OPERATION AND MAINTENANCE The Model 115 Gun in normally used for touch-up, stenciling, and small work spraying. CONTROLLING THE FAN SPRAY The fan spray for an external mix nozzle set-up is easily controlled by means of the side port control assembly (17).

These parts are carefully machined and any damage to them will cause a faulty spray. ! If either the air nozzle or fluid nozzle is damaged, the part must be replaced before a perfect spray can be obtained. TO REPLACE FLUID PACKING Remove the fluid control screw (21), spring (23) and fluid needle (3). Then remove the…
