Filling the Sandblasting Tanks

Attention: Never press the foot switch during filling.
Even though the manometer may indicate pressure, the sandblasting tanks are only
under pressure if the foot switch is engaged.
• Add abrasive up to the maximum fill level (the point where the tank jacket thickens just below
the thread).
• Reinstall the tank cover.
Before closing the tank, be sure to clean the threads in the cover and the tank to remove
any abrasive residue.
Caution: Do not tilt the tank lid when unscrewing.
Always use only clean, dry abrasive of the appropriate grain size (refer to the accessories).
The sandblasting unit is now operational.
