tible.

Connection to suction device

• Plug the suction tube from the extraction unit to the suction pipe (20).
• For suction devices with automatic activation: connect the mains plug from the sandblasting
unit into the user socket on the suction device.

Adjusting the Operating Pressure

• Activate the foot switch.
• Set the sandblasting pressure (1 - 6 bar / 14,5 - 87 psi) at the pressure regulator (7). The

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.

• Cobra (Renfert GmbH)
• Rolloblast (Renfert GmbH)
• ROCATEC (3M ESPE)
Sandblasting materials from other manufacturers may be used providing the grain size, grain shape and degree of
purity comply with the above mentioned materials. The company Renfert GmbH assumes no liability for function and
durability of the units if other sandblasting material is used.

Do not operate the foot switch during tank selection.
• Take the respective hand piece from the selected blasting tank (see coloured marking).
