Lorraine - Next to the knob, is there may be a spring that you can pull back towards the knob. If so, after you loosen the knob, pull the spring back toward the knob and hold it while turning the base.

I have a hitachi nr90ae that will not fire. Depress nose and trigger and gets nothing. What's next?
Remove nails and air supply. Firmly depress safety foot against work with trigger depressed and make sure that firing pin is pushed all the way in. If firing pin is being activated by safety foot most likely problem is stuck cylinder or head valve. If the gun has been dropped the cylinder my jam. Remove the head and make sure that the cylinder and or headvalve moves and that the driver is not stuck in place. Good luck
