Use drill in percussion or hammer mode. Drill to the specified diameter and depth values specified in the product data sheet. - BLOW AND CLEAN Clear the drill holes completely of dust and fragments by following the procedure shown in the picture. Use the air pump and brush. If the product is not suitable for wet drill holes and the hole is flooded, the water inside must be removed before mortar is injected.
