After proper nozzle selection insert nozzle into retainer base. Set again
stwasher and slide retainer nut over nozzle and tighten by hand.
2. The Pressure Blaster is equipped with a unique semi-automatic pull-up
closure design. 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. When ready to pressurize
container, pull up closure and turn on incoming air. The internal air
pressure will seal the closure.
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.
AIR ABRASIVE SUPPLY REQUIREMENTS
Abrasive blasting requires a large volume of air at high pressure. The
efficiency of your abrasive blaster can be adversely affected by the use of
too small an air supply hose,insufficient air pressure or an overly large
