Push down while turning clockwise until it won’t turn anymore.\nSet the selector knob to the desired inflation pressure and press the “ON” button.\nThe pump will start making a “whirring” sound while starting inflation at low pressure. When the pressure gets near 1 PSI, the pump will change gears and the pumping sound will change.\nThe pump will turn off when the set inflation pressure is reached. The inflation time to 15 PSI is typically 10-15 minutes. The inflation pressure indicated on the gauge may vary up to 1 PSI from the setting on the selector knob.\nA handheld pressure gauge (sold separately) can be used to verify inflation pressure without air loss. \nInsert the valve cover to protect the valve stem and prevent accidental deflation.\n\nDEFLATION -\n\nTo begin deflation, push in the valve stem and turn clockwise ¼ turn to put the valve in the open position.\nAfter most of the air has escaped, the pump can be used to remove any remaining air.
