4.1 Set-up

4.1.1 Air supply. The Educt-O-Matic requires 2.5 m³/min at 6.1 bar. Use a ½" (13 mm) or

¾" (19 mm) air supply line; ¾" (19 mm) is preferred. The shorter the air supply line, the

better. An air lter and moisture separator are recommended to prevent clogging of the tool.

4.1.2 Adapter boots. The adapter boots available for the Educt-O-Matic are shown

in drawing on page 13. The standard and master adapters t onto the blast head and

are held in place by friction. The four special boots t the master adapter only.

They too are held in place by friction. Make sure that the boots are properly seated

before beginning to blast.

4.1.3 Abrasives/abrasive loading. Any standard 0,15 mm to 0,40 mm blasting abrasive

may be used. Fragile abrasives such as silica sand are not recommended because of the

rapid breakdown of the abrasive particles which cause excessive dust and nes. Extremely

sharp abrasives such as aluminum oxide and silicon carbide may be used, however the

cutting action of these abrasives will cause excessive wear on the tool. For both efciency

and tool protection, Contracor recommends steel grit or iron grit. To load the Educt-O-Matic

unsnap the abrasive container and place a small amount of abrasive into it. Make sure

the abrasive hose is still inserted all the way into the main body after you do this. The tool

may also be loaded by suction. See paragraph 4.2.3. Never overload the tool. Use as little

abrasive as possible to reduce operational problems and extend tool ife.

ATTENTION!

NEVER BLAST UNLESS THE ADAPTOR BOOT IS WELL SEALED AGAINST

THE SURFACE BEING BLASTED.
