Before You Begin
1. Check the tightness of the tank covers. The O-ring seals must be firmly seated
against the tanks.
2. Check to see that the ends of the tank vent hoses are inserted into the back of the
workstation or dust collector hose.
3. Depress the tank cover flapper (see Figure 3-3), and using the funnel from the
accessory kit, pour the selected abrasive powder into the appropriate tank, filling it at
least half full.
Do not overfill.
Tap the flapper as it closes so that any powder on it
will be dislodged into the tank and not interfere with sealing of the O-ring.
4. Reposition hoses in the pinches by about 2". It should become a habit to move the
hoses through the pinches on a regular basis. This will allow the pinch to squeeze
the hose in a different spot, increasing the life of the hoses.
5. Maintain a generous loop in the abrasive hose between the abrasive pinch valve and
the hose connection on the rear panel.
