gun. The flat on the seal must align with the gun's

engaged into the hole in the gun body. Reinstall the

nm (13–15 ft-lbs). Don't over torque the fluid
nozzle. A drop or two of lubricant on the fluid nozzle
threads and air separator threads insures smooth

body, seating in fluid nozzle.

knob until it stops. Back it off 1/2 turn and
