- Page 4 400H-A - 450H-A Hardmount Automatic Air Compressor Kit OPERATING INSTRUCTIONS (continued) can cause permanent damage to the unit - this compressor is equipped with built-in pressure switch with a factory set cut-on pressure of 130 PSI (± 5%) and a factory set cut-off pressure of 155 PSI (± 5%). During inflation of tire pressures between 130 PSI to 155 PSI, if you stop inflation, the compressor may not restart. This is completely normal, since inline pressure is greater than cut-on pressure of the pressure switch and less than cut-off pressure of the pressure switch. To restart compressor, deflate tire pressure to below 130 PSI, reconnect tire chuck to tire valve stem and resume tire inflation 6. ONLY OPERATE THE AIR COMPRESSOR IN WELL-VENTILATED AREAS. 7. Compressor performance is also enhanced when operating compressor with vehicle’s engine running. TIRE INFLATION This air compressor comes with 1/4” quick connect stud.
