We recommend that air pressure in the range of 65-125PSI will provide the best results
MAINTENANCE:
1. Keep your pressure blaster clean and protect from damage.
2. Depressurize after using.
3. When initially pressurizing, check for leaks at the tank top and at all hoses and fittings. Leaking
joints may be repaired by replacing worn or damaged Teflon tape at joints.
4. Check for worn abrasive hose and fittings. The abrasive metering valve, manifold and all parts
after the abrasive is ejected from the tank are subject to rapid wear, due to the flow of abrasive.
Watch especially for leaks, blistering bulging or thinness of the hose. Replace any parts which
appear worn.
ABRASIVE SELECTION:
The kind of abrasive you choose will greatly influence the amount of time needed to clean a
given surface area. Abrasive materials include silicon carbide, alumina and many others.
Be sure that the abrasive you use is thoroughly dry. Damp abrasive can cause clogging of your
pressure blaster.
While you may reuse abrasive, remember that the abrasive does wear out. After using, abrasive
becomes smoother and rounder, thus reducing abrasive effectiveness.
Reusing abrasive may also cause clogging due to debris contained in the mixture from
prior use.
ABRASIVE FLOW ADJUSTMENT
Choose a larger nozzle for a broader spray pattern. Choose a smaller nozzle for more
focused abrasive blasting.
Adjust air pressure with the air pressure adjuster (#9). Adjust abrasive flow with abrasive
metering valve (#26).
Watch for abrasive clogging. Depressurize if necessary and replace the abrasive with drier
or cleaner abrasive.
