unit (Fig. 10), then plug the power cord into the
wall outlet (Fig. 11).
2. Switch the unit on (Fig. 12).
4.3 Adjusting the Operating
Pressure
1. Select the sandblasting tank (Fig. 13)
>>> only on the 2-tanks version.
2. Adjust a blasting pressure of 1-6 bar [14.5–87
psi] (Fig. 14). The pressure is displayed on the
manometer (Fig. 14a). The pressure adjustment
applies to all sandblasting tanks (on the 2-tanks
version).
4.4 Filling the Sandblasting
Tanks
Never press the foot switch during filling.
Before closing the tank, be sure to clean the
threads in the cover and the tank to remove
any abrasive residue.

pressure, the sandblasting tanks are only
under pressure if the foot switch is engaged.
1. Unscrew the tank cover (Fig. 15).
2. Add abrasive up to the maximum fill level (the
point where the tank jacket thickens just below the
thread) (Fig. 16 + 17). Make sure the abrasive be-
ing used is compatible with the sandblasting tank.
3. Reinstall the tank cover (Fig. 18).
Caution: Do not cross-thread the cover.
Always use only clean, dry abrasive of the appropri-
ate grain size (refer to the accessories).
The sandblasting unit is now operational.
