2.Connect an appropriately sized air supply hose to the air inlet. See Technical Specifications, page 45.

NOTE: Make sure the air supply meets the appropriate air flow requirements. See Technical Specifications, page 45.

4.Connect the blast hose, hose restraints, control hoses, and coupler pins.

NOTE: Make sure to properly install hose restraints and coupler pins to the quick-coupler and the air line. If the holes on the quick-coupler do not align, there is something wrong and the two couplers are not compatible. DO NOT TURN ON THE AIR. Seek help to get the situation resolved.
