When the machine is traveling, open the abrasive valves. Observe the ammeter on the display. It may
be possible that one blast wheel takes more amperage than other side. Equalize the load amperage of
left and right blast wheel as close as possible. This is possible by opening or closing one of the shot
valves separate. After having blasted approximately 2 meter, close the abrasive valves, stop the
machine and check the blasted surface.
If one of the ‘hotspots’ must move to the right, turn the cage a little bit to the right.
Never adjust the
cage during blasting
! Loosen the clamp levers of the window indicator and adjust the position to the
right. Tighten the clamp levers after adjusting.
If one of the ‘hotspots’ must move to the left, adjust the window indicator to the left.
