNING!
Disconnecting hose while Unit is under pressure could cause serious injury or
death. Use safety lock pins and safety cables in all coupling connections to
help prevent hose couplings from accidental disconnection.
If twist-on type air hose couplings are used, they must be secured by
safety lock pins or wires to prevent accidental disconnection while under
pressure. Hose disconnection while under pressure could cause serious injury.
