The system pressure must be manually relieved to prevent the system from starting or spraying 1.
Page 6 Preparation Grounding and Electrical Requirements System Setup 1. Connect the hoses and gun as shown See Fig. 6. WARNING Improper installation or alteration of the grounding plug will result in a risk of electric shock, fire or explosion that could cause serious injury or death.

Lift the hopper straight (adapter included) to the auxiliary air compressor port up off the unit.
Page 8 Preparation Operation Characteristics Always start the system with the compressor air relieved. How to relieve compressor pressure: Be sure the gun air valve (423) and air restrictor valve (424) are open. This relieves compressor air every time you shut off the system. See Fig. 9. Air bleeds from the gun nozzle when the gun air valve (423) is open.
