Filling the sandblasting tanks

blasting 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).
Before closing the tank, clean the screw thread on the lid and
the tank and remove any sandblasting residue from the seal.
⇒ Reinstall the tank cover.
Attention: Do not tilt the tank lid when unscrewing.
Always use only clean, dry abrasive of the appropriate grain size
(refer to the accessories).
