Using the Wash Feature

Operation

2. Turn the selector valve to WASH.

The wash feature causes air-driven water (without abrasive) to blast and rinse areas that have already been blasted with abrasive. It is also a convenient feature for flushing abrasive from the blast hose.

NOTICE

There will always be some residual abrasive in the blast hose. Never use the wash feature on any surface other than where you have blasted, or intend to blast. It will affect/dull the surface.

NOTICE

Do not use the wash feature on wood that has been blasted. It could damage the wood and cause the grain to rise. Wait for the wood to dry and then use a broom, brush, or vacuum to remove any residual abrasive.

1. Close the abrasive ball valve.

3.Blast 1 – 2 minutes until the abrasive is cleared from the hose.

4.The equipment is now ready to wash any previously blasted surfaces.
