MAINTENANCE:
1. Keep your sandblaster 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 sand hose and fittings. The sand metering valve, manifold and all parts
after the sand is ejected from the tank are subject to rapid wear, due to the flow of
abrasive sand. Watch especially for leaks, blistering bulging or thinness of the hose.
Replace any parts which appear worn.
ABRASIVE SELECTION:
The kind of sand you choose will greatly influence the amount of time needed to clean a
given surface area. Sandblasting materials include silicon carbide, alumina, silica sand and
others.
Be sure that the sand you use is thoroughly dry. Damp sand can cause clogging of your
sandblaster.
While you may reuse abrasive sand, remember that sand does wear out. After using, sand
becomes smoother and rounder, thus reducing abrasive effectiveness.
Reusing abrasive sand 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 sandblasting.
Adjust air pressure with the air pressure adjuster (#9). Adjust sand flow with sand metering
valve (#26).
Watch for sand clogging. Depressurize if necessary and replace the sand with drier or
cleaner abrasive.
