4.2 Operation

4.2.1 Handling the tool. Grip the valve handle with one hand and the adapter boot with the

other hand. The main body of the tool must remain more or less upright, with the abrasive

container pointing downward. The Educt-O-Matic has a swivel blast head which permits

blasting in any direction (up, down, sideways) without rotating the main body. Hold the

adapter boot rmly against the surface being blasted to insure a proper seal and prevent

abrasive from escaping.

4.2.2 Dual action of the valve handle. Note that the control valve (see drawing 2.1) has

two seats. The rst 3/16″ of the valve handle’s travel opens the primary seat only and the

Educt-O-Matic functions essentially like a vacuum cleaner. This is because the primary seat

supplies air to the suction jet only. Squeezing the handle further opens the secondary seat

as well. Air is supplied to the blast jet and blasting begins.

For best abrasive recovery, hold the valve handle in the “suction only” position for two

or three seconds after blasting. This will recapture any abrasive that happens to be in

the blast head at the time. The “suction only” position can also be used for loading. Place a

handful of abrasive on any level surface and simply suck it into the tool.

ATTENTION!

ALWAYS TURN THE AIR OFF AT THE SOURCE WHEN THE EDUCT-O-MATIC

IS NOT IN USE.
