Page 18: The Blast Pattern
The blast pattern The cast grooves on the control cage show the position of the control cage opening. The following adjustment standard value is valid: the control cage opening is approximately opposite to the throwing angle. The abrasive grain size plays an important role here. Different types of abrasive have different throwing characteristics due to their different weights and frictional resistance. - Page 19 Now the blasting procedure can be started. When a concrete surface is to be blasted, check the blast pattern again after some meters and re-adjust slightly if necessary. WARNING! Never loosen the cage clamps lever or try to adjust the blast wheel cover when the machine is in operation!!
